CHAPPELL, M.A.**; RUSSELL, G.A.; HAMMOND, K.A.; Univ. of California, Riverside; Univ. of California, Riverside; Univ. of California, Riverside: BMR is not repeatable over extended periods in deer mice Basal metabolic rate (BMR) is probably the most thoroughly investigated aspect of energy metabolism in vertebrate endotherms. Hundreds of studies have explored its mass allometry, phylogenetic and […]

SZAFRANSKA, Paulina A.*; ZUB, Karol; KONARZEWSKI, Marek; SPEAKMAN, John R.; Mammal Research Institute Polish Academy of Sciences; Mammal Research Institute Polish Academy of Sciences; University of Bialystok; University of Aberdeen: A positive association between resting and field metabolic rates in weasels A positive association between resting (RMR) and field metabolic rate (FMR) is one of […]

KROCHMAL, A.R.; University of Houston – Downtown: There�s no such thing as a free lunch: on the adaptive value of scavenging in snakes Snakes are generally considered consummate predators, and therefore, scavenging by snakes has traditionally been discounted or ignored. However, recent reviews, combined with the ubiquitous observation that captive snakes regularly feed on carrion, […]

BREELAND, T. B.**; STRAUSS, R. E.; Texas Tech University, Lubbock; Texas Tech University, Lubbock : School and Shoal Distributions in a Freshwater Catfish Species, Corydoras Paleatus (Callichthyidae) The South American armored catfish Corydoras paleatus has been observed to occur in nature in large schools, in smaller shoals, and individually or in pairs. These catfishes are […]

GRAYSON, D. L.*; HARRISON, J. F.; FEWELL, J. H.; Arizona State Univsersity; Arizona State Univsersity; Arizona State Univsersity: Foraging Effort and Metabolism in European and African Honey Bees African honey bees (Apis mellifera scutellata) are one of the most successful invasive species known, for they have spread from Southern Brazil throughout the Americas in less […]

SHEEHY III, C. M.*; LILLYWHITE, H. B.; Univ. of Florida, Gainesville; Univ. of Florida, Gainesville: Foraging Behaviors of Insular Cottonmouth Snakes Florida cottonmouth snakes (Agkistrodon piscivorus conanti) exhibit significant variation of foraging behavior on a single island at Cedar Keys, Florida. Snakes in this population characteristically remain beneath avian rookeries where colonial nesting birds drop […]

ENGESZER, RE*; ALBERICI DA BARBIANO, L; RYAN, MJ; PARICHY, DM; University of Washington, University of Texas at Austin; University of Texas at Austin; University of Washington ; University of Texas at Austin: An analysis of shoaling preference in the zebrafish, Danio rerio How social aggregations arise and persist is central to our understanding of evolution, […]

FERRER, R.P.*; ZIMMER, R.K.; Univ. of California, Los Angeles; Univ. of California, Los Angeles: When prey becomes predator: an ontogenetic shift in the role of olfaction. During development, sensory systems undergo changes in cell receptor machinery. Such modifications may alter the way an animal perceives its olfactory environment. Here we investigated a cannibalistic interaction between […]

GIBB, A. C.*; LIU, C.; SWANSON, B. O.; Northern Arizona University; Northern Arizona University; Pacific University: Pre-hatching escape behavior in the rainbow trout Teleost fishes employ diverse developmental strategies that have direct consequences on the ability to perform certain behaviors. Danio rerio, zebrafish, have indirect development, where embryos hatch within four days of spawning, and […]

GRANT, Jacqualine B.; Colorado State University: Ontogeny of defensive behavior and adaptive coloration in larvae of the panic moth, Saucrobotys futilalis Many lepidopteran species have radically different coloration in early and late larval instars. This ontogenetic variation in morphology is most likely due to temporal changes in the costs and benefits associated with foraging and […]
