Meeting Abstract S8-2.1  Jan. 6  Proximate Developmental Mediators of Sexual Size Dimorphism: Case Studies from Squamate Reptiles JOHN-ALDER, H.B.*; COX, R.M.; TAYLOR, E.N.; Rutgers Univ.; Ohio State Univ.; California Polytechnic State Univ., San Luis Obispo henry@aesop.rutgers.edu Sexual size dimorphism (SSD) is nearly ubiquitous in squamate reptiles, but we know very little about the relative importance of sex […]

Meeting Abstract S8-2.2  Jan. 6  Adaptation, sexual dimorphism, and ecolomorphological diversity in Caribbean Anolis lizards BUTLER, MA; University of Hawaii at Manoa mbutler@hawaii.edu Sexual dimorphism is widespread and substantial throughout the animal world. It is surprising, then, that such a pervasive source of biological diversity has not been integrated into studies of adaptive radiation, despite extensive and […]

Meeting Abstract S8-2.3  Jan. 6  Acceleration and power output in gravid green iguanas SCALES, J.A.*; BUTLER, M.A.; Univ. of Hawaii, Manoa; Univ. of Hawaii, Manoa jscales@hawaii.edu A major selective pressure for the evolution of sexual dimorphism is differential reproductive roles of the sexes (Darwin, 1871). Females of many species experience large increases in mass and volume related […]

Meeting Abstract S8-2.2  Saturday, Jan. 5  Visual elements and the evolution of the decapods PORTER, M.L.*; CRONIN, T.W.; Univ. of Maryland Baltimore County; Univ. of Maryland Baltimore County porter@umbc.edu Decapods possess a greater variety of eye types than other crustacean groups. While the evolution of this diversity has been studied in light of decapod relationships, few studies […]

Meeting Abstract S8-2.1  Saturday, Jan. 5  The bearing of larval morphology on decapod phylogeny CLARK, Paul F.*; CUESTA, Jose A.; The Natural History Museum, London; Instituto de Ciencias Marinas de Andalucia p.clark@nhm.ac.uk Traditionally, brachyuran classifications have been established on the basis of adult morphology, but all phenotypic characters are the end product of the interaction between genotype […]

Meeting Abstract S8-2.4  Saturday, Jan. 5  Parasites as Phylogenetic Indicators in Decapod Evolution BOYKO, C.B.*; WILLIAMS, J.D.; Molloy College; Hofstra University cboyko@molloy.edu The phylogenies of parasitic organisms and their hosts exhibit varying degrees of congruence based on the events their historical association (e.g., cospeciation, host switching). Comparison of two major groups of decapod parasites, the Bopyridae and […]

Meeting Abstract S8-2.3  Saturday, Jan. 5  Is Podotremata Monophyletic (Decapoda: Brachyura)? TAVARES, M.; Museum of Zoology, Sao Paulo mdst@usp.br Whether the Brachyura are monophyletic or not has long been disputed by decapodologists. One persistent problem is whether the Podotremata Guinot, 1977 (the so called primitive crabs), or part thereof, belongs to the Brachyura or not. The Podotremata […]

Meeting Abstract S8-2.4  Friday, Jan. 6  The nature of nurture and the causes of traits: toward a comprehensive theory of developmental evolution MOCZEK, Armin; Indiana University Bloomington armin@indiana.edu This presentation has three parts. First, I posit that much research in contemporary evolutionary and developmental biology, including efforts focused on developmental plasticity, remains steeped in a traditional framework […]

Meeting Abstract S8-2.2  Friday, Jan. 6  The making of a social insect – Genetics of Social Design AMDAM, GV; Arizona State University Gro.Amdam@asu.edu How do complex social systems evolve? What are the evolutionary and developmental building blocks of division of labor and specialization, the hallmarks of insect societies? In solitary insects, shifts during life history between reproductively […]

Meeting Abstract S8-2.1  Friday, Jan. 6  Genetic Contingency: Intergrating genetic background and environment into the study of mutational effects. DWORKIN, Ian; Michigan State University idworkin@msu.edu In genetic analysis, it is well known that the observed phenotype is not only a function of a given mutation, but also the influences of the genetic background in which it occurs, […]
