Hunting mode and habitat selection mediate the success of human hunters

Authors: Kaitlyn M. Gaynor, Alex McInturff, Briana L. Abrahms, Alison M. Smith & Justin S. BrasharesJournal: Movement EcologyDOI: https://doi.org/10.1186/s40462-024-00471-z Abstract Excerpt: “Our study indicates that hunters can successfully employ a diversity of harvest strategies, and that hunting success is mediated by the interacting effects of hunting mode and landscape features. Such results highlight the breadth of human hunting modes, even

Sex-specific migratory behavior in a marine predator results in higher risks to females

Protecting migratory animals is challenging because males and females can travel to different places at different times of the year. In this study, Dr. Ginger Rebstock and Dr. Dee Boersma tracked male and female Magellanic penguins during their migration and found that females stayed closer to shore and slightly farther north than males. Both sexes reached similar overall latitudes, but
