Removing Barriers to River Health
While many large dams in North America deliver invaluable services—like critical water supplies, clean hydroelectric power, reduced flood risks and recreational opportunities—many more no longer serve their intended purpose and create serious safety and environmental concerns.
California Asked to List Mountain Lions as Endangered
Wildlife organizations asked the California Department of Fish and Wildlife Tuesday to provide new protections for mountain lions in the Golden State.
Bike expedition raises awareness of climate change in California

Declines in Insect Abundance and Diversity: We Know Enough to Act Now
Insects provide services of over $57 billion to the US economy. Although we need more study to understand the overall scope and scale of the declines, the research that has been done provides compelling evidence of declines in insect abundance, diversity, and biomass.
Declines in insect abundance and diversity: We know enough to act now
Recent regional reports and trends in biomonitoring suggest that insects are experiencing a multicontinental crisis that is apparent as reductions in abundance, diversity, and biomass.
Evolution Fast Track: Otter Genetic History Provides Clues for Future Recovery
Unlike whales and dolphins that have lived in the marine world for more than 50 million years, sea otters have only had about 5 million years to develop the suite of adaptations necessary to survive the harsh conditions of life in the sea. What happened genetically to assist in that incredible transition?
