2003, Journal of Molluscan Studies (69) 101-106
Freshwater mussels are emersed (exposed to air) during conservation activities such as surveys and relocations. Success of these activities depends upon the ability of mussels to survive emersion and to re-burrow in the substratum. We evaluated the acute sublethal effects of emersion on three species of unionid mussels [pocketbook, Lampsilis...

Growth and condition of alewives in Lake Michigan, 1984-2001
Charles P. Madenjian, Jeffrey D. Holuszko, Timothy J. Desorcie
2003, Transactions of the American Fisheries Society (132) 1104-1116
Diets of salmonines in Lake Michigan have been dominated by alewives Alosa pseudoharengus since the 1960s, and information on alewife population dynamics is critical to the management of salmonine fisheries. We monitored alewife size at age and condition (K) at several different locations in Lake Michigan during fall 1984–2001. Alewives were aged...
Environmental fate and effects of the lampricide bayluscide: a review
Verdel K. Dawson
2003, Journal of Great Lakes Research (29 Suppl. 1) 475-492
Bayluscide is an additive to TFM that increases the effectiveness of TFM as a lampricide. A review of the literature was undertaken to determine the environmental fate and effects of Bayluscide. Niclosamide (2', 5-dichloro-4'-nitrosalicylanilide), the active ingredient of Bayluscide, degrades rapidly in natural water and sediment systems, however, the rate...

Boll weevil eradication: a model for sea lamprey control?
James W. Smith, William D. Swink
2003, Journal of Great Lakes Research (29) 445-455
Invasions of boll weevil (Anthonomus grandis) into the United States and sea lamprey (Petromyzon marinus) into the Great Lakes were similar in many ways. Important species (American cotton, Gossypium hirsutum, and lake trout, Salvelinus namaycush) and the industries they supported were negatively affected. Initial control efforts were unsuccessful until pesticides...
Wilderness experience in Rocky Mountain National Park 2002; report to respondents
Elke Schuster, S. Shea Johnson, Jonathan G. Taylor
2003, Open-File Report 2003-444
A substantial amount of backcountry (about 250,000 acres) in Rocky Mountain National Park [RMNP of the Park] may be designated as wilderness areas in the coming years. Currently, over 3 million visitors drives through the park on Trail Ridge Road, camp in designated campgrounds, day hike, etc. each year. Many...

Long term productivity of canvasbacks (Aythya valisineria) in a snowpack-driven desert marsh
Kammie L. Kruse, James R. Lovvorn, John Y. Takekawa, Jeffrey Mackay
2003, The Auk (120) 107-119
Ruby Lake, Nevada, is a large palustrine wetland that hosts the southern-most major breeding population of Canvasbacks (Aythya valisineria). That arid marsh, fed by springs derived from mountain snowpack, differs in climate and hydrology from glaciated potholes of the northern prairies where most Canvasbacks breed. Fourteen years of nesting data...
A pre-vegetated mat technique for the restoration of submersed aquatic vegetation
R.G. Boustany
2003, Ecological Restoration (21) 87-94
Communities of submersed aquatic vegetation (SAV) provide critical habitat for wintering waterfowl and many commercially important fish species. Submersed aquatic vegetation also helps minimize storm damage by reducing wave action and stabilizing sediments, and they improve water quality by sequestering nutrients and contaminants (Zieman and Zieman 1989)....

Effects of increased soil nitrogen on the dominance of alien annual plants in the Mojave Desert
Matthew L. Brooks
2003, Journal of Applied Ecology (40) 344-353
1. Deserts are one of the least invaded ecosystems by plants, possibly due to naturally low levels of soil nitrogen. Increased levels of soil nitrogen caused by atmospheric nitrogen deposition may increase the dominance of invasive alien plants and decrease the diversity of plant communities in desert regions, as it has...
Wolves: Behavior, ecology, and conservation
L. David Mech, Luigi Boitani, editor(s)
2003, Book
Wolves are some of the world's most charismatic and controversial animals, capturing the imaginations of their friends and foes alike. Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square miles in search of food. Once teetering on the brink of extinction...
Native weeds and exotic plants: relationships to disturbance in mixed grass prairie
D.L. Larson
2003, Plant Ecology (169) 317-333
The paper compares distributions of native weedy species and exotic species with respect to three kinds of disturbance, roads, trails, and prairie dog towns. Data were collected at the north and south units of Theodore Roosevelt National Park and at Wind Cave National Park. The paper concludes that many exotic...
The usefulness of GPS telemetry to study wolf circadian and social activity
Samuel B. Merrill, L. David Mech
2003, Wildlife Society Bulletin (31) 947-960
This study describes circadian and social movement patterns of 9 wolves and illustrates capabilities and limitations of Global Positioning System (GPS) telemetry for analysis of animal activity patterns. Global Positioning System telemetry was useful in determining when pack members were traveling together or apart and how long a breeding female...
Selection of flooded agricultural fields and other landscapes by female northern pintails wintering in Tulare Basin, California
Joseph P. Fleskes, Robert L. Jarvis, David S. Gilmer
2003, Wildlife Society Bulletin (31) 793-803
Habitat selection and use are measures of relative importance of habitats to wildlife and necessary information for effective wildlife conservation. To measure the relative importance of flooded agricultural fields and other landscapes to northern pintails (Anas acuta) wintering in Tulare Basin (TB), California, we radiotagged female pintails during late August-early...

Quantile regression models of animal habitat relationships
Brian S. Cade
2003, Thesis
Typically, all factors that limit an organism are not measured and included in statistical models used to investigate relationships with their environment. If important unmeasured variables interact multiplicatively with the measured variables, the statistical models often will have heterogeneous response distributions with unequal variances. Quantile regression is an approach for...

2003, Series in Remote Sensing 4-1
While ‘Fire Danger’ per se cannot be measured, the physical properties of the biotic and abiotic world that relate to fire occurrence and fire behavior can. Today, increasingly sophisticated Remote Sensing methods are being developed to more accurately detect fuel properties such as species composition (fuel...
