Integrated Pest Management Of Black Bear Reforestation Damage, Gary W. Witmer, Dale L. Nolte, William Stewart

United States Department of Agriculture Wildlife Services: Staff Publications

Black bear damage to commercial, coniferous trees on intensively managed public and private forest lands of the Pacific Northwest continues to be a problem for forest managers. Historically, methods such as relocation or spring hunts have been used in an effort to reduce bear density and damage. More recently, supplemental feeding has been used in an attempt to provide for the nutritional needs of bears during the damage period. Alternative silvicultural practices and repellents are being investigated for their ability to reduce the likelihood of bear damage. These and other methods need to be examined for their effectiveness, especially in …

Cormorant Research And Impacts To Southern Aquaculture, Scott Werner

United States Department of Agriculture Wildlife Services: Staff Publications

Several North American waterbird species were negatively affected by compromised environmental quality by the mid-twentieth century. Double-crested cormorant populations responded to increased environmental regulations in the United States in the early 1970s. The abundance of cormorants wintering in southern states (especially Alabama, Arkansas, Louisiana, and Mississippi) increased concurrently with a marked increase in catfish, crawfish, and bait fish production in these states since 1980, thus increasing regional concern regarding production losses to these industries. Cormorants wintering in Mississippi have increased nearly 225% since 1990. Food habit studies, bioenergetic predictions, and captive-bird foraging experiments indicate that individual cormorants consume approximately 0.5 …

Evaluation Of Hot Sauce® As A Repellent For Forest Mammals, Kimberly K. Wagner, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

Foraging by forest mammals can be significantly detrimental to reforestation efforts. Repellents may offer a nonlethal solution for some situations. Hot Sauce® animal repellent uses capsaicin, a trigeminal irritant that should be aversive to most mammals. We conducted a series of tests evaluating the impact of Hot Sauce on foraging by 5 species of forest mammals. In our first study, we examined its potential to reduce browsing by black-tailed deer (Odocoileus hemionus). Damage to Western redcedar seedlings (Thuja plicata) was initially reduced with application of a 6.2% Hot Sauce solution, but efficacy began to decline after …

Deer Population Management Through Hunting In A Suburban Nature Area In Eastern Nebraska, Kurt C. Vercauteren, Scott E. Hygnstrom

United States Department of Agriculture Wildlife Services: Staff Publications

The Fontenelle Forest Nature Area (FF) maintained a hands-off management policy for 30 years until it was recognized that white-tailed deer (Odocoileus virginianus) populations had grown to such levels that they were severely degrading native plant communities. In 1995, members of a community task force decided to sponsor annual nine-day hunting seasons on FF after learning that densities exceeded 28 deer/km². Archers harvested 85 antlerless deer in the FF upland areas adjacent to residential Bellevue, Nebraska during 1996 to 1998. Muzzleloader hunters removed 53 antlerless deer from the FF lowland areas. Archery and muzzleloader hunters harvested …

Urban-Suburban Prairie Dog Management: Opportunities And Challenges, Gary W. Witmer, Kurt C. Vercauteren, Karen Manci, Donna Dees

United States Department of Agriculture Wildlife Services: Staff Publications

The historic range of the black-tailed prairie dog has undergone dramatic declines in the last century, prompting concern about the species' long-term viability. While considered a pest by many, others believe that the species is a "keystone" element of prairie ecosystems. Urban-suburban land managers are challenged with preserving colonies of prairie dogs on public lands while dealing with many conflicting interests, social costs, and risks. We review the management plans that municipalities have designed to reduce conflicts by using public input, zoned management, and a variety of management techniques. Areas of difficulty and research needs are also discussed.

Bulletin 4446 - Ord Land And Water Management Plan 2000, Agriculture Western Australia, Community Of Kununurra

Fisheries Research Report No. 118 - A Study Into Western Australia's Open Access And Wetline Fisheries, F Crowe, W Lehre, R C J Lenanton

Fisheries Research Reports

Western Australia's wetline fishery potentially includes every licensed fishing boat in the State and encompasses a number of inter-relationships between various boats and commercial fisheries. This study covers the 'wetline' or open access fishery, which encompasses those activities associated with the unrestricted Western Australian fishing boat licence (FBL). The activities associated with this fishery involve any commercial fishing which is not covered by fisheries legislation.

A separate section entitled 'So you want to go wetlining?' is provided at page 101 as an easy reference guide to industry and others interested in wetline fishing. It is recommended that it be read …

Investigating Ground And Surface Water In The Republican River Basin Of Nebraska Using Water Chemistry And Environmental Isotopes, Jennifer J. Schellpeper

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

Recent legal battles concerning water use initiated an investigation of the stream/aquifer relationships in the Republican River Basin located in southwest Nebraska. Ground and surface water was analyzed for tritium, deuterium, ¹⁸O, and major ions. Temperature, pH, conductivity and alkalinity were determined on-site. Samples were collected during 1997 and 1998 from irrigation wells throughout the entire basin. Localized interactions between groundwater and surface water were examined during twenty-four hour pump tests performed on the irrigation wells screened in the alluvium along the river valley and its tributaries. These data show there are differences between the ground and surface waters …

The Sustainable, The Expendable, And The Obsolete, Michael D. Lieber

Pacific Studies

This is a preliminary exploration of the concept of sustainability and its potential usefulness to anthropologists. “Sustainable” is distinguished from “stable” and “viable” in terms of its implications of directionality of time, pointing both backward and forward. Given the time implications, the contexts of “sustainable Xs” (technology, activity, development, etc.) are crucial to explaining what happened to X in the past and prognosticating its future. The argument is illustrated by analyzing data on obsolete fishing practices on Kapingamarangi Atoll (Federated States of Micronesia), focusing on the contexts of change in political /religious organization in the twentieth century. Changing access to …

Development, Sustainability, And The Deforestation Of Samoa, Paul Shankman

Pacific Studies

The forests of Samoa (formerly Western Samoa) are rapidly disappearing. This article reviews the history of Samoan deforestation, particularly during the last four decades, in the context of ideas about development and sustainability. It also examines the role of village agriculturalists in the process of deforestation. Recent economic, technological, and organizational changes have increased village agricultural expansion and, consequently, deforestation.

The Effect Of Divalent Cations On The Prophenoloxidase Enzyme Cascade Activity In The Freshwater Crayfish Cambarus Latimanus, Hans Skailand Eikaas

Theses and Dissertations

The effect of divalent cations such as cadmium, calcium, copper, lead and magnesium upon the prophenoloxidase system (proPO) was studied in hemocytes of the crayfish Cambarus latimanus. It was demonstrated that cadmium, calcium, copper and lead increased proPO activity significantly, whereas magnesium had no statistically significant effect on the system. Also, the molecular weight of the proPO enzyme was estimated using SDS-PAGE and found to be approximately 76 kDa.

Legislating A Sustainable Land Ethic For New Zealand, Michèle D. Dominy

Pacific Studies

This article explores competing discourses of sustainability in New Zealand’s South Island. As active resource managers, high-country pastoralists’ conception of “country” contests predominant reductive and binary models of production/ conservation and economic resource/visual resource and suggests a more complicated dynamic between scientific and cultural paradigms of sustainability than has been acknowledged. This dynamic is captured in the internationally driven top-down concept of equitable sustainable land management with a dual commitment to both cultural and ecological diversity as defined locally, formulated as part of the United Nations Rio Declaration of 1992, agenda 21, chapter 13. I examine an emergent high-country “land …

Artisanal Coral Reef Fisheries And Sustainable Development: The Arno Atoll Fisheries Association, Jim Hess

Pacific Studies

The concept of sustainable development is inexact, requiring additional specification in application. How the subject of analysis is bounded will have consequences for understanding what is being sustained as well as for determining whether something is sustained. Here I examine a fisheries development project in the Marshall Islands. Shifting boundaries, I create three accounts of the project. In the first account, which focuses on resources and monetary cost and benefits, the project is clearly unsustainable. In the second account, focusing on international relations, the project sustains the relations of power and dependency. In the third account, I suggest that evaluation …

Is Tonga's Mirab Economy Sustainable? A View From The Village And A View Without It, Mike Evans

Pacific Studies

The development implications of the now-classic MIRAB economic pattern for South Pacific microstates (with economies dominated by overseas remittances and foreign aid) have attracted considerable attention. Some scholars argue the MIRAB pattern is well entrenched and can be sustained with a minimum of undesirable social and economic outcomes. Others decry the acceptance of the dependency of South Pacific nations and argue for renewed effort toward the development of self-sustaining economies. I argue that the debate must directly address the underlying social relations that facilitate and shape migration and remittances. In Tonga, the movement of people from rural areas has wide-ranging …

Production Of The Subtropical Seagrass, Halodule Wrightii Aschers., In Lower Laguna Madre, Texas, Joseph L. Kowalski

Theses and Dissertations - UTB/UTPA

The autecology of shoal grass, Halodule wrightii Aschers., was studied at 1.2 m depth from June 1995 to February 1997 in Lower Laguna Madre (LLM), Texas. Halodule wrightii in LLM received about 47% surface irradiance, but otherwise displayed lower growth rates and biomass in nutrient-poor rhizosphere and water-column environments compared to H. wrightii populations in other Texas estuaries. High tissue N content and low C:N ratios belied low growth dynamics. Halodule wrightii in LLM is probably nutrient limited. A high nutrient demand by H. wrightii in a nutrient-poor environment may explain, in part, its gradual displacement by Thalassia testudinum and …

Effects Of Watershed Land Use On The Benthic Macroinvertebrate Assemblages In Ridge And Valley Streams In Chattanooga, Tennessee, Paul Leiper Freeman

Masters Theses and Doctoral Dissertations

A total of 20 sites in five Ridge and Valley streams located in Chattanooga, Tennessee were sampled May 8, 1998 to June 18, 1998 using quantitative and qualitative macroinvertebrate sampling techniques. All streams sampled were part of the Tennessee River drainage system and eventually contribute to Nickajack Reservoir. The 20 sites were second to fourth order streams with drainage areas of 3.8 to 46.9 (km2) and elevations of 195 to 232 (m). Sites with different percentages of agricultural, urbanized and forested land-use were selected to best evaluate the resulting impacts of urbanization and other anthropogenic activities on the invertebrate community …

Wildlife-Caused Losses For Producers Of Channel Catfish Ictalurus Punctatus In 1996, Alice P. Wywialowski

United States Department of Agriculture Wildlife Services: Staff Publications

The National Agricultural Statistics Service surveyed by telephone and mail in January and February 1997 all known producers of channel catfish Ictalurus punctatus to acquire current information about wildlife-caused losses in calendar year 1996. Many producers tried to prevent wildlife-caused losses of their catfish by shooting (57%), vehicle patrol (55%), or frightening (36%), at an estimated cost of >$5 million. Yet, 69% of catfish produces cited some wildlife-caused losses. Birds were most frequently cited as a cause of losses, and double-crested cormorants Phalacrocorax auritus was the species cited most frequently (53%). The next most frequently cited bids were herons Ardea …

Earth In Four Dimensions: Development Of The Ideas Of Geologic Time And History, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Changes in ideas and in technology can come about as slow incremental modifications, as well as by major paradigm shifts. In the case of the development of the ideas of geologic history and time, I will try to present these changes broadly and then look at how some of these have affected interpretation of Nebraska geology. Changes of view on three fronts were important in the development of geologic history and time concepts. First is the question of the nature of time. Is time cyclic or is it linear? The Greco-Oriental cultures had a world view based on cosmic cycles, …
