Little mammals need speed for marathon mate-finding sessions
Male Northern quolls live fast and die young in a romantic frenzy of long-distance travel. And that’s only part of the reason why animal athletics specialist Robbie Wilson of the University of Queensland in Australia chases quolls with a plastic block.
