Assessment of the Effect of Urbanization on Diversity, Population Dynamics and Wildlife Interactions Using Citizen-science Camera Trapping and Ancillary Data. AW Parsons - 2020

Overall, I found that diversity, the frequency of interspecific interactions and prey population dynamics can all be higher in suburban areas...

Behavioral response of white‐tailed deer to coyote predation risk WD Gulsby, MJ Cherry, JT Johnson, LM Conner… - Ecosphere, 2018, Georgia
... Coyote abundance (i.e., predation risk) varied spatiotemporally and was a predictor of foraging behavior during at least one season for all sex‐age classes of deer except juveniles. Adult males were more sensitive to predation risk in winter, after the breeding season, whereas adult females were sensitive to predation risk during both seasons, but more so during fall when offspring are at greater risk. Yearling males were more sensitive to predation risk than adult males, and juveniles were least sensitive to predation risk, likely because of inexperience and high energetic demands...
White‐tailed deer population dynamics and adult female survival in the presence of a novel predator MC Chitwood, MA Lashley, JC Kilgo, CE Moorman… - The Journal of Wildlife …, 2015 North Carolina
... Recent localized declines in white-tailed deer (Odocoileus virginianus) populations in the southeastern United States have been linked to increasing predation pressure from coyotes (Canis latrans), a novel predator to the region. Studies have documented coyotes as the leading cause of mortality for neonates, and 1 study documented coyotes as a mortality factor for adult females... Our data indicate that for low-density deer populations with heavy predation pressure on neonates, protecting adult females from harvest may not completely offset population declines. Coyote removal might be a necessary strategy because it could possibly increase very low fawn survival, which appears to be the most important vital rate influencing λ in our study. However, managers may have to start with reductions in adult female harvest ...
Scale-Dependent Effects of Coyote-Predation Risk on Patterns of White-Tailed Deer Browsing along Linear Forest Edges JLB Pierce, SA Dalinsky, AA Chenaille, LM Lolya… - Northeastern Naturalist, New York, 2015
... Predation can influence patterns of browse through decreasing White-tailed Deer abundance and influencing patterns of habitat selection... We did not observe a change in White-tailed Deer browsing at the landscape scale in response to variation in the risk of Coyote predation, or a mitigating role of escape cover. However, we did detect a tendency for White-tailed Deer to shift browsing from the forest edge to interior along transects with more Coyotes. Our study indicates that Coyotes in the focal area were likely influencing patterns of browsing primarily through behaviorally mediated indirect effects...
