• American Bison (Bison bison) are a keystone species in prairie grassland ecosystems. • Bison experienced a severe genetic bottleneck in the late 1800s and their numbers declined drastically. • The species recovered from the bottleneck and now there are more than 500,000 bison today. • Hybridization with cattle has threatened bison fitness and genetic adaptations necessary for survival in North American grassland habitats. • Bison are found in both Federal and private herds around North America. Objectives: • Identify bison individuals located at Rio Mora NWR that have genetic evidence of cattle introgression in mitochondrial DNA. • Identify lineages in the bison herd at the Rio Mora NWR.

Plan to Increase American Beaver Populations at Rio Mora National Wildlife Refuge, NM Goals: Grow beaver population in Rio Mora National Wildlife Refuge to 20; Improve and expand habitat; Deter bison from beaver habitat

With an open landscape and semiarid climate, short grass prairies support unique biodiversity, including bison, songbirds and a variety of grass species.

This service learning partnership with RMNWR provides information about native plant species germination percentages and conditions that plants encounter. Rio Mora can use this information begin their restoration with a seed mix that is successful and resilient in the local habitat.

River otters have been successfully reintroduced to other NM rivers. If the Mora River is similar to these systems, then the biomass & production rate of fish and crayfish will sustain the min. river otter dietary requirements.

An exploration of the hypothesis that because river otters have been successfully reintroduced in other New Mexican rivers, the Mora River will also likely be a suitable ecosystem for their reintroduction.

The invasion of the American Bullfrog leads to the loss of native biodiversity and can eventually drive some species into extinction. The American Bullfrog were established in the RMNWR in Northern New Mexico during the last century.
