Cervus

The genus Cervus is a taxonomic genus of deer. Members of this genus are found in eastern Asia, many of the western island chains in the Pacific Ocean, and in North America. North American individuals in this genus likely descend from ancestors that crossed the Bering Land Bridge shortly after the global flood.

Anatomy
Members of genus Cervus tend to be larger than other genera of the deer family. The largest species are the red deer and the North American elk. However, the moose or "European elk" (Alces alces) is larger than any of these.

Reproduction
Reproduction is sexual, as is the case with all deer. Specific mating behaviors vary at the generic and species level.

Ecology
Species in this genus tend to adapt readily to a wide variety of wild environments. They tend not to thrive in and among human-settled regions.
