" Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.

Populations of several parrot species were described mainly in the unscientific writings of early travelers, and subsequently scientifically described by several naturalists ( to have their names linked to the species that they were proposing ) mainly in the twentieth century, with no more evidence than the earlier observations and without specimens.

Populations that have a steady, substantial gene flow among them are likely to represent a monotypic species even when a fair degree of genetic variation is obvious.

Populations of this species have declined in the 20th century and some island populations are endangered by hunting, accidental poisoning, and collision with power lines.

Populations appear to be stable, so the species is considered of Least Concern.

Populations can be dense and territories can shift quickly, especially for species of the extreme shallows ( a few centimetres of water ).

Populations have seen significant increases since the protection programs began, but the species remains in serious danger.

Populations of feral animals present good sources for studies of population dynamics, and especially of ecology and behavior ( ethology ) in a wild state of species known mainly in a domestic state.

Populations appear to remain stable and it has not reached the threshold of inclusion as a threatened species, which requires a decline of more than 30 percent in ten years or three generations.

Populations from the Pacific Coast of the United States are genetically distinct from those of G. sabrinus found elsewhere in North America, although they are considered to belong to the same species.

Populations of the Blue-headed Vireo have been steadily increasing since the 1970s and has therefore been classified as a " Least Concern " species in 2004.

Populations in the southwest Pacific, formerly included in C. vittatus, are actually a separate species, C. francisi.

Populations are also found in Madagascar, but it is doubtful if this within the native range of the species.

Populations in cold continental climates mostly have one clutch per year, forming species A, whereas those in warmer climates have two clutches per year, forming species B. European earwigs are most commonly found in temperate climates, since they were originally discovered in the Palearctic region, and are most active when the daily temperature has minimal fluctuation.

Populations have also been introduced outside of the former range of the species to Kenya, Uganda and Zambia.

Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species ' low germination rates.

Populations can be considered any plant or animal species, human genders, followers of a certain religion, people of different nationalities, stone types, ethnic groups, etc.

Populations of the same species from different latitudes may also follow Allen's rule.

Populations have declined considerably since European settlement, mainly as a result of widespread habitat destruction and predation by mammalian invasive species.

Populations can change through three processes: fertility, mortality, and migration.

Populations are primarily declining due to habitat being lost to development, especially in coastal swamp thickets and woodland edges in the east and riparian habitats in migration and winter in the Southeastern United States and Mexico.

Students have created areas of concentration ranging from " 20th Century American Literature " and " Adaptive Physical Education for Vulnerable Populations ," to " World Politics and Social Change " and " Zoological Photography.

Populations also extend for considerable distances inland in regions with enough moisture to support suitable woodlands.

Populations in the Oswego River are being actively managed for recovery.
