CULP, C.E.*; FALKINHAM III, J.O.; BELDEN, L.K.; Virginia Polytechnic Institute and State University; Virginia Polytechnic Institute and State University; Virginia Polytechnic Institute and State University: Identification of the natural bacterial microflora on the skin of Eastern newts and bullfrog tadpoles Amphibian populations in several regions of the world appear to be declining due to infectious […]

GUADANGOLI, J.A.; BRAUN, A.M.; ROBERTS, S.P.; REIBER, C.L.; Touro University, Nevada; Dominican University; University of Nevada, Las Vegas; University of Nevada, Las Vegas: Hypoxia alters hemoglobin subunits in the adult Branchiopod Triops Longicaudatus Hemoglobin is a vital molecule in oxygen transport for many organisms. While ubiquitous among vertebrates, it occurs less frequently in invertebrate phyla. […]

LEE, S.G.; BADER, B.D.; CHANG, E.S.; MYKLES, D.L.; Colorado State Univ., Fort Collins, CO; Colorado State Univ., Fort Collins, CO; Bodega Marine Lab, Bodega Bay, CA; Colorado State Univ., Fort Collins, CO: High-throughput proteomic approaches for identifying molt-associated proteins in crustacean molting gland Regulation of the molting cycle in decapod crustaceans is mainly controlled by […]

THOMTON, J.D.*; TAMONE, S.L.; ATKINSON, S. ; AK SeaLife Center, U. of AK Fairbanks; U. of AK Southeast; AK SeaLife Center, U. of AK Fairbanks: Hemolymph Ecdysteroid Concentrations in Wild and Captive Alaskan Dungeness Crabs The currently accepted reproductive cycle of Alaskan female Dungeness crabs (Cancer magister) maintains that females molt and mate during summer […]

NADEAU, J.A.; CHATELAIN, K.B.; RUSSELL, D.J.; CONWELL, N.; OKAZAKI, R.K.; Siena College; Weber State University; Weber State University; Weber State University; Weber State University: Heat Shock Proteins in the Utah Crayfish, Pacifastacus gambelii The native Utah crayfish, Pacifastacus gambelii, can be exposed to high temperatures, especially in the summer season. These thermal stresses have often […]

YU, J.-K.*; HOLLAND, N.D.; HOLLAND, L.Z.; University of California, San Diego; University of California, San Diego; University of California, San Diego: FoxD protein evolution and the origin of vertebrate neural crest Neural crest is unique to vertebrates. Embryologically, neural crest derives from the edges of the neural plate and adjacent non-neural ectoderm, and undergoes an […]

SIMMONS, S.E.*; CROCKER, D.E.; COSTA, D.P.; Univ. of California, Santa Cruz; Sonoma State University, Rohnert Park; Univ. of California, Santa Cruz: Foraging strategies differ in sexually dimorphic northern elephant seals (Mirounga angustirostris). Separation of feeding from breeding is a distinctive life history trait of many phocids. Male and female elephant seals differ in their annual […]

MINSUK, S.B.; Konrad Lorenz Institute, Altenberg, Austria: First steps toward a generalized model cell for evo-devo computer simulations Developmental simulations usually model a few cell types in a simple tissue, and conform to details of specific organisms. Simulated evolution must model cells and tissues, but proceed at the level of organisms and populations in environments. […]

BLACKBURN, D.G.; JOHNSON, A.R.; PETZOLD, J.L. ; Trinity College, Hartford: Fetal membrane ultrastructure in the corn snake, Pantherina guttatus In amniotes, fetal (extraembryonic) membranes are responsible for all physiological exchange between eggs and their environments. The anatomical basis for such exchange is largely unknown in reptiles, and has not previously been studied in oviparous snakes. […]

TAYLOR, S.; BLAIR, K.; ARACENA, J.; Mississippi Univ. for Women; Mississippi Univ. for Women; Mississippi Univ. for Women: Feeding behavior of fruit flies (Drosophila melanogaster) on patches of sucrose solutions: Effects of food deprivation and quinine A field collected population of fruit flies (Drosophila melanogaster) was maintained in the laboratory to study foraging behavior on […]
