Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations ... in population management. For example ...
The source–sink model of population dynamics has made contributions to many areas in ecology. For example, a species' niche was originally described as the environmental factors required by a species to carry out its life history, and a species was expected to be found only in areas that met these niche requirements. [18]
Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover ; [ 3 ] [ 4 ] using the transect method , as done for the mountain plover ; [ 5 ] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in ...
A well-known example of a cline is the skin color gradation in indigenous human populations worldwide, which is related to latitude and amounts of sunlight. [27] [28] Ecotypes may display two or more distinct and discontinuous phenotypes even within the same population.
A 1982 study by Templeton and Johnson showed that in a population of Drosophila mercatorum under K-selection the population actually produced a higher frequency of traits typically associated with r-selection. [37] Several other studies contradicting the predictions of r/K selection theory were also published between 1977 and 1994. [38] [39 ...
Minimum viable population (MVP) is a lower bound on the population of a species, such that it can survive in the wild. This term is commonly used in the fields of biology , ecology , and conservation biology .
In ecology, a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding. [2] [3] The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the area and more probable than cross-breeding with individuals from other areas.
