Hierarchical models of animal abundance and occurrence
J. Andrew Royle, R.M. Dorazio
2006, Journal of Agricultural, Biological, and Environmental Statistics (11) 249-263
Much of animal ecology is devoted to studies of abundance and occurrence of species, based on surveys of spatially referenced sample units. These surveys frequently yield sparse counts that are contaminated by imperfect detection, making direct inference about abundance or occurrence based on observational data infeasible. This article...
Monitoring for conservation
J.D. Nichols, B. Kenneth Williams
2006, Trends in Ecology and Evolution (21) 668-673
Human-mediated environmental changes have resulted in appropriate concern for the conservation of ecological systems and have led to the development of many ecological monitoring programs worldwide. Many programs that are identified with the purpose of `surveillance? represent an inefficient use of conservation funds and effort. Here, we revisit...
Passive West Nile virus antibody transfer from maternal Eastern Screech-Owls (Megascops asio) to progeny
D.C. Hahn, N.M. Nemeth, E. Edwards, P.R. Bright, N. Komar
2006, Avian Diseases (50) 454-455
Transovarial antibody transfer in owls has not been demonstrated for West Nile virus (WNV). We sampled chicks from captive adult WNV-antibody-positive Eastern Screech-Owls (Megascops asio) to evaluate the prevalence of transovarial maternal antibody transfer, as well as titers and duration of maternal antibodies. Twenty-four owlets aged 1 to...
Phosphorus amendment reduces hepatic and renal oxidative stress in mallards ingesting lead-contaminated sediments
D. J. Hoffman, G. H. Heinz, D. J. Audet
2006, Journal of Toxicology and Environmental Health, Part A (69) 1039-1053
Lead poisoning of waterfowl has been reported for decades in the Coeur d'Alene River Basin (CDARB) in Idaho as a result of the ingestion of lead-contaminated sediments. This study was conducted to determine whether the addition of phosphoric acid to CDARB sediments would reduce the bioavailability and toxicity of...
Surficial Geologic Map of the Pocasset-Provincetown-Cuttyhunk-Nantucket 24-Quadrangle Area of Cape Cod and Islands, Southeast Massachusetts
Byron D. Stone, Mary L. DiGiacomo-Cohen
2006, Open-File Report 2006-1260-E
The surficial geologic map layer shows the distribution of nonlithified earth materials at land surface in an area of 24 7.5-minute quadrangles (555 mi2 total) in southeast Massachusetts. Across Massachusetts, these materials range from a few feet to more than 500 ft in thickness. They overlie bedrock, which crops out...
Prediction of summer maximum and minimum temperature over the central and western United States: The roles of soil moisture and sea surface temperature
Eric J. Alfaro, Alexander Gershunov, Daniel R. Cayan
2006, Journal of Climate (19) 1407-1421
A statistical model based on canonical correlation analysis (CCA) was used to explore climatic associations and predictability of June–August (JJA) maximum and minimum surface air temperatures (Tmax and Tmin) as well as the frequency of Tmax daily extremes (Tmax90) in the central and western United States (west of 90°W). Explanatory...
An interface between the Agricultural Non-Point Source (AGNPS) pollution model and the ERDAS Imagine Geographic Information System (GIS)
Michael P. Finn, E. Lynn Usery, Douglas J. Scheidt, Gregory M. Jaromack, Timothy D. Krupinski
2006, Geographic Information Sciences (12) 10-20
The U.S. Department of Agriculture developed the Agricultural Non-Point Source (AGNPS) pollution model. The AGNPS pollution model simulates the behavior of runoff, sediment, and nutrient transport from watersheds that have agriculture as their prime use. This model has been used extensively by scientists conducting hydrologic or water quality analyses using...

Head-bobbing behavior in foraging Whooping Cranes
T. Cronin, M. Kinloch, Glenn H. Olsen
2006, Book chapter, Abstracts to XXIV International Ornithological Congress, Hamburg, 2006
Many species of cursorial birds 'head-bob', that is, they alternately thrust the head forward, then hold it stiII as they walk. Such a motion stabilizes visual fields intermittently and could be critical for visual search; yet the time available for stabilization vs. forward thrust varies with walking speed....

Atlantic Seaduck Project is being conducted to learn more about the breeding and moulting areas of seaducks in northern Canada and more about their feeding ecology on wintering areas, especially Chesapeake Bay. Satellite telemetry is being used to track surf scoters wintering in Chesapeake Bay, Maryland and black scoters...
Risky business: Site selection by Acadian Flycatchers under threat of nest predation and brood parasitism
K.R. HazIer, R.J. Cooper, D.J. Twedt
2006, Book chapter, Abstracts to XXIV International Ornithological Congress, Hamburg, 2006
Habitat quality is determined not only by habitat structure and the availability of resources, but also by competitors, cooperators, predators, and parasites. We hypothesized that, for passerines, minimizing risk from avian nest predators and brood parasites is an important factor in selecting a breeding site. Through the early...
Five years (2000-2004) of post-reconstruction monitoring of freshwater tidal wetlands in the urban Anacostia River, Washington, D.C. USA

The Anacostia River in Washington, D.C. USA consisted of over 809 hectares (2000 acres) of freshwater tidal wetlands before mandatory dredging removed most of them in the first half of the 20th century. Much of this13 kilometer (8 mile) reach was transferred to the National Park Service (NPS)....

Determining the degree of connectivity between breeding and wintering populations is critical for understanding the ecology and evolution of migratory systems. We analyzed stable hydrogen isotopic compositions in tail feathers ($Dw) collected from 26 sites in 11 countries throughout the wintering range of the American Redstart (Setophaga ruticilla), a...

Effects of methyl mercury on reproduction in American kestrels

2006, Book chapter, Eighth International Conference on Mercury as a Global Pollutant, Madison, WI, 6-11 August, 2006, Abstract CD.
Methyl mercury (MeHg) readily passes through biological membranes, accumulates in individuals, and biomagnifies in higher order predators. It is acutely toxic to some birds at 5-15 parts per million (ppm) wet weight in the diet, and it can damage the central nervous system, impair reproduction, and retard growth and...
Adaptive harvest management of North American waterfowl populations - recent successes and future prospects

2006, Book chapter, XXIV International Ornithological Congress, Hamburg, 2006, Abstracts
The history of North American waterfowl harvest management has been characterized by attempts to use population monitoring data to make informed harvest management decisions. Early attempts can be characterized as intuitive decision processes, and later efforts were guided increasingly by population models and associated predictions. In 1995, a...

We analyzed characteristics of wetland habitats used by breeding black scoters (Melanitta nigra) and surf scoters (M. perspicillata) in the eastern boreal forest and subarctic regions of Canada based on satellite telemetry data collected in the spring and summer. During 2002 and 2004, nine black scoters (four males, five...

2006, Book chapter, Northwestern Hawaiian Islands Third Scientific Symposium. November 2-4, 2004
The effects of fishery practices on black-footed (Phoebastria nigripes) and Laysan albatross (Phoebastria immutabilis) continue to be a source of contention and uncertainty. Some of this uncertainty is a result of a lack of estimates of albatross demographic parameters such as survival. To begin to address these informational...
Impacts of marsh management on coastal-marsh bird habitats
L.R. Mitchell, S. Gabrey, P.P. Marra, R.M. Erwin
2006, Book chapter, Terrestrial vertebrates of tidal marshes: evolution, ecology, and conservation
The effects of habitat-management practices in coastal marshes have been poorly evaluated. We summarize the extant literature concerning whether these manipulations achieve their goals and the effects of these manipulations on target (i.e., waterfowl and waterfowl food plants) and non-target organisms (particularly coastal-marsh endemics). Although we focus on...
