ROMERO, L. Michael*; WIKELSKI, Martin; Tufts University; Princeton University: Daily Differences in the Capacity of Marine Iguanas to Respond to Stress Recent data indicate that Galapagos marine iguanas (Amblyrhynchus cristatus) exhibit a distinct diel cycle in corticosterone release. Corticosterone concentrations are approximately twice as high in the day than at night. We tested whether lower […]

SANFORD, Christopher P.; Hofstra University: Comparative kinematic analysis of a novel feeding mechanism in salmonid fishes Salmonid fishes possess a novel feeding mechanism that involves structural modification of the hyoid system. This tongue-bite apparatus of salmonids consists of a set of well-developed teeth on the dorsal surface of the anterior hyoid region (basihyal) and an […]
