CHAPMAN, Robert*; JENNY, Matt; SCDNR/MRRI; Medical University of South Carolina/MBES: EcoGenomics: analysis of complex systems Ecogenomics is a convenient descriptor for the application of advanced molecular technologies to studies of organismal responses to environmental challenges in their natural settings. The development of molecular tools to survey changes in the transcript profile of thousands of genes […]

Meeting Abstract S8-1.7  Jan. 6  Sexual segregation in ungulates: proximate and ultimate causes RUCKSTUHL, KE; University of Calgary kruckstu@ucalgary.ca The even-toed ungulates are the most successful group of large herbivores, being native to almost every continent, and inhabiting all latitudes and altitudes. In most social ungulate species, males and females live in separate groups outside the breeding […]

Meeting Abstract S8-1.2  Jan. 6  Sex differences in locomotor performance and thermoregulation in reptiles: behavioral and ecological implications LAILVAUX, S; University of Antwerp slailvau@ua.ac.be Males and females from several animal taxa differ in locomotor performance abilities such as sprinting and jumping. These performance dimorphisms may be explained at least partially by sex differences in physiology. In ectotherms […]

Meeting Abstract S8-1.5  Jan. 6  Origin and evolution of novel phenotypes: From environmental induction to genetic inheritance in color displays BADYAEV, Alexander; University of Arizona abadyaev@email.arizona.edu The origin of novel phenotypes is one of the most controversial and unresolved questions in biology. Phenotypic accommodation of environmentally-induced developmental plasticity is thought to be an initial step in the […]

Meeting Abstract S8-1.1  Jan. 6  Functional and ecological correlates of ecologically-based dimorphisms in squamate reptiles VINCENT, S.E.*; HERREL, A; Stony Brook University svincent@ethol.zool.kyoto-u.ac.jp Sexual dimorphism in phenotypic traits associated with resource use is a widespread phenomenon throughout the animal kingdom. Ecological dimorphisms can be generated initially by sexual selection on body or head size, but are typically […]

Meeting Abstract S8-1.3  Jan. 6  Evolution of sexual dimorphism in habitat use and escape behaviour in Anolis lizards. VANHOOYDONCK, Bieke*; HERREL, Anthony; IRSCHICK, Duncan J; University of Antwerp, Wilrijk; University of Antwerp, Wilrijk; University of Massachusetts, Amherst bieke.vanhooydonck@ua.ac.be Evolutionary biologists have long been fascinated by intersexual differences. In most cases, quantification of sexual dimorphism has remained limited […]

Meeting Abstract S8-1.6  Jan. 6  Developmental evolution of BMPs: from postnatal epigenetic remodeling to adaptive genetic divergence YOUNG, Rebecca L*; BADYAEV, Alexander V; University of Arizona; University of Arizona rlyoung@email.arizona.edu Evolutionary studies of ecomorphological adaptations in vertebrates have revealed a common role for bone morphogenetic proteins (BMPs) in inducing developmental changes in skeletal morphology. Whereas the importance […]

Meeting Abstract S8-1.4  Jan. 6  Colour polymorphism without ecological niche divergence in the lacertid lizard Podarcis melisellensis HUYGHE, Katleen*; VANHOOYDONCK, Bieke; HERREL, Anthony; VAN DAMME, Raoul; Univ. of Antwerp, Belgium; Univ. of Antwerp, Belgium; Univ. of Antwerp, Belgium; Univ. of Antwerp, Belgium katleen.huyghe@ua.ac.be Different hypotheses have been proposed to explain the origin of phenotypic polymorphisms. Non-adaptive mechanisms […]

Meeting Abstract S8-1.1  Saturday, Jan. 5  The origin of Decapoda SCHRAM, F.R.; Burke Museum, University of Washington fschram@u.washington.edu Any effort to elucidate a decapod ancestor runs into several problems. First, while there is general agreement about relationships within Decapoda, there is considerable difference of opinion about the sister group of Decapoda. Some advocate Euphausiacea; others promote a […]

Meeting Abstract S8-1.5  Saturday, Jan. 5  Sperm Morphology and its Bearing on Decapod Phylogeny TUDGE, Chris; American University, Washington DC ctudge@american.edu The use of spermatozoal characters in helping to elucidate animal phylogeny (spermiocladistics – Jamieson, 1991) has recently been successfully applied in the decapod crustaceans. Most of the decapod taxa investigated for sperm morphology are published in […]
