Invasive red lionfish Pterois volitans blow directed jets of water at prey fish

Creator:: Albins, Mark A. and Lyons, Patrick J.
Abstract:: Field and laboratory observations of feeding by invasive Pacific red lionfish Pterois volitans were conducted during June through August of 2008, 2009 and 2010 near Lee Stocking Island, Bahamas. Observations of this invasive marine predator revealed a previously undocumented piscivorous behavior. While slowly approaching prey fish, lionfish produce jets of...

Hypersaline “wet patches” in Taylor Valley, Antarctica

Creator:: Levy, Joseph S., Fountain, Andrew G., Welch, Kathy A., and Lyons, W. Berry
Abstract:: Spatially isolated patches of soil located in Taylor Valley, McMurdo Dry Valleys, Antarctica, are sites of elevated salt content and soil moisture. During Antarctic spring, in the absence of snow melt, visibly wet (reduced albedo) patches of soil are present at the surface. The soil pore fluids are hypersaline and...

Deep subsurface carbon cycling in the Nankai Trough (Japan)-Evidence of tectonically induced stimulation of a deep microbial biosphere

Creator:: Riedinger, N., Strasser, M., Harris, R. N., Klockgether, G., Lyons, T. W., and Screaton, E. J.
Abstract:: The abundance of microbial life and the sources of energy necessary for deep subsurface microbial communities remain enigmatic. Here we investigate deep microbial processes and their potential relationships to tectonic events in sediments from the Nankai Trough offshore Japan, drilled and sampled during IODP (Integrated Ocean Drilling Program) Expedition 316....

Garwood Valley, Antarctica: A new record of Last Glacial Maximum to Holocene glaciofluvial processes in the McMurdo Dry Valleys

Creator:: Levy, Joseph S., Fountain, Andrew G., O'Connor, Jim E., Welch, Kathy A., and Lyons, W. Berry
Abstract:: We document the age and extent of late Quaternary glaciofluvial processes in Garwood Valley, McMurdo Dry Valleys, Antarctica, using mapping, stratigraphy, geochronology, and geochemical analysis of sedimentary and ice deposits. Geomorphic and stratigraphic evidence indicates damming of the valley at its Ross Sea outlet by the expanded Ross Sea ice...

Fine-scale variability at 140°W in the Equatorial Pacific

Creator:: Chereskin, T. K., Moum, James N., Stabeno, P. J., Caldwell, Douglas R., Paulson, C. A., Regier, L. A., and Halpern, D.
Abstract:: In November-December 1984 we carried out an intensive 12-day upper ocean sampling program on the equator at 140°W as part of the Tropic Heat Experiment. From our observations we constructed hourly averaged profiles of temperature, salinity, σ₁, turbulent kinetic energy dissipation rate, and horizontal velocity. These data were used to...

Reactor Physics Scoping and Characterization Study on Implementation of TRIGA Fuel in the Advanced Test Reactor

Creator:: Lyons, Jennifer A., Marcum, Wade R., Morrell, Sean, and DeHart, Mark
Abstract:: The Advanced Test Reactor (ATR) is conducting scoping studies for the conversion of its fuel from a highly enriched uranium (HEU) composition to a low-enriched uranium (LEU) composition, through the Reduced Enrichment for Research and Test Reactors Program, within the Global Threat Reduction Initiative. These studies have considered a wide...

Developing Nondestructive Techniques for Managing Conflicts Between Fisheries and Double-Crested Cormorant Colonies

Creator:: Suzuki, Yasuko, Roby, Daniel D., Lyons, Donald E., Courtot, Karen N., and Collis, Ken
Abstract:: Double-crested cormorants (Phalacrocorax auritus) have been identified as the source of significant mortality to juvenile salmonids (Oncorhynchus spp.) in the Columbia River Basin. Management plans for reducing the size of a large colony on East Sand Island (OR, USA) in the Columbia River estuary are currently being developed. We evaluated...

A Low-disturbance Capture Technique for Ground-nesting Double-crested Cormorants (Phalacrocorax auritus)

Creator:: Courtot, Karen N., Roby, Daniel D., Kerr, Lauren H., Lyons, Donald E., and Adkins, Jessica Y.
Abstract:: Capturing breeding adults of colonially nesting species can entail risks of nest failure and even colony abandonment, especially in species that react strongly to human disturbance. A low-disturbance technique for capturing specific adult Double-crested Cormorants (Phalacrocorax auritus) at a ground-nesting colony was developed to reduce these risks and is described...

Potential Effects of Management on Caspian Tern Hydroprogne caspia Predation on Juvenile Salmonids at a Colony in San Francisco Bay, California

Creator:: Adrean, Lindsay J., Roby, Daniel D., Lyons, Donald E., Collis, Ken, and Evans, Allen F.
Abstract:: San Francisco Bay is a proposed relocation site for some of the Caspian terns Hydroprogne caspia currently nesting at the world's largest colony for the species in the Columbia River estuary and consuming salmonids listed under the U. S. Endangered Species Act (ESA). However, several runs of salmonids listed under...

Nutritional stress affects corticosterone deposition in feathers of Caspian tern chicks

Creator:: Patterson, Allison G. L., Kitaysky, Alexander S., Lyons, Donald E., and Roby, Daniel D.
Abstract:: Stressful environmental conditions affect the adrenocortical function of developing animals, which can have consequences for their fitness. Discovery of the avian stress hormone corticosterone (CORT) in feathers has the potential to broaden the application of endocrine research in ecological and evolutionary studies of wild birds by providing a long-term measure...
