Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon
Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon
Murray State Theses and Dissertations
Dirofilaria immitis (canine heartworm) was found in forty-two (42) of the two hundred seventy-five (275) Canis latrans (coyote) necropsied in the state of Kentucky from November 27, 2019 through March 3, 2021. Thirty-five (35) of the positive cases were from western Kentucky region with the other seven spread across the state. With this group of coyotes, one hundred fifty-eight (158) were male and the other one hundred six-teen (116) were female. The estimated age ranged from a pup to senior dogs. A little over forty percent of the dogs were obtained through coyote/predator tournaments; the remaining were acquired from pest …
Using Stable Isotopes And Diet Analysis To Assess The Potential For Competition And Coexistence Among Coyotes (Canis Latransl, Red Foxes (Vulpes Vulpes), And Gray Foxes (Urocyon Cinereoargenteus) In Maine, Henry M. Masters
Student Scholarship
When two species compete for food, one species typically outcompetes the other. Subordinate species can alleviate costs of competition by reducing diet overlap, promoting coexistence. Non-native coyotes (Canis latrans) and historically native gray foxes (Urocyon cineroargenteus) have expanded their range in Maine and may compete with native red foxes (Vulpes vulpes). To investigate competition, I analyzed stable isotopes and stomach contents to determine if coyotes, red foxes, and gray foxes differed in use of anthropogenic foods and trophic position. I predicted that coyotes utilize anthropogenic foods the least (lowest δ13C), and red foxes utilize …
