Recent song experience alters the threshold for female mate choice

Meeting Abstract 86.5  Sunday, Jan. 6  Recent song experience alters the threshold for female mate choice LYONS, S.M.*; BEAULIEU, M.; SOCKMAN, K.W.; University of North Carolina, Chapel Hill lyonssm@live.unc.edu The costs of mate choice can be high, and therefore females should adjust their threshold for choice according to the prevalence of high-quality males. In many songbird species, […]

Constraints on song complexity generalize across multiple songbirds

Meeting Abstract 86.4  Sunday, Jan. 6  Constraints on song complexity generalize across multiple songbirds TAFT, BN; Univ. of Wisconsin, Parkside truthauction@gmail.com Complex signals may evolve in response to different selection intensities, either continuously increasing in elaboration or reaching a steady state that is maintained by constraints. Detailed quantitative measures of signal complexity can help identify these different […]

Call timing preferences in gray treefrogs, Hyla versicolor

Meeting Abstract 86.1  Sunday, Jan. 6  Call timing preferences in gray treefrogs, Hyla versicolor HUMFELD, S. C.*; SCHWARTZ, J.; MARSHALL, V. T. ; University of Missouri; Pace University; University of Scranton humfelds@missouri.edu In a variety of animal taxa, females often show preferences based on the relative timing of sexual advertisement signals produced by different males. Such preferences […]

Thermal Acclimation in Rainbow Smelt, Osmerus mordax, Leads to Faster Myotomal Muscle Contractile Properties and improved swimming performance

Meeting Abstract 85.1  Sunday, Jan. 6  Thermal Acclimation in Rainbow Smelt, Osmerus mordax, Leads to Faster Myotomal Muscle Contractile Properties and improved swimming performance. COUGHLIN, DJ*; WOYTANOWSKI, JR; Widener Univ.; Widener Univ. djcoughlin@widener.edu Rainbow smelt (Osmerus mordax) display an impressive ability to acclimate to very cold water temperatures. These fish express both anti-freeze proteins and glycerol in […]

Temperature dependent variation in respiratory patterns and spiracular control in Rhodnius prolixus

Meeting Abstract 85.2  Sunday, Jan. 6  Temperature dependent variation in respiratory patterns and spiracular control in Rhodnius prolixus HEINRICH, EC*; BRADLEY, TJ; Univ. of California, Irvine; Univ. of California, Irvine eheinric@uci.edu Our current understanding of insect respiratory control indicates that spiracular activity is regulated by two interacting feedback loops which monitor and respond to changes in internal […]

Limited thermal acclimation capacity in a salamander, Desmognathus brimleyorum

Meeting Abstract 85.4  Sunday, Jan. 6  Limited thermal acclimation capacity in a salamander, Desmognathus brimleyorum YOUNG, V.KH.**; GIFFORD, M.E.; Clemson Univ.; Univ. Arkansas, Little Rock vkhilli@clemson.edu Temperature is a critical factor impacting the fitness of ectotherms. Previous studies have indicated that many ectotherms have the ability to adjust their physiological capabilities to cope with variation in their […]

Developmental physiology Predicting Winners and Losers to environmental change

Meeting Abstract 85.3  Sunday, Jan. 6  Developmental physiology: Predicting “Winners and Losers” to environmental change MANAHAN, D.T.*; HEDGECOCK, D.; Univ. Southern California; Univ. Southern California manahan@usc.edu Physiological variance is clearly evident in the biological responses of conspecifics to changing environmental conditions. This variance cannot fully be attributed to experimental error – some of the variance likely represents […]

Turning up the Heat Investigating the Physiological Effects of Climate Change on Mammalian Herbivores

Meeting Abstract 84.1  Sunday, Jan. 6  Turning up the Heat: Investigating the Physiological Effects of Climate Change on Mammalian Herbivores KURNATH, P.*; DEARING, M.D.; Univ. of Utah, Salt Lake City; Univ. of Utah, Salt Lake City patrice.kurnath@utah.edu Climate change is causing range shifts and population declines in many animal populations, particularly mammalian herbivores. One hypothesis to explain […]

Temperatures of Trekking Turtles Estimates by Water-filled Models and Hollow Te Thermometers

Meeting Abstract 84.5  Sunday, Jan. 6  Temperatures of Trekking Turtles: Estimates by Water-filled Models and Hollow Te Thermometers KROCHMAL, A.R.*; BAKKEN, G.S.; Washington College; Indiana State University akrochmal2@washcoll.edu Aquatic turtles take to land during oviposition or when seeking out new aquatic habitats. Though such overland treks are central to the biology of aquatic turtles, the physiological strain […]

Microclimatic research priorities for predicting the effects of climate change

Meeting Abstract 84.6  Sunday, Jan. 6  Microclimatic research priorities for predicting the effects of climate change POTTER, K. A.*; PINCEBOURDE, S.; WOODS, H. A.; University of Montana; Université François Rabelais; University of Montana kristen.potter@mso.umt.edu Considerable effort now focuses on predicting how species will respond to climate change. Nonetheless, statistical models that predict species’ distributions remain difficult to […]
