First stop: the sea otter exhibit, followed by a short trek outside to the viewing deck with hopes of spotting wild sea otters bobbing out on the ocean’s edge. There’s just something intrinsically joyous about these curious and playful sea creatures. I could watch them for hours.

I wasn’t able to make a trip to the aquarium for , which runs through Saturday. But I did learn something new about sea otters — specifically that they are not immune to land-based disease — right here at �°������ϲ���Ļ��Ϣ Davis.

Viruses, bacteria and parasites that you’d typically associate with humans and pet cats are reaching sea otters and other marine mammals along the coast of California, with fatal results. A recent study led by the found that coastal development and climate change can accelerate the flow of disease-causing pathogens from land to sea.

“The way we develop our urban and rural coastlines — adding people, domestic animals, and hard surfaces like concrete and asphalt — can increase the flow of these pathogens into estuaries and oceans.” — Elizabeth VanWormer, lead author and a postdoctoral researcher at �°������ϲ���Ļ��Ϣ Davis at the time of the study
