Releasing aquarium fish into local waterways — or down the toilet — can damage aquatic ecosystems in a number of ways. The fish themselves can become an invasive species, they can disrupt habitats for other fish and aquatic species, and they may introduce secondary problems such as harmful pathogens or other aquarium species (seaweed, snails) into the waterways.

At least 13 of the 102 aquarium species that are imported into California have been introduced into California marine waters, according to a recent report by Susan Williams, professor in the...

The red fox (Vulpes vulpes) is one of the most widely distributed terrestrial mammals in the world. California is home to red foxes of both native and non-native ancestry. Red foxes in the Sacramento Valley were long thought to be non-native. However, in 2005 genetic analyses performed in the UC Davis School of Veterinary Medicine’s, Veterinary Genetics Laboratory revealed these foxes to be native to the region and potentially in decline.

The estimated population size of Sacramento Valley (SV) red foxes is very small, indicating possible conservation concerns. In addition, SV red foxes occur in a highly modified landscape used for intensive agriculture. In particular, while preliminary...

After just experiencing my first Davis summer, I find it hard to describe anything in Davis as cool. But according to Sierra Magazine, UC Davis is just that. So much so, that the school was recently named the #1 Coolest School in the nation. Granted, they weren’t talking about the weather. Instead, they were referring to UC Davis’ environmental stewardship.

With all that UC Davis does to create and promote environmentally friendly programs and facilities, it’s no wonder the university just...

From California’s Ponderosa fire to Colorado’s record-breaking Waldo Canyon fire and other blazes burning across the West, the summer of 2012 -- like many recent summers -- has been marked by a long, intense wildfire season. It has claimed thousands of acres, hundreds of homes, and in some cases, lives.

Malcolm North, professor in the Department of Forest Ecology at UC Davis and U.S. Forest Service research scientist, studies the effects of fire on Sierra Nevada coniferous forests. In this video, North explains how climate change and a history of fuel suppression in the forest mean wildfires will burn hotter, faster, longer and more often --...

A pair of leading UC Davis experts will provide a rare glimpse into efforts to protect California biodiversity at a public lecture May 10, 4–6 p.m., in the UC Davis Conference Center.

Lisa Thompson, a UC Cooperative Extension specialist and director of the Center for Aquatic Biology and Aquaculture, will discuss how the campus’ specialized aquatic laboratory plays a crucial role in research into endangered and threatened fish such as Delta smelt and green sturgeon. Ted Grosholz, an environmental sciences and policy professor and UC Cooperative Extension specialist, will share his insights into the...
