Apex predators exert far-reaching effects on ecosystems that surface just decades after their disappearance. Santa Cruz researchers hope to understand how human activities and development affect how pumas use the landscape to help mitigate conflicts and plan for the species' long-term survival.
Coyotes, reviled for preying on sheep and goats, are the most targeted predator in the U.S. This week, hunters in the tiny Modoc County town of Adin will compete in a contest to kill the most coyotes to protect their livestock–even though research shows that killing coyotes results in higher reproductive rates.
Trophy hunters routinely pay thousands of dollars for the chance to kill big game like caribou, moose, black bear and especially grizzly bear. Trophy hunting narratives boast a love of nature. But some sociologists find a different story.
In 2009, after West Valley College built its brand new biology building, a group of faculty stood in the natural history lab staring at a blank wall. "It's too empty," they agreed. "How about a mural?" suggested biology and genetics instructor Molly Schrey.
Environmentalists have long relied on spectacular photography to show people why wilderness is worth preserving. The nonprofit ARKive builds on that tradition, using the power of wildlife imagery, from photos to film, to promote conservation of the world's threatened species, now approaching 17,000 plants and animals, based on the latest IUCN estimates.
Using grizzly bears in the Pacific Northwest as a proxy for the benefits salmon deliver to ecological communities, a new study argues that letting more salmon migrate into coastal streams will lead to downstream improvements for the ecosystem and eventually the offshore salmon catch.
Trophy hunting mountain lions is legal in every Western state except California. When the head of the state’s Fish and Wildlife Commission, a life member of the NRA, killed a young lion in Idaho, state legislators and environmental and animal welfare groups called for his resignation. What should Californians expect of state officials in charge of setting wildlife policy?
Recent discoveries of a Lilliputian lizard and elfin amphibian, fascinating in their own right, highlight one of the most enduring questions in biology: what controls the evolution of body size? They also provide a rare bright spot amid the relentless reports of endangered and disappearing amphibian and reptile species around the world.
The Great Backyard Bird Count gives novice Bay Area wildlife watchers the chance to play field biologist in their own backyards and help scientists gather data on the incidence, abundance, and distribution of birds. Researchers will use sightings to identify trends that will help conserve these valuable indicators of biodiversity.
The world is not as dark as it used to be. Light pollution can come directly from light bulbs, or it can bounce off of dust and water droplets in the air, creating a bright haze called skyglow. But there are ways to dim the lights and reduce their effects—and save energy in the process.

A natural experiment created by the overlap of the Basin Complex Fire and a UC Davis study allowed scientists to test whether SOD did in fact make wildfire worse. What they found was not what the news media or the firefighters predicted.

The volume of oil recently spilled in the Gulf of Mexico is several thousand times what was spilled in San Francisco Bay in 2007, but the ecological studies conducted in the wake of the SF spill give us an idea of what we can expect in the Gulf.

While new housing is stalled in the United States, there is lots of funding-in the billions of dollars-on the way for weatherization, residential energy efficiency, and renewable energy through the American Recovery and Reinvestment Act.

Through the eyes of these scientists, we witness the undersea life in bloom. They clearly have one of the best offices to go to work to each day.
