Meeting Abstract 106.3  Saturday, Jan. 7  Why snakes flick their tongues: a fluid dynamics approach RYERSON, WG*; SCHWENK, K; University of Connecticut william.ryerson@uconn.edu The forked tongue of snakes is used to collect chemical molecules (odorants) from the environment and deliver them to the vomeronasal organs in the roof of the mouth. Snakes use two methods to sample […]

Meeting Abstract 106.1  Saturday, Jan. 7  Numerical Simulations of Odorant Detection by Crustacean Olfactory Hair Arrays SCHUECH, Rudi*; STACEY, Mark; KOEHL, Mimi; Univ. of California, Berkeley rudis@berkeley.edu Many marine crustaceans flick sensory antennules through the water to actively sample turbulent odor plumes. An important step in odorant detection is the transport of odorant molecules from the filamentous […]

Meeting Abstract 106.5  Saturday, Jan. 7  Nectar drinking KIM, Wonjung; GILET, Tristan*; BUSH, John W.M.; Massachusetts Institute of Technology, Cambridge; University of Liege, Belgium; Massachusetts Institute of Technology, Cambridge Tristan.Gilet@ulg.ac.be Nectar drinkers must feed efficiently due to the threat of predation. The sweetest nectar offers the greatest energetic rewards, but the sharp increase of viscosity with sugar […]

Meeting Abstract 106.4  Saturday, Jan. 7  How nectar-feeding bats lap: nectar uptake and ingestion in Glossophaga soricina HARPER, C.J.*; SWARTZ, S.M.; BRAINERD, E.L.; Brown University, Providence; Brown University, Providence; Brown University, Providence caroline_harper@brown.edu In nectar-feeding bats, the tongue tip resembles a brush because it is covered with long filamentous papillae. In Glossophaga soricina, these hairlike papillae are […]

Meeting Abstract 106.2  Saturday, Jan. 7  Fluid dynamics of antennule flicking of the terrestrial hermit crab, Coenobita rugosus (Decapoda: Anomura) WALDROP, LD; Univ. of California, Berkeley lwaldrop@berkeley.edu Many marine decapod crustaceans sense chemical signals (odors) in their surroundings to find food and mates using first antennae (antennules) which bear arrays of chemosensory hairs (aesthetascs). The fluid dynamics […]

Meeting Abstract 105.4  Saturday, Jan. 7  Ontogenetic and sex specific variation in chemical sequestration by a toxic herbivore FORDYCE, J.A.*; NICE, C.C.; DIMARCO, R.D.; University of Tennessee; Texas State University; University of Tennessee jfordyce@utk.edu Many insect herbivores sequester plant secondary compounds that in turn provide them with defense against natural enemies. The pipevine swallowtail, Battus philenor L., […]

Meeting Abstract 105.2  Saturday, Jan. 7  Impacts of elevated seawater temperature on Antarctic amphipod feeding choices for chemically-deterrent macroalgae SCHRAM, J.B.*; MCCLINTOCK, J.B.; AMSLER, C.D.; BAKER, B.J.; Univ. of Alabama at Birmingham; Univ. of Alabama at Birmingham; Univ. of Alabama at Birmingham; Univ. of South Florida jbschram@uab.edu As global temperatures continue to increase as part of the […]

Meeting Abstract 105.1  Saturday, Jan. 7  Cold-exposure compromises feeding resistance toward seaweed secondary metabolites in the sea urchin Arbacia punctulata. CRAFT, Jonathan D*; DELORENZO, ME; SOTKA, EE; College of Charleston craftjd@gmail.com Ambient temperature and plant secondary metabolites are common stressors for herbivores, but there are more examples of their independent, rather than combined, effects. We assessed whether […]

Meeting Abstract 105.3  Saturday, Jan. 7  Chemical defense of the eastern newt (Notophthalmus viridescens): variation in efficiency against different consumers and in different habitats MARION, Z.H.*; HAY, M.E.; University of Tennessee, Knoxville; Georgia Institute of Technology zmarion@utk.edu Amphibian secondary metabolites are well known chemically, but their ecological functions are poorly understood⎯even for well-studied species. For example, the […]

Meeting Abstract 104.3  Saturday, Jan. 7  Turbulent mixing diminishes discrimination of food and predator risk odor sources by altering small scale structure of signals impinging on blue crab antennules. WEISSBURG, M.J.; Georgia Tech marc.weissburg@biology.gatech.edu Animals frequently are challenged with the task of responding appropriately to chemical signals when they are intermingled or mixed with odors from multiple […]
