Predicting Range Shifts For The Virginia Opossum In Maine, Sara Griffin
Predicting Range Shifts For The Virginia Opossum In Maine, Sara Griffin
Honors College
Species distribution and movement are increasingly influenced by climate change and human expansion. The Virginia opossum (Didelphis virginiana) has been observed expanding their range northward due to the warming temperatures and urbanization. The Virginia opossums’ northern range is thought to be restricted by two abiotic winter factors, snow cover and low temperatures, which prevents foraging and ultimately leads to starvation. For this study, I predicted the movement of the Virginia opossum northward into central Maine and beyond based on current climate change trends. Microclimate temperatures were recorded using data-loggers and climate variable datasets were used to determine if …
