Onja Razafindratsima, a graduate student at Rice University, observes a lemur in a Madagascar rainforest. Razafindratsima led a three-year study to explore the relationship between lemurs and trees. Lemurs eat the fruit and spread its seeds far from the parent tree. Credit, Onja Razafindratsima/Rice University. When polar bears meet glaucous gulls over the remains of a bowhead whale, they may be sharing more than a meal. As the warming climate brings animals into new proximity, parasites, viruses, and bacteria can find opportunities to spread to new and naïve hosts, sometimes jumping from birds to mammals, and from marine ecosystems to land ecosystems.
