Evolving in the Community

Evolving in the Community

(p.76) Chapter Three Evolving in the Community
Evolutionary Community Ecology

Mark A. McPeek

Princeton University Press

This chapter examines how species in simple community modules evolve in order to adapt to one another. It first considers the ecological basis of natural selection before discussing the three general types of traits that underlie the trophic interactions between predators and their prey. It then explores how the type of traits involved in species interactions affect the dynamics of adaptation and describes the underlying dynamics of adaptation when all the species in a simple community module can coevolve, along with the influences of various system features on the outcome of this coevolution. The chapter focuses on the simultaneous dynamics of abundances and traits that result from species interactions by looking at the case involving one resource and one consumer, with only trait being ecologically important for each species, and how this simple consumer-resource system evolves when a third trophic level is added to the system.

Keywords:   species, community module, natural selection, trait, trophic interaction, predator, prey, species interaction, adaptation, coevolution
