Meeting Abstract 3.4 Thursday, Jan. 3 Could the hadrosaurs sing? A re-evaluation with new evidence FEO, T.J. ; UC Berkeley tfeo@berkeley.edu The bizarre, hollow cranial crests of the duck-billed dinosaurs (Hadrosaurinae) have had many functions attributed to them. Weishampel�s classic work showed that few of these hypotheses are testable, and that several of the testable ones can […]

Conditional Relationship between Bill Morphology and Vocal Performance in Lincoln’s Sparrows
Meeting Abstract 3.5 Thursday, Jan. 3 Conditional Relationship between Bill Morphology and Vocal Performance in Lincoln’s Sparrows SOCKMAN, K.W.; Univ. of North Carolina, Chapel Hill kws@unc.edu Individual variation in morphology can cause individual differences in behavioral performance. Although morphology affects behavior typically through a direct, physical link, in some instances the relationship may be indirectly mediated through […]
Clawing your way to the top variation, repeatability and social benefits of chela strength in slender crayfish
Meeting Abstract 3.3 Thursday, Jan. 3 Clawing your way to the top: variation, repeatability and social benefits of chela strength in slender crayfish ANGILLETTA, M. J.*; WILSON, R. S.; Indiana State Univ, Terre Haute; Univ of Queensland, St. Lucia mangilletta@indstate.edu Animals commonly signal their strength to conspecifics during disputes over resources or mates. In crayfish, such threats […]
Animal fluorescence from coral reefs to deep-sea
Meeting Abstract 3.6 Thursday, Jan. 3 Animal fluorescence: from coral reefs to deep-sea MATZ, Mikhail*; MAZEL, Charles; Univ. of Texas at Austin; Physical Sciences, Inc. matz@mail.utexas.edu Fluorescence as means of animal communication in the ocean thus far received only sporadic attention; despite that fluorescence is arguably the best way to generate a contrasting color signal in the […]
The Pleistocene Encruster Scene Comparison of Epibionts on Molluscan Shells from Different Habitats
Meeting Abstract 2.2 Thursday, Jan. 3 The Pleistocene Encruster Scene: Comparison of Epibionts on Molluscan Shells from Different Habitats VON DASSOW, YJ*; DROSER, ML; Carnegie Museum of Natural History; Univ. of California, Riverside yasmin.vondassow@gmail.com Encrusters are sessile, suspension feeding, marine organisms such as bryozoans, barnacles, and tube-building worms, that live permanently attached to a substratum. They are […]
Intrapopulation Genetic Variation Facilitates Niche Expansion
Meeting Abstract 2.3 Thursday, Jan. 3 Intrapopulation Genetic Variation Facilitates Niche Expansion AGASHE, Deepa; University of Texas, Austin deeps@mail.utexas.edu Evolutionary theory posits that adaptive potential is proportional to additive genetic variation in a population, implying that the rate and degree of adaptation to a novel environment increases with the amount of existing genetic variation for relevant traits. […]
Influence of diapause timing on the evolution of thermotolerance in Wyeomyia smithii
Meeting Abstract 2.4 Thursday, Jan. 3 Influence of diapause timing on the evolution of thermotolerance in Wyeomyia smithii RAGLAND, GJ*; KINGSOLVER, JG; University of Florida; University of North Carolina gragland@ufl.edu Tolerance of extreme temperatures is a major adaptation to seasonal environments, often exhibiting intra- and interspecific geographic variation that is correlated with environmental temperatures. Climatic data show […]

Ecological divergence in sympatric populations of the Gold-breast Splitfin, Ilyodon furcidens
Meeting Abstract 2.1 Thursday, Jan. 3 Ecological divergence in sympatric populations of the Gold-breast Splitfin, Ilyodon furcidens HUIZINGA, M.*; GHALAMBOR, C.K.; Colorado State University; Colorado State University Meribeth.Huizinga@ColoState.edu Understanding the processes that generate and maintain patterns of diversity both within and between species is a central focus of evolutionary ecology. The combined effects of natural and sexual […]
