Integrated pest management is an ecologically based pest- control strategy that relies on natural mortality factors such as natural enemies, weather, and crop management, and seeks to disturb these factors as little as possible. Longevity is the age at death of an animal. Metapopulation is a group of subpopulations each isolated in a patch of habitat. The persistence of the metapopulation is dependent on the persistence of the subpopulations and movement of animals among subpopulations to exchange genes. Monogamy is a mating system in which each male mates with one female only.
Natality refers to number of young individuals born or hatched per unit of time.
Nest cycle is the time required for a species to build a nest, lay and hatch eggs or give birth, and fledge or wean young. Most songbirds and small mammals will attempt to breed repeatedly during the breeding season. Polygyny is a mating system in which successful males mate with more than one female. Population is a biologically, geographically, or politically defined group of animals composed of all of the individuals of a species in a particular area. Population dynamics is the study of changes in the number and composition of individuals in a population, and the factors that influence those changes.
