Meeting Abstract 52.4  Jan. 6  Geographic variation and temperature-induced phenotypic plasticity of cell size in the lizard Anolis carolinensis GOODMAN, R.M.; Univ. Tennessee, Knoxville rmgoodman@utk.edu Phenotypic plasticity at the cellular level has been suggested to relate to plasticity of body size and geographic variation in body size associated with latitude and environmental temperature in ectotherms. The current […]

Meeting Abstract 52.2  Jan. 6  GENETIC VARIATION AND PHENOTYPIC PLASTICITY OF THE GORGONIAN Plexaura flexuosa IN PUERTO RICO PRADA, Carlos*; SCHIZAS, Nikolaos; YOSHIOKA, Paul; University of Puerto Rico Mayaguez cprada@cima.uprm.edu Caribbean octocorals are relatively abundant and visually dominant in low relief hard ground habitats with preference for high water motion areas. As other Anthozoans, octocorals display a […]

Meeting Abstract 52.5  Saturday, Jan. 5  Chronically elevated corticosterone inhibits mating and feeding in a Plethodontid salamander, Desmognathus ochrophaeus RICCIARDELLA, L.F.*; WOODLEY, S.K.; Duquesne University; Duquesne University ricciardellal@duq.edu In western Pennsylvania, acidified streams are common. Studies show that acidification is associated with altered stream salamander assemblages. The mountain dusky salamander, Desmognathus ochrophaeus, is an abundant local species […]
