If you've ever seen a leopard seal in a film or documentary, chances are it was viciously tearing apart a penguin.

We are different from state/national parks or other wild lands because we are part of a university, thus research and education are a focus. These sites are living laboratories for researchers and classrooms without walls for students. And because we are a system, we can address important topics like climate change ecosystem-wide.

And researchers are now finding that these unique microbial communities — called microbiomes — can greatly influence human and environmental health. The human gut microbiome alone has now been linked to allergies, inflammatory bowel disease, obesity and many other conditions.

Oct 8 2015Evolution of Kangaroo-Like Jerboas Sheds Light on Limb Development
With their tiny forelimbs and long hindlimbs and feet, jerboas are oddly proportioned creatures that look something like a pint-size cross between a kangaroo and the common mouse.
How these 33 species of desert-dwelling rodents from Northern Africa and Asia evolved their remarkable limbs over the past 50 million years from a five-toed, quadrupedal ancestor shared with the modern mouse to the three-toed bipedal jerboa is detailed in a paper published in this week's issue of the journal Current Biology.

Jul 22 2015Resolving Social Conflict Is Key to Survival of Bacterial Communities
Far from being selfish organisms whose sole purpose is to maximize their own reproduction, bacteria in large communities work for the greater good by resolving a social conflict among individuals to enhance the survival of their entire community.
It turns out that, much like human societies, bacterial communities benefit when they can balance opposing needs within the group.

Jul 07 2014Why 'Whispers' Among Bees Sometimes Evolve Into 'Shouts'
Let's say you're a bee and you've spotted a new and particularly lucrative source of nectar and pollen. What's the best way to communicate the location of this prize cache of food to the rest of your nestmates without revealing it to competitors, or "eavesdropping" spies, outside of the colony?

Apr 12 2012Studies Reveal How Cells Distinguish Between Disease-Causing and Innocuous Invaders
The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundworms by biologists at UC San Diego has uncovered some important clues to finally answering that question.
