[ECOLOG-L] Seeking Master's students in evolutionary ecology

2018-09-10 Thread Casey terHorst
The Eco-Evo Lab at California State University, Northridge invites
applications from undergraduates interested in pursuing a Master’s of
Science in Biology. In particular, we are seeking a M.S. student to work on
an NSF-funded project that examines the limits to strong effects of
evolution on contemporary ecological interactions. The student will help to
perform selection experiments on microcosms of protozoa consumers and their
bacterial prey that live inside of carnivorous pitcher plants. We are
examining how dispersal and gene flow may alter the evolution of protozoa
traits, and how these effects may cascade down to affect bacterial prey
diversity and community structure.



In general, research in our lab focuses on the interface between ecological
and evolutionary processes. We address how rapid evolution affects species
interactions, such as competition, predation, and mutualism. We are also
interested in how interactions among multiple species in natural
communities affect selection on traits and evolutionary trajectories.



Research in the lab encompasses a variety of study systems, including (1)
microbial communities of protists and bacteria that live inside carnivorous
pitcher plants, (2) symbiotic algae associated with coral reef organisms,
and (3) invasive plant species in California grasslands. Students are
encouraged to develop their own independent research projects. More
information is available at http://www.ecoevolab.com

The Eco-Evo lab is committed to fostering diversity in STEM. The student
will serve as a mentor and role model to undergraduate students that are
underrepresented in the field of ecology. CSUN is a Hispanic-Serving
Institution and an Asian-American-Pacific Islander-Serving Institution.
Women and members of underrepresented groups in ecology are especially
encouraged to apply.

Northridge is located in the San Fernando Valley in Los Angeles and
provides access to many different natural habitats. The location is within
a short commute of Santa Monica and Hollywood. The Biology program at CSUN
has a reputation of turning out excellent Master’s students who often
continue on to top-tier Ph.D. programs. CSUN was recently recognized by
*Nature* as one of the top 25 Rising Institutions for Research in North
America. Our interactive group combines faculty and students from the
Ecology & Evolution program, the Marine Biology program, and the
Microbiology program (http://www.csun.edu/science-mathematics/biology).

Previous research experience and a passion for answering scientific
questions will strengthen candidates’ applications. Interested students
should contact Casey terHorst (casey.terho...@csun.edu). In your email,
please describe your research interests, any previous research experience,
and your career goals. Include a CV or resume, if possible. Formal
applications to the department are due on February 15, 2019, but interested
students should contact me this Fall semester 2018.

[ECOLOG-L] Post-doc opportunity

2018-06-12 Thread Casey terHorst
Postdoctoral Research Associate in Microbial Ecology



The Eco-Evo Lab at California State University, Northridge is searching for
a post-doctoral researcher with skills in microbial ecology and interests
in community ecology, evolutionary ecology, or eco-evo feedbacks. The
position includes one year of funding, with potential for a second year
renewal, from a recent grant from the National Science Foundation. The
grant focuses on eco-evolutionary dynamics of protozoa and bacteria that
live inside carnivorous pitcher plants. The goal is to examine how
dispersal and genetic variation affect the relative effect of rapid
evolution and adaptation on ecological processes at the local scale.


The post-doc will be based in Casey terHorst’s lab at Cal State Northridge
in Los Angeles, CA, but will also work closely with Catalina
Cuellar-Gempeler at Humboldt State University and Tom Miller at Florida
State University. Candidates should have a Ph.D. or equivalent degree in
microbiology, ecology, evolution, or a related field. A successful
candidate must be able to work independently conducting experiments in both
lab and field settings. As the goal of the project is to examine how
protozoan (predator) evolution affects bacteria (prey) communities,
experience with aseptic techniques, molecular work, and bioinformatics
associated with the study of microbial communities is a plus. A record of
publication in this area of research will strengthen an application.


The Eco-Evo lab is committed to fostering diversity in STEM. The post-doc
will be expected to train, mentor, and serve as a role model to students
that are underrepresented in the field of ecology. CSUN is a
Hispanic-Serving Institution and an Asian-American-Pacific Islander-Serving
Institution. Women and members of underrepresented groups in ecology are
especially encouraged to apply. In addition, teaching opportunities may
also be available, but are not required.


Salary will be based on relevant experience. Interested candidates should
combine the following into a single pdf file: (1) a cover letter or short
(~1-2 pages) statement that describes your past and future research
interests, (2) a CV, (3) names and contact information for two potential
references. Submit the single pdf file via email to casey.terho...@csun.edu.
The ideal start date is January 2019, but this date is flexible. Initial
review of applications will begin on September 1, 2018. If you plan on
attending the Ecological Society of America meeting in New Orleans in
August, please contact Casey terHorst (casey.terho...@csun.edu) to try to

Re: [ECOLOG-L] Is Nature still a credible journal? Or is this the era of Kardasian science?

2015-04-15 Thread Casey terHorst
I don't think that these metrics should be used as a strict metric of
quality, but I don't think they can be dismissed either. The same media
that report on pop culture phenomena are also now used to report news from
the New York Times, Washington Post, and NPR.  Many people now use Twitter,
Reddit, Facebook, etc as their primary news source. If a Nature story makes
it into somebody's newsfeed and is actually read, I think that's a victory
for scientific literacy and public awareness of science. Aside from
communication with the general public, articles that were mentioned
frequently on Twitter were 11 times more likely to be cited than less
frequently mentioned articles (Eysenback 2011). While these metrics should
not be used as a proxy for the quality of a paper, they are likely a good
proxy for the broader impact of a paper.

 I  found a button to click called Article Metrics. Once clicked, I found
 it had three different metrics: 1. citations (zero as the article is brand
 new, but likely to be frequent in the future), an alimetric score
 apparently based on 9 tweets and one reddit, and a map of Twitter
 demographics (n = 5). The alimetric score  is calculated based on two
 main sources of online attention: social media and mainstream news media.

 Citations have their problems as a growing literature documents, but
 turning over judgement of quality to Twitter and Reddit suggests Nature is
 pandering to the standards society uses to judge the Kardasians, Miley
 Cyrus and Prince Harry in Las Vegas.

 And we want Congress and the public to take science seriously?

Apologies (kind of) for the mass email of self-promotion, but I'm
hoping to draw your attention to our new blog... The EcoEvoBlog, which
can be found at http://www.ecoevolab.org.


The first blog post is now up: Does the Squeaky Wheel Deserve the Grease?
http://www.ecoevolab.com/the-squeaky-wheel/

If you'd like to subscribe to the blog, there is also a box in which
you can enter your email on the right hand column.

The goal of the blog is to generate discussions, rather than provide
information, so we hope that you'll participate. This blog is
completely a selfish enterprise for us in the lab. Sometimes there are
issues that we just want to get off our chest, or other issues on
which we want to get feedback from others. Sometimes we want to talk
about a really cool paper we just read, or sometimes we want to tell
everybody about something new that we just learned. In other words,
there isn’t a clear goal for this blog, other than to share what’s
going on in the lab with the outside world. It is intended to be a
forum for discussion and we encourage you to engage with us and with
others in this forum. We hope that you find it useful.

Re: [ECOLOG-L] Expanding opportunity and innovation in science

2014-04-15 Thread Casey terHorst
I agree with some of these items and disagree with others, and don't
really want to argue those points in this forum.
My bigger concern is that if this list is meant to come from a group
of scientists, it should include scientific data, rather than opinion
and hostility. Are there data that tenure promotes exploitation and
laziness? I wouldn't be surprised if there were, but expressing this
point as personal experience, rather than a statistical trend, is no
different than saying that global warming is a farce because it is
cold where I am today. I am less sure that there are data to support
spousal hires as deplorable, without merit (surely there is SOME
merit, or nobody would do it), and reducing innovation and
productivity in science. In my experience, I have seen such hires
work out incredibly well for departments and for the field of science,
but again, that is just my experience and may or may not reflect a
broader trend.
Although there are some good points to be made here, expressing them
in such a way is unlikely to convince scientifically-minded people (I
wish this meant everybody).

 August 18, 2013 at 3:07pm
 Ideas for expanding opportunity and innovation in science careers - Version
 2 (REVISED)
 August 18, 2013 (3:00 PM EST)

 1) Elevating the White House Office of Science and Technology to
 cabinet-level.

 2) Expand the number and size of common core facilities for various research
 needs (analytical chemistry cores, sequencing cores, animal facility cores,
 etc.) and the number of stable career staff scientists positions
 ('permanent' with benefits) - but have them report not to an individual PI
 or faculty boss, but to the department as an institutional resource (not the
 property of an individual PI).

 3) Remove “trainee” (student and postdoc) salaries/stipends from research
 grants and make them all competitive fellowships, or (but this second one
 has some problems) give the money to institutions to pay student stipends
 with so that individual professors do not do the hiring or control the
 trainee’s employment/salary/benefits directly.

 4) Mandate that all institutions eligible for federal funding allow postdocs
 (and possibly graduate students) to be sole Principle Investigators on
 grants which they write if they choose.

 5) Invest in/create/fund a much wider variety of permanent/stable staff
 scientist career track positions at institutions geared toward Ph.D.'s -
 particularly for core research service facilities (which should be expanded
 greatly).

 6) Fund “Innovation Incubators” for postdocs (but with independent
 researcher titles) to work in common labspace, no offices, and using core
 facilities to pursue our research without a faculty boss. These researchers
 could do a lot with such limited resources, as long as we have independence.
 We could pursue our own funding and even stay in those positions if we don’t
 feel the need to seek higher titles – just remain productive in that job
 indefinitely. Those of us who want a larger lab of our own can use the
 position to create preliminary data and apply for grants to do it – either
 to “earn” more lab space at the same institution or apply for positions at
 other institutions.

 7) Limit the number of employees that an individual faculty scientists (or
 “permanent” scientists in federal agencies and national labs) lab can have –
 limit on grad students, postdocs, and technicians. Possibly only limit
 trainees (grad students and postdocs). This will allow faculty scientists to
 actually focus more on science and less on administration of large
 laboratory empires. Often the lab bosses are disconnected from much of the
 research going on in the largest labs. This causes an ackward situation
 whereby the indepdent scientist (postdoc, etc.) who conceived and conducted
 the research must add the boss to a senior position on the grant or
 publication artificially, thus making it impossible to distinguish whose
 ideas they were and who did the work, further exacerbating the difficulty
 for the employee to get their own independent position and lab. This
 situation has a severely negative impact on the innovation per dollar of
 federal funding.

 8) End the system of tenure for faculty, it's an out-dated system which
 severely hampers innovation, reduced career opportunities in science and
 incentivizes exploitation and laziness.

 9) Make

our lab focuses on interactions between ecological and evolutionary
processes. As community ecologists, we are interested in how species
interactions affect species and genetic diversity in communities. In
particular, we are interested in how rapid evolution affects species

Current research projects in the lab focus on (1) interactions among
bacteria and protozoa that live inside carnivorous pitcher plants, (2) the
evolution of mutualisms between corals and symbiotic dinoflagellates, and
(3) genetic diversity in invasive species in California grasslands.
Students are welcome to develop independent research projects in any of
these systems, but are also encouraged to explore other systems in which
eco-evolutionary research questions can be tested. Our website is about to
undergo a re-launch with new information in January, but meanwhile there is

[ECOLOG-L] Graduate Student Positions in Evolutionary Ecology

2013-02-06 Thread Casey terHorst
The terHorst Lab is recruiting 1-2 students to the Master’s program at 
California State University, Northridge for Fall 2013. Research in my lab 
generally focuses on community ecology and the factors that allow species to 
coexist. In particular, I am interested in how rapid evolution on contemporary 
time scales alters the outcome of species interactions and affects coexistence 
and genetic diversity in communities. My research combines theoretical and 
experimental approaches that bridge the gap between evolutionary biology and 
community ecology. More information is available at 
http://www.msu.edu/~terhors3   

I have used several systems to explore these questions, including interactions 
between invasive and native species in California grasslands, natural microcosm 
communities inside carnivorous pitcher plants, symbioses between corals and 
algal symbionts, and communities of epifaunal marine invertebrates. Students 
are welcome to work in any of these systems, but are also encouraged to develop 
work in other appropriate field or laboratory systems. Projects that include a 
theoretical component are encouraged, so programming skills are useful, but are 
not required. Some examples of potential Master’s student projects are: (a) 
genetic variation in invasive ability and selection on traits during invasion, 
(b) the effect of gene flow on local adaptation in natural microcosm 
communities, (c) contemporary evolutionary responses to global change.  

Northridge is located in the San Fernando Valley in Los Angeles and provides 
access to many different natural habitats. The location is within a short 
commute of West LA, Santa Monica, Hollywood, or most locations in the Valley. 
The Biology program at CSUN has a reputation of turning out excellent Master’s 
students who often continue on to top-tier Ph.D. programs. More information 
about the Biology program is available at http://www.csun.edu/biology  

Interested candidates should send email inquiries to casey.terho...@kbs.msu.edu 
describing their career goals and previous research experience. Include a 
CV/resume, if appropriate. You should also give a sense of your research 
interests, but these need not be specific plans, as students will be encouraged 
to develop their own independent projects during their first year. 
Underrepresented groups in ecology are especially encouraged to apply. 
Applications to CSUN are due by March 15, but potential applicants should 
contact me well before then to determine whether or not you should apply. 
Interested applicants can also meet with me at the Benthic Ecology Meeting in 
Savannah, GA from 3/20-3/24.

Re: [ECOLOG-L] planned contrasts replacing 2-way ANOVA

2010-07-07 Thread Casey terHorst
There should be no problem with using a priori contrasts.  No  
adjustment of the p-value is required, UNLESS the contrasts are  
non-orthogonal, which is often the case when more than two hypothesis  
tests.  If the contrasts are not orthogonal, some type of adjustment  
(e.g. Bonferroni) is required, which will lower the power you would  
otherwise gain with a planned contrast.

I am planning a 2x2 factorial experiment whe
Dear list members,


I am planning a 2x2 factorial experiment where I record several response
variables to test several hypotheses.
Some of these hypotheses can be tested using the usual 2-way ANOVA.  
That is, the

significance or non significance of the two main effects and their
interaction is expected to provide sufficient information to draw conclusions
regarding these hypotheses.
However, another hypothesis focuses on one of the four treatment
combinations, and would be best approached by comparing this focal treatment
with the other three. However, if I use the 2-way ANOVA, some  
possible results

may be inconclusive, and require further post hoc analyses with
a reduced threshold for significance.

Since my a-priori hypothesis calls for 3 specific contrasts, it makes
statistical sense to me that I can skip the 2-way ANOVA and only  
perform these 3
contrasts without reducing the significance threshold. The logic  
behind this is
that these 3 planned contrasts replace the 3 component tests of the  
2-way ANOVA

procedure (2 for the main effects and one for their interaction) that are
each always done without any change to the significance threshold.

Though I have found support for this approach on online statistics lectures
notes, I have never seen it taken in any published study, and I  
wonder if it is

indeed kosher (and if it can be expected to pass reviewers).
I would highly appreciate input on this, and especially references  
to back this

approach in case it is valid.

Thank you very much, 
 
Asaf  






Re: [ECOLOG-L] Are ecologists the problem?

2009-09-09 Thread Casey terHorst
There was an interesting article in the August issue of Frontiers in  
Ecology and the Environment that suggests ecologists have a much  
larger carbon footprint than the average American, largely because of  
air travel to meetings, field sites, etc.

Quoting Kevin McCluney kevin.mcclu...@asu.edu:


I recently attended the 2009 annual meeting of the Ecological Society of
America (ESA).  The theme of this year’s meeting was sustainability.  There
were many great talks on this subject and a few truly pessimistic ones.  One
speaker proposed that human beings are, by our very nature, destined to
consume and reproduce as much as possible, and despite our best efforts,
this will lead to our own demise.  During the same talk the speaker also
asked, “who is responsible?”  He answered his question by saying that we at
this conference are just as much a part of the problem as anyone else.

Is this true?  I know I myself have taken many steps to lower my footprint
and many other ecologists have as well.

For instance, at last year’s ESA meeting in Milwaukee there was an
interesting occurrence at local restaurants.  The first night of the
conference I had a really good veggie burger at one restaurant.  I went back
later in the week for another.  The waitress apologized… they were all out.
She went on to explain that the manager had heard our conference was coming
to town, so bought extra ahead of time, but ran out of those quickly anyway.
The manager then went to the local grocery store and bought more.  But alas,
by the time I returned, they had run out of those as well.  Further, when I
dine with friends at ESA meetings, I often find that more than half the
table orders vegetarian entrees.

Why does eating vegetarian matter so much?  Modern, industrialized livestock
production is one of the more environmentally destructive human endeavors.
It contributes roughly one fifth of all our greenhouse gas emissions, more
than all cars, and these gases are major contributors to the rapid climate
change we’re experiencing.  Livestock production also may, in certain cases,
be leading to deforestation and destruction of important ecosystems, as well
as to pollution of rivers, lakes, and even oceans.  In addition, we all know
that basic ecological principles hold that it takes less resources to raise
plant based food sources than meat based, since energy is lost as you move
up the food chain.  Thus we can feed more people and use fewer resources on
a plant-based diet.  All this caused the chairman of the Intergovernmental
Panel on Climate Change recently to proclaim that the best thing a person
could do to reduce their impact on climate change was to eat a more plant-
based diet.

My wife and I haven’t stopped at eating low on the food chain.  We’ve also
joined community supported agriculture, where we buy a share of produce from
a local farm.  The farmer gets upfront economic security and we get very
affordable, local, fresh organic produce.  We pay just $18 per week for a
large bag of food.  At this price we can afford to supplement our diet with
additional organic items from the grocery store.

We’ve also taken a variety of other steps, from riding my bike to work, to
offsetting car and air travel through renewable energy from an independently
certified company, to buying 100% of our electricity from renewable sources
through our local utility for as little as $15 per month.

While we may not be reaching the small ecological footprint of those in many
third world countries, we’ve done our best to come in line with our  
planet’s

limits while maintaining a decent quality of life.

So, are ecologists just as much a part of the problem as everyone else?  Are
all ecologists the same?  What are the variety of lifestyle choices made by
ecologists?  Not only would the answers to these questions provide a
response to the ESA presenter, but I think the answer would be interesting
to a wide audience.  I propose that ESA conduct a poll of members, asking
questions about lifestyle choices and demographics, comparing ours to that
of the general public.  If we are not different, this would be a bit of a
wake-up call.  However, if we are different, then perhaps some of our
lifestyle choices would be informative to understanding how to achieve a
more sustainable society.

If there is one thing I learned from a cultural anthropology course I once
took, it was that there isn’t just one right way to live.  Human cultures
throughout the world are very diverse.  But, from the inside of one culture
it is often very hard to see other ways to live.  Let us not be trapped in
our culture, but seek a better understanding of all the ways of living, so
that we might find a more sustainable path.

Re: Is biodiversity an ecosystem function?

2007-04-20 Thread Casey terHorst
I've always had difficulty understanding how a static measure (such as
biodiversity, or even something like biomass) can be called a function.  This
is partly just a semantic issue, but largely a real issue as well.

Quoting Fabrice De Clerck [EMAIL PROTECTED]:

 I have a quick question for the listserve for which I would be
 interested in hearing people's opinions, and experiences.

 The question is: Is biodiversity an ecosystem service?

 Those of us that work in biodiversity and ecosystem functioning
 studies typically regard biodiversity at the provider of services and
 functions. Tilman's biodiversity and productiity, the biodiversity
 and stability work, biodiversity and pollination (Klein),
 biodiversity and pest control (Perfecto).

 Meanwhile in much of the development and economics literature,
 biodiversity itself is a unique service and function where it is not
 uncommon to see people state that we will work with farmers to
 improve the capacity of coffee farms to provide critical ecosystem
 services such as carbon sequestration, biodiversity and water.

 Are both correct or is it important to distinguish between
 biodiversity serving as a function, and biodiversity as the provider
 of services.

 All comments are welcome on- or off the listserve.

 Cheers,
 Fabrice
