Like math and plant community ecology?
I am recruiting one or two new Ph.D. students to work on theory and its integration with data in the areas of forest dynamics, species coexistence, or plant community ecology more generally.
Deadlines for the EEB and Plant Biology programs are Dec. 1.

We are doing spatial patterns in class tomorrow. So please enjoy my simulation of Pokemon battles on a lattice. Pokemon attack a random neighbor and winners are based on the game's hierarchy (water > fire > ice ...). Some amazing spatial patterns emerging from 7-way rock-paper-scissors!

Biological modeling is organized inquiry, but how should we think about the process?
My new paper in #EcologyLetters argues that we should model like experimentalists: define treatments, measure responses, validate, perturb, repeat.

Do you agree?
