Scientists have linked the decline in Arctic sea ice to the emergence of a deadly virus that could threaten marine mammals in the North Pacific, according to a study from the University of California, Davis.

The sixth ebolavirus, Bombali virus, has been detected in insect-eating bats in Guinea. The discovery of Bombali virus first in insect-eating bats in Sierra Leone, and now in Guinea, marks the first time that scientists discovered a new ebolavirus species in a host before detection in an infected human or sick animal.

UC Davis scientists have pinpointed specific strains of the parasite Toxoplasma gondii that are killing southern sea otters, tracing them back to a bobcat and feral domestic cats from nearby watersheds.

An article in Salon describes how scientists over the last couple decades have compiled evidence that cat feces, which often drains into the ocean in coastal cities, can infect Hawaiian monk seals with toxoplasmosis — a potentially fatal disease caused by a single-cell parasite.
