Researchers have found declines in the number and diversity of bird populations at nine sites surveyed in northern New Mexico, where eight species vanished over time while others had considerably dropped.

Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.

Fishing quotas have been decided using an inadequate method for decades, according to a Scientific Reports study. The same method has also been used to decide about culling, hunting quotas, or translocating threatened species. Analysing the nuclear genome of sardines shows previously unrecognised genetic differences between populations, which are not identified by the go-to-method for Isolation-By-Distance, mitochondrial DNA analysis.

A long-term study of eastern massasauga rattlesnakes in Illinois reveals that -- despite their alarming decline in numbers -- the few remaining populations have retained a surprising amount of genetic diversity.

Putting land management in the hands of local communities helps the wildlife within, according to new research by a Penn State scientist. A new study demonstrates the positive ecological impacts of a community-based wildlife conservation area in Tanzania.
