Degree Of Sedentarization Affects Risks And Conflicts For The Waso Boran In Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Mark N. Mutinda, Abdilla A. Aboud Dec 2005

Degree Of Sedentarization Affects Risks And Conflicts For The Waso Boran In Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Mark N. Mutinda, Abdilla A. Aboud

Environment and Society Faculty Publications

The Waso Borana have lived for over a century in northern Kenya. In the last few decades, however, their ability to maintain their traditions has been severely challenged. Here we report survey results from 540 households in Isiolo District, stratified among three groups differing in terms of lifestyle: sedentary, semi-sedentary, and mobile. In some cases these groups vary with respect to important perceived risks, causes of natural-resource related conflict, and possible solutions to conflict. For example, sedentary respondents often noted concerns over land tenure problems, human diseases, and political incitement. Mobile respondents, in contrast, often noted primary concerns over drought, …


Agro-Pastoralists’ Wrath For The Prosopis Tree: The Case Of The Il Chamus Of Baringo District, Kenya, D. Layne Coppock, Abdillahi A. Aboud, Phillip K. Kisoyan Dec 2005

Agro-Pastoralists’ Wrath For The Prosopis Tree: The Case Of The Il Chamus Of Baringo District, Kenya, D. Layne Coppock, Abdillahi A. Aboud, Phillip K. Kisoyan

Environment and Society Faculty Publications

Indigenous to Peru, Chile, and Argentina, the woody plant called Prosopis juliflora (also known by the American common name of “Honey Mesquite”) has spread world-wide in recent decades, including rangelands throughout Latin America, North America, south and central Asia, Australia, and sub-Saharan Africa. A species known for rapid establishment, high adaptability, and fast rates of growth, its dispersal has primarily been a consequence of intentional introduction by well- meaning “technical experts” who wanted to provide a new source of fodder, fuel wood, or a means to combat desertification in arid and semi-arid lands. One problem, however, is that unless Prosopis …


Linking Pastoralists And Exporters In A Livestock Marketing Chain: Recent Experiences From Ethiopia, D. Layne Coppock, Solomon Desta, Getachew Gebru, Seyoum Tezera Dec 2005

Linking Pastoralists And Exporters In A Livestock Marketing Chain: Recent Experiences From Ethiopia, D. Layne Coppock, Solomon Desta, Getachew Gebru, Seyoum Tezera

Environment and Society Faculty Publications

The Boran of southern Ethiopia have been traditionally viewed as unwilling or unable to engage in large scale, commercialized livestock trade. Here we report on the creation of a new livestock marketing chain from the Borana Plateau to export outlets largely serving the Gulf States. Since 2003 various meetings and exchange tours were organized by collaborating agencies and PARIMA to directly link pastoral producers with livestock exporters and policy makers. This occurred against a backdrop of growing export demand for small ruminants, rapid development of private export industry, formation of well-trained pastoral marketing groups (often dominated by women), and provision …


Bromacil, Ecological Risk Assessment, Final Report, Ensr International Nov 2005

Bromacil, Ecological Risk Assessment, Final Report, Ensr International

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

The Bureau of Land Management (BLM), United States Department of the Interior (USDI), is proposing a program to treat vegetation on up to six million acres of public lands annually in 17 western states in the continental United States (US) and Alaska. As part of this program, the BLM is proposing the use of ten herbicide active ingredients (a.i.) to control invasive plants and noxious weeds on approximately one million of the six million acres proposed for treatment. The BLM and its contractor, ENSR, are preparing a Vegetation Treatments Programmatic Environmental Impact Statement (EIS) to evaluate this and other proposed …

Key To Common Indoor Spiders Found In Utah, Alan H. Roe

All Current Publications

This key is intended as an identification aid for spider specimens commonly collected from indoor situations in Utah. It is not all-inclusive and will not correctly identify all spiders. However, the key does include groups that comprise about 90% of the specimens that are submitted from household situations in Utah, and about 80% of spiders submitted from all situations.

Breeding Soundness Evaluation Of Bulls, Clell V. Bagley, C. Kim Chapman Nov 2005

Breeding Soundness Evaluation Of Bulls, Clell V. Bagley, C. Kim Chapman

All Current Publications

Very few bulls are “sterile” and unable to produce any offspring. But, 10% to 25% of bulls have reduced fertility or possess physical problems which reduce their ability to sire calves. The breeding soundness evaluation (BSE) is a useful tool in identifying these bulls. Eliminating bulls with physical problems or reduced fertility from the breeding herd will improve overall reproductive efficiency of the herd.

Microencapsulating Properties Of Trehalose And Of Its Blends With Sucrose And Fructose, Marina Cerdeira, Silvana Martini, Maria L. Herrera Aug 2005

Microencapsulating Properties Of Trehalose And Of Its Blends With Sucrose And Fructose, Marina Cerdeira, Silvana Martini, Maria L. Herrera

Nutrition, Dietetics, and Food Sciences Faculty Publications

A low melting fraction of milk fat (LMF), with a dropping point (MDP) of 16.7 °C, was encapsulated by freeze-drying emulsions formulated with trehalose or its blends with 30 wt% lactose or sucrose as hydrophilic phase, and with a mixed of 50 wt% of the palmitic sucrose esters (SE) β-170 and β-1670 as emulsifiers. Trehalose or trehalose/sucrose matrices were very efficient to encapsulate LMF (retention values were 82.8%± 3.2% and 90.5%± 3.7%, dry basis, respectively), whereas trehalose/lactose showed a significant decline in initial retention (42.5%± 2.5%, dry basis). The role of emulsion stability, water content, physical state of the matrix, …

Structural And Functional Responses Of A Subtropical Forest To 10 Years Of Hurricanes And Droughts, Karen H. Beard Aug 2005

Structural And Functional Responses Of A Subtropical Forest To 10 Years Of Hurricanes And Droughts, Karen H. Beard

Karen H. Beard

Little is known about ecosystem-level responses to multiple, climatic disturbance events. In the subtropical forests of Puerto Rico, the major natural disturbances are hurricanes and droughts. We tested the ecosystem-level effects of these disturbances in sites with different land use histories. From 1989 to 1992, data were collected to determine the effects of Hurricane Hugo and two droughts on litterfall inputs, fine-root biomass, and decomposition rates in three topographic locations (stream, riparian, upslope) within two watersheds. From 1994 to 1998, we added a third watershed and an experiment in which coarse-wood levels were manipulated to simulate hurricane inputs. Data were …
