"Ecological dynamics of multispecies communities"Alan McKane , Department of Physics -University of Manchester, UK [Host: Tim Newman]
ABSTRACT:
Many theoretical physicists with a background in non-equilibrium statistical
mechanics are becoming interested in exploring mathematical models of
ecosystems. The reason for this is clear when one realizes that such models
typically involve a large number of individuals interacting according to
simple rules and that the ultimate aim is to compute coarse-grained or
long-time behavior. The ingredients of these models include population
dynamics, predator-prey interactions, competitive effects, speciation
and immigration. Two examples will be discussed. One is a model which
describes the evolution of food webs using adaptive dynamics and the other,
a stochastic model of species-rich ecosystems which makes predictions
concerning the form of the species abundance distribution.
