Re: [ECOLOG-L] Amazing Gorilla Footage....

2012-08-25 Thread Amartya Saha
I don't know specifically about Uganda, but oftentimes forest dwellers are 
ejected in the process of creating a protected area, and not given any viable 
alternatives, have no choice but to settle on the outskirts and somehow make 
ends meet. These people are then haplessly used by poaching mafia. Local 
conservation plans hinge upon developing income alternatives for them.
 
At the same time, as Taal points out, the mafia will always have ways to poach, 
as long as the demand stays strong. For instance it is known that rhino horns 
are sold in chinese medicine shops, but are there any agencies who can shut 
that down under CITES? Do governments care, and have the clout to enforce 
international laws inside a country which may lash back saying disallowing old 
codgers to get an illusion of youth with powedered rhino horn is meddling in 
cultural affairs? It seems like that's where. All action stops. Maybe 
subsequent generations may not use rhino horn, but by then the rhinos may be 
gone anyway...

Hi Mike,

I'm not sure about making better local opportunities as a conservation strategy 
in this case. It's my understanding that gorilla poaching is driven by the sale 
of their parts in cities. It's difficult to imagine these enterprises unable to 
find a labor supply. Perhaps the stick would work better than the carrot. Some 
bioeconomic models of illegal hunting suggest it is more effective to penalize 
the market at point of sale rather than the poacher. I'm sure Uganda takes 
gorilla poaching very seriously already since they are a national treasure and 
source of tourism revenue. But what can be done about this?  Is there a role 
for conservation science?

Re: [ECOLOG-L] Ride the Train to ESA 2012 in Portland, OR!

2012-05-17 Thread Amartya Saha

Hello Jorge,
riding a train cross-country is extremely enjoyable, affords time for  
oneself and is also a great gesture.


But at the same time, unfortunately it is time consuming (5 days from  
Miami to Portland one way, difficult to take that much time off for,  
especially for those with families) as well as expensive ($638 one way  
seating only, unless one books 3 months in advance to get 50% off).  
Poor Amtrak.


As regards reducing the environmental footprint of a conference, that  
could happen if conferences got web-based, instead of one centralized  
place. There could be local conferences happening over the same period  
in major cities, linked by either real-time video, or archived videos  
of talks. There can be an online directory of posters, which people  
can browse at will, and contact authors by email (skype follow ups,  
whatever they organize personally).
This would certainly reduce the amount of travel, as well as enable  
far greater participation (way more global.. for instance a student in  
Lagos or Lima or Kolkata can access the portal).


I'm sure that is the direction as real-time streaming gets cheaper and  
more widespread. There would be increased energy costs in streaming  
and data warehousing, but that would be a blip in a world already  
bursting with online videos, etc.


Any discussion on this ?

Re: [ECOLOG-L] Invasion, or progression?

2012-04-24 Thread Amartya Saha
Hi Steve and Ling, another example of a native becoming invasive is cattail 
(typha) in the phosphorus oligotrophic Florida Everglades. Usually present in 
low population densities, cattail populations take off with increased 
phosphorus concentrations in water and soil (usually anthropogenic). Yet 
another example is the spreading populations of Vouchesia divergens in the 
Pantanal that are associated with drier conditions over the past couple 
decades. 

A plant community is dynamic and responds to changes in both biotic and abiotic 
factors that affect ecosystem structure and function. Thus a species once 
present in small numbers can dominate the community for a while..
The other question, when does an invasive become native, goes back to how we 
define what is native, or for how long does a species have to be present in an 
ecosystem to get naturalized. For instance, cocos nucifera, the coconut palm 
ubiquitous to tropical and subtropical coasts all over the world.. It is still 
a matter of conjecture as to where coconuts palms originated. If they were 
dispersed by ocean currents, then I suppose they would be considered native 
wherever they occur. If man were the agent of dispersal, they would be exotics. 
If brought in by man thousands of years ago, they would be naturalized exotics. 
If they invaded and dominated upon arrival, they would be invasive exotics. An 
exotic or native can bide their time in low numbers, and with an environmental 
change, suddenly take off, thus earning the term invasive.

Interesting question, can a native become invasive? I would suggest that in 
some instances this is the case. For example, eastern redcedar in the Central 
Prairie is native, but has now become invasive in many locations. The main 
reason is the lack of fire that used to occur naturally prior to settlement by 
Europeans. 

For those who want to know more, we will be addressing this topic at the NAIPSC

has invaded wetlands. I suppose my question is how far do we go back to

because invasions biology is attacked politically on this front, so it's one to 
which professionals really must craft a coherent response in friendly

Another point to consider is the evolutionary history of native vs.
introduced (non-native) species in any particular system.  One of the reasons 
non-natives are of concern is that they do not share evolutionary history with 
the native community, and this contributes to the unpredictable biodiversity 
loss cited by other comments presented here.
 This can also be discussed in light of the homogenization of life on earth, 
because there are many species favored, facilitated, or directly cultivated by

 deceiving and incompatible with a methodological scientific approach to
 the analysis of our world. This has been true since Copernicus and
 Galileo until nowadays.
 Therefore, I do not know how one can sincerely teach science and

 contradiction."

Well, it may not be universally correct to say that religion is  
incompatible with scientific belief. For instance, conservation of  
ecosystems and ecosystem services have played a central role in  
eastern religions. In India, the origins of the Holy Cow arose largely  
because of sustainability concerns of supporting a large human  
population on the subcontinent. In the Western Ghats and the eastern  
Himalayas in India, sacred forests are often the only patches of  
relatively undisturbed forest remaining. I have done paired watershed  
studies in the Western Ghats hills and seen dramatic differences in  
streamflow and aquatic biodiversity between undisturbed valleys with  
sacred forests and valleys with degraded forests. A riparian tree,  
Terminalia Arjuna has ben historically considered holy in central  
India, so that people do not cut it down. I won't be surprised if such  
pro-conservation perspectives have existed in most parts of the world.  
Indeed, scientific progress over the last couple centuries has served  
to increase natural resource extraction and overconsumption globally,  
even though life expectancy has increased and societies are shedding  
many harmful taboos.


As regards the original thread of what we can do, it strikes me that a  
critical task is education and outreach by scientists to k12 schools  
and community organizations. Perhaps universities can include that in  
an academic's job duties, so as to allow time for a scientist (who is  
normally extremely busy) to connect with the public, design small  
projects in schools and co-lead then with school teachers.

In the case of the mainstream religions, the issues already appear when

the embarrassment of being proved wrong by science and common knowledge.
The problems are as much the "holy" texts, as the process of belief, as
the institution. All of them are incompatible with the scientific method.


It is true that many wars or hostilities have been based on religious

First, they are antagonistic for the reasons that I gave in all my

Second, it is not because they were born from the same curiosity and

Interesting points.
 
At the same time alien/introduced/invasivespecies that truly alter an

am not aware of any examples outside of, maybe, humans.
 
There exists serious economics benefits to many in the realm of 'alien species 
battles'.  The lionfish, Pterois volitans and, possibly, P. miles, are a good 
example.  Even quasi-scientific articles continue to villify them, describing 
their voracious appetites and ability to out-compete all native species.  Yet 
stomach anlysis fails to support those contentions.  There is no question that 
it has successfully established itself, do date from New Hampshire to Colombia, 
throughout the Caribbean and it would be a miracle if it is eradicated.  But 
significant ecological perturbation has yet to be proven.  That does not stop 
dive shops, REEF, and a plethora of other organizations from putting together 
derbies, round-ups, and the like geared to the illusion that this is the way to 
eradicate the pest.  It should be noted that all that organize such events 
charge for it, thus deriving a benefit from the lionfish.  In areas where scuba 
diving was waning,
 the arrival of the lionfish has been a boost.
 
Thus, despite the generally accepted view that eradication is near impossible, 
it is turned into a cash cow - cash fish.
 
Indeed a fresh assessment of this issue should be welcome as if it is accepted 
that the 'Earth' is changing, why is it blieved the biota of the various 
localities will remain unchanged.  International trade, globailzation, and like 
activities are conducive to such introductions and it would be through such new 
thinking that the issue would receive a fresh understanding.

This seems to me more like a philosphical issue, rather than a scientific one. 
there are obviously several mechanisms that allow plants to actively "seek" 
water. However, unlike the mechanisms that allow an animal to seek water, such 
as detecting moisture in the wind using smell, they do not require a conscious 
desicion, i.e., the animal may decide to follow or not follow the scent, the 
plant does not have a choice. So the question is whether "seeking" requires a 
conscious desicion to be made by the individual. It could also be argued to 
what extent the desicions made by animals, such as humans, are conscious versus 
subconious and whether a subconcious desicion satisfies the definition of 
"seeking".

Subject: Re: [ECOLOG-L] Communication Science to Public Plant Roots

Well, I can't say what the narrator was basing his/her statement upon, but
it can be justified.  Roots are, for the most part, programmed to grow
downward (positive geotropism), and in many if not most soil environments,
water is more abundant at lower levels.  Thus, growing downward means
growing toward water.  (One situation where this doesn't hold true is right
after a rain, when the upper level of soil may be wetter then a lower
level.)

Additionally, roots (like all protoplasm-based structures) need water to
grow.  Thus, roots that are tentatively entering a wet zone (assuming it's
not too wet) will grow faster than roots entering a dry zone, thus setting
up a positive feed-back loop regulating root growth, which obviously has a
genetic component.

Finally, you may consider differential mortality of root cells in wet verus
dry soil regions as also being a genetic program that causes the root SYSTEM
to grow toward water.

I think this is enough to justify the statement.  Of course, the statement
is a bit misleading in that it may call up the image of a little root tip
sniffing first in one direction, and then in another, and finally saying,
"Ah, the water's over there; I'd better grow in that direction."  But this
sort of imagery often colors our understanding of mechanistic processes in
biology, even for scientists (for me, at least).

Gladys I. Cassab (2005) Hydrotropism:Root Growth Responses to Water.  
Trends in Plant Science

On often comes across much denser root growth out to one side of a  
plant, if there is much more moisture in one side relative to the  
other side, like a dripping tap.


There are many more studies looking at root distribution between trees  
and shrubs/ grasses in savannahs, that takk about lateral spread for  
sparse water and nutrients.


Mycorrhizal associations, as I have read, are very important for  
nutrient aquisition, especially immobile Phosphorus. I wonder how  
important would they be as a water source; am not aware of any study  
that attempts to quantify how much of a tree's water budget would come  
from mycorrhizae as opposed to direct root uptake - interesting idea  
that ! I have heard about mile long mycorrhizal strands in the Sahara  
desert, where one expects that mycorrhizae can take advantage of dew  
at dawn better than roots can, owing to their finer thickness, net  
like structure and greater surface area.

Quoting Tom Horton :


I will suggest that many plants partner with mycorrhizal fungi for
water and mineral acquisition. So the fungi access water and deliver it
via the hyphae directly to the plant hosts. Estimates vary, but about
80% of the world's plant species are mycorrhizal and consideration of
root physiology and soil interactions in the absence of the mycorrhizal
partners is probably misleading.

Quoting Jeremy Fox :


The peer review system is breaking down and will soon be in crisis:
increasing numbers of submitted manuscripts mean that demand for reviews is
outstripping supply. This is a classic "tragedy of the commons," in which
individuals have every incentive to exploit the "reviewer commons" by
submitting manuscripts, but little or no incentive to contribute reviews.
The result is a system increasingly dominated by "cheats" (individuals who
submit papers without doing proportionate reviewing), with increasingly
random and potentially biased results as more and more manuscripts are
rejected without external review.

In the latest issue of the ESA Bulletin (July 2010, v. 91, p. 325), Owen
Petchey and I propose a classic solution to this classic tragedy:
privatizing the commons. Specifically, we propose that instead of being free
to exploit the reviewer commons at will, authors should have to "pay" for
their submissions using a novel "currency" called PubCreds, earned by
performing reviews. We discuss how this simple, powerful idea could be
implemented in practice, and describe its advantages over previously
proposed solutions.

alternative, implemented. We have set up a petition at

support this idea, at least enough to want to see it further discussed. The

Five giant non-native snake species would pose high risks to the health of
ecosystems in the United States should they become established here,
according to a U.S. Geological Survey (USGS) report released today.

The USGS report details the risks of nine non-native boa, anaconda and
python species that are invasive or potentially invasive in the United
States. Because all nine species share characteristics associated with
greater risks, none was found to be a low ecological risk. Two of these
species are documented as reproducing in the wild in South Florida, with
population estimates for Burmese pythons in the tens of thousands.

Based on the biology and known natural history of the giant constrictors,
individuals of some species may also pose a small risk to people, although
most snakes would not be large enough to consider a person as suitable prey.
Mature individuals of the largest species—Burmese, reticulated, and northern
and southern African pythons—have been documented as attacking and killing
people in the wild in their native range, though such unprovoked attacks
appear to be quite rare, the report authors wrote. The snake most associated
with unprovoked human fatalities in the wild is the reticulated python. The
situation with human risk is similar to that experienced with alligators:
attacks in the wild are improbable but possible.

“This report clearly reveals that these giant snakes threaten to destabilize
some of our most precious ecosystems and parks, primarily through predation
on vulnerable native species,” said Dr. Robert Reed, a coauthor of the
report and a USGS invasive species scientist and herpetologist.

High-risk species—Burmese pythons, northern and southern African pythons,
boa constrictors and yellow anacondas—put larger portions of the U.S.
mainland at risk, constitute a greater ecological threat, or are more common
in trade and commerce. Medium-risk species—reticulated python,
Deschauensee’s anaconda, green anaconda and Beni anaconda—constitute lesser
threats in these areas, but still are potentially serious threats.

The USGS scientists who authored the report emphasized that native U.S.
birds, mammals, and reptiles in areas of potential invasion have never had
to deal with huge predatory snakes before—individuals of the largest three
species reach lengths of more than 20 feet and upwards of 200 pounds. The
reticulated python is the world’s longest snake, and the green anaconda is
the heaviest snake. Both species have been found in the wild in South
Florida, although breeding populations are not yet confirmed for either.

Breeding populations have been confirmed in South Florida for Burmese
pythons and the boa constrictor, and there is strong evidence that the
northern African python may have a breeding population in the wild as well.

“Compounding their risk to native species and ecosystems is that these
snakes mature early, produce large numbers of offspring, travel long
distances, and have broad diets that allow them to eat most native birds and
mammals,” said Dr. Gordon Rodda, a USGS scientist at the Fort Collins
Science Center and the other coauthor of the report.

In addition, he said, most of these snakes can inhabit a variety of habitats
and are quite tolerant of urban or suburban areas. Boa constrictors and
northern African pythons, for example, already live wild in the Miami
metropolitan area.

The report notes that there are no control tools yet that seem adequate for
eradicating an established population of giant snakes once they have spread
over a large area. Making the task of eradication more difficult is that in
the wild these snakes are extremely difficult to find since their
camouflaged coloration enables them to blend in well with their surroundings.

“We have a cautionary tale with the American island of Guam and the brown
treesnake,” said Reed. “Within 40 years of its arrival, th

Re: [ECOLOG-L] Ecohydrology Ratio of water to biomass Re: [ECOLOG-L] Postdoc: Ecohydrology/Plant Water Use, Duke University

2009-08-20 Thread Amartya Saha
hello Wayne, this is a very interesting question - if i understand you  
correctly, you are enquiring into how much water an individual of a  
species has taken up in its lifetime (to date) and connecting this  
with the total biomass produced to date (including shedded leaves,  
sloughed off roots, fruits, etc).


Now this total biomass over lifetime estimate would be available only  
in a greenhouse setting.  So alternatively you seek to get an estimate  
of total water uptaken and relate that to dry biomass at an instant of  
time.


I imagine there would be a huge amount of intraspecific variation  
caused by the specific conditions of water and nutrients an individual  
may have encountered in its lifetime to date.


In addition, there would also be interspecific variation ( as you  
allude to while comparing cactus and corn), especially when comparing  
species in arid and moist environments, with a larger water to biomass  
ratio expected for aridland vegetation as compared to vegetation  
growing in humid climes.


this could be tied in with species level Water Use Efficiency, I guess.

Quoting Wayne Tyson :


Ecolog:

It depends upon how one defines "water use efficiency," I suppose, but
not in the "production" sense as commonly conceived in the in the case
of agriculture and horticulture, but I wouldn't want to rule those out
either. To put it in contrast, agriculture/horticulture tends to be
more concerned with the amount of production or keeping a plant in a
state of luxury consumption most of the time, whereas "wild"
self-sufficient vegetation is more "concerned" with survival and
reproduction.

To cite a couple of practical phenomena, consider "cattails" (Typha
sp.) growing at the edge of a body of water, and draw a graph, say, at
the top of the plants to indicate one rough measure of biomass; as
water intake declines, biomass declines (setting aside other
effects--O2, pH, nutrients etc.) for the moment). In a cultivated
field, one can observe similar variations due to water intake.

I hope this helps; I apologize for not being clearer--please continue
to ask for further clarification as necessary.

age would have a high ratio of total water CONTENT to dry biomass, but its
ratio of the total amount of water required to produce a given unit of dry

Re: [ECOLOG-L] Recycling and the poor who do it

2009-08-06 Thread Amartya Saha

Thank you, Bill, for these stories.

Recycling is a private enterprise in india, run nationwide by  
thousands of small merchants who buy paper, glass, cans and hard  
plastics from an army of ragpickers hailing from the lowest castes. As  
the article mentions, these ragpickers, unfortunately, get paid barely  
enough for their next meal, surviving hand to mouth, living on the  
streets, yet providing a vital service to the cities, the environment  
and the economy. The article mentions a very practical idea for  
governments to bolster this recycling sector by supporting the  
ragpickers and ensuring that they are not at the mercy of global scrap  
prices.


The latter requires international cooperation, whereby reuse and  
recycling are given priority over mining/drilling/logging for  
production of virgin resources. Unfortunately, doing the latter in the  
third world is often more 'economical', since multinationals and  
certain manufacturing economies collude with corrupt third world  
governments into opening up their forests, in the name of  
'development', that is cheaper than recycling costs in the first world  
(primarily high labor costs).


Achieving a higher degree of recycling worldwide would require a  
combination of environmental disposal fees built into product prices,  
like a tax,  incentives for consumers to recycle, such as beer bottle  
refunds in many american states, government regulations to prevent  
collapsing scrap market prices and formalization of the developing  
world recycling sector.


While many ECOLOG_L folks might be more aware of dung beetles, most  
people in India and Brazil are JUST AS unaware of the ecosystem and  
economic services provided by the children of the damned.

Quoting William Silvert :


When I saw this in yesterday's paper I wondered about posting it to the
list, since there is so much discussion about recycling. Then on the TV this
morning there was a story about waste collectors in Cairo who are being
devastated by government policy - they are members of the Christian minority
who feed pigs on waste and sell them as a large part of their income, and
the government had all the pigs killed to halt swine flu even though there
was no evidence of infection in Egyptian pigs. As a result, the edible
garbage is piling up in the streets and the vermin population is exploding.
And the children of the waste collectors are suffering from malnutrition
because the poverty of their families has gotten much worse.

The two stories point up a little-known aspect of recycling, that it is
largely the domain of the poorest and most despised members of society who
are at the mercy of forces beyond their control and subject to arbitrary
from government and from economic pressures. Yet they form an essential
component of the human ecosystem and play a vital role in recycling and thus
in resource management.

I suspect that the members of this list know more about dung beetles and
other detritivores than about the humans who have the same function. In Addo
Elephant Park there are signs all over the place warning drivers to slow
down and look out for dung beetles, but I have never seen any evidence of
similar concern for people who struggle to keep our cities clean. Maybe they
deserve some thought and attention.

A Scrap of Decency
By BHARATI CHATURVEDI
Delhi, India

AMONG those suffering from the global recession are millions of workers who
are not even included in the official statistics: urban recyclers - the
trash pickers, sorters, traders and reprocessors who extricate paper,
cardboard and plastics from garbage heaps and prepare them for reuse. Their
work is both unrecorded and largely unrecognized, even though in some parts
of the world they handle as much as 20 percent of all waste.

The world's 15 million informal recyclers clean up cities, prevent some
trash from ending in landfills, and even reduce climate change by saving
energy on waste disposal techniques like incineration.

They also recycle waste much more cheaply and efficiently than governments
or corporations can, and in many cities in the developing world, they
provide the only recycling services.

But as housing values and the cost of oil have fallen worldwide, so too has
the price of scrap metal, paper and plastic. From India to Brazil to the
Philippines, recyclers are experiencing a precipitous drop in income. Trash
pickers and scrap dealers in Minas Gerais State in Brazil, for example, saw
a decline of as much as 80 percent in the price of old magazines and 81
percent for newspapers, and a 77 percent drop in the price of cardboard from
October 2007 to last December.

Quoting Kelly Stettner :

Wayne: I love your enthusiasm and support for the "sparks" that   
ignite conversation and imagination!

 
Joe: Thank you for your "humble opinion," you invite me to clarify   
and ask more questions.  You note two points about economic growth:

 
1. "Economic growth", as commonly used, means that every year the   
human species creates more "economic activity" than the year before   
(fueled by growth in both population and per-capita consumption).


2. "Economic activity" inevitably involves consumption of resources,  
 so that means every year we convert more land to human use,  
generate  more electricity, cut more trees, mine more minerals and  
fuels,  manufacture more goods, produce more pollution, catch more  
fish,  etc.  So clearly there has to be a limit at some point.

 
Joe, Since I'm not an economist, I must ask questions in order to   
understand.  I see what you're saying in both of the above points;   
unlimited "taking" is short-sighted and self-defeating.  However,   
can the growth and activity you describe not be coupled with   
activities that replenish what we consume?  We cut trees and mine   
the earth ~ but we can also replant and learn ways to harness the   
energy we need from a variety of resources.  I know that much of our  
 technology seemed like science fiction just ten or twenty years   
ago.  iPhones, blackberries, laptops ~ even digital watches were   
fantasy before they became reality.  Is there reason to believe we   
can't figure out how to replenish the resources we use, use them   
more efficiently, engage in utilizing other resources we hadn't   
tried before (Sea-floor vents?  Algae?  Kudzu or Japanese knotweed?   
 Something on Mars on the moon?), and find ways to lessen our impact  
 on the planet?  Green roofs,
 companion gardening, rain barrels, etc are all low-tech, old ideas   
that could be just the beginning ~ and could also fuel the economic   
growth of our society.  Businesses are cropping up all over the   
place to explore these ideas.

 
I also see economic growth in terms of those nations with big   
problems: I'm thinking about improving pollution and sanitation and   
waste issues in places like Africa and India and China.    
Environmental degradation isn't just a Western problem; I think it's  
 even more critical of an issue in less-developed areas of the   
world.  Change in those places will take more than a few years,   
it'll take a change in government before any real environmental   
issues are recognized and addressed.  The issues of population,   
sanitation, poverty and pollution in those areas of the world are   
far more complex than I can understand at this point in my life, but  
 I feel strongly that the developed nations need to recognize that   
Third World pollution & waste are a huge "elephant in the room."

Re: [ECOLOG-L] Re ESA Position Statement

2009-07-27 Thread Amartya Saha

Dear Nadine/ESA,

thank you for your post. I was quite puzzled to read

"We all agreed that an ESA statement

needed to highlight the conflict between two fundamental truths:

1. Humans in the developing world have a moral right to try to 
improve their well being.
2. There is a finite capacity of the planet to support humans and 
increasing resource consumption and waste production will degrade 
the planetary carrying capacity."


There is no mention of the developed world vis a vis truth no.2

Then, I am doubtful that no.1 can be considered a "truth". First world  
models of development are in most cases inapplicable to the third  
world. For instance, mechanized agriculture makes sense in the  
sparsely populated wide open spaces of the new world, while this would  
render millions of small farmers landless in the third world. Prior  
"development" projects ( whether agribusiness or large scale  
hydroelectric power) have usually benefitted a few, while  
marginalizing millions.
It is the few who now clamor loudest for SUVs, hybrid cars and other  
material trappings of the west. While hybrid cars are better than  
SUVs, a mass transit system is far greener on a per capita basis.  
Improving living  conditions in developing countries requires  
protecting land, water and  air resources, providing education and  
primary healthcare to all, and not just indiscriminately manufacturing  
more hybrid cars for the haves.


Lastly, it should not be the role of ESA to offer a compromise; that is the
role of the government. ESA is the premier source for information on
ecosystem impacts.

Quoting Nadine Lymn :


Dear All:

In a recent correspondence with an individual concerned about ESA's   
  position statement, ESA Board Member Josh Schimel points out that   
  the Governing Board took very seriously its task of representing
 10,000 ecologists and carefully deliberated in issuing the ESA 
statement.  With his permission, I post Josh's correspondence below.


Nadine Lymn
ESA Director of Public Affairs



The ears were not deaf. On the contrary, they were wide open. We 
heard and agreed with many of the fundamental points Brian, you and   
  others had been making. But those weren't the only messages coming  
   in and we had to balance those different perspectives. The 
discussion at the Governing Board meeting was extended, thoughtful,   
  and analytical. There are a number of extraordinarily insightful   
and   concerned people on the board. We all agreed that an ESA   
statement   needed to highlight the conflict between two fundamental  
 truths:


1. Humans in the developing world have a moral right to try to 
improve their well being.
2. There is a finite capacity of the planet to support humans and 
increasing resource consumption and waste production will degrade 
the planetary carrying capacity.


Thus, we felt that the statement had to argue that we needed to 
balance those conflicting truths. As ecologists, we can and should
 focus on the second--managing the carrying capacity, but we can't
 tell poor people that they may not improve their living conditions.  
   There are ethical boundaries just as there are ecological 
boundaries. We didn't feel that we could cross one while arguing 
that we must not cross the other. So, the key front section starts
 by highlighting that conflict, and personally I think it does it  
well:

The Sustainability of Economic Growth
At present, economic growth is a double-edged sword: Although it 
enhances the standards of living in the short-term, it can degrade
 the ecological infrastructure needed to sustain long-term welfare.   
  This dichotomy may be humanity's central challenge in the 21st 
century-sustaining living standards and spreading the benefits of 
economic development to the large fraction of humanity still mired
 in poverty, while preserving the ecological life-support system on   
  which future welfare depends.

The whole document is a major redraft from the initial one, which 
many were unhappy with because a) it focused too much on the right
 to develop, b) didn't emphasize the carrying capacity issues 
adequately, and c) read too economic-speak rather than 
ecological-speak. I.e. we were concerned about the same core issues   
  you and others were highlighting, partly in response to your  
input.The current document focuses on the risks to ecological  
systems  (and   thus the long-term well being of humanity) and the  
need to  manage   them rationally. Those are appropriate messages  
for  ecologists to   make.


However, and this may be where the apparent disagreements arise:

[ECOLOG-L] The mirage - ECONOMIC growth, population and a couple of stories

2008-12-20 Thread Amartya Saha

However, to quote Sarah "It is all a

It is something we made up. It is not real."


I think economics is, unfortunately, VERY real. Conservation of  
ecosystems, national parks, protected areas and the exploitation of  
natural resources are all directly linked with human needs, both basic  
and luxury. In the end, humans are part of the world too, and their  
actions directly impact all other forms of life.
Its time that a course embracing both perspectives are taught to  
school children right from first grade, so that they understand what  
are the ecological costs of say, a plastic water bottle, or a can of  
tuna, or transporting organic apples from washington to florida, or  
the costs of airconditioning or needless packaging, or what happens to  
the batteries and computers when we junk them. And then raise  
awareness of ecosystems, with case studies of community-based  
conservation in other countries. Unless most people are aware of such  
effects, we'll be on the same consumption-based trajectory we are  
currently on, never mind all the carbon neutral rock concerts and even  
recycling.

Re: [ECOLOG-L] Insecticide Decimates Tadpole Populations Through the Food Chain

2008-10-03 Thread Amartya Saha

Hi Paul,

what the study showed is that sublethal doses of malathion can 
negatively affect leopard frog tadpoles by affecting their food chain. 
Sublethal to leopard frogs, but lethal to zooplankton.  Its a matter of 
insecticide/weedicide CONCENTRATIONS. Yes, it can be that in the field, 
such concentrations are often lower than in the U Pitt tank study. 
However there can be (and will be) instances where this concentration 
may be reached or even exceeded, depending on topography/drainage, 
rainfall and a host of other factors. Even with low concentrations, 
there can be accumulations over time, which can then lead to a lag time 
between application and observable effects. By then the momentum of 
negative effects can be too high, and too late to reverse conditions, so 
that the hundreds of leopard frogs that were flushed by a t-storm in MN 
may not happen a few (?) decades from today...


The message I got from this study is that concentrations lower than lab 
determined lethal doses can harm the organism in question, by also 
harming the ecosystem - kind of an urging for ecotoxicology to put more 
emphasis on ecosystems and not just organisms in isolation.

that cover ~70% of the land mass of southern Minnesota and Iowa:

Re: [ECOLOG-L] Ecosystems and faux ecosystems Re: [ECOLOG-L] Wetland creation

2008-06-12 Thread Amartya Saha
Hi Bill, the answer might depend on the spatial extent and intensity of 
the fire ( assuming that the fire happens in a fireprone ecosystem, 
where fires have been natural occurances as well), if there has been 
active fire suppresion in the area allowing fuel buildup, and so on. If 
an arson fire got out of control and burned a whole ecological reserve 
down, including islands of vegetation that are normally safe from 
groundlevel fires, then it would be destruction. Whether that 
destruction is reversible would depend upon the success of species 
coming in from the surroundings to recolonize.
Now, if this supposedly arson fire were actually caused by lightening, 
and if the area has seen fire suppresion for decades, the fuel buildup 
could cause a much hotter fire than normally would be the case. Then it 
would also be seen as destruction ( the management leading to fire 
suppresion ). If the area has had no intervention in the form of fire 
suppresion or hydrological modifications leading to drier conditions, 
then it would be a natural process...


To Jer's comment
"Find out which ecosystem we have degraded/destroyed most over the years 
and you will probably find the ecosystem most often "restored"."


Its a bit hard to do that, since barring a few isolated spots on the 
globe, almost all ecosystems have been degraded/destroyed, and not much 
restored.


And to the original idea of thread,  i do not know the extent of 
artificial wetlands, but like Wayne, I'd like to point out that too 
often the general public ( developers, polititians and the like ) glibly 
equate a created wetland with one that has been in place for centuries 
or even longer. Rarely can an artificial wetland approach the species 
diversity and resilience of a natural wetland (in the same bioregion) in 
the early ( read that as 20 years, my guess), and the rate at which 
diversity builds up would depend on the existence and proximity of other 
wetlands for colonizing species to arrive, succession to take place, 
hydrological inputs and outputs that maintain the wetland ( as opposed 
to succeeding to a bog and then land ), and so on...there lies the most 
severe criticism of the "no net loss" policy of wetland mitigation.
I"m not against artificial wetlands, indeed they have tremendous use in 
wastewater treatment and habitat creation, but quite often the language 
equating different forms of wetlands is diffuse.

To add to the thread, I suppose these dams are no more than 150 years 
old at most ? So the wetlands created by placing the dam are not very 
old, thereby quite possibly not as species-rich as a natural wetland
Furthermore, the original (pre-dam) ecosystem being a running water 
system, its restoration can have greater ecological value, since there 
are few locations on the landscape where streams can naturally exist., 
ie, basically along local topographic lows. There is also the river 
continuum concept whereby removal of artificial barriers to water flow 
can have an impact far beyond the immediate stream reach.


However its possible that these particular artificial wetlands could be 
important sites of refuge for wetland spp that managed to arrive there 
-- as Sharif mentions, it would be good to actually examine the wetlands 
in question, and then decide. Generally speaking, stream restoration 
could provide more ecological diversity, as its technically easier to 
create a wetland elsewhere (in theory at least), but the benefits and 
costs could vary from case to case.

You could consider the quantity and diversity of the species that benefit from each habitat type. You could even look at ecological services being provided by the wetlands versus what will be gained by breaching the dam.  I hope that helps you get at the essence of the argument.

Hi Jane,
Robert's point was about the resources taken to manufacture a new car, 
hybrid or whatever.. all the metal, glass, plastics, chemicals etc, 
mining those, energy costs to manufacture them, pollution costs to the

hybrid, one has to add all the above costs to the benefits of lower 
emissions per mile.  Its not just C emissions that accompany the 
manufacture of a car, there is a bunch of other externalities if one 
were to track.
Of course, given the necessity of driving for most (In the US), one 
can't run an old car forever, unless one is a mechanic, understanding 
and taking care of every strut, wire and screw. Maybe the breakeven in 
terms of environmental costs of continuing with the old car vs. a hybrid 
may happen in 10 years, I do not know, and its very difficult to put $ 
costs anyway to damage to habitat done by resource extraction

Re: ecological "footprint", 3rd world vs. 1st world

2007-12-05 Thread Amartya Saha
Hi Kelly, 

I agree that the 1st world has taken the lead in designing environmental regs
for land, water and air quality protection, many of which serve as models for
'developing' nations. 

However, the efficacy and implementation of these regulations in the FIRST
world
 is another matter.  For instance, we have yet to be able to design efficient
riparian buffers for controlling nonpoint pollution in streams. A lot of the
regulations are watered down by compromise to the point of being meaningless,
such as the 'no net loss' policy for wetland mitigation, that equates a natural
wetland with its centuries of community development with one that is created
with a bentonite liner. There are numerous such examples we all know. 

And then practically the entire manufacturing sector and toxic waste disposal
has been *conveniently* shipped to the third world. 

"We are cutting down on

> bank care."

I have to absolutely disagree with this. The hypoxic zone in the Gulf of Mexico
is growing, precisely due to fertilizer runoff throughout the Miss. watershed.
The everglades is undergoing plant community changes due to fertilizer runoff
from Big Sugar. 
Driveway car washing -- the third world does not even know what this is. Cars
there are washed with a bucket and a rag. 
Stream bank care -- if this was happening in any significant scale in the 1st
world, freshwater aquatic biodiversity would not be declining. Clean water is
admirable, and a first step, but it is not enough. National parks need to
include the river continuum concept. and so on.

Having said all this, I have also pointed out in an earlier email, that from a
planet Earth perspective, there are TWIN problems, of not just overconsumption
in the first world, but also population in the third world along with rising
urban consumption there. I am not just pointing fingers at the
first world. The mess is increasing everywhere. And as long as the defense
budget far outweighs the combined budget for environmental management,
education, healthcare and so on, there is not much hope of arresting the
dialectical fate of any civilization or dominant species.

Re: N/P Ratios and Algal Growth

2007-12-03 Thread Amartya Saha
Hi Todd,
there is a classic paper by GW Schindler in the 70s about P limitation in lakes,
and if i remember right, there were some N:P ratios alluded to there. IN another
book by Wetzel, there were N:P ratios of 23 and above.. this is for the water
and not any organism tissue.
I have also heard that usually marine systems are N limited and not P limited,
which would mean that freshwaters (often P limited) would have ratios higher
than Redfield's.

After people moved out of caves and trees, EVERY single house that man has
built
 anywhere in the world HAS displaced something-- forest, natural grassland,
desert sand habitat, whatever. The point is that a third world shanty has a
much lower PER CAPITA space usage than say houses in American (or Brazilian)
suburbs.
And they are not heated or centrally airconditioned, to the point where folks
wear shorts while its -30 degrees outside, or folks cuddle up in bed with
blankets with the AC full blast while its actually nice and cool outside. Not
that I am advocating favelas, but Cara is right that the per capita footprint
in the third world is a lot less.

I'd like to add that this is especially true of the old world.
which has had a high population for the last several millenia, unlike latin
america which has been *colonized* and "settled" only in the last 400 years (
from a land transformation point of view).

Twin problems face the earth --- the third world's high population and the
first
world's high level of consumption. None of these have easy fixes. 

Population control requires widespread education along with economic
opportunities, and even then a huge population like India or China has a
momentum associated with it. 

The first world's high consumption. Again this is not easy to fix, unless cities
are radically redesigned and public mass transit improved, gasolene taxed,
people give up unsustainable practices of central AC/heating, lawns, the whole
consumer culture, and pretty much harken back to the pre industrial age.
Some folks advocate alternative energy use ( like biofuels ) but lets not kid
ourselves, there has to be a REDUCTION of resource use. not substitution. 

Can or will this be done ? Unless humanity as a whole gets more savvy, and maybe
they will in a generation or two, there is not much hope of moving away from a
mad max scenario.

Where did this come from ? Firstly I doubt that levels have come to
pre-industrial era, much less the pre-civilization epoch. Secondly, the
majority of the products in first world supermarkets ( especially the US ) come
from the third world, and this has shifted the production of effluent and gases
to the latter. As long as per capita consumption remains high, and energy/waste
handling tech not significantly different from present day, how can there be any
 reduction in global emissions ? Thirdly, public transit in the US keeps getting
slashed, forcing people to drive (except the NE corridor and certain small
communities ). And so on and on and on...

We in the first world have access to lifeboats ( except inner cities and
hillbillies). Most of the third world won't. When water shortage results from
frequent droughts, flow modifications, deforested watersheds, pollution,
withdrawals, whaterer, the urban folk will get their bottled water from
elsewhere, no worries for at least a decade or two. The rural poor will parch,
dehydrate and return to the soil. 
The same applies to other resources. Mad Max was kinda ahead in this
vision...the collapse of civilization followed by energy wars.

And then where or for how long can our lifeboats sustain us ? Questions we'd

Re: Consumer Choice & the Environment

2007-03-20 Thread Amartya Saha
Its great if our own decisions significantly lower the net environmental
impact.
However just choosing what car we drive, wearing sweatshirts at home in the
winter and switching to a diet based on grains and low on meat/fish and
veggies/fruits (growing lettuce in Calif is not exactly environmentaly
friendly), while commendable, would not seriously reduce the impact we have. 

Today we have a lot more appliances in our houses and we use a lot more
resources than before the industrial revolution, or even 100 or 50 years ago.
Thats true even in third world cities and towns. We have fridges and ovens, TVs
and electronics, motorcycles and cars, books and papers, food related
packaging, and now computers and mobile phones, just to name a few. 

Each fridge has exacted an environmental cost ( mining for metal, energy for
manufacture and transport, pollution from manufacture, energy for operation and
final disposal of chemicals). Such is more or less true for every item. Ideally
if we reuse and recycle, and get alternate ecofriendly energy, and implement
measures to curb pollution perhaps the cost would not be as high as it really
is. I can't help wondering that our use of resources just keeps increasing, not
only on a per capita basis but also spreading throughout the rural tropics. It
requires a months stay in a third world village to see how many thousand times
more resources we urban folk consume. As I am doing here sitting in this
freezing airconditioned windowless room in lovely miami typing this email. 

Even if we all drive hybrid cars, or that run on biofuel, we know that a better
alternative is rail based mass transit. However, the fact that we are all much
morte mobile than 100 years ago ( including jet travel ) means that our impact
grows more and more. I don't intend to sound pessimistic, just that the field
of
matural resource economics hasn't yet matured enough to quantify impacts. And we
cannot go back to the pre-industrial age.

Re: Why is the public not as concerned?

2006-11-30 Thread Amartya Saha
Thanks for sending the link to the survey. I was quite surprised that the survey
had no questions on whether one can reduce one's own ecological footprint. It is
easy to blame someone else, be it president Bush or american business. But one
appears to forget that american business (or international) would grind to a
halt if consumers (we) did not buy their products. Or call out for a change.
Such as the tremendous amount of packaging in the food industry. 
Some other roles can be attributed to the government, such as creation of
functional mass transit systems. 
But the way the survey has been compiled, it appears to have entirely missed the
point as to how the public may be involved with the deteriorating environment.
Another flaw is that the survey fails to list some of the major issues of
environmental degradation. climate change is not the only one...

I agree that paraphrasing requires one to understand the material one
references, as well as express it more concisely ( in the interests of space
).

However, sometimes I have come across papers where the authors misinterpreted
the original results or ideas, and thereby this misinterpretation was carried
forward in their paraphrasing. This could be dangerous, especially if someone
else were to quote the misinterpretation.

Well this is a completely different issue, but about education in the Orient, I
don't know if its mostly memorizing. My undergraduate institute heavily
focussed on understanding basic principles and applying them. But again perhaps
thats a basic difference between engineering and biology.

Re: On Plagiarism

2006-10-04 Thread Amartya Saha
Hello all,
for quite some time i have had some confusion over quoting literature, and
perhaps this plagiarism thread could offer some ideas..

If one were to quote a paper, i have heard that one is NOT supposed to directly
lift a sentence or para or any parts thereof, even though the paper would be
quoted as a reference. Instead, one has to paraphrase the same in one's own
words.
Is this true ? If so, the logic fails me. How does it matter if one rephrases
the sentence, when the idea or result has been copied ( and referenced of
course ).

Thanks for any views
amartya

Re: Environmentalist definition? Re: env science programs

2006-05-23 Thread Amartya Saha
if related to conservation of ecosystems or biodiversity, environmental studies
programs ought to include a field component with grassroot NGOs, for students
to get an exposure to the realities of implementing conservation plans, and the
difficulties that do arise ( socioeconomic, cultural, political, financial).

Re: young scientists ability to publish compromised by page charges to authors

2005-12-21 Thread Amartya Saha
quoting Haas

A reasonable sum of money, as long as one is not in a developing country!

This raises a related issue, in that the mainstream international journals
include research from authors belonging to the developed world. Third
world researchers cannot afford to publish in these journals.
At the same time, obscure national journals from third world countries do
not feature in any database search as they may not be online. Quite often
it is difficult to even know of work being carried out in africa, asia and
latin america by local universities, if results were published in such
journals, which feature work of similar quality, but are unknown outside
their respective countries.

regards,
amartya
