Meeting Abstract 37.2  Jan. 5  Metamorphic remodeling and the evolution of larval morphology in the carnivorous tadpole Lepidobatrachus laevis INFANTE, C.R.; Harvard University los@oeb.harvard.edu Members of the frog subfamily Ceratophryinae (Anura: Leptodatylidae) are known for the enlarged heads, massive jaws, and aggressive predatory natures of their adult forms. As tadpoles, however, each of the three genera that […]

Meeting Abstract 37.6  Jan. 5  Life history strategy affects escape performance of endangered Colorado River fish species GIBB, A. C.*; FERRY-GRAHAM, L. A.; Northern Arizona University; Moss Landing Marine Laboratories Alice.Gibb@nau.edu Many native fishes of the Colorado River are Cypriniformes (Teleostei). Because cypriniform fish have no parental care and produce eggs with small yolks, their larvae are […]

Meeting Abstract 37.1  Jan. 5  Diverse responses with identical genes: Identification of a core set of thyroid hormone-induced genes across tissues during frog metamorphosis BUCHHOLZ, D.R.; Dep’t of Biological Sciences, University of Cincinnati buchhodr@ucmail.uc.edu Thyroid hormone plays a central role in vertebrate post-embryonic development. Amphibian metamorphosis provides a unique opportunity to examine thyroid hormone-dependent developmental changes, which […]

Meeting Abstract 36.1  Jan. 5  Ubiquity of many-to-one mapping in functional traits: examples and evolutionary implications ALFARO, ME*; COLLAR, DC; WAINWRIGHT, PC; Washington State University; University of California, Davis; University of California, Davis alfaro@wsu.edu Many functional traits can be decomposed into the emergent functional property and its underlying parts. For example, maximum bite force is determined by […]

Meeting Abstract 36.3  Jan. 5  Structure and function of hind limb feathers in Archaeopteryx lithographica LONGRICH, Nicholas; University of Calgary longrich@ucalgary.ca A restudy of the Berlin Archaeopteryx was undertaken to understand the morphology and function of the hind limb feathers. Feathers cover the legs of the Berlin specimen, extending from the cranial margin of the tibia and […]

Meeting Abstract 36.5  Jan. 5  Non-algae scraping vs algae scraping, comparison between Synodontis and Atopochilus (Siluriformes: Mochokidae) IDE, C.*; DE PUYSSELEIR, J.; HUYSENTRUYT, F.; GEERINCKX, T.; ADRIAENS, D.; Ghent University celine.ide@ugent.be Until recently specializations related to algae-scraping have been studied in cichlids and loricariid catfishes, but very little has been done on the algae-scraping species of the […]

Meeting Abstract 36.2  Jan. 5  Evolving to be short and stubby � orthogenesis and grades of evolution in body plan in lizards. BERGMANN, PJ*; MEYERS, JJ; IRSCKICK, DJ; University of Massachusetts at Amherst; University of Massachusetts at Amherst; University of Massachusetts at Amherst pjbergma@nsm.umass.edu Evolutionary changes in body proportions are of central interest in evolutionary biology, as […]

Meeting Abstract 36.4  Jan. 5  Discordance between mechanical and morphological diversity in the suction feeding mechanism of centrarchid fishes COLLAR, DAVID C; University of California, Davis dccollar@ucdavis.edu Morphological diversity is widely used to infer ecological variation among species because differences in form underlie variation in functional performance of ecological tasks. However, complexity in the relationship between form […]

Meeting Abstract 36.6  Jan. 5  Covariation between morphological and behavioral evolution in lizards MCBRAYER, LD*; CORBIN, CE; STAYTON, CT; Georgia Southern Univ.; Bloomsburg Univ.; Bucknell Univ. lancemcbrayer@georgiasouthern.edu Lizards (non-ophidian squamates) are an ecologically diverse, species rich clade of terrestrial vertebrates. Morphologically, lizards are also very diverse; they range over an order of magnitude in body size and […]

Meeting Abstract 35.4  Jan. 5  Trophic enrichment without change in diet: An ontogenetic shift in &delta15N during insect metamorphosis TIBBETS, T. M.*; WHEELESS, L. A.; University of Wyoming ttibbets@uwyo.edu Analyses of nitrogen and carbon stable isotopes are widely used as tools in the study of food web structures and to estimate an animal�s trophic position. Most food […]
