Population Ecology Overview

Population = Group of individuals of the same species living in a defined area Natural selection = Process by which traits that enhance survival and reproduction become more common in a population over time Birth rates = Number of births per individual in a population Death rates = Number of deaths per individual in a population

All the cormorants in a wetland = Population Rats in an abandoned dwelling = Population Teakwood trees in a forest tract = Population Bacteria in a culture plate = Population

Births and deaths = Individual organism Birth rates and death rates = Population Per capita births and deaths = Population Change in numbers with respect to members of the population = Population

<p>Population ecology = Links ecology to population genetics and evolution Individual organism = Copes with a changed environment Natural selection = Operates at the population level to evolve desired traits Population = Has certain attributes compared to an individual organism</p> Signup and view all the answers
