A collaborative study with a CU Boulder professor investigates how the risks and rewards of red squirrel reproduction is a microcosm of evolutionary patterns You’ve probably seen plenty of squirrels ...

In a five-year study of red squirrels in a jack pine (Pinus banksiana) forest in central Alberta, Canada, the probability of primiparity (i.e. producing a litter for the first time) was correlated ...
