Conservation of endangered fishes commonly includes captive breeding, applied research, and management. Since 1996, a captive breeding program has existed for the federally threatened and California endangered Delta Smelt Hypomesus transpacificus, an osmerid fish endemic to the upper San Francisco Estuary. Although this program serves as a captive refuge population, with experimental releases being initiated to supplement the wild population, it was uncertain how individuals would survive, feed, and maintain condition outside hatchery conditions.

- Fossil evidence on the evolutionary origins of modern desert bighorn sheep is unclear, prompting researchers to study the genetic diversity and relationships among different subspecies in southwestern North America.
- By analyzing DNA from 804 individuals across 58 locations, researchers identified two major genetic groups corresponding to the Sierra Nevada and Rocky Mountain bighorn sheep, indicating a divergence from desert bighorn sheep during the Illinoian glaciation.
- The findings suggest that desert bighorn sheep consist of several recently diverged lineages, highlighting the importance of managing these subspecies as distinct groups to conserve biodiversity, as they originated from separate populations during the Pleistocene era.
