Meeting Abstract P3.185  Friday, Jan. 6  Morphology, ecology, and reproduction of the cryptogenic sponge associate Polydora colonia (Polychaeta: Spionidae) WILLIAMS, Jason*; DAVID, Andrew; Hofstra University; Hofstra University biojdw@hofstra.edu The spionid polychaete Polydora colonia (Moore 1907) is a widely distributed polydorid worm, typically found associated with sponges. The species was first described from Massachusetts and has been reported […]

Meeting Abstract P3.184  Friday, Jan. 6  Modulation of leech muscle performance by serotonin FEILICH, KL*; GERRY, SP; ELLERBY, DJ; Wellesley College dellerby@wellesley.edu The obliquely striated muscle in the leech body wall has a broad functional repertoire; it provides power for both locomotion and suction feeding. Increased serotonin (5-HT) levels promote these behaviors and also affect muscle mechanical […]

Meeting Abstract P3.88  Friday, Jan. 6  Modification of velar lobe morphology across different developmental modes in Calpytraeid gastropods HOFSTEE, J.C.*; COLLIN, R.; Smithsonian Tropical Research Institute jeanettehofstee@gmail.com Mode of development in marine invertebrates can include planktotrophic larvae, lechithotrophic larvae, direct development from large eggs and direct development with nurse eggs. It is generally believed that evolutionary changes […]

Meeting Abstract P3.100  Friday, Jan. 6  Modeling feeding biomechanics of the asymmetrical flatfish Paralichthys lethostigma HENSON, C.B.*; FRANCIS, JR., A.W.; Armstrong Atlantic State Univ., Savannah, GA ch3866@stu.armstrong.edu The vast majority of bony fishes are characterized as being symmetrical morphologically, and due to this, most observations can be made solely from the sinistral side. However, flatfishes (Order Pleuronectiformes) […]

Meeting Abstract P3.103  Friday, Jan. 6  Mobility of the mandibular symphysis during feeding in lizards MONTUELLE, S.J.*; WILLIAMS, S.H.; Ohio University Heritage College of Osteopathic Medicine; Ohio University Heritage College of Osteopathic Medicine montuell@ohio.edu In jawed vertebrates, the lower jaw is comprised of two hemimandibles that are united in the anterior midline by the mandibular symphysis. In […]

Meeting Abstract P3.148  Friday, Jan. 6  Middle Ear Cavity Morphology Across Testudines WILLIS, Katie L*; CARR, Catherine E; Univ of Maryland; Univ of Maryland kwillis@umd.edu We hypothesize that the function of the large middle ear cavity in testudines is to act as a resonator for underwater sound. To determine if middle ear cavity size was affected by […]

Meeting Abstract P3.198  Friday, Jan. 6  Microsatellite Variation in Invasive and Native Populations of the Centaurea Leafcutting Bee HRANITZ, J.M.*; BARTHELL, J.F.; SULLIVAN, N.; RICCI, P.R.; Bloomsburg University of Pennsylvania; University of Central Oklahoma; Bloomsburg University of Pennsylvania; Bloomsburg University of Pennsylvania jhranitz@bloomu.edu The Centaurea leafcutting bee (Megachile apicalis) is an invasive solitary bee and an established […]

Meeting Abstract P3.27  Friday, Jan. 6  Microcosm tests of interspecific competitive abilities and habitat monopolization WALSH, E.J.*; WOODS, M.A.; SCHROEDER, T.; Univ. of Texas, El Paso; Univ. of Texas, El Paso; Univ. of Texas, El Paso ewalsh@utep.edu The Monopolization Hypothesis states that if a species establishes itself in an environment then other species will not be able […]

Meeting Abstract P3.115  Friday, Jan. 6  Metabolic carryover effects in postmetamorphic red-eyed treefrogs WARGELIN, L.W.*; BOUCHARD, S.S.; WARKENTIN, K.M.; Otterbein University; Otterbein University; Boston University lindsay.wargelin@otterbein.edu Resource availability has a strong effect on growth and development. Low food levels reduce larval growth rates and, in anurans, can delay metamorphosis dramatically. There may also be important metabolic implications, […]

Meeting Abstract P3.177  Friday, Jan. 6  Mechanical properties of the skin of the Pacific hagfish, Epatretus stoutii DEMAS, A/D*; CLARK, A/J; College of Charleston; College of Charleston amdemas@g.cofc.edu Hagfishes possess minimal tendinous connections between the skin and axial muscles that power locomotion, which gives their skin a loose-fitting appearance. This contrasts the tighter-fitting skin in lampreys, cartilaginous […]
