Impediments To And Opportunities For Fulfillment Of The Rational Comprehensive Intent Of The National Environmental Policy Act, Brian P. Mcmullen
Impediments To And Opportunities For Fulfillment Of The Rational Comprehensive Intent Of The National Environmental Policy Act, Brian P. Mcmullen
Community and Regional Planning Program: Theses
The National Environmental Policy Act of 1960 (NEPA) initiated the study and practice of environmental impact analysis. Upon passage, NEPA transformed the process in which the federal government plans, seeks input on, and documents major projects of environmental significance. While NEPA has surely affected project-level incremental actions, its rational comprehensive mandate as expressed in Title II of the statute has remained largely unfulfilled. Neglect of Title II has occurred as a result of broad language in NEPA that is difficult for federal judges to interpret and administrators to implement. Political interference with the President’s Council on Environmental Quality (CEQ) has …
Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis
Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis
United States National Park Service: Publications
Abstract
In the tallgrass prairie region of North America, grasslands are often burned on a rotational schedule to prevent the encroachment of woody species and maintain the vigor of plant communities. Although prescribed fire practitioners often consider the effects of fire on plant communities, the effects of fire on wildlife are also important. Practitioners as well as park visitors inquire about the effects of fire on birds, deer, and other animals of interest. Many wildlife species focus on vegetation structure in choosing suitable habitats, and fire can temporarily alter that structure. Wildlife species have varying habitat needs, and therefore, a …

Executive Summary
The condition of natural resources in parks and other units of the National Park Service (NPS) is fundamental to this agency’s mission to manage park resources “unimpaired for the enjoyment of future generations.” Park managers are increasingly confronted with complex and challenging resource management issues and need a broad-based understanding of the status and trends of park resources for the long-term protection of park ecosystems. The National Park Service has initiated a long-term ecological “Vital Signs” monitoring program to provide the minimum infrastructure needed to track the overall condition of natural resources in parks and to provide early …
Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller
Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller
United States National Park Service: Publications
Abstract
In this study, Miller re-analyzed acoustic bat data collected from June-August 2003 that was part of a baseline inventory of bat species in three national parks in the Lake Superior region. While the original study presented base-line data on the presence/absence of bat species in these parks, this reanalysis provides estimates of relative abundance and temporal activity of the identified species. Using a suite of recently developed acoustic analysis tools, Miller created species specific filters. This allowed parsing of calls from non-fragmented sequences and differentiate between two species, Myotis septentrionalis and Myotis lucifugus, that were combined into a …

Migration Of Northern Yellowstone Elk: Implications Of Spatial Structuring, P. J. White, Kelly M. Proffitt, L. David Mech, Shaney B. Evans, Julie A. Cunningham, Kenneth L. Hamlin
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Migration can enhance survival and recruitment of mammals by increasing access to higher-quality forage or reducing predation risk, or both. We used telemetry locations collected from 140 adult female elk during 2000– 2003 and 2007–2008 to identify factors influencing the migration of northern Yellowstone elk. Elk wintered in 2 semidistinct herd segments and migrated 10–140 km to at least 12 summer areas in Yellowstone National Park (YNP) and nearby areas of Montana. Spring migrations were delayed after winters with increased snow pack, with earlier migration in years with earlier vegetation green-up. Elk wintering at lower elevations outside YNP migrated an …
Proportion Of Calves And Adult Muskoxen, Ovibos Moschatus Killed By Gray Wolves, Canis Lupus, In July On Ellesmere Island, L. David Mech
Proportion Of Calves And Adult Muskoxen, Ovibos Moschatus Killed By Gray Wolves, Canis Lupus, In July On Ellesmere Island, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Generally Gray Wolves (Canis lupus L., 1758) tend to focus predation on young-of-the-year ungulates during summer, and I hypothesized that wolves preying on Muskoxen (Ovibos moschatus Zimmerman, 1780) in summer would follow that trend. Over 23 July periods observing wolves on Ellesmere Island, Nunavut, Canada, I found that packs of 2-12 adult wolves killed seven calves, one yearling, and five adult muskoxen at distances of 2.9 to 32 km from their current dens and pups. Given a possible bias against finding calves because of their fewer remains, these results do not necessarily refute the hypothesis, but they do …
What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech
What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The taxonomic identity of the historical and current wolf (Canis lupus L., 1758 or Canis lycaon Schreber, 1775 or their hybrids) population in Minnesota (MN) and the Great Lakes region has been, and continues to be, controversial. So too does its legal status under the U.S. Endangered Species Act. This review summarizes the morphological and genetic information about that population and concludes that historically the MN population consisted of a gray wolf (C. lupus) in the west and an eastern type (Canis lupus lycaon or C. lycaon) in the east with intergrades or hybrids between …

Niobrara National Scenic River Condition Assessment, Sunil Narumalani, Gary D. Willson, Christine K. Lockert, Paul B. T. Merani
United States National Park Service: Publications
Executive Summary
Niobrara National Scenic River spans a 122-km (76-mile) long reach of the Niobrara River in rural, north-central Nebraska. The scenic river encompasses 9,338 ha (23,074 acres) of land and water, all of which is in private ownership, except for about 320 ha (790 acres). Because the scenic river does not own land, it achieves management goals by coordinating and collaborating with federal, state, and local jurisdictions and private landowners.
The central Niobrara River Valley is often referred to as a “biological crossroads” with plant and animal species representative of northern boreal forest, eastern deciduous forest, rocky mountain coniferous …
Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff
Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son.With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this …
A Powerful New Planning Environment For Fuels Managers: The Interagency Fuels Treatment Decision Support System, Gail Wells
Joint Fire Science Program Digests
The Joint Fire Science Program, the National Wildfire Coordinating Group Fuels Management Committee, and Sonoma Technology, Inc. are unveiling the prototype of a new planning environment that will help fuels specialists negotiate the confusing array of planning tools. The new framework, dubbed the Interagency Fuels Treatment Decision Support System, or IFT-DSS, organizes fuels-planning software and data into a seamless user environment. IFT-DSS offers users access to powerful modeling software from within a well-designed, intuitive graphical user interface, and it provides a common platform for the further development of fuels-planning software tools. The name may not slide easily off the tongue—you …

Predatory Senescence In Ageing Wolves, Daniel R. Macnulty, Douglas W. Smith, John A. Vucetich, L. David Mech, Craig Packer
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
It is well established that ageing handicaps the ability of prey to escape predators, yet surprisingly little is known about how ageing affects the ability of predators to catch prey. Research into long-lived predators has assumed that adults have uniform impacts on prey regardless of age. Here we use longitudinal data from repeated observations of individually-known wolves (Canis lupus) hunting elk (Cervus elaphus) in Yellowstone National Park to demonstrate that adult predatory performance declines with age and that an increasing ratio of senescent individuals in the wolf population depresses the rate of prey offtake. Because this ratio fluctuates independently of …

Problems With The Claim Of Ecotype And Taxon Status Of The Wolf In The Great Lakes Region, Matthew A. Cronin, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Koblmuller et al. (2009) analyzed molecular genetic data of the wolf in the Great Lakes (GL) region of the USA and concluded that the animal was a unique ecotype of grey wolf and that genetic data supported the population as a discrete wolf taxon. However, some of the literature that the researchers used to support their position actually did not, and additional confusion arises from indefinite use of terminology. Herein, we discuss the problems with designation of a wolf population as a taxon or ecotype without proper definition and assessment of criteria.
Koblmuller et al. (2009) wrote ‘The GL …

Long Daily Movements Of Wolves, Canis Lupus, During Pup Rearing, L. David Mech, H. Dean Cluff
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Wolves, Canis lupus, on Ellesmere Island traveled a daily round-trip distance of 40.2 km from their den to a landfill during July 2008, plus an undetermined distance hunting after leaving the landfill. Although long travels by Wolves are well known, this appears to be the first documentation of long daily movements by Wolves rearing pups.

We tested whether Wolf (Canis lupus) visits to individual female White-tailed Deer (Odocoileus virginianus) summer ranges during 2003 and 2004 in northeastern Minnesota were in accord with optimal-foraging theory. Using GPS collars with 10- to 30-minute location attempts on four Wolves and five female deer, plus eleven VHF-collared female deer in the Wolves’ territory, provided new insights into the frequency of Wolf visits to summer ranges of female deer. Wolves made a mean 0.055 visits/day to summer ranges of deer three years and older, significantly more than their 0.032 mean visits/day to ranges of two-year-old deer, …

A Serological Survey Of Infectious Disease In Yellowstone National Park’S Canid Community, Emily S. Almberg, L. David Mech, Douglas W. Smith, Jennifer W. Sheldon, Robert L. Crabtree
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Background: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park (YNP) after a .70 year absence, and as part of recovery efforts, the population has been closely monitored. In 1999 and 2005, pup survival was significantly reduced, suggestive of disease outbreaks.
Methodology/Principal Findings: We analyzed sympatric wolf, coyote (Canis latrans), and red fox (Vulpes vulpes) serologic data from YNP, spanning 1991–2007, to identify long-term patterns of pathogen exposure, identify associated risk factors, and examine evidence for disease-induced mortality among wolves for which there were survival data. We found high, constant exposure to canine …

Guidelines For Re-Establishing Grey Partridges Through Releasing, Francis Buner, N. J. Aebischer
Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
In the UK, numbers of grey partridges have declined by over 75% during the last 20 years, and in many parts of the country the species has become locally extinct. Concerns over the magnitude of the decline led the UK Government to place the species on the short list of the UK Biodiversity Action Plan (BAP) for which the Game & Wildlife Conservation Trust was appointed lead partner in 1996. The Grey Partridge Species Action Plan’s targets are to restore numbers from 65,000 pairs in 2005 to 90,000 pairs nationally by 2010, and to expand its 1990 range. Over the …

The Fall 2008 Unl Bike Survey: Examining The Status Of Bicycle Transportation At The University Of Nebraska-Lincoln, Brent Schmoker
Department of Environmental Studies: Undergraduate Student Theses
This study evaluates the state of bicycle use by University of Nebraska-Lincoln (UNL) students during the fall semester of 2008. An online survey was administered to a random sample of graduate and undergraduate students to determine the factors that encourage and inhibit students from using bikes for transportation to campus. The results suggest that a significant portion of the student population uses bikes for transportation to campus but several factors combine to keep the overall number of bicycle commuters low. The paper concludes with suggestions for increasing bike commuting to UNL and predictions about the future of transportation in the …

Spatial And Temporal Differences In Giant Kidney Worm, Dictophyma Renale, Prevalence In Minnesota Mink, Mustela Vison, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Examination of 110 Mink (Mustela vison) carcasses from 1998 through 2007 indicated that the giant kidney worm, Dioctophyma renale, occurred in Pine and Kanabec Counties of eastern Minnesota with annual prevalences of 0-92%. Worm prevalence increased from 20% in 1999 to 92% in 2001 and decreased to 6% in 2005. During 2000 to 2007, no worms were found in Mink from Anoka and Chisago Counties (n = 54), and in 2000, none in 107 Mink from LeSeur, Freeborn, Redwood, Brown and Watonwan Counties. Changes in kidney worm prevalence were positively related to trapping success, considered an index …

Based on 168 records of both verbal descriptors of White-tailed Deer (Odocoileus virginianus) femur-marrow fat and percentage of fat measured later, “gelatinous” served well to distinguish fat < 46% from higher percentages. “Waxy” distinguished fat > 56%.
