SELBY, M.S.*; RENO, P.L.; MCCOLLUM, M. A.; LOVEJOY, C. O; Kent State University; Kent State University; Mercer College; Kent State University: Is colobine thumb reduction pleiotropic? Colobines typically have shorter thumbs and longer posterior digits than cercopithecines. Functional explanations for thumb reduction in Colobus include reducing thumb interference during forelimb-first landings. However, colobine digit elongation […]

Intertidal oyster reefs impacted by recreational boating effects on reef structure and biodiversity
STINER, J. S.*; WALTERS, L. J.; University of Central Florida: Intertidal oyster reefs impacted by recreational boating: effects on reef structure and biodiversity Widely regarded as a keystone species and ecosystem engineer, the eastern oyster Crassostrea virginica plays a vital role in estuarine environments. Complex three-dimensional oyster reefs act as havens for biodiversity. Recently, concern […]
Inter-specific differences between larval American Bullfrog (Rana catesbeiana) and Southern Leopard Frog (Rana sphenocephala) susceptibility to Batrachochytri
PETERSON, J.D.; WOOD, M.B.*; HOPKINS, W.A.; MENDONCA, M.T.; Auburn University; Auburn University; Virginia Polytechnic Institute and State University; Auburn University: Inter-specific differences between larval American Bullfrog (Rana catesbeiana) and Southern Leopard Frog (Rana sphenocephala) susceptibility to Batrachochytrium dendrobatidis infection within a contaminated wetland on the Savannah River Site, South Carolina Although numerous amphibian populations, world-wide, […]
Intact Teleostian Ovarian Follicles as a Potential Detector of Endocrine Disrupting Chemicals and an Undergratuate Level Teaching Tool
JENSEN, BH; PULICE, E*; The College of Saint Rose, Albany, NY; The College of Saint Rose, Albany, NY: Intact Teleostian Ovarian Follicles as a Potential Detector of Endocrine Disrupting Chemicals and an Undergratuate Level Teaching Tool Many undergraduate science labs rely predominantly on laboratory demonstrations rather than student-designed experimentation. We are currently working to provide […]
Insects of the Sea A Morphological Analysis of Copepod Evolution and Development
ARMGARDT, Emily, T. ; Seattle University: Insects of the Sea: A Morphological Analysis of Copepod Evolution and Development Copepods are found in nearly all aquatic and marine habitats, yet little is known about their embryonic development. Using the phosphorescent stains phalloidin, DAPI, and propidium iodide, the early development of musculature in two harpactoicid copepods, Tigriopus […]
Ingestion rates on natural and artificial particles by pacific echinoderm larvae
GEORGE, S. B.*; FOX, C. A.; Georgia Southern University: Ingestion rates on natural and artificial particles by pacific echinoderm larvae Ingestion rates of the seastars Dermasterias imbricata (larval size:1201-1492µm), Pisaster ochraceus (1613-1799µm), and Evasterias troschelii (1356-1624µm), the sea urchin, Strongylocentrotus purpuratus (348-807µm) and the sand dollar Dendraster excentricus (534-731µm) were investigated in the laboratory using […]
Immunolocalization of Na+K+ pump in the branchial cavity of Palaemon elegans (Decapoda, Crustacea) and effects of mercury on Na+,K+-ATPase immunoreactivity
KHODABANDEH, Saber*; GHOLZARI, Alaleh; Tarbiat Modarres University; Tarbiat Modarres University: Immunolocalization of Na+/K+ pump in the branchial cavity of Palaemon elegans (Decapoda, Crustacea) and effects of mercury on Na+,K+-ATPase immunoreactivity The monoclonal antibody IgG-alpha5 have been widely to identify Na+/K+ pump. Ultrastructure, Na+/K+ pump localization, and effects of mercury on Na+,K+-ATPase immunoreactivity were investigated in […]
Identifying Sex in Juvenile and Immature Gopher Tortoises Gopherus polyphemus, a Species with Delayed Sexual Maturation
WOODS, Caroline S.*; ROSTAL, David C.; Georgia Southern University: Identifying Sex in Juvenile and Immature Gopher Tortoises Gopherus polyphemus, a Species with Delayed Sexual Maturation The presence of temperature-dependent sex determination and the delayed expression of secondary sex characteristics (13 to 20 years) in gopher tortoises have made determining population demographics difficult. The use of […]
How do migrants respond to prolonged migratory restlessness
RAMENOFSKY, M.**; MOFFAT, J.; COVERDILL, A.J.; BENTLEY, G.E.; University of Washington, Seattle; University of Washington, Seattle; University of Washington, Seattle; University of California, Berkeley: How do migrants respond to prolonged migratory restlessness? Migratory flight is energetically costly yet birds fly for great distances crossing diverse barriers. Long distance, short-bout migrants like white-crowned sparrows (Zonotrichia leucophrys […]
Historical Phylogeny of Tahitian Partula
LEE, T.*; BURCH, J. B.; � FOIGHIL, D.; Univ. of Michigan; Univ. of Michigan; Univ. of Michigan: Historical Phylogeny of Tahitian Partula Oceanic islands hold particular interest for both evolutionary and conservation biologists. Native plants and animals evolved in isolation on these islands and provide detailed insights into fundamental evolutionary processes. However, they characteristically lack […]
