Natal dispersal plays an important role in connecting individual animal behavior with ecological processes at all levels of biological organization. As urban environments are rapidly increasing in extent and intensity, understanding how urbanization influences these long distance movements is critical for predicting the persistence of species and communities. There is considerable variation in the movement responses of individuals within a species, some of which is attributed to behavioral plasticity which interacts with experience to produce interindividual differences in behavior. For natal dispersers, much of this experience occurs in the natal home range. Using data collected from VHF collared coyotes (Canis latrans) in the Chicago Metropolitan Area we explored the relationship between early life experience with urbanization and departure, transience, and settlement behavior. Additionally, we looked at how early life experience with urbanization influenced survival to adulthood and the likelihood of experiencing a vehicle related mortality. We found that coyotes with more developed habitat in their natal home range were more likely to disperse and tended to disperse farther than individuals with more natural habitat in their natal home range. Interestingly, our analysis produced mixed results for the relationship between natal habitat and habitat selection during settlement. Finally, we found no evidence that early life experience with urbanization influenced survival to adulthood or the likelihood of experiencing vehicular mortality. Our study provides evidence that early life exposure influences dispersal behavior; however, it remains unclear how these differences ultimately affect fitness.
Wildlife increasingly live in and adapt to urban landscapes as natural habitat becomes urbanized. Many carnivores take advantage of undeveloped or open developed areas called green spaces, such as parks or cemeteries, to meet their requirements in urban areas. For instance, coyotes (Canis latrans) expanded their range across most of North America into metropolitan areas and even within highly developed areas, where home ranges of coyotes are associated with green spaces or areas that humans used least. Golf courses are a unique type of green space within urban landscapes that can provide cover and prey for coyotes, as well as limit human presence, especially at night and during the winter off‐season. We estimated selection of golf courses and urban green spaces by coyotes within the Chicago Metropolitan Area, Illinois, USA (2009 to 2012) that had access to golf courses (home range composed of >3% golf course; n = 30) using radiotelemetry. We found that coyotes selected for golf courses more at night and during the off‐season, indicating that they were responding to the decreased human presence during this time. Spatial status (resident vs. transient) and the amount of developed land in a home range did not influence selection of golf courses. Conversely, selection of urban green spaces was greater in the summer for transients and with proportion of developed land, but not influenced by time of day. However, there was considerable intra‐ and inter‐individual variability in coyote selection of both golf courses and urban green spaces. Individual variability could be driven by coyote characteristics (i.e., prey preferences, natal habitat, or social status) or by golf course and urban green space characteristics (i.e., landscaping, golfing hours, average human occupancy, or tolerance by personnel). © 2020 The Wildlife Society.
