HITCHCOCK, M.A.; MCBRAYER, L.D.; Stephen F. Austin State University; Stephen F. Austin State University: Seasonal and intraspecific variation in thermoregulation of the Mediterranean gecko (Hemidactylus turcicus) The primary objective of this study is to provide the first thorough investigation of thermoregulatory variation in a nocturnal lizard during its activity period. Since comprehensive investigations of thermoregulation […]

NYACK, A.C.; KINSEY, S.T.; University of North Carolina at Wilmington; University of North Carolina at Wilmington: Scaling of post-contractile phosphocreatine recovery in white muscle of black sea bass (Centropristus striata) Most cells do not exceed sizes of about 100 μm, presumably to maintain a high cell surface area to volume ratio (SA:V) and short intracellular […]

LEONARD, J.L.*; PEARSE, J.S.; BREUGHELMANS, K.; BACKELJAU, T.; DIEP, P.J.; ROBLES, M.; TOWNSEND, R.C.; Univ. of California, Santa Cruz; Royal Belgian Institute of Natural Sciences, Brussels: Rapid Evolution in Banana Slugs (Ariolimax spp.) (Gastropoda; Stylommatophora: Arionidae): Life History Parameters. Although the banana slugs of the west coast rain forests are superficially identical from San Diego […]

WALTHALL, J.C.; ASHLEY-ROSS, M.A.; Wake Forest University; Wake Forest University: Postcranial myology of the California newt, Taricha torosa Locomotor patterns of salamanders are of interest due to the group�s postural resemblance to primitive tetrapods. Dissection and description of the muscles of the forelimb, trunk, and hindlimb of Taricha torosa were undertaken as part of a […]

LUTTERSCHMIDT, WILLIAM I.; Sam Houston State University: Post-Prandial Thermophily in a Fossorial Snake? Many ectothermic species demonstrate behavioral thermoregulation following feeding in an attempt to increase body temperature, thus increasing temperature-dependent rate processes associated with catabolism. This increased body temperature in reptiles is usually attained heliothermically within their microhabitat by basking in direct or filtered […]

LYNCH, Kathleen S.; WILCZYNSKI, Walter; University of Texas, Austin: Plasticity in Female Mate Choice is Associated with Natural Fluctuations in Gonadal Steroid Levels Females are capable of expressing plasticity in their mate choices. Such plasticity can arise as a consequence of intrinsic factors that influence behavior. One such factor is gonadal hormones. We examined female […]

MADHOUN, N.M.; WILWERT, J.L.; COUGHLIN, D.J.; Widener Univ., Chester, PA: Parvalbumin Correlates with Relaxation Rate in the Swimming Muscle of Sheepshead and Kingfish Parvalbumin is a muscle protein that aids in relaxation from contraction. Parvalbumin binds myoplasmic Ca2+ during contractions, reducing calcium concentration and enhancing relaxation. Different isoforms of parvalbumin have varying affinities for calcium, […]

KNOTT, K.E.*; PUURTINEN, M.; VAN OOIK, T.; HYT�NEN, M.; KAITALA, V.; University of Jyv�skyl�, Finland: Parasite infection, heterozygosity and selfing in the hermaphroditic snail Lymnaea stagnalis We studied the relationship between heterozygosity and infection by trematode parasites in eight populations of Lymnaea stagnalis. Within natural populations, prevalences of trematode infection were high, from 37% to […]
