Meeting Abstract 102.3 Wednesday, Jan. 7 Developmental Evolution of the Anuran Sacrourostylic Region and its Locomotory Implications PUGENER, L. Analia; MAGLIA, Anne M.*; Missouri Univ. of Science and Technology, Rolla magliaa@mst.edu In this talk, we discuss the developmental evolution of the sacrourostylic complex of frogs as it relates to locomotion. The sacrourostylic region is one of the […]

Comparative locomotor morphology of hyloid and non-neobatrachian anurans
Meeting Abstract 102.2 Wednesday, Jan. 7 Comparative locomotor morphology of hyloid and non-neobatrachian anurans JORGENSEN, M.E.; Ohio University mj207406@ohio.edu Frogs are characterized by a unique locomotor morphology that includes (but is not limited to) a craniocaudal elongate pelvis, hindlimbs with modified tarsal elements, reduced number of pre- and postsacral vertebrae, and the presence of an urostyle. Across […]
Where Did You Get That Rhythm Plasticity in the Circatidal Swimming Behavior of Fiddler Crab Larvae
Meeting Abstract 101.1 Wednesday, Jan. 7 Where Did You Get That Rhythm? Plasticity in the Circatidal Swimming Behavior of Fiddler Crab Larvae LOPEZ-DUARTE, P.C.*; TANKERSLEY, R.A.; Scripps Institution of Oceanography; Florida Institute of Technology plopezduarte@ucsd.edu Fiddler crab Uca pugilator larvae (zoeae) possess an ebb-phased circatidal rhythm in vertical swimming that matches the period of the local tidal […]
Unscrambling the relationship between egg size and egg composition using geminate species pairs
Meeting Abstract 101.11 Wednesday, Jan. 7 Unscrambling the relationship between egg size and egg composition using geminate species pairs MCALISTER, J/S*; MORAN, A/L; Clemson University; Clemson University jmcalis@clemson.edu Egg size is one of the most important life-history parameters in marine organisms. Among species with a planktonic larval stage, egg size is strongly associated with developmental mode (planktotrophy […]
Turbidity May Provide a Protective Barrier Against Ultraviolet (UV) Light Exposure in Zebrafish (Danio rerio) Embryos
Meeting Abstract 101.3 Wednesday, Jan. 7 Turbidity May Provide a Protective Barrier Against Ultraviolet (UV) Light Exposure in Zebrafish (Danio rerio) Embryos MCFARLANE, W.J.**; DEBLASIO, H.; Manhattanville College, Purchase, NY mcfarlanew@mville.edu Exposure to ultraviolet (UV) light has been correlated to cellular damage in both human and animal models. Although UV radiation is both absorbed and scattered in […]
Sand Dolly The adaptive significance of predator-induced cloning and size reduction in Dendraster excentricus plutei
Meeting Abstract 101.6 Wednesday, Jan. 7 Sand Dolly: The adaptive significance of predator-induced cloning and size reduction in Dendraster excentricus plutei VAUGHN, D.; Univ. of Washington dvaughn@u.washington.edu Predator-induced cloning (asexual reproduction), and reduced size as a consequence of cloning, suggests a novel adaptation to the threat of predation. Although cloning is a common reproductive strategy of many […]
Role of multiple paternity in causing variation in larval growth rates in the gastropod Crepidula fornicata
Meeting Abstract 101.8 Wednesday, Jan. 7 Role of multiple paternity in causing variation in larval growth rates in the gastropod Crepidula fornicata LE CAM, Sabrina; VIARD, Frederique; CAGNON, Mathilde ; PECHENIK, Jan A.*; Station Biologique de Roscoff ; Station Biologique de Roscoff ; Station Biologique de Roscoff ; Tufts University jan.pechenik@tufts.edu The gastropod Crepidula fornicata has a […]
Reproductive correlates of exposure to ultraviolet light in an intertidal gastropod
Meeting Abstract 101.2 Wednesday, Jan. 7 Reproductive correlates of exposure to ultraviolet light in an intertidal gastropod PODOLSKY, R.D.; College of Charleston podolskyr@cofc.edu Organisms that reproduce in intertidal areas are exposed to physical stresses that could alter their reproductive behavior and output, in response to potential risks both to themselves and to their offspring. Because exposure to […]
Predator-induced changes in maternal investment in an intertidal snail
Meeting Abstract 101.7 Wednesday, Jan. 7 Predator-induced changes in maternal investment in an intertidal snail ALLEN, JD; Randolph-Macon College jonathanallen@rmc.edu Marine invertebrate animals frequently exhibit inducible morphological defenses in the presence of predators. However, few studies have investigated how adults modify reproductive behavior in the presence of predators in order to reduce mortality rates on their offspring. […]
Phenotypic plasticity in metamorphic timing Understanding the roles of size- and density-dependent processes
Meeting Abstract 101.5 Wednesday, Jan. 7 Phenotypic plasticity in metamorphic timing: Understanding the roles of size- and density-dependent processes MCCOY, M W*; WARKENTIN, K; VONESH, J R; Boston University; Boston University; Virginia Commonwealth University mwmccoy@bu.edu For organisms with complex life histories, environments encountered early in ontogeny may substantially alter densities or phenotypes transitioning into subsequent habitats. These […]
