They infest your brains! They control your mind and lead you to your demise! And they come from outer space!
Or at least in that general direction...
is a WERC lead scientist based at our Channel Islands Field Station and at University of California-Santa Barbara
. He has devoted much of his research to the study of parasites and their complex life cycles -- how they feed on their hosts and how they reproduce and disperse. "Parasites are organisms, too," Lafferty likes to remind us. "But they just live life a bit differently."
To get a taste of Lafferty's research, check out this archive video clip from 2009. Here, he and colleague Dr. Jenny Shaw explain their work on the brain parasite Euhaplorchis californiensis.
This parasite infest the brains of small fish in the Carpinteria Salt Marsh near Santa Barbara
. It causes a fish to swim erratically, making its host more visible to hungry, predatory birds. When the birds eat the fish and fly away to the sky, they also carry the parasites away, eventually dispersing the parasite's eggs into other ponds through their fecal matter.
