My first #dissertation chapter has been published! The paper focuses on #predation of #urban #wildlife by #cats with recommendations for collaborative data-driven management strategies. Main points are summarized in this #infographic, but more info and paper link in this thread!
We spent 3 years surveying #WashingtonDC for #cats using #trailcams. Whenever we saw an image of a cat carrying prey, we noted the species and location, and added it to our predation database.
So what influences predation rates by #urban #feral cats? We found 2 driving factors: access to cat food and distance to forest edge. Why would cat food increase predation? Supplemental food allows cats to occur at greater densities, amplifying population-level predation!

#Bears are one of the most curious and explorative animals we capture on our #trailcams. We’ve caught them saying hello to the camera (occasionally even tilting it or knocking it down!), rearranging our bait setups, rolling and rubbing on the bait, and even mating! (1/5)
Our camera sites are set up w/ bait meant to attract the #WolverineTrackingProject’s target species, #SierraNevadaredfox, #graywolf, #Pacificmarten, & #wolverine. #Bears happen to also love this stuff, which is no surprise, given how important scent is to communication. (2/5)
Bears use a variety of methods to communicate, including leaving their own scent as well as picking up scents they like. Their scent glands are located between their shoulder blades, on the bottoms of their feet & between their toes. (3/5)
