Wildebeest migrating in the Serengeti. Migration, in ecology, is the large-scale movement of members of a species to a different environment.Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type.
Gene flow is the transfer of alleles from one population to another population through immigration of individuals. In population genetics, gene flow (also known as migration and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent ...
Goose migration is an iconic migration phenomenon in parts of the Northern Hemisphere [1]. Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis.
When discussing population dynamics, behavioral ecology, and cell biology, recruitment refers to several different biological processes. In population dynamics, recruitment is the process by which new individuals are added to a population, whether by birth and maturation or by immigration. [1]
Population size can be influenced by the per capita population growth rate (rate at which the population size changes per individual in the population.) Births, deaths, emigration, and immigration rates all play a significant role in growth rate. The maximum per capita growth rate for a population is known as the intrinsic rate of increase.
Cell migration is a central process in the development and maintenance of multicellular organisms.Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations.
Migration (ecology), the large-scale movement of species from one environment to another Animal migration; Bird migration; Plant migration, see Seed dispersal, the movement or transport of seeds away from the parent plant
Immigration of species onto the island was then observed in a first and second year census. Wilson and Simberloff confirmed that there was an inverse relationship between the number of species on an island and the distance to the source region as predicted in The Theory of Island Biogeography .
