This dataset consists of the microsatellite genotypes, collection data, and ownership data for 1461 specimens of Bombus occidentalis. The dataset includes both recognized subspecies, Bombus occidentalis occidentalis and Bombus occidentals mckayi. The subspecies have since been elevated to species status and are currently described as Bombus occidentalis and Bombus mckayi. The specimens were collected from across the historical species range primarily between 1960 and 2020, with few specimens from earlier than 1960 and the oldest from 1904. The specimens are owned and housed by 10 different institutions, which is noted for each specimen.

Aspen is a highly valued tree species in western forests, but it has been declining due to drought, herbivory, and fire suppression. Fire suppression has contributed to aspen’s decline because post-fire environments provide more opportunities for aspen to regenerate, both by resprouting and by seed. Regeneration from seed in these post-fire settings is particularly valuable because it increases aspen population genetic diversity and resilience. However, natural seeding events are not common, and mortality rates for seedlings are quite high. Nursery-grown seedlings provide a promising alternative and an opportunity for assisted migration, but planting protocols have not been well developed and mortality rates for...

A study commissioned by the Utah Division of Water Quality and the Colorado Water Quality Control Division. Study was carried out by Utah State University. The overarching goal of the study was to conduct a comprehensive search and synthesis of existing records on the historical and current presence of ammonia-sensitive freshwater mussels (Superfamily Unionoidea) and non-pulmonate snails (Valvatidae, Hydrobiidae) in Utah and Colorado. In addition to these targeted species, other species belonging to Class Bivalvia and freshwater Gastropoda were also included. Though they were not actively sought during record searches, occurrence of non-native species such as the New Zealand mud snail (Potamopyrgus antipodarum),...
