Understanding species responses to urbanization is key for gaining insights into
the ecology and management of wildlife in these rapidly expanding environments.
Survival is a critical process linking individual level responses to larger scale
dynamics impacting population persistence. Importantly, the resources and risks
Survival is a critical process linking individual-level responses to broader-scale
dynamics important for population persistence. Notably, the resources and risks
affecting survival in urban wildlife are in large part shaped by aspects of the
human social system which influence the distribution of resources like green space
and risks including vehicles and pollutants. We explored the effects of social
and risks like pollutants. I explored the effects of social
and environmental characteristics on survival in urban coyotes - a species of
particular management interest due to occasional attacks on domestic animals
and less frequently, humans.
particular management interest due to their conflicts with domestic animals and,
less frequently, humans.

We used data from VHF-collared coyotes. The social and environmental characteristics
experienced by the animals were determined using a landscape raster containing
geospatial data on the variables of interest (raster code:
https://github.com/zepedae/social-environmental-raster.git). The locations
characteristics were extracted using the raster package, averaged within individuals,
and then used as predictors in a Cox proportiona hazards model.
Using location data from radiocollared coyotes captured as pups and tracked as adults, I estimated
the effect of natural and disturbed habitat availability, median income, and human population density
on their survival time. Each location's characteristics were extracted using a geospatial raster (https://github.com/zepedae/social-environmental-raster.git) and the *raster* package, averaged within individuals, and then used as predictors in a Cox proportiona hazards model.

Two models were constructed. The local model uses data from the coyote's last 6 months
of life whereas the global model uses the entire set of locations.
