New research from the University of California, Santa Cruz shows how regional shelter-in-place orders during the coronavirus pandemic emboldened local pumas to use habitats they would normally avoid due to their fear of humans. This study, published in the journal Current Biology, is part of a growing wave of research working to formally document the types of unusual changes to wildlife movements and behaviors that people around the world reported during pandemic lockdowns.
Golden jackals, for example, were spotted foraging in broad daylight in urban Tel Aviv, Israel, and mountain lions were seen strolling through downtown Santiago, Chile. Urban environments had suddenly become quiet and empty as shelter-in-place orders brought human movement to a grinding halt—an effect some researchers have called the “anthropause.” Wildlife seemed to be taking advantage. The new study shows this was certainly true for pumas in the Santa Cruz Mountains. Researchers were able to clearly connect changes in the cats’ habitat use with reduced human mobility during shelter-in-place orders.
Chris Wilmers, an environmental studies professor at UC Santa Cruz, led this research. Wilmers is the principal investigator for the Santa Cruz Puma Project, and he has been studying local mountain lion populations for over a decade. In particular, his research uses data from GPS tracking collars placed on wild pumas to show how fear of humans affects mountain lion behavior and ecology. When the pandemic hit, his team was already tracking data from several collared cats, and he recognized a unique research opportunity.
