WATTS, Philip; FISH, Frank E.; Applied Fluids Engineering, Inc.; West Chester University: Fluid Dynamic and Maneuverability Aspects of Humpback Whale Flippers Humpback whales capture prey through tight maneuvers, and their flippers appear to be an integral part of these maneuvers. Humpback whales possess tubercles on the leading edges of their high aspect ratio flippers. Our […]

FISH, F.E.; KETTEN, D.R.; West Chester Univ., PA; Woods Hole Oceanographic Institution: Examination of three-dimensional geometry of cetacean flukes using CT-scans The flukes of cetaceans function in the hydrodynamic generation of forces for thrust, stability, and maneuverability. The three-dimensional geometry of flukes is associated with the production of lift and drag. Previous studies of fluke […]

BUNKERS, J L; GOMES, F; REZENDE, E L; SALTZMAN, W; GARLAND, T Jr; Univ. of California, Riverside: Plasma Corticosterone of Mice Selectively Bred for High Voluntary Wheel Running: Levels at Rest and Following Restraint Stress The hypothalamic-pituitary-adrenal (HPA) axis is important in regulating energy metabolism and mediates responses to a broad range of stressors. Glucocorticoids […]

DERRICKSON, E.M.; Loyola College: Maternal protein intake during pregnancy and lactation determines milk composition in Mus musculus Both the quantity and quality of resources available to mammals can strongly influence growth and development of juveniles during the lactation period. Although the quantity of food has demonstrated effects on lactation and reproductive success, the effect of […]

OUFIERO, C.E.*; ANGILLETTA, M.J.; Indiana State Univ., Terre Haute: It�s not just the size; it�s what�s inside that counts: Female size, egg size, and egg composition in the lizard Sceloporus undulatus. Morphological constraints are thought to produce non-adaptive variation in egg size. For example, the size of a female�s pelvis may force her to produce […]

MARTIN, LB*; HASSELQUIST, D; WIKELSKI, MC; Princeton University; Lund University; Princeton University: Immune function complements life history in tropical and temperate House Sparrows Tropical passerine birds often lay small clutches, have long embryonic developmental periods, and high adult survival rates compared to related temperate species. Many ecological factors, particularly nest predation and food availability, have […]

HAZARD, L.C.*; NAGY, K.A.; MILES, D.; COSTA, D.; SINERVO, B.; Univ. of California, Santa Cruz; Univ. of California, Los Angeles; Ohio University; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz: Field metabolic rate, stamina and survival of male lizards with alternative mating strategies Male side-blotched lizards (Uta stansburiana) in Los Banos, CA exhibit […]

MCLISTER, JD; DEARING, MD; University of Utah; University of Utah: Differences in juniper consumption among woodrat species is related to different rates of phase I biotransformation Herbivores may evolve the ability to consume a toxic plant either by developing specialized biotransformation pathways to deal with the secondary compounds specific to that plant (i.e., qualitative) or […]

HALEY, S*; DEARING, M.D.; University of Utah: Detoxification of plant secondary compounds by woodrat herbivores, genus Neotoma. Mammalian herbivores routinely consume diets laden with toxins, yet the way in which wild herbivores detoxify plant secondary compounds is largely unknown. We took a pharmacological approach to understanding how a specialist (Neotoma stephensi) and generalist (Neotoma albigula) […]

ULRICH, Paul N.*; MARSH, Adam G.; University of Delaware; University of Delaware: Tissue-specific differences and interindividual variation of malate dehydrogenase activity and protein content in the oyster Crassostrea virginica Malate dehydrogenases (MDH, mitochondrial and cytosolic) are integral to bivalve metabolism with particular importance during anaerobiosis. We found that the specific activities of heart and phasic […]
