Document Summary
Demography/demographics: demography is the statistical study of populations. Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. It is the study of how the population sizes of species groups change over time and space: focus is on demography, types of models, single species, multiple species (community) Density-dependent factors: a limiting factor that depends on population size is called a density-dependent limiting factor, density-dependent factors operate only when the population density reaches a certain level. Carrying capacity: the carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. Birth rate and death rate: birth rate (technically, births/population rate)- is the total number of live births per.
