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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

SHOWALTER, Ann M*; BURNAFORD, Jennifer L; University of Puget Sound; University of Puget Sound: Habitat selection and predation pressure of the seastar Leptasterias hexactis In complex communities, predation from top trophic levels can determine the distribution patters of lower-level organisms. Microhabitat selection by predators could affect prey distribution in a patchy manner, if predation is […]
