Effect of climate fluctuations on long-term vegetation dynamics in Carolina bay wetlands
C.L. Stroh, D. De Steven, G.R. Guntenspergen
2008, Wetlands (28) 17-27
Carolina bays and similar depression wetlands of the U.S. Southeastern Coastal Plain have hydrologic regimes that are driven primarily by rainfall. Therefore, climate fluctuations such as drought cycles have the potential to shape long-term vegetation dynamics. Models suggest two potential long-term responses to hydrologic fluctuations, either cyclic change...
Sediment ingestion rates in waterfowl (Anatidae) and their use in environmental risk assessment
W. Nelson Beyer, Matthew C. Perry, Peter C. Osenton
2008, Integrated Environmental Assessment and Management (4) 246-251
When waterfowl (Anatidae) ingest sediment as they feed, they are exposed to the environmental contaminants in those sediments. The rate of ingestion may be key to assessing environmental risk. Rates of sediment ingestion were estimated as from <2% to 22% in 16 species of waterfowl collected in the northeastern United...
The Overmyer mastodon (Mammut americanum) from Fulton County, Indiana
Neal Woodman, J. W. Branstrator
2008, American Midland Naturalist (159) 125-146
In June 1978 the partial skeleton of an American mastodon, Mammut americanum, was salvaged from a drainage ditch in Fulton County, north-central Indiana. The remains were recovered mostly from ca. 170–260 cm below the current land surface in marl overlain by peat and peaty marl. The stratigraphy of the site...
Freeze-frame fruit selection by birds
Mercedes S. Foster
2008, Wilson Journal of Ornithology (120) 901-905
The choice of fruits by an avian frugivore is affected by choices it makes at multiple hierarchical levels (e.g., species of fruit, individual tree, individual fruit). Factors that influence those choices vary among levels in the hierarchy and include characteristics of the environment, the tree, and the fruit itself....
Hierarchical modeling of cluster size in wildlife surveys
J. Andrew Royle
2008, Journal of Agricultural, Biological, and Environmental Statistics (13) 23-36
Clusters or groups of individuals are the fundamental unit of observation in many wildlife sampling problems, including aerial surveys of waterfowl, marine mammals, and ungulates. Explicit accounting of cluster size in models for estimating abundance is necessary because detection of individuals within clusters is not independent and detectability of...

L.O. Park, J. L. Marion, R.E. Manning, S.R. Lawson, C. Jacobi
2008, Journal of Park and Recreation Administration (26) 97-121
How can recreation use be managed to control associated environmental impacts? What management practices are most effective and why? This study explored these and related questions through a series of experimental ?treatments? and associated ?controls? at the summit of Cadillac Mountain in Acadia National Park, a heavily used...
Variability in triactinomyxon production from Tubifex tubifex populations from the same mitochondrial DNA lineage infected with Myxobolus cerebralis, the causative agent of whirling disease in salmonids
C. Rasmussen, J. Zickovich, J. R. Winton, B.L. Kerans
2008, Journal of Parasitology (94) 700-708
Myxobolus cerebralis, the causative agent of whirling disease, infects both salmonid fish and an aquatic oligochaete, Tubifex tubifex. Although M. cerebralis has been detected in river drainages throughout the United States, disease severity among wild fish populations has been highly variable. Tubifex tubifex populations have been genetically characterized using sequences...

2008, Scientific Investigations Report 2009-5226
This report depicts potentiometric surfaces and groundwater- level changes in three aquifers that underlie the seven-county Twin Cities Metropolitan Area. Approximately 350 groundwater levels were measured in wells from the three aquifers-the Prairie du Chien-Jordan, the Franconia-Ironton-Galesville, and the Mount Simon-Hinckley aquifers-in March and August of 2008. The report presents...
Population dynamics of the Concho water snake in rivers and reservoirs
M.J. Whiting, J.R. Dixon, B.D. Greene, J.M. Mueller, O.W. Thornton Jr., Jeff S. Hatfield, J.D. Nichols, J.E. Hines
2008, Copeia (2008) 438-445
The Concho Water Snake (Nerodia harteri paucimaculata) is confined to the Concho–Colorado River valley of central Texas, thereby occupying one of the smallest geographic ranges of any North American snake. In 1986, N. h. paucimaculata was designated as a federally threatened species, in large part because of reservoir projects that...
Electrical characterization of non‐Fickian transport in groundwater and hyporheic systems
Kamini Singha, Adam Pidlisecky, Frederick D. Day-Lewis, Michael N. Gooseff
2008, Water Resources Research (44)
Recent work indicates that processes controlling solute mass transfer between mobile and less mobile domains in porous media may be quantified by combining electrical geophysical methods and electrically conductive tracers. Whereas direct geochemical measurements of solute preferentially sample the mobile domain, electrical geophysical methods are sensitive to changes in bulk...

2008, Book chapter, Tundra to Tropics: Connecting Birds, Habitats and People: 4th International Partners in Flight Conference, 13-16 February 2008, McAllen, Texas: Abstracts
We describe a survey design and field protocol for the Ivory-billed Woodpecker (Campephilus principalis) search effort that will: (1) allow estimation of occupancy, use, and detection probability for habitats at two spatial scales within the bird?s former range, (2) assess relationships between occupancy, use, and habitat characteristics at those scales,...
Bird response to silviculture induced change in forest structure within bottomland hardwood forests
D.J. Twedt, S.G. Somershoe
2008, Book chapter, Tundra to Tropics: Connecting Birds, Habitats and People: 4th International Partners in Flight Conference, 13-16 February 2008, McAllen, Texas: Abstracts
Silvicultural treatments prescribed to encourage development of desired stand structure (i.e., wildlife-forestry) should result in increased abundance of many bird species of management concern, especially species using dense understory habitat. Desired forest conditions within bottomland vary among sites, but average 60-70% overstory canopy that is heterogeneously distributed with >5...
Ticks
H. S. Ginsberg, M.K. Faulde
2008, Book chapter, Public Health Significance of Urban Pests
The most common vector-borne diseases in both Europe and North America are transmitted by ticks. Lyme borreliosis (LB), a tick-borne bacterial zoonosis, is the most highly prevalent. Other important tick-borne diseases include TBE (tick-borne encephalitis) and Crimean-Congo haemorrhagic fever in Europe, Rocky Mountain spotted fever (RMSF) in North...

2008, Book chapter, Tundra to Tropics: Connecting Birds, Habitats and People: 4th International Partners in Flight Conference, 13-16 February 2008, McAllen, Texas: Abstracts
The Rusty Blackbird (Euphagus carolinus), a formerly common breeding species of boreal wetlands, has exhibited the most marked decline of any North American landbird. North American Breeding Bird Survey (BBS) trends in abundance are estimated to be -12.5% / yr over the last 40 years, which is tantamount to...

William E. Davis Jr., Jerome A. Jackson, John Tautin, editor(s)
2008, Book chapter, Bird Banding in North America: The First Hundred Years
Early bird-banding programs in North America were developed to provide descriptions of bird migration and movement patterns. This initial interest in description quickly evolved into more quantitative interests in two ways. There was (1) interest in quantifying migration and movement patterns, and (2) rapid recognition that re-observations of marked...
