Morphological Analysis of Southeastern Clade Central Texas Spring and Cave Salamanders

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 […]

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 […]
