Noriyuki Yamaguchi, Jerry W. Hupp, Hiroyoshi Higuchi, Paul L. Flint, John M. Pearce
2010, Ibis (152) 262-271
We fitted Northern Pintail Anas acuta in Japan with satellite transmitters and monitored their spring migration movements relative to locations where the highly pathogenic H5N1 avian influenza virus was detected in Whooper Swans Cygnus cygnus in 2008. Pintails were assumed not to be infected with the H5N1 virus at the time they were marked...

Gregory S. Cherry, Michael F. Peck, Jaime A. Painter, Welby L. Stayton
2010, Open-File Report 2009-1275
The Upper Floridan aquifer is contaminated with saltwater in a 2-square-mile area of downtown Brunswick, Georgia. This contamination has limited development of the groundwater supply in the Glynn County area. Hydrologic, geologic, and water-quality data are needed to effectively manage water resources. Since 1959, the U.S. Geological Survey has conducted...

Robert A. Morton, Marilyn C. Montgomery
2010, Open-File Report 2010-1330
The U.S. Geological Survey (USGS) is studying coastal hazards and coastal change to improve our understanding of coastal ecosystems and to develop better capabilities of predicting future coastal change. One approach to understanding the dynamics of coastal systems is to monitor changes in barrier-island subenvironments through time. This involves examining...
Saltwater intrusion in coastal regions of North America
Paul M. Barlow, Eric G. Reichard
2010, Hydrogeology Journal (18) 247-260
Saltwater has intruded into many of the coastal aquifers of the United States, Mexico, and Canada, but the extent of saltwater intrusion varies widely among localities and hydrogeologic settings. In many instances, the area contaminated by saltwater is limited to small parts of an aquifer and to specific wells and...

The Black Oystercatcher (Haematopus bachmani) is an intertidal obligate along North America's Pacific coast and a species of high conservation concern (population size 8900–11 000 individuals). Understanding birds' movements and space use throughout the annual cycle has become paramount in the face of changing environmental conditions, and intertidal species may...
Salinity tolerance of the African Jewelfish Hemichromis letourneuxi, a non-native cichlid in South Florida (USA)
Jacqueline N. Langston, Pamela J. Schofield, Jeffrey E. Hill, William F. Loftus
2010, Copeia (2010) 475-480
The African Jewelfish (Cichlidae: Hemichromis letourneuxi) is a predatory, non-native fish that has recently (since 2000) begun to expand its geographic range across south Florida. The salinity tolerance of H. letourneuxi was unknown, and thus it was unclear whether the species could use estuarine or coastal environments. The response of H....
Scale-dependent associations of Band-tailed Pigeon counts at mineral sites
Cory T. Overton, Michael L. Casazza, Peter S. Coates
2010, Northwestern Naturalist (91) 299-308
The abundance of Band-tailed Pigeons (Patagioenas fasciata monilis) has declined substantially from historic numbers along the Pacific Coast. Identification of patterns and causative factors of this decline are hampered because habitat use data are limited, and temporal and spatial variability patterns associated with population indices are not known. Furthermore, counts...

Enumeration of viruses and prokaryotes in deep-sea sediments and cold seeps of the Gulf of Mexico
Christina A. Kellogg
2010, Deep-Sea Research Part II: Topical Studies in Oceanography (57) 2002-2007
Little is known about the distribution and abundance of viruses in deep-sea cold-seep environments. Like hydrothermal vents, seeps support communities of macrofauna that are sustained by chemosynthetic bacteria. Sediments close to these communities are hypothesized to be more microbiologically active and therefore to host higher numbers of viruses than non-seep...
