Meeting Abstract P1.106  Jan. 4  Proliferation, differentiation and survival of newborn cells in adult amphibian brains SAIJO, E.*; ORCHINIK, M.; School of Life Sciences, Arizona State Univ m.orchinik@asu.edu To understand the regulatory mechanisms and importance of naturally-occurring adult neurogenesis in vertebrates, we are investigating neurogenesis in adult bullfrogs (Rana catesbeiana). In previous studies, we found widespread cell […]

Meeting Abstract P1.132  Jan. 4  Preliminary Molecular Phylogeny of the Tilefishes JIMENEZ, L.*; DOOLEY, J K.; Adelphi University; Adelphi University jimenez2@adelphi.edu Tilefishes are found in the Atlantic, Pacific, and Indian Oceans. The five genera of tilefishes consist of forty-two nominal species. The classification of the tilefishes has experienced a number of revisions since they were first placed […]

Meeting Abstract P1.81  Jan. 4  Potential molecular basis for lower salinity limits in the euryhaline green crab, Carcinus maenas HENRY, R.P.; Auburn University henryrp@auburn.edu The green crab, Carcinus maenas, is a euryhaline marine crustacean that is found in salinities as low as 10 ppt. It can be acclimated to as low as 5 ppt, but this is […]

Meeting Abstract P1.115  Jan. 4  Plasticity in Lek Spatial Dynamics in Gryllotalpa major Saussure (Orthoptera: Gryllotalpidae): The Influence of Above-ground Botanical Biomass and Grass Height on Male Spacing. HOWARD, D.R.; University of Tulsa, Oklahoma daniel-howard@utulsa.edu The prairie mole cricket (Gryllotalpa major Saussure) is a threatened orthopteran insect of the tallgrass prairie ecosystem of the south central United […]

Steven; GREEN, David M.; Central Washington University, Ellensburg, WA; Central Washington University, Ellensburg, WA; Central Washington University, Ellensburg, WA; Central Washington University, Ellensburg, WA; Redpath Museum, […]

Meeting Abstract P1.137  Jan. 4  Phylogenies, adaptation, and the comparative method BUTLER, MA; University of Hawaii at Manoa mbutler@hawaii.edu I examine evolutionary models for studying evolutionary hypotheses of adaptation using OUCH! “Ornstein-Uhlenbeck for Comparative Hypotheses”. Previously, we developed a direct-modeling approach to study the evolution of a single quantiative character using a phylogenetic tree. We varied the […]

Meeting Abstract P1.129  Jan. 4  Phylogenetic Relationships among Unionicola Mussel-Mites: Inferences from Morphological and Molecular Characters EDWARDS, D.D.*; ERNSTING, B.R.; VIDRINE, M.F.; Univ. of Evansville; Univ. of Louisiana, Eunice de3@evansville.edu North American water mites of the genus Unionicola commonly occur in parasitic association with freshwater mussels, living on the gills or mantle and foot of their hosts. […]

Meeting Abstract P1.125  Jan. 4  Phylogenetic Analysis of Terebelliformia Worms (Polychaeta, Annelida) based on mitochondrial genomes ZHONG, M*; HALANYCH, K M.; Auburn University; Auburn University zhongmi@auburn.edu Complete mitochondrial genome (mtDNA) seqeunces are a useful tool for inferring animal phylogeny. Because the rate of gene arrangement of mtDNA varies among different lineages, gene order may provide resolution at […]

Meeting Abstract P1.12  Jan. 4  Phallic development in a sexually temperature dependent sensitive vertebrate BRYAN, Teresa A*; GUILLETTE, Louis J.; University of Florida; University of Florida tbryan@zoo.ufl.edu The development of external genitalia in vertebrates has been poorly studied until rather recently. A number of studies have demonstrated that the development of the vertebrate phallus appears to occur […]
