Norepinephrine (NE), acting through alpha-2-noradrenergic receptors in the hypothalamic paraventricular nucleus (PVN), has been implicated in the control of feeding behavior and body weight gain. To determine whether this hypothalamic receptor system…
Scratches on bones have routinely been attributed to tooth marks (a predominantly untested speculation), ignoring the effects of claws, perhaps because of the general assumption that claws are too soft to damage bone. However, some pathologies…
Cetacean evolution was shaped by an extraordinary land-to-sea transition in which the ancestors of whales became fully aquatic. As part of this transition, these mammals evolved unusually thick blubber which acts as a metabolic reservoir as well as…
OBJECTIVES: Platyrrhines span two orders of magnitude in body size and are characterized by diverse feeding behaviors and diets. While size plays an important role in primate feeding behavior and masticatory apparatus morphology, we know little about…
