Raptors And Racing Pigeons: An Analysis Of Avian Predation On Dome Pigeons, James B. Armstrong

Eastern Wildlife Damage Control Conference: 5th (1991)

Relationships among pigeons, raptors, and man are well documented. However, there has been little effort to study conflict between pigeon fanciers and raptors that prey upon racing pigeons. A questionnaire concerning the characteristics raptor predation on pigeons was distributed to members of the American Racing Pigeon Union (ARPU). Three hundred and sixty seven responses were received from ARPU members in 39 states. Cooper's hawks were the most often implicated raptor. Lots located at the edge of wooded areas experienced the most attacks (n =182). Most fanciers (n =154) indicated that raptor attacks were distributed throughout the day.

Gas Chromatographic Method For Determination Of 28 Volatile Organic Compounds Emitted From A Sewerage Plant, Yeming Sun

Theses

In this study, 28 volatile organic compounds (VOCs) emitted from the Linden Roselle Sewerage Authority Plant (LRSA) were monitered. The determination by gas chromatography (GC) is presented. This work emphasizes the collection of whole air samples, using a canister-based sampling system with cryogenic concentration. An appropriate temperature program was selected to obtain the best sample separation. The procedure for the identification of 28 standard gas mixture was achieved by comparing the chromatograms of sample with those of the specific groups of target compounds, as well as by comparing the sample with the results from GC Mass spectrometeric analysis. Because of …

An Analysis Of East Pond And The Serpentine Watersheds In Relation To Water Quality, Problems In Environmental Science Course (Biology 493), Colby College, Colby College

Colby College Watershed Study: East and North Ponds (2011, 1999, 1996, 1991)

The Belgrade Lakes in central Maine are important local ecological and recreational resources. The belgrade chain includes the following lakes: East Pond, North Pond, Great Pond, Long Pond, Salmon Lake and Messalonskee Lake. These lakes are all interconnected within the system driving into the Kennebec River through the Messalonskee Stream (Garrity and Putnam, 1971). East Pond is the first lake in the lake chain and it plays a pivotal role in influencing subsequent lakes. Therefore, the water quality of this lake is important not only to East Pond residents but to the residents of the entire lakes region.

Mariculture Management For Pohnpei State, Federated States Of Micronesia, Kevin Brooks Foster

Marine Affairs Theses and Major Papers

The Marine Resources Division of Pohnpei State, Federated States of Micronesia is currently engaged in development activities that include the establishment of family scale mariculture projects for community members of remote villages and outer islands. The goal of this undertaking is to supplement subsistence and income generation ventures for community members through the wise use and exploitation of the marine environment. These aims may be jeopardized unless a management plan is devised that reflects the customary marine resource practices as embraced by islanders from each community. The intent of this thesis projects is to devise a mariculture management model that …

Prospects For Fisheries Development In West Africa, Steven K. Ireland

Marine Affairs Theses and Major Papers

The production of food is a primary concern for the countries of Africa. Marine fisheries can contribute toward alleviating undernutrition and provide employment opportunities in developing countries. In West Africa there are substantial marine fisheries resources but there is a need for development and improved management of these resources. Fisheries development efforts have thus far achieved limited success in the region. However, there is considerable potential for increasing the contribution of fisheries to economic development if the problems of fisheries development can be overcome.

The Siia: A Mechanism For Addressing Pollution Problems Plaguing New Jersey's Coastal Zone, Laurie J. Sands

Marine Affairs Theses and Major Papers

New Jersey has been plagued in recent years by beach closures resulting from elevated bacteria levels after rainfall events. The Sewage Infrastructure Improvement Act (SIIA) was adopted to correct these problems by addressing both point and nonpoint sources of pollution found in discharges of stormwater. However, there are problems with the SIIA such as overly burdensome requirements, limited resources and lack of future funding and direction. This research identifies these problems and examines existing State and federal legislation to find the necessary components to correct these concerns. The results show that by pursuing a legislative amendment to the SIIA, redistributing …

Malaysia And The Law Of The Sea, Mohd Fadzil Shuhaimi

Marine Affairs Theses and Major Papers

The new legal regime of the oceans has brought many changes in the Malacca Strait. The most recent one in the enactment of the Malaysian Exclusive Economic Zone Act 1984 as corollary to its proclamation on the Exclusive Economic Zone in 1980. A year later, the Fisheries Act 1985 was enacted by Malaysia as a result of increasing needs to address new issues in fisheries protection and management in the Malaysian fisheries waters. The conclusion of the 1982 United Nations Convention on the Law of the Sea, among other things, has improvised the concept of transit passage in the straits …

How Windbreaks Work, James R. Brandle, Sherman Finch

School of Natural Resources: Faculty Publications

Windbreaks are barriers used to reduce and redirect wind. They usually consist of trees and shrubs, but may also be perennial or annual crops and grasses, fences, or other materials. The reduction in wind speed behind a windbreak modifies the environmental conditions or microclimate in the sheltered zone.

As wind blows against a windbreak, air pressure builds up on the windward side (the side towards the wind), and large quantities of air move up and over the top or around the ends of the windbreak. Windbreak structure – height, density, number of rows, species, composition, length, orientation, and continuity – …

Windbreak Establishment, Patricia Boehner, James R. Brandle, Sherman Finch

School of Natural Resources: Faculty Publications

A successful windbreak planting depends on proper establishment and care during the first few years after planting. Time spent in site preparation, weed control, and replanting is repaid many times during the lifetime of the windbreak. Take no shortcuts in the planning and establishment of your windbreak.

Windbreaks are investments in the future value of your property. Each windbreak system is unique and your windbreak should be designed for your site and objectives. Your local conservation office can provide help in designing and installing your windbreak. These organizations can also help with recommendations on where to buy planting stock, and …

Windbreaks And Wildlife, Ron J. Johnson, Mary M. Beck, James R. Brandle

School of Natural Resources: Faculty Publications

Windbreaks can support wildlife that add beauty and pleasure to our lives. They also sustain birds that eat insect pests, improve hunting opportunities, and provide a focal point for family outdoor activities. The world around us would be less appealing without the stimulation - the color, sounds, tracks, and mystery - of wild creatures; windbreaks help wildlife and in some areas are essential to survival of the wildlife we enjoy. You can add wildlife benefits to windbreak plantings whether your main goal is to shelter crops, livestock, + roads, or a home or farmstead.

This publication provides an overview of …

Windbreaks In Sustainable Agricultural Systems, Vernon C. Quam, John Gardner, James R. Brandle, Teresa K. Boes

School of Natural Resources: Faculty Publications

Sustainable agriculture is a system of whole-farm resource use balanced with whole-farm productivity. The overall level of productivity achieved is dependent upon the ability to coordinate and manage simultaneously the soil, water, plant, and animal resources within climatic and economic limits. Both the kind and amount of plants and animals supported by the system are important and play significant roles, both individually and collectively in maintaining a healthy farm environment. In the future, integrated systems will help reduce human impact on resources while providing sufficient supplies of high quality food and fiber.

Windbreaks provide protection for people, animals, buildings, crops, …

Wyoming Statewide Wilderness Study Report Wilderness Study Area Specific Recommendations, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

The recommendation for this WSA is to designate 17,150 acres of BLM land and 1,390 acres of State land as wilderness. This alternative is considered to be the environmentally preferable alternative as it would result in the least change in the natural environment over the long term. The entire 17,150 acres of federal land and 1,390 acres of state land within the WSA are recommended for wilderness designation and are shown on the Bobcat Draw Badlands WSA map. The state lands would be recommended for acquisition to enhance the manageability of the area as wilderness.

Modeling Age-Specific Mortality For Marine Mammal Populations, Jay Barlow, Peter Boveng

United States Department of Commerce: Staff Publications

A method is presented for estimating age-specific mortality based on minimal information: a model life table and an estimate of longevity. This approach uses expected patterns of mammalian survivorship to define a general model of age-specific mortality rates. One such model life table is based on data for northern fur seals (Callorhinus ursinus) using Siler’s (1979) 5-parameter competing risk model. Alternative model life tables are based on historical data for human females and on a published model for Old World monkeys. Survival rates for a marine mammal species are then calculated by scaling these models by the longevity …

This General Management Plan provides the National Park Service with direction for long-range management, development, and use of the Rainbow Bridge National Monument. The plan responds to new issues identified during the planning process when the draft plan was published in September of 1990. A main concern expressed during public review of the draft plan was diverse public expectations for visitor experience, crowding, and the high number of visitors accessing a limited area of Rainbow Bridge. In addition, the plan and environmental assessment address these diverse public expectations along with the issues of a visitor experience, protection of natural and …

13.2.8. Rescue And Rehabilitation Of Oiled Birds, Sallie Welte, Lynne Frink

Waterfowl Management Handbook

Oil contamination of waterfowl and seabirds has been documented as a significant cause of morbidity and mortality in birds for more than 50 years. Each year more than one million birds may die from oil contamination in North Atlantic waters alone; worldwide mortality is unknown.

Of special concern is that many of the seabirds commonly affected are not prolific breeders, and assessment of each species’ status is handicapped by the difficulty of accurately monitoring trends in marine bird populations.

Oiled bird rehabilitation is an intensive, crisis-oriented response, requiring an experienced management agency, specialized medical expertise, stockpiles of specially designed equipment, …

13.1.3. Life History Strategies And Habitat Needs Of The Northern Pintail, Leigh H. Fredrickson, Mickey E. Heitmeyer

Waterfowl Management Handbook

The northern pintail (hereafter pintail) is a common dabbling duck distributed throughout the Northern Hemisphere. Since 1955, the breeding population in North America has averaged 5,566,000, fluctuating between 10,124,000 (1956) and 2,471,000 (1989; Fig. 1). Pintail numbers are especially sensitive to habitat conditions that reflect the wet–dry cycle in the shortgrass prairie breeding areas of south-central Canada and the northern Great Plains of the United States. Populations of pintails also are affected by habitat conditions in key wintering areas, such as the Central Valley of California and Gulf Coast marshes. When wintering areas are fairly dry, birds have fewer resources …

Predation Risk And The Importance Of Cover For Juvenile Rainbow Trout In Lentic Systems, R. A. Tabor, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Juvenile rainbow trout Oncorhynchus mykiss stocked in midelevation reservoirs in Utah inhabit shallow nearshore areas and are vulnerable to predation from piscivorous fish and birds. We determined the use and importance of nearshore habitats by (1) measuring habitat selection by, prey availability to, and feeding of juvenile rainbow trout in two reservoirs with populations of predators, and (2) measuring survival and growth rates in the presence and absence of cover in a pond experiment where adult brown trout Salmo trutta were predators. In the reservoirs juvenile rainbow trout (60–120 mm standard length) were abundant in complex inshore habitats but avoided …

Survey Of The Damage Caused To Trees By Goats, Steve Gherardi, Dick Mills, Tim Johnson

Journal of the Department of Agriculture, Western Australia, Series 4

The damage that goats can cause to trees is one of the major problems associated with their farming in the agricultural areas of Australia. It is also considered one of the main hindrances to the development of the goat industry. The Department of Agriculture s Goat Industry Development Unit surveyed mohair and cashmere producers to determine the prevalence of tree damage and its extent and severity; why producers believed goats damaged trees; and how producers minimised or prevented this damage.

Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace

Journal of the Department of Agriculture, Western Australia, Series 4

Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.

Trees And Livestock : A Productive Co-Existence, Richard Moore

Journal of the Department of Agriculture, Western Australia, Series 4

Trees, as part of farming can help to combat land degradation problems and produce a good economic return from timber at the same time. For example, there is now clear evidence that planting trees can help combat salinity by lowering water-table levels. Trees can also substantially improve overall farm productivity by providing shelter for pastures and livestock. The challenge is to find practical and economical methods of integrating trees and farming. A combination of widely-spaced trees and livestock is one promising method. This article describes the benefits of this type of agroforestry to farmers, suitable locations and how to practice …
