Abstract.—We tracked Bog Turtles (Glyptemys muhlenbergii) using radio-telemetry equipment to obtain fecal samples. We analyzed fecal samples to determine the identity of food items in both northern and southern populations in New Jersey, USA. Food items identi ed included: beetles, millipedes, ants, ies, caddis y larvae, snails, and plant material, including seeds. While we found no signi cant di erences between the diets of the two populations, fecal samples from the northern population contained more millipedes, caddis fly larvae, flies, and snails. Conversely, fecal samples from the southern population contained more beetles and seeds. This work adds to the basic life-history data on Glyptemys muhlenbergii, and may be valuable to conservation e orts.
