AMES, C.E.; WILLIAMS, T.D. *; VEZINA, F.; Simon Fraser University, Burnaby; Simon Fraser University, Burnaby; Simon Fraser University, Burnaby: Rapid regression of a still-functioning linear organ: the avian oviduct. Egg production in oviparous vertebrates is widely assumed to be costly but the physiological basis of any costs remains unknown. Previously we have shown that, a) […]

BUTCHER, M.T.*; BERTRAM, J.E.A.; BENZUIDENHOUT, A.J.; Florida State University, Tallahassee; Florida State University, Tallahassee; College of Veterinary Medicine, Cornell University, Ithaca, NY: Putative role of the collateral ligaments of the distal sesamoid bone in Equus The distal forelimb of the horse displays a complexity of ancillary ligaments. For some of these the function is known, […]

GIFONDORWA, D.J.; LEISE, E.M.; Univ. of North Carolina Greensboro; Univ. of North Carolina Greensboro: Programmed Cell Death is Inhibited by Nitric Oxide in the Apical Ganglion during the Metamorphosis of the Marine Mollusc Ilyanassa obsoleta The central nervous system of a competent larva of Ilyanassa obsoleta contains an unpaired apical ganglion (AG) of approximately 25 […]

KNOTT, K.K.; BARBOZA, P.S.; BLAKE, J.E.; University of Alaska, Fairbanks: Postnatal development of two arctic ruminants Young reindeer (Rangifer tarandus) and muskoxen (Ovibos moschatus) transition from milk to forage over a short summer at high latitudes. Digestive and metabolic systems must develop quickly to support the dietary transition and establish tissues for winter. We hypothesized […]

DORNER, M.A.*; COFFROTH, M.A.; MAY, G.E.; University at Buffalo, NY; University at Buffalo, NY; University of Wisconsin, Madison: Possible sources for symbiont variation within the genus Aiptasia over time and space Sea anemones within the genus Aiptasia are distributed worldwide and typically harbor symbiotic dinoflagellates. Aiptasia collected from Japan (A. pulchella), Hawaii (A. pulchella), Eilat […]

CHRISTENSEN, A.B. *; DEAN, D.K.; Lamar University; Lamar University: Population structure in a fissiparous ophiactid brittlestar possessing hemoglobin A small fissiparous brittle star, belonging to family Ophiactidae, was collected from South Jetty, Port Aransas, TX. While it was found in a variety of sponge and algal species, the densest aggregations were found in the colonial […]

HAZARD, L.C.*; SINERVO, B.; MILLER, J.; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz: Physiological performance and predator avoidance behaviors of hatchling side-blotched lizards (Uta stansburiana) Predator avoidance is one of the important determinants of survival, and ultimately of fitness. Antipredator behaviors and color patterns of reptiles may […]

STRUCK, T.H.; PURSCHKE, G.; University of Osnabr�ck, Germany; University of Osnabr�ck, Germany: Phylogenetic relationships of small and enigmatic polychaetes based on 18S-rDNA sequences The phylogeny of meiofaunal polychaetes based on morphological data is controversially discussed due to their great simplicity. These species often lack characters typical of larger polychaetes, such as parapodia and head appendages, […]

CONSTABLE, H.; MOOI, R.*; California Academy of Sciences, San Francisco; California Academy of Sciences, San Francisco: Phylogenetic analysis of echinothurioids, deep-sea echinoids with venomous spines Echinothurioids are strange, “regular” sea urchins having features indicative of a basal position in the phylogeny of extant echinoids. A few echinothurioids live on coral reefs, but the vast majority […]
