Meeting Abstract P3.72  Saturday, Jan. 5  Modeling interaction between Mauthner cells and central pattern generators HO, L L*; KUNEC, S; ROOT, R G; Lafayette College; Worcester State College; Lafayette College robroot@lafayette.edu Mauthner cells initiate the fast-start response to threatening stimuli in fish. This response requires abrupt reactions from neurons comprising the central pattern generator (CPG). We offer […]

Meeting Abstract P3.58  Saturday, Jan. 5  Maximum running speed in mammals is inversely correlated with a proxy for male-male competition. CARRIER, David/R; Univ. of Utah carrier@biology.utah.edu The physical demands of rapid and economical locomotion differ from the demands of aggressive behavior in ways that may prevent simultaneous evolution of optimal performance in both behaviors. In this analysis, […]

Meeting Abstract P3.49  Saturday, Jan. 5  Locomotive function of the anal fin in boxfishes WOOLARD, A.M.*; BARTOL, I.K.; Old Dominion University; Old Dominion University awool006@odu.edu Boxfishes (Teleostei: Ostraciidae) are remarkably stable and maneuverable rigid-bodied swimmers, relying predominantly on complex motions of their median and paired fins for propulsion over most of their speed range. Recent studies have […]

Meeting Abstract P3.121  Saturday, Jan. 5  Life in the Big City: Thermal Tolerance of Isopods to Urban Heat Islands COOPER, B.S.; WILLIAMS, B.H.*; ANGILLETTA, M..J.; Indiana State University, Terre Haute; Indiana State University, Terre Haute; Indiana State University, Terre Haute bwilliams27@mymail.indstate.edu Urbanization has led to rapid heating of local environments, potentially creating new selective pressures for organisms […]

Meeting Abstract P3.119  Saturday, Jan. 5  Larval settlement in benthic environments: The effects of velocity and bed geometry FINGERUT, J.T.*; THOMSON, J.R.; HART, D.D.; Saint Joseph’s University; Monash University, Australia; University of Maine jfingeru@sju.edu Many benthic invertebrates have complex life cycles in which dispersal processes play a critical role in determining patterns of distribution and abundance. Near-bed […]

Meeting Abstract P3.101  Saturday, Jan. 5  Kisspeptin-like immunoreactive neuron distribution in green treefrogs (Hyla cinerea) LUTTERSCHMIDT, D.I.*; WILCZYNSKI, W.; Georgia State Univ., Atlanta; Georgia State Univ., Atlanta Lutterschmidt@gsu.edu Kisspeptins, a family of neuropeptides encoded by the KiSS-1 gene, promote the secretion of gonadotropin-releasing hormone (GnRH) and are endogenous ligands for the G protein-coupled receptor GPR54. In mammals, […]

Meeting Abstract P3.86  Saturday, Jan. 5  Isolated fish gills as a model for teaching osmotic permeability to undergraduate physiology students. FURIMSKY, M.*; ROBERTSON, J.; Westminster College, Pennsylvania; Westminster College, Pennsylvania furimsmm@westminster.edu The fish gill represents an important interface between the organism and its external aquatic environment and is an excellent model that undergraduate physiology students can use […]

Meeting Abstract P3.79  Saturday, Jan. 5  �Influences of incubation humidity on development and function of kidney in the chicken, Gallus gallus domesticus.� BOLIN, GM*; BURGGREN, WW; University of North Texas; University of North Texas greta_bolin@hotmail.com Embryological development in avian species is influenced by a number of environmental factors, most notably temperature and humidity. Under normal conditions the […]

Meeting Abstract P3.41  Saturday, Jan. 5  Induction of Collagenase Activities by 20-Hydroxyecdysone in the Epidermis of the Fiddler Crab, Uca pugilator TOUPS, E.*; ZOU, E.; Nicholls State University; Nicholls State University toupe208@its.nicholls.edu Crustaceans are limited to discontinuous growth due to their rigid exoskeleton. In order to grow they must shed their exoskeleton periodically. The crustacean exoskeleton is […]
