[ECOLOG-L] Grad student assistantships in cyanobacterial ecology

2009-09-02 Thread David Bird
Opportunity to study cyanobacterial ecology in 
the beautiful lakes of southern Quebec. Both 
M.Sc. and Ph.D. students accepted. Current 
interests are in physical-biological coupling, 
ecophysiology, community dynamics, methods 
development, factors of control, and toxin dynamics.


The UQAM is a French-speaking university, so 
M.Sc. students should know French or be willing 
to learn. Ph.D. students take almost no courses 
so they can survive with no French, but they will 
miss out unless they too take the plunge to learn 
French. We have a large group of aquatic 
scientists at UQAM and we are part of a larger 
limnological research association - the GRIL.

Re: [ECOLOG-L] Ecology Laws and Speculations

2009-09-02 Thread William Silvert
Actually in ecology we don't so much use laws as principles, as Kent 
indicates. Although Conservation of Energy is considered a law in physics, 
its use in ecology is really that we try to construct budgets and follow 
energy and nutrients through the system.


Gauss' Principle of Competitive Exclusion illustrates an important 
difference between physics and ecology. Its use in ecology has suffered 
because of the criticism by Rob Peters that it is a tautology, but this 
would not faze a physicist, for whom the value of a law or principle depends 
on whether it is useful - and since the Competitive Exclusion Principle is 
useful, there would be no need for controversy, and niche theory would have 
a more significant role.


An example of a principle rather than a law dates back to my early work on 
gelatinous zooplankton, which many marine ecologists consider a dead end in 
the food chain. For me a basic principle is that if you leave food on the 
table, someone will eat it. It may take a million years to learn how, but 
someone will eat it. So my colleagues grudgingly granted that yes, 
leatherback turtles eat jellyfish, as do Mola molas, but that is an 
insignificant exception. But then more and more scientists started to tell 
me anecdotes about finding examples of predation on jellies, such as doing 
stomach content analysis on fish and finding just slime, but then realising 
that their hands were numb - presumably the fish had been eating jellies and 
the nematocysts were still active. So the principle led to knowledge, which 
is a useful result, although I would not call this a Law of Nature (even 
though it is #3 on Kent's list).


Turning to a broader picture, Complex Systems theorists have observed that 
there are some very general patterns in nature that seem to indicate an 
underlying universal structure. Vague rules such as 10% of the population 
has 90% of the wealth, 10% of streams carry 90% of water, 10% of the 
organisms compose 90% of the biomass, and so on, suggest that this is not 
just a coincidence. These patterns are very speculative, and many ecologists 
feel that speculation is unscientific, and therefore bad - no, not just bad, 
downright evil! I think that this holds back the development of ecological 
theory. By comparison, physicists love to speculate. The neutrino and the 
quark were hypothesized many decades before either was experimentally 
detected. The existence of helium was inferred from looking at the solar 
spectrum before it was actually found on earth. If only we could be that 
imaginative!

I'll have to remember that one indeed!  For our general (non-majors) Ecology

As far as I know, ecologists are pretty much in agreement on them!   And,
