The goal of this study was to observe the foraging behavior of Eastern Gray Squirrels (Sciurus carolinensis) on the University of Maine campus. The study tested whether squirrels in a more urban setting followed the optimal foraging theory, or if rarity of a food type played a greater factor in food selection. The study also examined whether urban squirrel behavior mimicked that of wild squirrels when presented with a food type uncommon on campus, but common in other parts of Maine, specifically the acorns of the white oak tree (Quercus alba). In three different areas on the campus, squirrels were …

Marsupials are a group of mammals that give birth to young that are not fully developed. These offspring must complete the remainder of their development outside of the womb attached to their mother’s teat. Marsupials only occur in South America and Australasia, with one species extending into North America. The marsupial known as the monito del monte, which is Spanish for ‘little monkey of the mountain,’ (Dromiciops gliroides) is a South American marsupial; however, it shares a key morphological feature of ankle bone morphology with Australasian marsupials. This shared, derived trait is what defines the cohort Australidelphia, to which the …
