YOUNG, J.W.; Stony Brook University: Mechanical and Ecological Pressures on Muscle Lever Arm Growth in Primates To offset well-established volume/area relationships limiting muscle force, larger animals walk on extended limbs and show allometric increases in extensor muscle lever arm lengths. However, this pattern might not apply to ontogenetic increases in size. Although immature animals have […]

KEMP, T/J; BACHUS, K/N; NAIRN, J/A; CARRIER, D/R*; University of Utah; University of Utah; University of Utah; University of Utah: Mechanical Properties of Limb Bones in Dogs Specialized for Running Versus Fighting Anatomical and physiological specialization for fighting has been suggested to conflict with specialization for rapid and/or economical running. Such a tradeoff may exist […]

WANG, G.; HUEY, R. B.; RAINWATER, S.; Unv. of Washington, Seattle; Unv. of Washington, Seattle; Ingelmoor High School, Kenmore: Maximum Voluntary Temperature of Drosophila sp. Larvae Temperature has a large effect on larval development time and ultimate adult size in Drosophila sp., and extreme temperatures can be damaging or even lethal. Thus the body temperatures […]

TSENG, Jack; PATEK, Sheila; University of California, Berkeley; University of California, Berkeley: Looking for trouble: strike response to conspecific body colors in the peacock mantis shrimp Peacock mantis shrimp (Odontodactylus scyllarus) are spectacularly colored, with particular body regions also reflecting polarized light. In addition, they have potent raptorial appendages, with which they produce extremely fast […]

REITZEL, Adam M; SULLIVAN, James C.; FINNERTY, John R.; Boston University; Boston University; Boston University: Life History and Population Dynamics of a Parasitic Sea Anemone, Edwardsiella lineata Edwardsiella lineata, a species of burrowing anemone in the Family Edwardsiidae, displays a unique life history where the larvae selectively infect then parasitize adult ctenophores from the species […]

E.; Santa Clara Univ.; Sonoma State Univ.; Santa Clara Univ.; Sonoma State Univ.: Is color pattern variation in California willow beetles the result of temperature adaptation? We examined effects of environmental and rearing temperature on color pattern variation in the California leaf beetles Chrysomela […]

DEVICHE, P.J.*; GREINER, E.; Arizona St. Univ.; U. Florida Gainesville: Interspecific differences in hematozoan infection in Sonoran desert Aimophila sparrows We used stained thin blood smears to measure parasite infection prevalence in four conspecific grassland Aimophila sparrows: Rufous-winged (A. carpalis; RWSP), Rufous-crowned (A. ruficeps, RCSP), Cassin�s (A. cassinii, CASP), and Botteri�s (A. botterii, BOSP) sparrows. […]

Previous reports have documented seasonal clutch differences in yolk hormone levels, […]

ORTMAN, B.D.; BUCKLIN, A.; University of New Hampshire, Durham; University of New Hampshire, Durham: Integration of morphological and molecular characters to facilitate species identification and biodiversity within the Ctenophora Ctenophores, like other gelatinous zooplankton, are problematic organisms to identify using morphological characters. Their fragility makes collection of intact specimens difficult. The integration of molecular data […]
