LILJE, K.E.; FISCHER, M.S.: Limb proportions in forelimbs of Bovidae and Cervidae Previous studies of limb bone scaling consider the relationship between forearm bones (humerus, radius, metacarpus) and body mass, or the relationships of forearm bones to each other. Studies of locomotion in small and medium-sized mammals clearly demonstrate that scapular retraction is the most […]

KOJESZEWSKI, T.B.*; FISH , F.E.: Kinematics of swimming in the Florida manatee Swimming of the Florida manatee Trichechus manatus latirostris was studied to determine the performance of an aquatic mammal using the undulatory mode.The propulsive movements of captive manatees were examined at Sea World, FL and the Lowry Park Zoo, FL.As the animals swam rectilinearly […]

HARRISON, K.D.*; ZOZZARO, P.E.; COLLIE, N.L.; CARR, J.A.: Iodide Transport in Xenopus laevis Gut and Skin Ammonium perchlorate is an important environmental contaminant found at munitions and rocket fuel waste sites. The perchlorate anion is a potent inhibitor of iodide (I–) uptake by the thyroid, thus disrupting thyroid hormone synthesis. However, there are several extrathyroidal […]

SANDHAUS, E.A.*; BLOOMSMITH, M.A.; SNYDER, R.J.; MARR, M.J.; HUANG, X.M.; MAPLE, T.L.: Intraspecific Aggression Among Socially Housed Female Giant Pandas With the wild population of giant pandas (Ailuropoda melanoleuca) in serious danger of extinction, it has become increasingly important to establish a self-sustaining captive population. However, both male and female captive giant pandas exhibit behavioral […]

VAJDA, A.M.; NORRIS, D.O.: Interactions of Gonadal steroids and Dioxin on Gonaduct growth in larval Tiger Salamanders, Ambystoma tigrinum Modulation of steroid action in response to diverse environmental cues yields potentially adaptive phenotypic diversity in reproductive characters. Exposure to environmental signals of anthropogenic origin (i.e. chemical pollutants) might interfere with steroid hormone action, yielding diverse […]

PABST, D.A.*; HARRADINE, T.M.; MCLELLAN, W.A.; BARBIERI, M.M.; MEAGHER, E.M.; SCOTT, M.D.: Infrared thermography as a tool to assess thermal function of the bottlenose dolphin (Tursiops truncatus) dorsal fin The dolphin dorsal fin is a dynamic thermal control surface. Body heat can be dissipated to the environment when blood is shunted to superficial veins and […]

BERGER, M.S.: Inducible heat-shock protein expression in two barnacle species, Balanus glandula and Balanus crenatus In the intertidal, body temperatures of sessile marine organisms can reach 25-30 °C for extended periods of time during low tide. I examined the response to thermal stress in two barnacle congeners, Balanus glandula and Balanus crenatus, by measuring (1) […]

CAIN, SD: Identified Neurons in Two Groups of Tritonia diomedea Respond Differently to an Earth-strength Magnetic Field Stimulus Behavioral and neurophysiological studies of magnetic field sensitivity have provided evidence that diverse animals possess the ability to use the geomagnetic field to guide orientation and migration behavior. One animal in which these investigations have been carried […]

UYENO, T.A.: How squids bite: the functional morphology of cephalopod beaks and mandibular muscles The cephalopod buccal mass, located at the center of the base of the arms and tentacles, contains the upper and lower beaks. Often compared to those of a parrot, the beaks perform analogous functions of manipulation and chewing food, but differ […]

SORTE, C.J.; HOFMANN, G.E.: Heat-shock protein expression in Nucella species of the Northeastern Pacific Five species of Nucella, the dog whelk, are distributed across variable latitudes, with large areas of overlap, along the North American West Coast. In addition, within a rocky intertidal site, distribution of species differs with changing wave exposure and time of […]
