Global climate change is unequivocal, and rates of observed and predicted temperature increases are greater at higher latitudes (Intergovernmental Panel on Climate Change, 2014). High-and mid-latitude regions have experienced rapid environmental change over the past half-century, including increases in mean air and surface temperature, extreme high temperature events, decreases in the number of frost-free days, and decreases in ice cover (Bartolai et al., 2015;Cohen et al., 2014). The short post-glacial history of the Northern hemisphere mid-latitudes, combined with regional geology, climate, and varied habitat types, makes this region the

We compare diet and feeding behaviour of Snapping Turtles (Chelydra serpentina) and Midland Painted Turtles (Chrysemys picta marginata) in Algonquin Provincial Park, Ontario, Canada. We observed young Chelydra and Chrysemys turtles feeding on insect and amphibian larvae in ephemeral ponds, adult Chrysemys terrestrially foraging on odonate larvae, and adult Chelydra consuming aquatic vegetation and seeds. These and other observations highlight the importance of seasonally available habitat and food for juvenile turtles. We also discuss the evidence for, and importance of, turtles as seed-dispersal agents for aquatic vegetation. Illustrative video recordings accompany our dietary observations.
