In Greening Arctic, Caribou and Muskoxen Play Key Role

The story of Arctic greening has overlooked some main characters. At center stage are climate change and warming temperatures. Meanwhile, large grazing wildlife, such as caribou and muskoxen, also play a key role in the timing and abundance of Arctic plants, according to a study from the University of California, Davis.

Chinook Salmon Face Habitat Challenges

Chinook salmon are facing unprecedented challenges as their once-thriving populations struggle to survive. A new study published in the journal Ecosphere suggests that decades of human activities, including ocean harvest, artificial propagation and reservoir construction, have not only reduced the size of these fish, but also disrupted their ability to spawn successfully.

U.S. Reservoirs Hold Billions of Pounds of Fish

After nearly a century of people building dams on most of the world’s major rivers, artificial reservoirs now represent an immense freshwater footprint across the landscape. Yet, these reservoirs are understudied and overlooked for their fisheries production and management potential, indicates a study from the University of California, Davis. 

In Hotter Regions, Mammals Seek Forests, Avoid Human Habitats

The cool of the forest is a welcome escape on a hot day. This is especially true for mammals in North America’s hottest regions, according to a study from the University of California, Davis. The study indicates that, as the climate warms, preserving forest cover will be increasingly important for wildlife conservation.

Heat Waves Negatively Impact Bird Reproduction in Agriculture

Bird populations are in rapid decline across North America. While climate change is just one of the many factors influencing North American birds, its effects are significant and can interact with other stressors, such as habitat loss. A team of University of California, Davis, researchers found that the effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home.

State and Federal Fish Agencies Take Urgent Actions to Save Spring-run Chinook Salmon

The California Department of Fish and Wildlife (CDFW) and National Oceanic and Atmospheric Administration (NOAA) Fisheries biologists are pursuing urgent measures this fall to save some of the last remaining Central Valley spring-run Chinook salmon after the numbers returning from the ocean this year fell sharply toward extinction.
