Meeting Abstract 44.1 Saturday, Jan. 5 Morphological Analysis of Southeastern Clade Central Texas Spring and Cave Salamanders ROELKE, CE*; MEIK, JM; BENDIK, NF; GLUESENKAMP, AG; CHIPPINDALE, PT; The University of Texas at Arlington croelke@uta.edu Neotenic salamanders from central Texas in the genus Eurycea exhibit a continuum of morphological variation. The extremes of this continuum are illustrated by […]

Living Life Like There Is No Tomorrow Growth, Sex, And Death In A Remarkable Chameleon In Madagascar
Meeting Abstract 44.5 Saturday, Jan. 5 Living Life Like There Is No Tomorrow: Growth, Sex, And Death In A Remarkable Chameleon In Madagascar KARSTEN, K.B.*; ANDRIAMANDIMBIARISOA, L.N.; FOX, S.F.; RAXWORTHY, C.J.; Oklahoma State Univ.; Univ. of Antananarivo; Oklahoma State Univ.; American Museum of Natural History kris.karsten@okstate.edu For unknown reasons, the approximately 28,300 species of tetrapods almost exclusively […]
Life history evolution in Rivulus hartii interactions between predation, population density, and resource availability
Meeting Abstract 44.4 Saturday, Jan. 5 Life history evolution in Rivulus hartii: interactions between predation, population density, and resource availability WALSH, M.R.**; REZNICK, D.N.; Univ. of California, Riverside; Univ. of California, Riverside matthew.walsh@email.ucr.edu Predation is often viewed as a dominant mechanism of life history evolution. However, predators often lower population densities and increase resource levels to surviving […]
Is thermal biology the missing factor in predator-induced life history plasticity
Meeting Abstract 44.7 Saturday, Jan. 5 Is thermal biology the missing factor in predator-induced life history plasticity? ARENDT, J. D.**; STORZ, B; Univ. of California, Riverside; Florida State University, Tallahassee jarendt@ucr.edu Predation pressure induces plastic shifts in age and size at maturation in many species. Theory generally predicts early maturation at a small size in response to […]
Genetic diversity and biogeography of Symbiodinium from sea anemones, Aiptasia spp
Meeting Abstract 44.10 Saturday, Jan. 5 Genetic diversity and biogeography of Symbiodinium from sea anemones, Aiptasia spp. XIANG, Y.*; SANTOS, S.R.; Auburn University; Auburn University xiangyu@auburn.edu Symbiotic dinoflagellates in the genus Symbiodinium, commonly referred to as zooxanthellae, are single-celled protists which play important roles in the nutrition and physiology of many marine invertebrates. Recently, Symbiodinium diversity and […]
Endurance and physiology in Urosaurus ornatus sex and morph differences
Meeting Abstract 44.9 Saturday, Jan. 5 Endurance and physiology in Urosaurus ornatus: sex and morph differences? FOULKES, EC*; THAKER, M; HEWS, DK; Indiana State Univ. efoulkes@indstate.edu Locomotory performance has been the focus of many ecological and evolutionary studies, and lizards have been a model system. Less work has examined intraspecific variation in performance and suites of underlying […]
Endocrine-Mediated Evolution of Life History Traits A Study of IGF-1 and Population Divergence in the Garter Snake Thamnophis elegans
Meeting Abstract 44.2 Saturday, Jan. 5 Endocrine-Mediated Evolution of Life History Traits: A Study of IGF-1 and Population Divergence in the Garter Snake Thamnophis elegans SPARKMAN, A.M.*; BRONIKOWSKI, A.M.; Iowa State University, Ames; Iowa State University, Ames asparkma@iastate.edu The endocrine system is critically involved in the control of life history traits that underlie evolutionary fitness, and individual […]
Body size affects the expression of seasonal phenotypic plasticity thresholds, diapause length, and over winter survival in big and little flesh flies
Meeting Abstract 44.6 Saturday, Jan. 5 Body size affects the expression of seasonal phenotypic plasticity: thresholds, diapause length, and over winter survival in big and little flesh flies. HAHN, D.A.*; BUSKIRK, M.C.; University of Florida; University of Florida dahahn@ufl.edu Body size is a critical determinant of organismal life histories and physiology affecting a wide range of traits […]
Turning Mechanics in Running Goats
Meeting Abstract 43.4 Saturday, Jan. 5 Turning Mechanics in Running Goats MORENO, C.A.**; BIEWENER, A.A.; Harvard University; Harvard University cmoreno@oeb.harvard.edu Terrestrial animals frequently must execute vigorous running turns, especially during predator-prey interactions. Though this behavior is critical for survival and places extreme demands on the musculoskeletal system, the mechanics of turning are not well understood. Despite recent […]
Testing the generality of the cross-couplet locomotor system in marsupials
Meeting Abstract 43.3 Saturday, Jan. 5 Testing the generality of the cross-couplet locomotor system in marsupials REILLY, S. M.*; WHITE, T.D.; MCELROY, E.J.; Ohio University; Buffalo State College; Ohio University reilly@ohiou.edu Extant placental mammals differ from marsupials and many more basal mammalian groups in having �epipubic� bones projecting into the abdominal wall. Previously we showed that these […]
