MOORE, C. W.*; YI, S-X.; LEE, JR., R. E.; Miami University; Miami University; Miami University: Does the rapid cold-hardening response protect Drosophila from cold-induced apoptosis? The rapid cold-hardening (RCH) response increases the cold tolerance of insects by protecting against non-freezing, cold-shock injury. Although the RCH response is well documented in a variety of arthropods, little […]

LOURDAIS, O.; DENARDO, D. F.*; HEULIN, B.; Arizona State University; Arizona State University; Station Biologique de Paimpont. UMR : Does gravidity influence thermoregulation in an oviparous reptile? Viviparity has evolved over 100 independent times in squamates, presumably because it provides an enhanced ability for females to regulate the thermal conditions of offspring development. Oviparous squamates […]

FORSMAN, A.M.*; SAKALUK, S.K.; VOGEL, L.A.; ARQUETTE, R.F.; THOMPSON, C.F.; Illinois State University, Normal; Illinois State University, Normal; Illinois State University, Normal; Illinois State University, Normal; Illinois State University, Normal: Do measures of female condition predict survival, condition, and immune response of nestling house wrens (Troglodytes aedon)? Advances in molecular techniques allow investigators to assess […]

LYNN , Sharon E.*; WINGFIELD, John C.; The College of Wooster; University of Washington: Dissociation of testosterone and male-male aggression in breeding Chestnut-collared longspurs, Calcarius ornatus Among males of many avian species, elevated testosterone (T) and aggressive behavior appear to be related: expression of aggression is accompanied by a rise in T secretion, and elevated […]

CASTA�EDA, L.E.*; NESPOLO, R.F.; ROFF, D.A.; Univ Austral de Chile; Univ Austral de Chile; Univ of California, Riverside: Dissecting the variance-covariance structure in insect physiology: the multivariate association between metabolism and morphology in the nymphs of the sand cricket (Gryllus firmus) How is the relationship between morphology and metabolism in arthropods? There exists a clear […]

FUENTES, S*; RICK, H; NOEL, J; University of Louisiana at Lafayette: Development of Real-Time PCR assays for rapid detection of Cylindrospermopsis raciborskii Blooms caused by toxic blue-green algae have repeatedly produced episodes of wild and domestic animal illness and death. The responsible cyanobacteria belong to about 40 genera including the most recently found toxin-producing cyanobacterium, […]

COX, Christian L.*; SECOR, Stephen M.; University of Alabama; University of Alabama: Determinants of energy efficiencies for juvenile Burmese pythons, Python molurus The relative proportion of ingested energy that is absorbed by the gut (digestive efficiency), becomes available for metabolism (assimilation efficiency), and is used for growth (production efficiency) varies with respect to meal type […]

MCCLOSKEY, K/L*; NESTLER, J/R; Walla Walla College; Walla Walla College: DIEL CYCLES OF ACTIVITY, METABOLISM, AND NUTRIENT EXCRETION IN THE TEMPERATE SEA CUCUMBER PARASTICHOPUS CALIFORNICUS Sea cucumbers (Holothuroidea) influence ocean communities by affecting physical and chemical characteristics of water and sediment through their deposit feeding and excretion activities. Diel cycles of in situ movement, metabolism, […]

SANTOS, N*; HOOPER, T; KIMBLE, M; St. Augustine College, Chicago; St. Augustine College, Chicago; Northeastern Illinois University: Cyanocytes in staged Limulus polyphemus trilobite larvae. Hemocyanins are the primary oxygen transporting proteins in arthropods. In some species, hemocyanin is produced in glandular tissues and secreted into the hemolymph, while in others, including Limulus polyphemus, specialized cells […]
