BOLKER, J.A.*; GANNETT, C.; University of New Hampshire; Loyola College in Maryland: Using fictional species to teach real science Science students spend much time and energy learning facts. But scientists know that facts are only the beginning: the deeper understanding that comes from integrating data with general principles, and from generating new questions, is the […]

AZIZI, E.*; LANDBERG, T.; WASSERSUG , R.J.; Brown Univ., Providence, RI; Univ. of Connecticut, Storrs, CT; Dalhousie Univ., Halifax, Canada and Univ. of Hamburg, Germany: Trunk mechanics during tadpole locomotion Anuran larvae show large lateral oscillations at both the tip of the tail and the snout while swimming in a straight line. Although the lateral […]

KREFT, J. M.**; MCCANDLISH, D. M.; REYNOLDS, L. W.; MERZ, R. A.; Swarthmore College; Swarthmore College; Swarthmore College; Swarthmore College: Trees pumping iron: Seasonal changes in material properties of branch wood in Sugar Maple (Acer saccharum) and Bur Oak(Quercus macrocarpa) Though structural engineers have developed a large dataset on the material properties of wood, these […]

SCHAD, KM*; FAUTH, JE; Univ. of Central Florida, Orlando; Univ. of Central Florida, Orlando: Tree call of treefrogs: more than just rain calls During the breeding season, males of several treefrog species give diurnal vocalizations that are commonly called rain calls or tree calls. The mating benefit of calling from the tops of trees is […]

REIDA, M.K.*; JANZEN, F.J.; Iowa State University; Iowa State University: The role of incubation temperature in inducing external abnormalities observed in neonatal painted turtles (Chrysemys picta) derived from natural nests Phenotypic abnormalities occur in offspring at low frequencies in most wild populations. In turtles, laboratory experiments have identified extreme temperatures experienced during embryonic development as […]

MARTIN, Gary G.; Occidental College, Los Angeles: The peritrophic membrane of the ridgeback prawn, Sicyonia ingentis Peritrophic membranes (PTM) are acellular layers that separate ingested food from the gut epithelium and persist as wrappers of fecal pellets. Although found in several protostomes, they are most thoroughly studied in insects, and to a lesser extent other […]

PEREZ-REYES, O.*; HERNANDEZ-GARCIA, P.; ROSA-MOLINAR, E.; Univ. of Puerto Rico-Rio Piedras; Univ. of Puerto Rico-Rio Piedras; Univ. of Puerto Rico-Rio Piedras: The motor neurons innervating the pereiopods of “Atya lanipes”” and “A. scabra“ Members of the genus, “Atya” (family Atyidae) have a passive filtration system that involves complex adaptations (anatomical and ecological specializations) in their […]

CHENG, Chia Wei*; HORNG, Shwu Bin; National Taiwan University: The mechanism and adaptation of Egg-dumping behavior of Callosobruchus maculatus Egg-dumping is a behavior that a female lays eggs on unsuitable places under conditions of host deprivation. All these eggs will die at the very beginning of life. Furthermore, because the female does not feed as […]

JURY, Steven H.*; BETKA, Marlies; LINELY, Tim; HARRIS, H.W.; MariCal, Inc.: The interaction of low pH, aluminum, and calcium on olfaction of Atlantic salmon (Salmo salar) The interaction of pH, aluminum (Al) and calcium (Ca) on olfactory nerve activity and Na/K ATPase in olfactory lamellae was determined for Atlantic salmon (Salmo salar). Parr were reared […]

SHETLAR, R; University of Central Florida: The effect of active learning strategies in undergraduate biology education There has been much written about different ways to engage undergraduate biology students in the learning process, i.e., to make them active learners. While active learning has generally been the norm in laboratories, it has been perhaps less so […]
