WILKENS, L/A; HOFMANN, M/H; Univ. of Missouri-St. Louis; Univ. of Bonn, Germany: Electrosensory neuroanatomy in the paddlefish CNS The paddlefish uses its electrosense for detecting planktonic food, a novel adaptation of passive electroreception based on an extensive array of ampullary receptors on its head and elongated rostrum. Juvenile fish rely on the accurate location of […]

CORNELIUS, J.M.; BREUNER, C.W.; HAHN, T.P.; Univ. of California, Davis; Univ. of Texas, Austin; Univ. of California, Davis: Effects of food reduction on stress reactivity in an irruptive nomad, the red crossbill Many animals time their migratory movements seasonally in order to exploit an abundant but temporary food source. Some opportunists specialize on food sources […]

HARMS, H.K.*; BOWDEN, R.M.; Illinois State University; Illinois State University: Effects of corticosterone exposure during development on hatchling red-eared slider turtles, Trachemys scripta In oviparous organisms maternal physiology has the potential to influence offspring, one route of influence being the transfer of steroids to yolk. Due to the lipophilic nature of steroids, they may become […]

BIARDI, James E; Univ. of California, Davis and San Francisco State University: Ecological and Evolutionary Context of Mammalian Resistance to Snake Venoms Snake venoms are a complex mixture of proteins, polypeptides, biogenic amines, and other components that may have neurotoxic, hemostatic, and/or hemorrhagic effects on prey. Their primary functions are to immobilize prey and initiate […]

PIERCE, A.L.; SHIMIZU, M.; DICKHOFF, W.W.; Univ Washington, Seatte; Univ Washington, Seattle; NOAA-Fisheries: EFFECTS OF METABOLIC HORMONES ON INSULIN-LIKE GROWTH FACTOR BINDING PROTEIN-1 (IGFBP-1) MESSENGER RNA LEVEL IN PRIMARY CULTURED SALMON HEPATOCYTES Insulin-like growth factor (IGF) binding proteins (IGFBPs) modulate the effects of the IGFs, major stimulators of vertebrate growth and development. Work in mammals […]

RICCI, C.; CAPRIOLI, M.; State Univ. , Milan; State Univ., Milan: Dormancy of Bdelloid Rotifers: costs and limits Dormancy of bdelloid rotifers is commonly cued by water evaporation and is defined as anhydrobiosis. Costs and limits of anhydrobiosis were investigated and post-recovery life histories were recorded in bdelloid rotifers. Dormancy produced a sort of time […]
