Population Ecology
Population ecology is the branch of ecology that studies the structure and dynamics of populations. In population ecology a population is a group of individuals of the same species inhabiting the same area. In contrast to genetics, where the population is a group of interbreeding individuals of the same species, which is isolated from other groups and in human demography, the population is the set of humans in a given area. Population density is a common biological measurement and is often used by conservationists as a more appropriate measure than absolute numbers. If there are low population densities, extinction may be in the future of the species life, but is unlikely to occur and a reduced reproduction rate can also be a result. Low population densities result in reproduction to decline due to the increased problems with locating mates, increased interbreeding, and increased susceptibility to catastrophic events. Different species will have different population densities.......
