Mice share a similar set of genes to humans and gorillas. A catalog of the functions of all mouse genes could help in conservation efforts for endangered species.
A new study from the International Mouse Phenotyping Consortium, which includes the UC Davis Mouse Biology Program, shows how the growing catalog of mouse genes could be applied to save endangered species. The paper was published May 24 in the journal Conservation Genetics.
Koalas are one of Australia’s iconic animals, but they have been hard hit by an epidemic of Chlamydia infections contributing to a steep decline in numbers. Sick koalas brought to wildlife hospitals may be treated with antibiotics to clear up the chlamydia, but the antibiotics themselves can have severe side effects in the animals.

A new study led by Katherine Dahlhausen, a graduate student at the UC Davis Genome Center, published in the journal PeerJ, shows that those antibiotics may be changing the balance of gut microbes thought to allow koalas to digest eucalyptus leaves.
From improving crop production to tracking mosquitoes, the Stable Isotope Facility in the UC Davis Department of Plant Sciences supports a wide range of research on campus and throughout the world. December 1, 2017 marks the facility’s 20th anniversary and they are holding an open house today to celebrate.

Spring is in the air in California’s Central Valley. Birds are bathing in puddles that dot the landscape, and bats are swooping in and out of streetlights at dusk. Both groups of wildlife are feasting on bugs emerging after this winter’s epic rains.

The sight is a pleasant reminder of the abundance of wildlife that lives alongside us, performing tasks that inadvertently aid humans, such as natural pest control, pollination, and seed dispersal.

Applications like Facebook and Twitter show us, on a daily basis, the power of social networks to influence individual behavior. While wild animals do not surf the web, they are connected with other individuals in shared landscapes, and “share information” through their behavior. But how does this information affect surrounding animals?
The formation of multi-species groups, such as these fish feeding on a coral reef, may be fostered by social information sharing. (Heather Hillard)
With the third and final debate over, those voters who haven’t yet made up their minds will be focusing on their choice for President. But what do the woolly bear caterpillars of Bodega Bay have to say about the election?

The caterpillars shot to fame a few months ago when UC Davis graduate student Eric Lo Presti pointed out in a blog post that cycles in the caterpillar population tracked with the fortunes of political parties in presidential election years. Going back as far as 1984, Democrats won the White House in years when the caterpillars were abundant in March, and Republicans when the caterpillars were less prolific.

On October 5th, two scientists from the UC Davis Museum of Wildlife and Fish Biology joined a multi-national team of researchers to conduct biodiversity surveys on the island of New Britain, Papua New Guinea.

The expedition is coordinated by Allen Allison, senior zoologist at the Bishop Museum in Honolulu, Hawaii. Allison obtained his B.S and Ph.D. from UC Davis and has organized and led numerous research expeditions over the past 40 years in Papua New Guinea.

Plants imported into the United States sometimes hold more than leaves and stems. They also can transport hidden, non-native pests and pathogens that can cause substantial ecological and economic damage if they establish in the environment.
Pests, such as this citrus long horned beetle, can be accidentally imported in cross-border shipments of live plants. (Wikipedia)
In the United States, that pathway is growing. Over the past four decades, the dollar value of imported plants has grown at 68 percent per decade. One means of reducing their entry is to inspect live plant imports at the U.S. border.

Developing nations particularly at risk

With the increasing pace of globalization comes the movement of invasive non-native species around the planet. Although often seen as a “first-world problem,” a new study shows these invasions threaten the economies and livelihoods of residents in some of the world’s poorest nations.
