Raccoon Acclimation Towards Traps and its Effect on Surveillance and Monitoring of Zoonotic Diseases
<p>Raccoons (Procyon lotor) serve as a source of infection with various pathogens for people, most notably, rabies. Raccoons are specifically targeted for the control of rabies in the United States, primarily due to the 100% fatality rate in humans and animals. There is no cure or treatment for …

Cascading Effects Of Predator Removal On The Ecology Of Sea Turtle Nesting Beaches
… of egg mortality for sea turtles in Florida and raccoons are intraguild predators of ghost crabs. Because of the damage done to sea turtle nests, raccoons have been removed from some beaches during the sea turtle nesting season. I compared the diet and demography of a raccoon population that had …
