Historical Changes In Mid-Water Stands Of Common Reed In The Winnebago Pool Lakes, Wisconsin, Anthony O. Gabriel, Leo R. Bodensteiner Dec 2002

Historical Changes In Mid-Water Stands Of Common Reed In The Winnebago Pool Lakes, Wisconsin, Anthony O. Gabriel, Leo R. Bodensteiner

All Faculty Scholarship for the College of the Sciences

Despite the tolerance of common reed grass to environmental extremes, mid-water stands in the Winnebago pool lakes of central Wisconsin appear to be diminishing. Formerly occupying shoreline locations, water level manipulations subsequent to dam construction beginning in the 1850's have isolated reed stands off shore. These stands have persisted but casual observations indicate that stand size has been declining. To address this perception we obtained an approximately decadal series of aerial photographs dating back to 1937 for four stands in Lake Poygan. Annual records were available for 1986–94. Using image analysis software, we determined shape and size metrics. Changes in …


Introduction To Special Issue On Radiation Effects, P. Andrew Karam Dec 2002

Introduction To Special Issue On Radiation Effects, P. Andrew Karam

The University of New Hampshire Law Review

[Excerpt] "How dangerous is radiation? How much radiation does it take to give us cancer? Are we wasting money on overly restrictive regulations, or are we not being sufficiently protective of our radiation workers and the public? How much clean-up is necessary on our Department of Energy facilities? What about Yucca Mountain and nuclear reactor plants – can they be made safe?

These are only a few of the questions that have been asked, and will continue to be asked, about radiation. Unfortunately, these all come down, in part or in whole, to the question “What is the shape of …


Historical Development Of The Linear Nonthreshold Dose-Response Model As Applied To Radiation, Ronald L. Kathren Dec 2002

Historical Development Of The Linear Nonthreshold Dose-Response Model As Applied To Radiation, Ronald L. Kathren

The University of New Hampshire Law Review

[Excerpt] "Despite the nearly universal adoption of the linear nonthreshold dose response model (LNT) as the primary basis for radiation protection standards for the past half century, the LNT remains highly controversial and a contentious topic of discussion among health physicists, radiation biologists, and other radiological scientists. Indeed, it has been pointed out that the LNT has assumed the status of a paradigm, synonymous with an ideal, standard, or paragon or perhaps to some, a sacred cow. Reduced to its very basics, the LNT postulates that every increment of ionizing radiation dose, however small, carries with it a commensurate increase …


An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, Brook Lauro, John Tanacredi Ph.D. Dec 2002

An Examination Of Predatory Pressures On Piping Plovers Nesting At Breezy Point, New York, Brook Lauro, John Tanacredi Ph.D.

Faculty Works: CERCOM

This study examines predatory threats to Piping Plovers (Charadrius melodus) nesting at Breezy Point, Gateway National Recreation Area, New York. Several methods used include: 1) an evaluation of reproductive success data with documentation of predation to eggs and chicks, 2) predator surveys, and 3) an artificial nest study. The range of breeding pairs nesting from 1988-1996 was 11-19, with an average of 15.8 (SE ± 0.79) pairs/season. The average number of eggs hatched and chicks fledged per year for pairs was 2.2 ± 0.23 and 0.8 ± 0.16 respectively. Reasons for egg losses often went undetected (68%) but …


Review Of "The Health Of Nations: Infectious Disease, Environmental Change, And Their Effects On National Security And Development," By Andrew T. Price-Smith, Andrew Mierins Dec 2002

Review Of "The Health Of Nations: Infectious Disease, Environmental Change, And Their Effects On National Security And Development," By Andrew T. Price-Smith, Andrew Mierins

The University of New Hampshire Law Review

[Excerpt] "Andrew T. Price-Smith, author of The Health of Nations: Infectious Disease, Environmental Change, and Their Effects on National Security and Development, provides a well documented and reasoned analysis of the need for world leaders, including the United States, to place the threat of infectious disease on the front burner of consideration when shaping both national and international policy. Professor Price-Smith has provided both empirical data and historical analysis to support the impassioned plea for this natural threat to be taken seriously. The book is geared toward the academic community and policy analysts; however, other professionals not involved in these …


The Debate On The Health Effects Attributable To Low Radiation Exposure, Abel J. Gonzalez Dec 2002

The Debate On The Health Effects Attributable To Low Radiation Exposure, Abel J. Gonzalez

The University of New Hampshire Law Review

[Excerpt] "Few scientific issues have aroused passions more than the dispute about the health effects attributable to low levels of exposure to ionizing radiation (or radiation in short) and the currently authoritative dose response hypothesis, termed “linear non-threshold,” or LNT. Finding out whether health effects are induced by low-level radiation exposures, and if so, what they are, has become a kind of contest rather than a serious scientific inquiry. Sometimes it seems that rationality, or a methodical examination of the unknown, has disappeared from this debate. While the confrontation of different hypotheses is typical in academic discussions – at least …


Effects Of The Shape Of The Radiation Dose-Response Curve On Public Acceptance Of Radiation And Nuclear Energy, Audeen W. Fentiman Dec 2002

Effects Of The Shape Of The Radiation Dose-Response Curve On Public Acceptance Of Radiation And Nuclear Energy, Audeen W. Fentiman

The University of New Hampshire Law Review

[Excerpt] “The public generally accepts the premise that exposure to radiation can have an undesirable effect. Furthermore, it believes that as the radiation dose increases, the magnitude of the effect will increase. On the other hand, while the background radiation dose varies from a few hundred millirem/year (a few millisieverts/yr) in some places to a few thousand millirem/yr (tens of millisieverts/yr) in others, researchers have been unable to find a correlation between the level of background radiation and incidence of cancer or other maladies attributable to radiation.

Because there is considerable controversy about the relationship between radiation dose and …


Representational Analyses Of Conservation Lands In Maine, Stephanie Orndorff Dec 2002

Representational Analyses Of Conservation Lands In Maine, Stephanie Orndorff

Electronic Theses and Dissertations

The three studies reported here (i.e., statewide, southern Maine, and state and federal wildlife areas) identify what areas should be conserved to represent the natural diversity of Maine. Geographic Information System (GIs) technology was used to conduct the analyses comparing the distribution of abiotic and biotic variables representing natural diversity on and off conservation lands. In the statewide analysis, 10 environmental variables were compared on and off conservation lands using ArcGrid with a cell resolution of 1.86 x 1.86 km. The areas found to contain variables that were underrepresented were. combined to identify and map regions with under-represented characteristics. The …


Ocean Zoning For The Gulf Of Maine: A Background Paper, Fara Courtney, Jack Wiggin Dec 2002

Ocean Zoning For The Gulf Of Maine: A Background Paper, Fara Courtney, Jack Wiggin

Urban Harbors Institute Publications

Coastal and ocean management is a constantly evolving practice. For at least two decades, coastal communities around the world have been experimenting with new ways to control a multitude of activities in their urban and rural harbors. The number and diversity of Marine Protected Areas are growing, with an increasing focus on protecting integrated biological communities, rather than individual species of concern. The United States and Canada are each developing new, comprehensive ocean polices, looking to better integrate management functions at all levels of government.

All of these initiatives – from local to national - reflect some common truths about …


Report To The Minister For Agriculture, Forestry And Fisheries By The Integrated Fisheries Management Review Committee, Department Of Fisheries Nov 2002

Report To The Minister For Agriculture, Forestry And Fisheries By The Integrated Fisheries Management Review Committee, Department Of Fisheries

Fisheries management papers

The Integrated Fisheries Management Review Committee was established to develop a strategy to integrate the management and sustainable use of fish resources. The Committee’s report proposes an alternative management framework and a set of guiding principles for allocating fish stocks to ensure optimal benefits are realised for the WA community. The report does not, and was not intended to, address specific allocation issues in particular fisheries – this will be a function of the framework and processes put in place following this review.


A Perspective On Two Decades Of Policies And Regulations Influencing The Protection And Restoration Of Submerged Aquatic Vegetation In Chesapeake Bay, Usa, R J. Orth, Ra Batiuk, Pw Bergstrom, Ken Moore Nov 2002

A Perspective On Two Decades Of Policies And Regulations Influencing The Protection And Restoration Of Submerged Aquatic Vegetation In Chesapeake Bay, Usa, R J. Orth, Ra Batiuk, Pw Bergstrom, Ken Moore

VIMS Articles

Seagrasses along with many other species of freshwater rooted submerged macrophytes in Chesapeake Bay (collectively called SAV) underwent serious declines in population abundances in the 1970s and have not as yet rebounded to previous levels. Cooperative efforts by scientists, politicians, federal and state resource managers, and the general public have developed policies and plans to protect, preserve and enhance SAV populations of Chesapeake Bay. These include the Chesapeake Bay Agreements (1983, 1987, 1992, 1993, 2000), an SAV Management Policy and Implementation Plan for Chesapeake Bay and Tidal Tributaries (1989 and 1990), Chesapeake Bay Blue Crab Fishery Management Plan (1997), as …

Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell Oct 2002

Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell

Agriculture reports

These pasture condition guides are relevant to about 192 000 square kilometres of the Pilbara region of Western Australia. The rangeland of the Pilbara can be separated into 12 very broad pasture types. The ‘pasture type’ is not strictly a botanical classification because, in determining such a class of pastoral lands, the perennial plant species that contribute to stock production have an over-riding importance. Even so, each pasture type represents a broad group of similar vegetation associations or ‘site types’ which will have similar management requirements for pastoralism. The aim of this publication is to provide pastoralists with descriptions and …

Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George Oct 2002

Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George

All other publications

Agriculture has been and will continue to be a major component of economic activity in several regions in Western Australia, and agricultural communities will remain an important part of the social fabric and landscape of the State. Promoting the sustainability of agriculture is likely to produce three main outcomes: vibrant rural communities; profitable agricultural systems; and conservation of the natural environment. This paper describes briefly the main challenges to the sustainability of agriculture and outlines some means of responding to the challenges: market-based approaches; agricultural and environmental research and development; accelerated adjustment; and global and national policy initiatives.


Identifying Sources Of Fecal Pollution In The Roanoke River, Roanoke County, Virginia, J. Brooks Crozier, Brian Clark, Holly Weber Oct 2002

Identifying Sources Of Fecal Pollution In The Roanoke River, Roanoke County, Virginia, J. Brooks Crozier, Brian Clark, Holly Weber

Virginia Journal of Science

Antibiotic Resistance Patterns (ARPs) of Enterococcus spp. were used as a phenotypic fingerprint to compare and categorize unknown-source isolates in an impaired segment of the Roanoke River, Roanoke County, Virginia. Antibiotic resistance analysis (ARA) of enterococci has been effectively used to differentiate among sources of fecal contamination in many geographic regions in the United States. Enterococcus spp. were used as a fecal indicator in a library consisting of 1,562 known-source isolates. Two-way analysis indicated that approximately 95% of the unknown-source isolates collected were of animal origin. A 3-way analysis indicated that 61% of the unknowns were of livestock origin while …

Understory Species Patterns And Diversity In Old-Growth And Managed Northern Hardwood Forests, Robert M. Scheller, David J. Mladenoff Oct 2002

Understory Species Patterns And Diversity In Old-Growth And Managed Northern Hardwood Forests, Robert M. Scheller, David J. Mladenoff

Environmental Science and Management Faculty Publications and Presentations

Forest management can significantly affect both the diversity and spatial patterning of understory vegetation. However, few studies have considered both diversity and spatial patterning at a stand scale. Our objective was to evaluate the effects of forest management on understory plant communities in northern hardwood forests and assess the processes governing differences in species composition, diversity, and spatial patterns. We sampled understory vegetation (all speciestall) and percentage of light transmission levels in three forest types in 12 mesic northern hardwood stands in northern Wisconsin and the Upper Peninsula of Michigan, USA: old-growth, undisturbed forests; even-aged forests resulting from clearcut logging …

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer Aug 2002

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer

School of Natural Resources: Dissertations, Theses, and Student Research

The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …


Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg Aug 2002

Reseeding Of Grazing Gastropods And Bivalves Into The Marine Environment In Western Australia, Jane Borg

Fisheries management papers

The Department of Fisheries does not want to embark on what is ‘new territory’ in Western Australia without a policy framework to define what is to happen, why it is to happen, and what will happen if the project does or does not succeed. This paper therefore attempts to do three things. 1. It sets in place accepted definitions of reseeding and stock enhancement within the general context of fisheries management in Western Australia. 2. It discusses the policy issues associated with reseeding grazing gastropods and bivalves into the natural environment. 3. It proposes a framework or process to be …

Comparison Of Water Quality, Zooplankton Density, And Cover In Razorback Sucker (Xyrauchen Texanus [Abbott]) Spawning Areas Of Lake Mead And Lake Mohave, Michael E. Golden, Paul B. Holden, Southern Nevada Water Authority Jul 2002

Comparison Of Water Quality, Zooplankton Density, And Cover In Razorback Sucker (Xyrauchen Texanus [Abbott]) Spawning Areas Of Lake Mead And Lake Mohave, Michael E. Golden, Paul B. Holden, Southern Nevada Water Authority

Publications (WR)

Las Vegas Bay and Echo Bay in Lake Mead have small, self-sustaining populations of razorback sucker (Xyrauchen texanus [Abbot]). Increased productivity and cover have been hypothesized as reasons for successful recruitment of razorback sucker in Lake Mead. Conversely, reproduction has been documented on Lake Mohave, another lower Colorado River reservoir, but no recruitment has been observed. In 2000, BIO-WEST, Inc. was contracted by the Southern Nevada Water Authority to design and implement a study to examine nutrient levels, zooplankton density, and cover in areas with and without razorback sucker recruitment success. We sampled Echo Bay, Las Vegas Bay, and …

Characterization Of The Dust/Smoke Aerosol That Settled East Of The World Trade Center (Wtc) In Lower Manhattan After The Collapse Of The Wtc 11 September 2001, Paul J. Lioy, Clifford P. Weisel, Et Al, Robert C. Hale

VIMS Articles

The explosion and collapse of the World Trade Center (WTC) was a catastrophic event that produced an aerosol plume impacting many workers, residents, and commuters during the first few days after 11 September 2001. Three bulk samples of the total settled dust and smoke were collected at weather-protected locations east of the WTC on 16 and 17 September 200 1; these samples are representative of the generated material that settled immediately after the explosion and fire and the concurrent collapse of the two structures. We analyzed each sample, not differentiated by particle Size, for inorganic and organic composition. In the …
