ROMMEL, S.A.*; PABST, D.A.; MCLELLAN, W.A.: Convergent evolution in the vascular systems of three marine mammals Conservation of thermal energy in aquatic mammals is essential for the maintenance of high core temperatures in a heat conducting aquatic environment. Seals, dolphins, and manatees have gross morphological adaptations such as large size, modification of appendages, and blubber […]

TUBERTY, S.R.: Effects of the insect juvenile hormone agonist, methoprene, on female growth and reproduction in the Gulf sand fiddler crab, Uca panacea. Adult Uca panacea were distributed randomly (250 females, 100 males per pond) into six estuarine ponds in order to determine the effects of field applications of methoprene (Altosid� XR briquets) on female […]

DOHM, M.R.*; MAUTZ, W.J.: Effects of ozone on marine toad thermoregulatory behavior and immune function Ozone (O3) is a common air pollutant in many urban settings, and in the adjacent wildlife habitats, O3 levels frequently exceed the U.S. federal standard of 0.12 ppm. Ozone is a strong pulmonary irritant and causes a suite of thermoregulatory, […]

SCHOENFUSS, H.L.*; MARTINOVIC, D.; SORENSEN, P.W.: Effects of Water-Borne 17b-Estradiol on Reproductive Fitness in Two Species of Fish To assess the effects of endocrine disrupters on the reproductive health of male fish, we exposed male goldfish (a substrate spawner) and fathead minnows (a nest guarding species) to waterborne estradiol at a concentration found in some […]

LOVE, O.P.; SHUTT, L.; BIRD, D.M.: Dietary PCB-induced impairment of the adrenocortical response in captive American kestrels We examined the effects of dietary exposure to PCBs on the adrenocortical response in American kestrels (Falco sparverius). Nine captive male American kestrels previously exposed to elevated levels of a mixture of PCB congeners (1248:1254:1260; 1:1:1) in their […]

POWELL, M. L.; SOWER, S. A.; Univ. of New Hampshire, Durham: The Identification of Corpus Luteum and Determination of Reproductive Steroids in the Gonad of the Atlantic Hagfish, Myxine glutinosa Hagfish are considered the earliest extant vertebrates. Despite their evolutionary importance little is known about their life history or reproduction. To better understand reproduction in […]
