Don't go chasing the ghosts of the past: habitat selection and site fidelity during calving in an Arctic ungulate
Predator avoidance and food availability are both factors known to influence habitat selection and site fidelity around calving in caribou and reindeer. Here, we assess habitat selection and site fidelity during the calving period in the solitary, Arctic Svalbard reindeer Rangifer tarandus platyrhyn...
