Meeting Abstract 13.1 Jan. 4 Reversed polarity budding in the basal bilaterian Convolutriloba retrogemma (Acoelomorpha: Acoela) SIKES, James M.*; BELY, Alexa E.; University of Maryland jsikes@umd.edu The acoel Convolutriloba retrogemma reproduces by a remarkable budding process in which two posterior buds are formed that have a reversed A/P polarity relative to the parent. To investigate the evolution […]

Myodocopid ostracods (Crustacea) as models for studies of eye evolution
Meeting Abstract 13.4 Jan. 4 Myodocopid ostracods (Crustacea) as models for studies of eye evolution RIVERA, Ajna S.*; OAKLEY, Todd H.; Univ of California, Santa Barbara; Univ of California, Santa Barbara arivera@lifesci.ucsb.edu Ostracod crustaceans are a valuable group for studying evolutionary biology in general, and developmental constraints on evolution in particular. Contrary to previous ideas concerning eye […]
INTEGRATING PALEOBIOLOGY AND DEVELOPMENTAL GENETICS CONTRIBUTIONS OF THE FOSSIL RECORD TO THE STUDY OF FIN LOSS IN TELEOST FISH
Meeting Abstract 13.3 Jan. 4 INTEGRATING PALEOBIOLOGY AND DEVELOPMENTAL GENETICS: CONTRIBUTIONS OF THE FOSSIL RECORD TO THE STUDY OF FIN LOSS IN TELEOST FISH SANTINI, Francesco*; CARNEVALE, Giorgio; University of Toronto; University of Pisa francesco.santini@utoronto.ca With over 28000 species, teleost fish represent the largest vertebrate clade. Most teleosts rely on the movement of a combination of paired […]

Meeting Abstract 13.5 Jan. 4 Development of the nervous system in Nematostella vectensis, an anthozoan cnidarian MARLOW, H.**; MATUS, D.Q.; MARTINDALE, M.Q.; Kewalo Marine Laboratory, University of Hawaii; Kewalo Marine Laboratory, University of Hawaii; Kewalo Marine Laboratory, University of Hawaii marlow@hawaii.edu Due to their phylogenetic position as sister taxa to the bilateria, as well as their reportedly […]
Development of the facultatively planktotrophic echinoid Clypeaster rosaceus
Meeting Abstract 13.2 Jan. 4 Development of the facultatively planktotrophic echinoid Clypeaster rosaceus ZIGLER, Kirk S.; Sewanee: The University of the South kzigler@sewanee.edu We studied the cell lineage and egg energetics of Clypeaster rosaceus, a facultatively planktotrophic echinoid from the Caribbean. We also compared C. rosaceus egg energy with its sympatric congener C. subdepressus, an obligate planktotroph, […]

L.*; MACEDONIA, J. ; KEMP, D. ; TAYLOR-TAFT, L.; Arizona State University r.rutowski@asu.edu In some species of sulphur butterflies (Pieridae: Coliadinae) females as well as males display bright structural reflectance on their dorsal wing surfaces, although comparatively little attention has been […]
The role of temporal properties of the advertisement calls in the phonotactic response of territorial Allobates femoralis (Anura Dendrobatidae) males
Meeting Abstract 12.2 Jan. 4 The role of temporal properties of the advertisement calls in the phonotactic response of territorial Allobates femoralis (Anura: Dendrobatidae) males VELEZ, A*; AMEZQUITA, A; University of Minnesota; Universidad de Los Andes velez011@umn.edu Among anuran amphibians advertisement calls are used to attract females and repel other males. Territorial species most commonly defend their […]

Meeting Abstract 12.6 Jan. 4 Female response behavior to complex, intermittent luminescent male displays in a Caribbean ostracod. RIVERS, TJ*; MORIN, JG; Cornell University; Cornell University tjr28@cornell.edu Although bioluminescence is much more prevalent in marine environments than terrestrial ones, describing female response behavior in mating systems where males utilize distinct, species-specific luminescent courtship displays to attract females […]
