GILLEN, C.M.*; HEILMAN, N.R.; WATSON, N.; SOMPLE, M.; GILLEN, K.M.; Kenyon College, Gambier, OH: Tissue distribution of the cation-chloride cotransporter, masBSC, in Manduca sexta . We examined the tissue distribution of the Manduca sexta cation-chloride cotransporter, masBSC. MasBSC has strong sequence similarity to vertebrate Na-K-Cl cotransporters. We expressed a 159 amino acid peptide from the […]

BOOTH, C.E.; HENRY, R.P.; Eastern Connecticut State Univ., Willimantic; Auburn University, Alabama: The role of branchial H ion excretion in acid-base regulation in euryhaline and stenohaline brachyuran crabs. Many aquatic animals are thought to use electroneutral ion exchanges (e.g., Na/H , Cl/ bicarbonate) across the gills or skin to regulate internal acid-base balance. Our understanding […]

HEAD, J.M.; TERWILLIGER, N.B.; Univ. of Oregon, Oregon Institute of Marine Biology; Univ. of Oregon, Oregon Institute of Marine Biology: The role of HIF-1a in crustacean responses to hypoxia. The habitats of most aquatic crustaceans are highly variable, particularly with respect to changing levels of oxygen. Fluctuations in factors such as salinity, temperature, and productivity […]

GIRI, T.; Texas A&M University: The occurrence of epibiota on the peppermint shrimp, Lysmata wurdemanni, and the effect of salinity changes on grooming behaviour Exposed substrata in marine environments are quickly colonized (fouled) by sessile organisms, such as protozoans, bryozoans and barnacles. Since hard substrate may be a limiting resource, epibiota will often attach to […]

SHAPIRO, M.D.; SCHLUTER, D.; KINGSLEY, D.M.; Howard Hughes Medical Institute and Stanford University School of Medicine; University of British Columbia; Howard Hughes Medical Institute and Stanford University School of Medicine: The genetic control of upper jaw morphology in threespine sticklebacks Extensive modifications in skeletal feeding structures underlie many of the morphological adaptations of vertebrates to […]

ECKHARDT, G. H. *; WATERMAN, J. M.; ROTH, J. D.; Univ. of Central Florida; Univ. of Central Florida; Univ. of Central Florida: The functional significance of play fighting in polar bears: are they asocial? Polar bears, Ursus maritimus, are widely considered asocial animals. Yet while waiting for the sea ice to form near Churchill, Manitoba, […]

BUDA, E/S*; SHAFER, T/H; University of North Carolina at Wilmington; University of North Calorina at Wilmington: The expression of two genes possibly involved in tanning and calcification of the cuticle in the blue crab, Callinectes sapidus. Decapod crustaceans, such as the blue crab, Callinectes sapidus, are covered and protected from their environment and potential predators […]

BEULIG, A.*; PILONIETA, M.C.; New College of Florida; New College of Florida: The effects of estrogenic pesticide on reproductive behavior of Cyprinodon variegatus, the sheepshead minnow . Endosulfan is an estrogenic insecticide commonly used in agriculture. Because it may become part of agricultural runoff it is important to assess its possible impact on the physiology […]

TANNER, C.A.*; RICART, T.M.; BORST, D.W.; LOVETT, D.L.; College of New Jersey, Ewing; Mt. Desert Island Biol. Lab., Salisbury Cove, ME; Illinois State University: The effect of osmotic conditions on methyl farnesoate levels in the green crab, Carcinus maenas We have shown previously that stress can increase methyl farnesoate (MF) levels in crustaceans. One type […]
