🚨 Paper Alert 🚨

Second PhD paper is out in Movement Ecology!

What the surprising lives of solitary animals reveal about us A new understanding of why some animals evolved to be loners, and the benefits that brings, shows that a social lifestyle isn’t necessarily superior

Great to see the feature on the social behaviour of solitary animals being released by #NewScientist #SamWong!

The feature also includes a short section regarding the findings of my first PhD paper. #brownbears #social #solitary #animals #science #wildlife
