Episode 91 Myxomatosis: Down the rabbit hole

Invasive rabbits so numerous they form a “gray blanket” across the land. A killer virus, intentionally released to keep the bunnies at bay. An ensuing evolutionary arms race with no end in sight. It sounds more like the premise of a bad sci fi movie rather than a textbook case of biocontrol. But truth, especially in this case, is stranger and even more fascinating than fiction. If this is the first you’re hearing about myxoma virus and its place in the long history of European rabbits in Australia, get ready for a gripping story filled with rabbit facts, discussions about what drives pathogens to be deadly or benign, and philosophical musings about the situational difference between pest, pet, and keystone species. That’s right, we’re heading deep down the rabbit hole with this one.
