Document Summary
Characteristics of populations size and density (these are key) sex ratio gene frequencies (distribution of population) Collection of traits that describe major events age of rst reproduction number of young number of reproductive events life span mortality (how old was it?) Correlated life history traits these traits are often found together in a species basically impossible to start mixing and matching traits across these packages the reason for this is because there are life-history tradeo s. Package a (mice) breed young many small babies breed often die young small body size little parental care. Package b (elephants) breed late few large babies breed rarely die old large body size long parental care. Population losses = d assume that immigration and emigration are the same - and that they cancel out controls for population this gives us a per capita rate of birth and mortality.
