Gene expression during development and diapause in a vertebrate extremophile
Meeting Abstract 49-4 Tuesday, Jan. 5 10:45 Gene expression during development and diapause in a vertebrate extremophile ROMNEY, A. L. *; PODRABSKY, J. E.; Portland State University; Portland State University arom2@pdx.edu http://www.pdx.edu/podrabsky-lab/ The annual killifish, Austrofundulus limnaeus, survives in harsh and unpredictable environments through their ability to enter into embryonic diapause. Diapause is a pre-programmed exit from […]
Variation in sperm morphology between native and introduced populations of three Anolis lizard species
Meeting Abstract 48-4 Tuesday, Jan. 5 11:00 Variation in sperm morphology between native and introduced populations of three Anolis lizard species KAHRL, A.F.*; COX, R.M.; University of Virginia; University of Virginia afk7df@virginia.edu Sperm morphology is highly variable among species, but less is known about its variation among individuals and populations. Anolis lizards are native throughout the Caribbean […]

Tissue-specific variation in mitochondrial function and implications for the costs of reproduction
Meeting Abstract 48-2 Tuesday, Jan. 5 10:30 Tissue-specific variation in mitochondrial function and implications for the costs of reproduction HOOD, WR*; MOWRY, AV; KAVAZIS, AN; Auburn University; Auburn University ; Auburn University wrhood@auburn.edu http://thehoodlaboratory.com A central tenet of biology is that the costs of reproduction contribute to reduced future fecundity and earlier senescence, but the mechanisms that […]
Sexual selection on skeletal shape in Carnivora
Meeting Abstract 48-3 Tuesday, Jan. 5 10:45 Sexual selection on skeletal shape in Carnivora MORRIS, J.S.*; CARRIER, D.R.; University of Utah; University of Utah j.s.morris@utah.edu Because lifetime reproductive success is often dependent upon the ability to compete for mates, males tend to be more specialized for physical competition than females. Among mammals, polygyny enforced by male-male competition […]
Parasitism and ornamentation a within-individual study in the common yellowthroat
Meeting Abstract 48-6 Tuesday, Jan. 5 11:30 Parasitism and ornamentation: a within-individual study in the common yellowthroat HENSCHEN, A.E.*; WHITTINGHAM, L.A.; DUNN, P.O.; Univ. of Wisconsin, Milwaukee; Univ. of Wisconsin, Milwaukee; Univ. of Wisconsin, Milwaukee hensche9@uwm.edu Elaborate ornaments are hypothesized to honestly signal individual quality, including the ability of an individual to combat parasitic infection. Although there […]
Can we detect a physiological signature of cost of reproduction
Meeting Abstract 48-1 Tuesday, Jan. 5 10:15 Can we detect a physiological signature of cost of reproduction? WILLIAMS, TD*; FOWLER, MA; Simon Fraser Univ., Burnaby; Springfield College, MA tdwillia@sfu.ca http://www.sfu.ca/biology/faculty/williams/ Increased investment in current reproduction can have a negative influence on survival to, or future fecundity of, a subsequent breeding attempt. Life-history theory predicts that current and […]
Trail following by planktonic microcrustacean copepods
Meeting Abstract 47-2 Tuesday, Jan. 5 10:30 Trail following by planktonic microcrustacean copepods YEN, J*; PENDER-HEALY, L; HEAPHY, M; Georgia Institute of Technology; Georgia Institute of Technology; Gwinette K12 jeannette.yen@biology.gatech.edu The response of precise three-dimensional trail following by the aquatic microcrustacean copepod is a consequence of viscosity-induced attenuation of mixing that enables the persistence of small-scale chemical […]
