BANBURY, B.L.*; BUCHHOLZ, K.; MAGLIA, A.M.; University of Missouri-Rolla; University of Missouri-Rolla; University of Missouri-Rolla: Morphometric analyses of cranial development in pelobatid frogs The developmental osteology of pelobatid frogs (Anura: Pelobatidae) has been the subject of several studies. Despite this, little is known about the cause of the extreme variation in degree of adult cranial […]

CYR, N.E.*; ROMERO, L.M.; Tufts Univ.; Tufts Univ.: Molt Alters the Avian Cardiovascular Stress Response Basal and stress induced heart rate (HR) and Corticosterone (B) were monitored in 8 captive European starlings, Sturnus vulgaris, during and following a prebasic molt. Throughout a 24hour period basal HR was significantly higher in molting birds, potentially reflecting a […]

BURNETTE, A.; HALANYCH, K.M.; Auburn Univ.; Auburn Univ.: Molecular phylogenetic analysis of the Flabelligeridae (Polychaeta) Flabelligeridae is a group of benthic mud-dwelling polychaetes known for the modified chaetae that form the cephalic cage found in most species. There are 14 recognized genera, with most of the approximately 126 species in the genera Pherusa, Brada, and […]

KNOWLES, J.; WENINK, E.; ORTOLANO, R.; REKHI, N.; HOCK, A.; SCHULT, N.; TUNNICLIFFE, V.; MCHUGH, D.; Colgate University; Colgate University; Colgate University; Colgate University; Colgate University; Colgate University; University of Victoria, Canada; Colgate University: Molecular analyses indicate gene flow among populations of Paralvinella pandorae, a polychaete annelid endemic to hydrothermal vents of the northeast Pacific. […]

KOROBOV, Natasha; DUMONT, Elizabeth; University of Massachusetts; University of Massachusetts: Modeling Bite Force Production: A Comparative Analysis within Chiroptera It has been hypothesized that the morphology of the masticatory apparatus in mammals is constrained by the need to avoid dislocation of the temporomandibular joint (TMJ). This idea has formed the basis of several models of […]

PATEL, S.B.; WOHLEGEMUTH, S.E.; JULIAN, D.; University of Florida, Gainesville: Mitochondrial injury induced by sulfide exposure in coelomyocytes from a sulfide-adapted marine invertebrate. Exposure of animal cells to hydrogen sulfide (H2S) causes rapid cell death, but the mechanisms of toxicity are not completely known. Since H2S and cyanide both inhibit cytochrome c oxidase, the final […]

LOUIE, Kristina D.; JACOBS, David K.; Univ. of California, Los Angeles; Univ. of California, Los Angeles: Microevolution in the sea: Genetic structure in the Eastern Pacific eelgrass limpet Tectura depicta (Lottidae: Patellogastropoda) We examined the population structure of the Eastern Pacific eelgrass limpet (Tectura depicta) from Monterey Bay, CA to San Quintin Bay, Baja CA, […]

LEARY, C.J.*; KNAPP, R.; University of Oklahoma; University of Oklahoma: Mating Tactic Expression and Selection of Hosts by Satellite Male Toads: Vocal and Hormonal Relationships Alternative non-calling “satellite” tactics are adopted by males of numerous anuran species (frogs and toads), but the underlying physiological mechanisms mediating the behavioral response are poorly understood. Our research on […]

GONZALEZ, T.; HAZARD , L.C.; SINERVO, B.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz: Maternal effects on predator avoidance behaviors of hatchling side-blotched lizards (Uta stansburiana) Maternal effects can have profound influences on offspring phenotype and survivorship. Female side blotched lizards (Uta stansburiana) have the ability to […]

HUMFELD, Sarah C; University of Missouri-Columbia: Male-male competition mediates the mating tactic switch in Hyla cinerea An important example of phenotypic variation is alternative behaviors used for mate acquisition. Alternative reproductive behaviors are usually considered to be a consequence of male-male competition for a limited number of females, in which only a subset of males […]
