Top Cats: How Pumas and Other Apex Predators' Populations Affect The Big Biodiversity Picture
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.

Coyote Killings: A Complex Debate of Conservation and Cruelty
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.

California Wildlife Mural Celebrates Its Third Birthday
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.

Picturing Biodiversity: Cultivating an Eye for Conservation
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.

Salmon Runs, Grizzly Bear Dreams
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.

Fair Game? On Lions, Hunters and Wildlife Policy
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?

Small Rewards: Tiny Frogs and Chameleons Find and Fill a Niche
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.

A Birder’s-Eye View of Conservation
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.

Everything is Illuminated, All the Time
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.

Sudden Oak Death Plus Wildfire: A Natural Experiment
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.

Oil Spills and the Environment
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.
