Ecological destruction fuels emerging diseases
...e destruction of habitat by human activity and the extinction of species around the world is more than a looming environmental catastrophe, warns a Canadian zoologist. This ecological damage also endangers human health by turning parasites into "evolutionary land mines." Dr. Daniel (Dan) Brooks, a parasitologi......survive, Smith speculates that substantial species extinction may have occurred in the whale fall fauna. “The deep ocean appears to be a major reservoir of biodiversity on the planet. Some of the oddest animals ever discovered occur on whale falls,?says Smith. “These communities are the undertakers of the deep,...Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...sion, a host can be rescued from pathogen-mediated extinction by the presence of a second host with which it shares a pathogen. Sharing a pathogen among one or more alternative species may actually be limiting the spread of the pathogen in any one particular host population. Thus, an epidemic on one species may...Great White shark evolution debate involves WSU Lake Campus geology professor
