Lecture 27 - Interspecific Competition

Lecture 27 - Interspecific Competition

This video was recorded at EEB 122 - Principles of Evolution, Ecology and Behavior. Competition among species, or interspecific competition, can have an even greater effect on selection than competition within species (intraspecific competition). This is often the case in lower density populations. Different species can have positive, neutral, or negative effects on each other's fitness, and the effect species 1 has on species 2 is not necessarily the same that 2 has on 1. The effects that cohabiting species have on each other shapes evolution the same way that selective pressures from within a species or the physical environment shapes it.
