This animal has been historically considered a member of genus Arvicola, but molecular evidence demonstrates that it is more closely related to North American Microtus species. [ 2 ] [ 3 ] Water voles are on the USDA Forest Service Region 2 sensitive species list because they maintain very small populations and there is high concern that their ...

In Pennsylvania, three subadult eastern meadow voles were captured at least 1.6 miles (2.6 km) from the nearest appreciable suitable eastern meadow vole habitat, suggesting they are adapted to long-distance dispersal. [21] In Ohio, the effects of patch shape and proportion of edge were investigated by mowing strips between study plots.
Eusocial insects like ants and honey bees are multicellular animals that live in colonies with a highly organized social structure. Colonies of some social insects may be deemed superorganisms. [6] Animals, such as humans and rodents, form breeding or nesting colonies, potentially for more successful mating and to better protect offspring.
New colonies are founded in a clumped pattern, around the mating sites. [11] [13] The population may self-thin through direct interference competition [11] resulting in a uniformly overdispersed distribution pattern. [11] Long-term colony survival is mediated by proximity to older colonies. [32] Smaller colonies have closer nearest neighbors. [11]
This list of mammals in Pennsylvania consists of 66 species currently believed to occur wild in the state. This excludes feral domesticated species such as feral cats and dogs . Several species recently lived wild in Pennsylvania, but are now extirpated (locally, but not globally, extinct).
In other Vespula species, polygyny tends to be found in mild climates where the colony can last more than a year. Given that many of this species live in temperate or subtropical environments, perennial nests have been observed. Polygynous perennial colonies occur when reproductive females (queens) reproduce in the colony instead of leaving it.
The land ceded covered, partially or in the entire, the U.S. states of New York, Pennsylvania, Maryland, Virginia, West Virginia, Kentucky, Ohio, Tennessee and North Carolina. They were bordered to the west by the Algonquian lands in the Ohio Country, Cherokee lands to the south, and Muscogee and Choctaw lands to the southeast.
