Meeting Abstract 19.5 Jan. 5 The effect of hydration state on activity in a free-ranging Sonoran Desert lizard, the Gila Monster, Heloderma suspectum. DAVIS, J.R.**; DENARDO, D.F.; Arizona State University, Tempe j.davis@asu.edu North American deserts can present significant challenges to animals because of variable, often extreme temperatures and limited energy and water resources. Challenges to fundamental physiological […]

The consequences of olfaction for predation in a natural stream habitat
Meeting Abstract 19.2 Jan. 5 The consequences of olfaction for predation in a natural stream habitat FERRER, R. P.*; ZIMMER, R. K.; University of California, Los Angeles rferrer@ucla.edu Despite significant advances in understanding the olfactory basis for predatory behavior in laboratory environments, little is known about the sense of smell in natural aquatic habitats. The California newt […]
Proceed with caution invalidating tests of the cost-benefit model of thermoregulation with spatially-explicit movement simulations
Meeting Abstract 19.4 Jan. 5 Proceed with caution: invalidating tests of the cost-benefit model of thermoregulation with spatially-explicit movement simulations SEARS, Michael W.; Southern Illinois University msears@zoology.siu.edu The Huey-Slatkin model of behavioral thermoregulation in lizards predicts that individuals should thermoregulate less effectively in costly environments. A recent test of this prediction (Blouin-Demers and Nadeau 2005) used published […]

Meeting Abstract 19.3 Jan. 5 A comparative study of sensory physiology and competitive interactions of the invasive round goby with three native species: slimy sculpin, spoonhead sculpin, and logperch BERGSTROM, MA*; MENSINGER, AF; Univ. of Minnesota Duluth; Univ. of Minnesota Duluth berg1102@d.umn.edu Population declines in native benthic fish populations across the Great Lakes have been attributed to […]
Why does genetic diversity of mitochondrial genes not reflect population size
Meeting Abstract 19.6 Thursday, Jan. 3 Why does genetic diversity of mitochondrial genes not reflect population size? KNOTT, K. E.; University of Jyvaskyla, Finland emily.knott@bytl.jyu.fi According to neutral theory, the amount of genetic variation within a population will be positively correlated with population size. However, according to a recent analysis by Bazin and colleagues (Science 312:570-572), mitochondrial […]
Population structure and gene flow in the scalloped hammerhead shark, Sphyrna lewini along the Eastern Pacific
Meeting Abstract 19.2 Thursday, Jan. 3 Population structure and gene flow in the scalloped hammerhead shark, Sphyrna lewini along the Eastern Pacific NANCE, H.A.*; MARKO, P.B.; KLIMLEY, A.P.; Clemson Univ.; Clemson Univ.; Univ. of California, Davis hnance@clemson.edu Large, cosmopolitan marine fishes appear to have great potential for panmixia throughout their geographic ranges via long-distance migration. One common […]
Population genetics of the HoxA2 enhancer in killifish (Teleostei Fundulus)
Meeting Abstract 19.5 Thursday, Jan. 3 Population genetics of the HoxA2 enhancer in killifish (Teleostei: Fundulus) RAINCROW, J.D.*; CHIU, C.H.; Rutgers University; Rutgers University raincrow@biology.rutgers.edu Hox genes encode transcription factors that play an important role in body axis formation and are likely to have a major influence on the development and evolution of body plans. Hox genes […]
Morphological and genetic variation in allopatric populations of Acanthina angelica in the northern Gulf of California
Meeting Abstract 19.1 Thursday, Jan. 3 Morphological and genetic variation in allopatric populations of Acanthina angelica in the northern Gulf of California COTA, R.M.*; SHUSTER, S.M.; Northern Arizona University, Flagstaff; Northern Arizona University, Flagstaff raena.cota@nau.edu Acanthina angelica is a dioecious marine gastropod, endemic to the northern Gulf of California. Four allopatric populations near Puerto Peñasco, Sonora, MX, […]

Meeting Abstract 19.3 Thursday, Jan. 3 Genetic diversity and gene flow of the sand skink, Plestiodon reynoldsi, among continuous and interrupted scrub habitat in central Florida FOX, A.M.*; SCHREY, A.; MUSHINSKY, H.; MCCOY, E.; University of South Florida; University of South Florida; University of South Florida; University of South Florida amfox@mail.usf.edu The sand skink, Plestiodon reynoldsi, is […]
Genetic connectivity in Sterechinus (Echinodermata Echinoidea) from South American and Antarctic waters
Meeting Abstract 19.4 Thursday, Jan. 3 Genetic connectivity in Sterechinus (Echinodermata: Echinoidea) from South American and Antarctic waters COX, L.N.*; HALANYCH, K.M.; Clemson University; Auburn University lncox@clemson.edu The genus Sterechinus Koehler, 1901 represents the only regular urchins found in Antarctic waters. In particular, S. neumayeri, S. antarcticus, and S. agassizi are morphologically similar species found in the […]
