LANDYS, M.M.*; DECENCIERE, B.; GOYMANN, W.; SLAGSVOLD, T.; Univ. of Oslo; Univ. of Oslo; Max Planck Institute for Ornithology, Andechs; Univ. of Oslo: Effects of cross-fostering on territorial aggression and plasma testosterone in the blue tit: testing the �challenge hypothesis� Gonadal testosterone plays an important role in the support of territorial aggression in many breeding […]

SLOAN, N. J.B.*; GOODFRIEND, E.; JOHNSON, K.B.; Florida Institute of Technology: Zooplankton Abundance and Distribution in Tidal Marshes Impounded for Mosquito Control Seventy-five percent of tidal marsh areas along the Indian River Lagoon (IRL) are impounded for mosquito control. Canals within these areas are habitat used as nurseries by juvenile fish, which in many cases […]

ROTH, J.D.*; WIESEL, I.; DREA, C.M.; University of Central Florida; Brown Hyena Research Project, Namibia; Duke University: Variation in seal consumption by brown hyenas in the Namib desert estimated using stable isotopes Coastal areas often receive substantial inputs of energy and nutrients from the ocean, and these allochthonous inputs can be important for terrestrial consumers. […]

FAUTH, J.E.*; OLESON, R.; KAUP, D.J.; MALONE, L.C.; CLARKE, T.L.; University of Central Florida (UCF); UCF; UCF; UCF; UCF: Using crowd-control simulations to predict the behavior of motile organisms Simulation is being used to develop crowd-control models to understand the collective behavior of pedestrians in the street or of people finding their way out of […]

CATENAZZI, Alessandro; Florida International University: The Ulva connection: marine resources subsidize terrestrial consumers in coastal Peru How can terrestrial animals survive in a desert with scant primary productivity? The Peruvian coastal desert is hyper-arid, but faces one of the most productive marine ecosystems, the Peru-Chile cold current. Given the stark difference in productivity between these […]

WILLIAMS, R. L.*; JOHNSON, K. B.; University of South Florida; Florida Institute of Technology: Seasonal Variation, Diet and Prey Selection of the Ctenophore Mnemiopsis leidyi in a Subtropical Estuary Published studies suggest mechanisms controlling blooms of the ctenophore Mnemiopsis leidyi vary relative to latitude and, in some estuaries, their presence reduces zooplankton standing stocks. It […]

BARTON, B. T.*; ROTH, J. D.; Yale University; University of Central Florida: Sea turtle nest predators: Implications for community ecology All four species of marine turtle that nest in Florida are listed as threatened or endangered under the Endangered Species Act of 1973, requiring actions to protect and restore these species. Raccoon (Procyon lotor) predation […]

MCCOY, Michael W*; BOLKER, Ben; OSENBERG, Craig; University of Florida; University of Florida; University of Florida: Predator induced phenotypic plasticity: influence of prey size, density, and experience Adaptive phenotypic plasticity in response to predators has been documented for many organisms. However, most studies have only examined the phenotypic responses of organisms of a single size […]

Nevada, Las Vegas; Arizona State University; Univ. of Stellenbosch, South Africa; Univ. of Otago, New Zealand; Univ. of Stellenbosch, South Africa: Physiological constraints on the small-scale distribution of three species of Antarctic Collembola We investigated the tolerance to cold, heat and desiccation of three […]

BELDEN, L.K.; Virginia Tech: Impact of euthrophication on wood frog tadpoles infected with trematode cercariae Global environmental changes are likely to have profound impacts on disease dynamics in natural systems. To make predictions about what specific impacts are expected, one thing we need is a solid understanding of how the environmental context of host-parasite interactions […]
