The Savannah River Site: Site Description, Land Use And Management History, David L. White, Karen F. Gaines
The Savannah River Site: Site Description, Land Use And Management History, David L. White, Karen F. Gaines
Publications
The 78,000-ha Savannah River Site, which is located in the upper Coastal Plain of South Carolina along the Savannah River, was established as a nuclear production facility in 1951 by the Atomic Energy Commission. The site’s physical and vegetative characteristics, land use history, and the impacts of management and operations are described. Aboriginal and early European settlement was primarily along streams, where much of the farming and timber cutting have occurred. Woodland grazing occurred in the uplands and lowlands. Land use intensity increased after the Civil War and peaked in the 1920s. Impacts from production of cotton and corn, naval …
Microbial Biofilms: From Ecology To Molecular Genetics, Mary Ellen Davey, George A. O'Toole
Microbial Biofilms: From Ecology To Molecular Genetics, Mary Ellen Davey, George A. O'Toole
Dartmouth Scholarship
Biofilms are complex communities of microorganisms attached to surfaces or associated with interfaces. Despite the focus of modern microbiology research on pure culture, planktonic (free-swimming) bacteria, it is now widely recognized that most bacteria found in natural, clinical, and industrial settings persist in association with surfaces. Furthermore, these microbial communities are often composed of multiple species that interact with each other and their environment. The determination of biofilm architecture, particularly the spatial arrangement of microcolonies (clusters of cells) relative to one another, has profound implications for the function of these complex communities. Numerous new experimental approaches and methodologies have been …

Palaeoecological Implications Of Archaeological Seal Bone Assemblages: Case Studies From Labrador And Baffin Island, James M. Woollett, Anne S. Henshaw, Cameron P. Wake
Earth Sciences
. In recent years, increasing scientific attention has been paid to sea mammals as biological indicators of Arctic environmental change. The usefulness of animals such as ringed seal (Phoca hispida), harp seal (Phoca groenlandica), bearded seal (Erignathus barbatus), and harbour seal (Phoca vitulina) as indicator species is due to the close relationship of their range, reproductive cycles, and life histories to sea ice. The behaviour and distribution of these species correlate with ice conditions in the areas where the animals are encountered. The proportions of seal species represented in archaeological deposits may therefore reflect, at least in part, environmental conditions …

University of Nebraska State Museum: Mammalogy Papers
On 11 June 2000, Dr. Elmer C. Birney unexpectedly passed away from cardiac arrest suffered while outside caring for his cattle at his home in Blaine, Minnesota. One of his former students, Robert Timm, probably best expressed the immediate reaction of his family and many friends: ‘‘He was too young and in too good of health to be gone so soon.’’ At the time of his death, Elmer was Professor in the Department of Ecology, Evolution and Behavior, the Curator of Mammals at the Bell Museum of Natural History, and Director of Graduate Studies of the program in Ecology, Evolution …
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
Wildlife Damage Management Conference Proceedings
Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …
Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage In The Suburbs: Conflicts In A Human-Wildlife Landscape, Rebecca Field
Wildlife Damage Management Conference Proceedings
The sprawling communities surrounding cities pose a paradox for wildlife. Suburban habitat, with parks, greenways, and planned open spaces, provide attractive habitat with abundant resources for some wildlife species. Yet the landscape is dominated by human activities and disturbances. Species with little tolerance for human disturbance and habitat changes have difficulty maintaining their populations in suburban environments. Yet more adaptable species flourish in suburban areas where there are less predators, increased food resources, and abundant habitat for cover and raising young. The resulting overabundant wildlife populations pose increasing problems for biologists, wildlife damage practitioners, and the public. Management of urban …
Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management
Management Guidelines For Sage Grouse And Sagebrush Ecosystems In Nevada, Bureau Of Land Management
All U.S. Government Documents (Utah Regional Depository)
These management guidelines and supportive background information promote the conservation of sage grouse (Centrocercus urophasianus) and their sagebrush (Artemisia spp) habitats on Nevada public lands administered by Bureau of Land Management (BLM). The guidelines are intended to provide interim guidance to field managers, without restricting options currently being explored for regional, state, and local sage grouse/sagebrush conservation planning. The guidelines are a Nevada BLM, habitat-specific, adaptation of the recently updated, and soon to be finalized, Western Association of Wildlife Agencies (WAFWA) Draft Guidelines. The Nevada BLM guidelines apply the most current sage grouse science to BLM activities, within the context …
Occurrence And Distribution Of Diverse Populations Of Magnetic Protists In A Chemically Stratified Coastal Salt Pond, Dennis A. Bazylinski, David R. Schlezinger, Brian H. Howes, Richard B. Frankel, Slava S. Epstein
Occurrence And Distribution Of Diverse Populations Of Magnetic Protists In A Chemically Stratified Coastal Salt Pond, Dennis A. Bazylinski, David R. Schlezinger, Brian H. Howes, Richard B. Frankel, Slava S. Epstein
Physics
Chemical stratification occurs in the water columns and sediments of many aquatic habitats resulting in vertical chemical and redox gradients. Various types of microorganisms are often associated with specific depths and chemical parameters in these situations. For example, magnetite-producing magnetotactic bacteria are known to form horizontal “plates” of cells at the oxic/anoxic transition zone (OATZ) of such environments. Here, we report the presence of populations of diverse magnetic protists in a seasonally chemically stratified, coastal salt pond. The protistan types included several biflagellates, a dinoflagellate, and a ciliate that were each associated with specific depths and thus, specific chemical, microbiological …
The Use Of Border Collies To Disperse Birds At Southwest Florida International Airport, Bobby D. O'Rick
The Use Of Border Collies To Disperse Birds At Southwest Florida International Airport, Bobby D. O'Rick
2000 Bird Strike Committee-USA/Canada, 2nd Annual Meeting, Minneapolis, MN
Similar to many airports throughout the United States and Canada, Southwest Florida International Airport (RSW) has a number of development features attractive to wildlife. Such features include stormwater detention ponds, large expanses of open fields, natural wetland marshes, and mature trees. In order to maintain safe operations and minimize the potential for wildlife-aircraft collisions, RSW has expanded the existing wildlife harassment program to include the use of a border collie. An Ecological Study completed by the United States Department of Agriculture (USDA) in 1997 indicated regular use of the airfield throughout the year by wading birds, waterfowl, and blackbirds. Although …

Cancer Surveillance Series: Non-Hodgkin’S Lymphoma Incidence By Histologic Subtype In The United States From 1978 Through 1995, Frank D. Groves, Martha S. Linet, Lois B. Travis, Susan S. Devesa
Public Health Resources
Background: Clinical investigations have shown prognostic heterogeneity within the non-Hodgkin’s lymphomas (NHLs) according to histology, but few descriptive studies have considered NHLs by subgroup. Our purpose is to assess the demographic patterns and any notable increases in population- based rates of different histologic subgroups of NHL.
Methods: Using data collected by the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute, we calculated incidence rates for the major clinicopathologic categories of NHL by age, race, sex, geographic area, and time period.
Results: Among the 60 057 NHL cases diagnosed during the period from 1978 through 1995, total incidence …
Nutrient Absorption And Utilization By Wing And Flight Muscle Morphs Of The Cricket Gryllus Firmus: Implications For The Trade-Off Between Flight Capability And Early Reproduction, Anthony J. Zera, Tammy Brink
Nutrient Absorption And Utilization By Wing And Flight Muscle Morphs Of The Cricket Gryllus Firmus: Implications For The Trade-Off Between Flight Capability And Early Reproduction, Anthony J. Zera, Tammy Brink
Anthony Zera Publications
Absorption efficiency (AD, approximate digestibility, assimilation efficiency) of various macronutrients and conversion of absorbed nutrients to biomass (ECD) were compared among the two types of flightless morph and the flight-capable morph of the cricket, Gryllus firmus. No biologically significant phenotypic or genetic difference in AD for carbohydrate, protein or lipid was observed among morphs fed either a high-nutrient (100%) or a low-nutrient (25%) diet. Thus, previously-documented differences among adult morphs in carbohydrate and lipid content must be caused by processes other than variation in nutrient absorption by morphs during adulthood. Relative absorption efficiency of total dry mass of food …

The Impact Of Lianas On Tree Regeneration In Tropical Forest Canopy Gaps: Evidence For An Alternative Pathway Of Gap‐Phase Regeneration, Stefan A. Schnitzer, James W. Dalling, Walter P. Carson
The Impact Of Lianas On Tree Regeneration In Tropical Forest Canopy Gaps: Evidence For An Alternative Pathway Of Gap‐Phase Regeneration, Stefan A. Schnitzer, James W. Dalling, Walter P. Carson
Biological Sciences Faculty Research and Publications
1 Regeneration in forest canopy gaps is thought to lead invariably to the rapid recruitment and growth of trees and the redevelopment of the canopy. Our observations, however, suggest that an alternate successional pathway is also likely, whereby gap‐phase regeneration is dominated by lianas and stalled in a low‐canopy state for many years. We investigated gap‐phase regeneration in an old‐growth tropical forest on Barro Colorado Island (BCI) in Panama to test the following two hypotheses: (i) many gaps follow a pathway in which they remain at a low canopy height and are dominated by lianas and (ii) the paucity of …

Chronic Arsenic Exposure And Risk Of Infant Mortality In Two Areas Of Chile, Claudia Hopenhayn-Rich, Steven R. Browning, Irva Hertz-Picciotto, Catterina Ferreccio, Cecilia Peralta, Herman Gibb
Preventive Medicine and Environmental Health Faculty Publications
Chronic arsenic exposure has been associated with a range of neurologic, vascular, dermatologic, and carcinogenic effects. However, limited research has been directed at the association of arsenic exposure and human reproductive health outcomes. The principal aim of this study was to investigate the trends in infant mortality between two geographic locations in Chile: Antofagasta, which has a well-documented history of arsenic exposure from naturally contaminated water, and Valparaíso, a comparable low-exposure city. The arsenic concentration in Antofagasta's public drinking water supply rose substantially in 1958 with the introduction of a new water source, and remained elevated until 1970. We used …

The Impacts Of A Nonindigenous Marine Predator In A California Bay, Edwin D. Grosholz, Gregory M. Ruiz, Cheryl A. Dean, Kim A. Shirley, John L. Maron, Peter G. Connors
Biological Sciences Faculty Publications
Coastal marine ecosystems worldwide are being altered rapidly by the invasion of nonindigenous species. Unlike terrestrial and freshwater systems, the impacts of an invading species have never been quantified on multiple trophic levels for a marine food web. We measured the impact of the nonindigenous green crab, Carcinus maenas, on a coastal marine food web in central California and found that this predator exerted strong “top-down” control, significantly reducing the abundances of several of the 20 invertebrate species monitored over a 9-yr period. Densities of native clams, Nutricola tantilla and Nutricola confusa, and native shore crabs, Hemigrapsus oregonensis, showed 5-fold …

Seasonal Comparison Of Remotely Sensed Relative Forest Ecosystem Temperature Zones With Topography And Forest Biomass In The Clear Springs Wilderness Area Of The Shawnee National Forest, Daniel Unger
Faculty Presentations
The use of thermal infrared data to delineate seasonal relative forest ecosystem temperature zones as a tool for forest ecological studies was analyzed. Analysis involved: (1) delineating relative seasonal forest ecosystem temperature zones within the Clear Springs Wilderness Area of the Shawnee National Forest using Landsat Thematic Mapper thermal infrared data; and, (2) quantifying the effect of topography and forest biomass on relative forest ecosystem temperature zones within seasons. Results indicate that slope was statistically uncorrelated with relative temperature zones within any season, aspect was statistically correlated with relative temperature zones during fall and winter, and forest biomass was statistically …

California produces 90% of all wine within the U.S. and dominates the $33 billion/year domestic retail wine industry. Since the 1950s, wine grape growers in California have seen dramatic increases in premium wine quality, grape yield, and crop value. Advances in viticultural practices (irrigation, nutrition, pest/disease control, trellising etc.) and experience in wine making have certainly contributed to the success (Jackson and Lombard 1993). In spite of such advances, wine growers generally believe climate plays a significant role in determining the quantity and quality of a given vintage.
Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel
Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel
Environmental Science and Management Faculty Publications and Presentations
We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (Ci) and of the number of islands without line-of sight connection (Bi). In partial regression analyses, controlling for nearest island area (A2) …

Estimating Animal Abundance Using Noninvasive Dna Sampling: Promise And Pitfalls, L. Scott Mills, J. J. Ciatta, K. P. Lair, M. K. Schwartz, D. A. Tallmon
Wildlife Biology Faculty Publications
Advances in molecular biology offer promise to the study of demographic characteristics of rare or hard-re-capture species, because individuals can now be identified through noninvasive sampling such as fecal collection or hair snags. However, individual genotyping using such methods currently leads to a novel problem that we call a "shadow effect," because some animals not captured previously are believed to be recaptures due to their DNA profile being an indistinguishable shadow of previously captured animals. We evaluate the impact of the shadow effect on the two methods most commonly used in applied population ecology to estimate the size of closed …
