Document Summary
Population a group of potentially interbreeding individuals of a single species inhabiting a specific area. Population ecology the study of the spatial and temporal patterns in the abundance and distribution of organisms and the mechanisms that produce those patterns. Number of individuals in the population at a certain time. Number of births (b), deaths (d), amount of immigration (i) and emigration (e) at a certain time. Individual rates of processes scale up to influence population size (n) Simple equations (shown on right) always true. The 4 factors are not the only ones that can affect population size. Multiple populations live together and contribute to immigration and emigration. Describe the rate for the total population (ie. total number of births for an entire population) Denoted by capital letters (ie. b is the total birth rate of the population) Describe the rate for an individual (average) (ie. the birth rate per individual in the population)
