I worked in the scat analysis part of this as an undergrad way back when! So cool to see this work published thanks to Kate Weiss
🐇 This study presents a methodological framework using camera trap and scat data to assess how components of prey availability influence prey selection. This is done in a way that can be applied across a variety of mammal species and ecological contexts➡️ buff.ly/7iWNO4X

This crucially important and obviously visionary work makes me feel vindicated for having said the same thing last year, albeit with much less evidence, while being mercilessly mocked by the city and its residents. royalsocietypublishing.org/doi/10.1098/...
Rodent indent not self-evident: a case of mistaken identity of the ‘Chicago Rat Hole’ | Biology Letters
The ‘Chicago Rat Hole’ is a remarkable full body impression ostensibly created by
a brown rat (Rattus norvegicus) crossing fresh concrete in Chicago’s Roscoe Village that became a viral sensation.

So amazing our team’s work is getting recognized on @npr.org for our successful bi-national translocation of California red-legged frogs. Was super fun chatting with Nate about the project!
How do scientists monitor the populations of the threatened California red-legged frog? With careful listening and a little help from AI.
