ELNITSKY, Michael A.; LAYNE, JR., Jack R.; Slippery Rock University, PA: Effect of Tissue Freezing on Hemolymph Potassium Concentration in Gallfly Larvae. Larvae of the goldenrod gallfly (Eurosta solidaginis) are tolerant of extensive tissue ice formation, facilitating their survival of the winter microclimate that prevails in their hibernacula (ball galls on goldenrod plants). These insects […]

LESTER, O*; WALKER, JA; Utah State University, Logan; University of Southern Maine, Portland: Does the Action of Multiple Fins Improve Boxfish Turning Performance? Boxfish have both an exceptional ability to precision maneuver (turn with zero turning radius) and highly derived median and caudal fin anatomy. Throughout sharp turns, the pectoral and median fins continually oscillate, […]

WICKMAN, K.L.*; GIBB, A.C.; St. Norbert College, De Pere, WI; Northern Arizona University, Flagstaff: Does parallel evolution of upper jaw protrusion result in similar prey capture kinematics? A comparative study of Danio rerio and Betta splendens Upper jaw protrusion, an extension of the mouth during suction feeding, is hypothesized to improve prey capture performance and, […]

D.; MONTGOMERIE, R.; Queen’s University; Queen’s University; Queen’s University; Queen’s University; Queen’s University: Do sneaker male bluegill sunfish produce physiologically superior sperm? Sexually mature male bluegill sunfish (Lepomis macrochirus) display two distinct life histories. Some individuals delay reproduction until ca. 7 years of age, build […]

YANG, T.; BUFFENSTEIN, R.; O’CONNOR, T. P.; City College of New York; City College of New York; City College of New York: Disparate Age Effects On Gastrointestinal Enzymes In Naked Mole Rats Aging is accompanied by declines in all physiological processes, including gastrointestinal (GI) function. Rats and mice for example, show age-related declines in both […]

SEWALL, K.B.; HAHN, T.P.; University of California, Davis; University of California, Davis: Differential Heterospecific Mimicry in Three Species of Cardueline Finches Vocal mimicry has been documented in a number of oscine taxa. However, the prevalence and function of heterospecific mimicry in bird song remain unclear. We sampled songs from 15 individuals each of three Cardueline […]

WILLIAMS, J.L.; BIESIOT, P.M.; LEE, C.E.; Univ. of Southern Miss. Gulf Coast; Univ. of Southern Miss. Hattiesburg; Univ. of Wisconsin-Madison: Differences in Lipid Composition of Three Populations of Eurytemora affinis Reared Under Constant Conditions This study examined effects of constant rearing conditions on lipid composition of the copepod Eurytemora affinis (Poppe). Populations of different latitude […]

CATTERFELD, G.E.; DUTTO, D.J.; WICKLER, S.J.; HOYT, D.F.; California State Polytechnic University, Pomona: Deviant Forces in Trotting Horses Previous kinematic studies in horses, which normally trotted from 1.8 to ca. 5.0 m/s, suggested there might be deviations from the trends of forces and impulses seen at higher trotting speeds when speed decreased below 2.5 m/s. […]

MOUSTAKAS, J.E.; University of California, Berkeley: Developmental genetics of dermal ossifications in turtles and alligators Developmental genetics has provided us new ways to investigate homology. We can more fully understand the level of homology being addressed by using other lines of evidence to test our hypotheses. The example I have chosen to investigate is the […]
