LIGNOT, J H; SECOR, S M; University Louis Pasteur / CNRS-Strasbourg ; University of Alabama: Postprandial morphological changes of the intestinal villi and enterocytes in the Burmese python As an apparent adaptive response to feeding infrequently on large meals, Burmese pythons (Python molurus) experience large regulatory swings in GI function and morphology with the start […]

GRAY, E M; BRADLEY, T J; Univ. of California, Irvine; Univ. of California, Irvine: Metabolic Rate in Female Mosquitoes: Age, Size, Activity and Feeding Effects Using flow-through respirometry, we have measured the pattern of CO2 release from adult female mosquitoes in the species Culex tarsalis. Individual rates of CO2 release and dry mass were also […]

SKOPEC, MM; KARASOV, WH; University of Wisconsin, Madison: Do salivary proline-rich proteins decrease the metabolic cost of tannin consumption? Tannins are polyphenolic compounds in plants that readily bind protein and can reduce palatability, digestibility and cause toxicity. Many mammals that come in contact with tannins in their diets have developed the ability to secrete proline-rich […]

WHEATLY, M. G.; GAO, Y; Wright State Univ., Dayton: The molecular biology of ion motive enzymes: lessons learned from comparative models Movement of ions across epithelial membranes involves an array of proteins broadly grouped into channels, pumps, antiporters and cotransporters. The molecular technologies have impacted the field of comparative ion transport. Over the past decade […]

BURIAN, R.M.; Virginia Tech: On the Difficult of Using Nucleotide Sequences Alone to Define Genes There has been considerable debate recently about the status of molecular concepts of the gene. Some authorities have argued for a concept, definition, or delimitation of genes as sequences of nucleotides without including the connection of the sequence to particular […]

MADERSON, PFA; HILLENIUS, WJ; Brooklyn College CUNY; College of Charleston: Exploding the myth of tubular feathers: a major evolutionary innovation requires only one novel mechanism The Prum/Brush model for feather origin and diversification (a) posits multiple developmental novelties appearing in an inherently untestable evolutionary sequence, (b) ignores aspects of form that reflect essential developmental and […]

Isotope ratios of common elements are often used in studies of energy flow […]

VANCE, Jason T.; ALTSHULER, Douglas L.; DICKINSON, Michael H.; ROBERTS, Stephen P.; Univ. of Nevada, Las Vegas; California Institute of Technology; California Institute of Technology; Univ. of Nevada, Las Vegas: High-speed kinematic analysis of honey bees (Apis mellifera) hovering in variable density atmospheres: Insights into aerodynamic reserve capacity and performance limitations For flying insects, behaviors […]

VOLTZOW, J.*; MARTIN, C.-L.; Univ. of Scranton, Pennsylvania, USA; Univ. of New England, National Marine Science Centre, New South Wales, Australia: Flow in Fissurellids: A Story Full of Holes Most fissurellid gastropods, or keyhole limpets, are characterized by a cap-shaped shell with an apical opening. Their mantle cavities contain paired organs, including a large pair […]

FISH, Frank/E; NICASTRO, Anthony/J; West Chester Univ., Pennsylvania; West Chester Univ. , Pennsylvania: Dynamics of the aerial maneuvers of spinner dolphins The spinner dolphin (Stenella longirostris(/i>) performs spectacular leaps from the water while rotating around its longitudinal axis up to seven times. Although twisting of the body while airborne has been proposed as the mechanism […]
