Meeting Abstract 125.5  Monday, Jan. 7  Metabolic signals differentially regulate trade-offs between the reproductive and immune systems in female Siberian hamsters CARLTON, E.D.*; COOPER, C.L.; DEMAS, G.E.; Indiana Univ., Bloomington; Claflin Univ., Orangeburg, SC; Indiana Univ., Bloomington elcarlto@indiana.edu Most free-living animals have finite energy stores that they must allocate to different physiological processes. As such, when energy […]

Meeting Abstract 125.3  Monday, Jan. 7  Impact of food restriction on immune function in altricial house sparrow nestlings KILLPACK, T.L.*; CARREL, E; KARASOV, W.H.; Univ. of Wisconsin, Madison; MMSD High School Science Internship Program; Univ. of Wisconsin, Madison tkillpack@wisc.edu If resources are limiting, then trade-offs may occur between immune defense and life history components such as growth […]

Meeting Abstract 125.2  Monday, Jan. 7  Immune defenses of captive and wild spotted hyenas (Crocuta crocuta): a comparative analysis FLIES, AS*; HOLEKAMP, KE; GRANT, CK; MANSFIELD, LS; Michigan State University; Michigan State University; Custom Monoclonals International; Michigan State University fliesand@msu.edu Evolutionary processes have shaped the vertebrate immune system over time, but proximate mechanisms control activation, duration, and […]

Meeting Abstract 124.4  Monday, Jan. 7  The biochemical basis for honest signaling via carotenoid pigments HILL, G. E.*; JOHNSON, J. D.; Auburn Univ.; Auburn Univ. ghill@auburn.edu Tradeoffs in allocation of carotenoid pigments between use in immune defense versus use in ornamentation have been widely stated as the means by which the honesty of ornamental coloration is maintained. […]

Meeting Abstract 124.3  Monday, Jan. 7  Ontogenetic color variation in the sea star Pisaster ochraceus as an adaptation to avoid predation by gulls KRAUSZER, M.; LEIKEN, A.; ELLIOTT, J.K.*; Univ. of Puget Sound, Tacoma jkelliott@ups.edu Early life history stages of many species are often camouflaged to reduce detection by visual predators because they are more vulnerable than […]

Meeting Abstract 124.1  Monday, Jan. 7  Dietary carotenoids increase non-carotenoid coloration of female convict cichlids (Amantitlania nigrofasciata). BROWN, AC*; MCGRAW, KJ; CLOTFELTER, ED; Univ. of Massachusetts Amherst; Amherst College; Arizona State Univ. acbro0@cns.umass.edu The carotenoid tradeoff hypothesis states that carotenoids must be traded-off among competing demands, but this is rarely tested in ornamented females. We used the […]

Meeting Abstract 124.2  Monday, Jan. 7  Covariation of dorsal pattern, locomotor performance and escape behavior MILES, D.B*; Ohio University urosaurus@gmail.com As temperatures rise and habitats become less favorable, species may shift their distributions, adapt to the new environments, or go extinct. However, phenotypic plasticity is likely to be an immediate response for coping with climate change. We […]

Meeting Abstract 123.6  Monday, Jan. 7  Thermal Physiology of albacore tuna, , as revealed through archival tagging data SNYDER, S*; KOHIN, S; CHILDERS, J; FRANKS, P.J.S.; Scripps Institution of Oceanography, UCSD; Southwest Fisheries Science Center; Southwest Fisheries Science Center; Scripps Institution of Oceanography, UCSD smsnyder@ucsd.edu Juvenile albacore, Thunnus alalunga, were tagged with archival tags in two regions […]

Meeting Abstract 123.5  Monday, Jan. 7  The genetics of cold tolerance in fruit flies dissected using bulk segregant analysis of artificial selection lines NOH, S*; HAHN, DA; MORGAN, TJ; Kansas State University suegene.noh@gmail.com A species’ ability to adapt to cold temperatures can determine species distributions and influence seasonality. Drosophila melanogaster falls into a reversible coma when exposed […]

Meeting Abstract 123.2  Monday, Jan. 7  Selection for cold tolerance alters the maintenance of metabolic homeostasis during cold exposure in Drosophila melanogaster.
