An Ecological Niche Model To Predict Range Expansion Of The Eastern Gray Squirrel In California, Carly M. Creley, Alan Muchlinski, Fraser Shilling

Bulletin of the Southern California Academy of Sciences

The eastern gray squirrel, Sciurus carolinensis (EGS) has been introduced to California and has expanded its geographic range since initial introductions. In this study we projected the potential future geographic range of the EGS in California using Maxent to create an ecological niche model. Location data were obtained over the time period of 2004 - 2015 from museum specimens, wildlife rehabilitation centers, the California Department of Public Health, the California Roadkill Observation System, and non-iNaturalist citizen science observations. Research grade data from iNaturalist was obtained over the time period of 2004 - 2018. Range and habitat suitability maps were developed by mapping ...
