Meeting Abstract 100.2  Wednesday, Jan. 7  Paracellular and total glucose absorption increase with age in nestling House sparrows BRZEK, P.*; CAVIEDES-VIDAL, E.; KARASOV, W.H.; University of Wisconsin, Madison; Universidad Nacional de San Luis-CONICET, Argentina; University of Wisconsin, Madison pbrzek2@wisc.edu Diet digestive efficiency has been found to increase with age in nestling birds. Age-specific changes in activity of […]

Meeting Abstract 100.9  Wednesday, Jan. 7  Impact of meal fat content on the postprandial responses of the Burmese python SECOR, Stephen M.*; LIGNOT, Jean-Herve; University of Alabama; CNRS, DEPE, Strasbourg ssecor@biology.as.ua.edu Prey vary significantly in body fat as a function of season and the availability and composition of their diet. Largely unknown is the impact that meal […]

Meeting Abstract 100.4  Wednesday, Jan. 7  Does diet quality alter the temperature-size rule? DIAMOND, S.E.*; KINGSOLVER, J.G.; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill sdiamond@email.unc.edu How does variation in diet quality and temperature interact to affect survival, size and development time in herbivores? We conducted laboratory experiments with the tobacco hornworm, Manduca […]

Meeting Abstract 100.3  Wednesday, Jan. 7  Activity of intestinal carbohydrases responds to multiple dietary signals in nestling House sparrows BRZEK, P.; KOHL, K.; CAVIEDES-VIDAL, E.; KARASOV, W.H.*; University of Wisconsin, Madison; University of Wisconsin, Madison; Universidad Nacional de San Luis-CONICET, Argentina; University of Wisconsin, Madison pbrzek2@wisc.edu A simple adaptive modulation hypothesis predicts that digestive enzyme levels are […]

Meeting Abstract 100.5  Thursday, Jan. 7  Mapping the Epigenetic Landscape: Rediscovering Waddington in the Post-Genomic Age JAMNICZKY, H.A.*; BOUGHNER, J.C.; GONZALEZ, P.N.; PARSONS, T.E.; POWELL, C.D.; ROLIAN, C.; SCHMIDT, E.J.; BOOKSTEIN, F.L.; HALLGRIMSSON, B.; Univ. of Calgary, Canada; Univ. of Calgary, Canada; Univ.

Meeting Abstract 100.4  Thursday, Jan. 7  Integration of squirrel mandibles ZELDITCH, M.L.*; SWIDERSKI, D.L.; Univ of Michigan, Ann Arbor; Univ of Michigan, Ann Arbor zelditch@umich.edu Understanding how developmental modules are assembled into functionally integrated morphologies is central to our understanding of biological organization. Morphological integration, a key part of that organization, coordinates variation among parts, maintaining relationships […]

Meeting Abstract 100.3  Thursday, Jan. 7  Evolutionary reorganization of moth wing patterns towards a ‘dead leaf’ resemblance SUZUKI, Takao*; KURATANI, Shigeru; RIKEN CDB, Japan; RIKEN CDB, Japan tsuzuki@cdb.riken.jp How an enormous organismal diversity and complexity could have evolved is a fundamental question of design principles of living organisms. As seen in vertebrate head skeleton evolution, the diversity […]

Meeting Abstract 100.2  Thursday, Jan. 7  Evolutionary lability of integration in Cambrian ptychoparioid trilobites WEBSTER, M.*; ZELDITCH, M.L.; Univ. Chicago; Univ. Michigan mwebster@geosci.uchicago.edu Phenotypic integration can constrain evolution by channeling variation into few dimensions: lineages characterized by strong and invariant integration structures should have little capacity to generate morphological novelty, especially if integration arises through direct interactions […]

Meeting Abstract 100.1  Thursday, Jan. 7  Darwin’s Avicularia: How an Early Sense of Modularity Links Vestigiality, Functional Innovation and the Evolution of Polymorphism CARTER, M.C.; LIDGARD, S.*; GORDON, D.P.; GARDNER, J.P.A.; Victoria University of Wellington, New Zealand; Field Museum, Chicago ; National Institute of Water and Atmospheric Research, Wellington, New Zealand ; Victoria University of Wellington, New […]
