California recently passed a law that will ban the use of lead ammunition when taking wildlife with a firearm. The intent is to protect scavenging birds and other wildlife from the threats of lead poisoning from spent lead ammunition.
While the new law, which was passed on Oct. 11, 2013, will be phased in over the next six years, the research that helped shape it has been going on for some time and much of it was done by researchers at the University of California, Davis.
UC Davis wildlife epidemiologist Terra Kelly (in photo at right) studied the effects of big game hunting on lead exposure in carrion-eating birds like eagles and turkey vultures and monitored the effect of a 2008 law that made it...

In the Pajaro Valley, an agricultural region in Monterey County, residents are being proactive about water conservation policies and seeking ways to save water.
Groundwater makes up roughly 90 percent of the water delivered by Pajaro Valley’s Water Management Agency (PVWMA). There is a current overdraft of groundwater in the aquifers of this region, which calls for immediate action to protect their water source. Historically, the amount of groundwater in the aquifer was above sea level so the amount of salt water in the freshwater aquifer was kept at bay. Removing too much water from the ground at a faster rate than it is being replenished has caused seawater from the Pacific Ocean to enter the aquifer as the water...

It's no big surprise that humans are impacting the planet. But a new study pinpoints a sobering connection.
As human life expectancy increases, so does the percentage of invasive and endangered birds and mammals, according to a study by the University of California, Davis.
The study, published in the September issue of Ecology and Society, examined a combination of 15 social and ecological variables — from tourism and per capita gross domestic product to water stress and political stability. Then researchers analyzed their correlations with invasive and endangered birds and mammals, which are two indicators of...

Calcium can do much more than strengthen bones. The mineral is a critical nutrient for healthy tree growth, and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain.
The paper reports on 15 years of data from an ongoing field experiment in the Hubbard Brook Experimental Forest in New Hampshire led by study co-author Charles Driscoll Jr., professor of...

What’s a honey bee to do?
The dwindling resources of pollen and nectar-producing plants in California greatly concern bee scientists and beekeepers, and rightfully so.
But the dwindling resources also greatly concern native pollinator specialists and native plant enthusiasts. Some worry that honey bees, which are non-natives, may be "reducing" or "eliminating" native pollinators through competition for food.
Extension apiculturist Eric Mussen of the UC Davis Department of Entomology and Nematology explains that a number of agencies and organizations are cooperating in an effort to "restore" regions of the California Central...
