Can Pastoral Linkages To Livestock Markets Be Sustained In Southern Ethiopia?, D. Layne Coppock, Getachew Gebru, Solomon Desta, Seyoum Tezera, Zewdu Edea Dec 2009

Can Pastoral Linkages To Livestock Markets Be Sustained In Southern Ethiopia?, D. Layne Coppock, Getachew Gebru, Solomon Desta, Seyoum Tezera, Zewdu Edea

Environment and Society Faculty Publications

The PARIMA project has facilitated collective action, empowerment of women, and increased involvement in livestock marketing among pastoralists on the Borana Plateau since 2001. Fifty-nine collective-action groups formed by PARIMA and her partners have been recently merged into market-oriented cooperatives, consistent with government policy. We used focus groups and participatory appraisals to assess the extent that market linkages have been sustained since previously reported in 2006. The markets have been growing, but are volatile. Members report they need access to early warning and livestock market-information systems, as well as more capital, to promote trade. Export firms have imposed added conditions …

Costs Of Implementing Collective Action And Capacity Building Among Pastoralists In Southern Ethiopia, D. Layne Coppock, Seyoum Tezera, Solomon Desta

Environment and Society Faculty Publications

Since 2000, the PARIMA project has implemented risk-management activities among semi-settled pastoralists in southern Ethiopia. The goal has been to improve human welfare via collective action and capacity building. Outcomes include progress in income generation, asset conservation, and livelihood diversification. Fifty-nine collective-action groups were created. Dominated by women, they included over 2,000 founding members and groups have recently merged to form 37 cooperatives, consistent with government policy. Creating sustainable impacts via collective action and capacity building requires many inputs. Taking raw, illiterate volunteers and transforming them into sustainable groups took up to three years, on average. Costs of implementing this …

The PARIMA project was created to improve the well-being of pastoralists and agro-pastoralists in northern Kenya and southern Ethiopia via risk-management research, training, and outreach. The project began to collaborate with Egerton University’s Department of Natural Resources in 1998 and many joint activities were undertaken over the next 11 years. Among them were regional household research on pastoral risks and their management, a training program for Egerton teaching staff to obtain post-graduate degrees, facilitation of Egerton faculty and staff to attend professional meetings, and provision of computer hardware and software that led to the creation of a GIS teaching and …


Simple Cooling Method Improves The Quality Of Marketed Camel Milk In Northern Kenya, D. Layne Coppock, A. O. Adongo, F. Wayua, I. J. Sagalla, H. K. Walaga, C. Amboga Dec 2009

Simple Cooling Method Improves The Quality Of Marketed Camel Milk In Northern Kenya, D. Layne Coppock, A. O. Adongo, F. Wayua, I. J. Sagalla, H. K. Walaga, C. Amboga

Environment and Society Faculty Publications

Milk marketing is important for many pastoralists to generate income, especially poor households with little else to sell. Milk is accumulated at pastoral settlements and transported to local markets on foot, by pack animals, or in vehicles. Despite challenges of heat and long-distance travel, pastoralists or traders do not attempt to cool marketed milk and possibly reduce risk of spoilage. Milk spoilage is an important problem that limits urban consumer demand. Our research objective was to determine effects of water-soaked hemp (burlap), wrapped around plastic jerry cans, on reducing milk temperature and enhancing quality of marketed camel milk, a key …

Subcutaneous Administration Of Tc007 Reduces Disease Severity In An Animal Model Of Sma, Virginia B. Mattis, Marina Y. Fosso, Cheng-Wei Tom Chang, Christian L. Lorson Nov 2009

Subcutaneous Administration Of Tc007 Reduces Disease Severity In An Animal Model Of Sma, Virginia B. Mattis, Marina Y. Fosso, Cheng-Wei Tom Chang, Christian L. Lorson

Chemistry and Biochemistry Faculty Publications

Background Spinal Muscular Atrophy (SMA) is the leading genetic cause of infantile death. It is caused by the loss of functional Survival Motor Neuron 1 (SMN1). There is a nearly identical copy gene, SMN2, but it is unable to rescue from disease due to an alternative splicing event that excises a necessary exon (exon 7) from the majority of SMN2-derived transcripts. While SMNΔ7 protein has severely reduced functionality, the exon 7 sequences may not be specifically required for all activities. Therefore, aminoglycoside antibiotics previously shown to suppress stop codon recognition and promote translation read-through have been examined to increase the …


Regional Assessment Of Aspen Change And Spatial Variability On Decadal Time Scales, Temuulen Tsagaan Sankey Nov 2009

Regional Assessment Of Aspen Change And Spatial Variability On Decadal Time Scales, Temuulen Tsagaan Sankey

Aspen Bibliography

Quaking aspen (Populus tremuloides) is commonly believed to be declining throughout western North America. Using a historical vegetation map and Landsat TM5 imagery, this study detects changes in regional aspen cover over two different time periods of 85 and 18 years and examines aspen change patterns with biophysical variables in the Targhee National Forest of eastern Idaho, USA. A subpixel classification approach was successfully used to classify aspen. The results indicate greater spatial variability in regional aspen change patterns than indicated by local-scale studies. The observed spatial variability appears to be an inherent pattern in regional aspen dynamics, …

Effect Of Self-Determination Theory-Based Strategies For Staging Recreation Encounters On Intrinsic Motivation Of Youth Residential Campers, Mark F. Roark, Gary D. Ellis Oct 2009

Effect Of Self-Determination Theory-Based Strategies For Staging Recreation Encounters On Intrinsic Motivation Of Youth Residential Campers, Mark F. Roark, Gary D. Ellis

Kinesiology and Health Science Faculty Publications

Parents and caregivers generally believe that the camp experiences they purchase for their children will not only yield transient pleasure and lasting memories of fun encounters, but significant developmental outcomes as well. Camp professionals serving over 11 million youths each year embrace such outcomes and commonly advance mission statements that point to the development of friendship skills, self-confidence, competence, self-reliance, independence, citizenship, and many other developmental outcomes. Empirical evidence of how these outcomes might be facilitated through specific recreation leadership strategies (e.g., activity staging) is lacking. The Self-Determination Theory (SDT) would suggest that youth leaders (e.g., camp counselors, recreation activity …


Scared Sick? Predator-Pathogen Facilitation Enhances The Exploitation Of A Shared Resource, Ricardo A. Ramirez, W E. Snyder Oct 2009

Scared Sick? Predator-Pathogen Facilitation Enhances The Exploitation Of A Shared Resource, Ricardo A. Ramirez, W E. Snyder

Biology Faculty Publications

Resource use generally increases with greater consumer diversity, an effect often attributed to resource partitioning. Pathogens and predators are two classes of consumer that exhibit differences in ecologically important traits (e.g., size, resource acquisition strategy, foraging location) that could lead to complementary effects on shared prey/hosts. To examine this possibility, we manipulated diversity among a community of predators and pathogens that together attack an herbivorous beetle, Leptinotarsa decemlineata, and measured resulting effects on herbivore suppression and resulting plant damage. We found that herbivore mortality increased, and plant damage decreased, when more natural enemy species were present. However, closer examination revealed …

Consequences Of Recruitmentdecisions And Heterogeneity On Age-Specific Breeding Success In A Long-Lived Seabird, Lise M. Aubry, David N. Koons, Jean Yves Monnat, Emmanuelle Cam Sep 2009

Consequences Of Recruitmentdecisions And Heterogeneity On Age-Specific Breeding Success In A Long-Lived Seabird, Lise M. Aubry, David N. Koons, Jean Yves Monnat, Emmanuelle Cam

Wildland Resources Faculty Publications

An individual’s age at first reproduction and investment in successive reproductive attempts are involved in mechanisms that can impede somatic repair, resulting in a decline in reproductive abilities with age (reproductive senescence). We used long-term data from the Black-legged Kittiwake, a long-lived seabird, to address the relationship between recruitment age, age-specific breeding success (BS), and reproductive senescence, while accounting for breeding experience and temporal variation in BS. We first detected late-life improvement in BS across all recruitment groups, which we recognized as ‘‘within-generation selection’’ or the selective disappearance of ‘‘frail’’ phenotypes. When such heterogeneity was accurately accounted for, we showed …


Energy Budgets Of Eared Grebes On The Great Salt Lake And Implications For Harvest Of Brine Shrimp, Michael R. Conover, Joe N. Caudell Sep 2009

Energy Budgets Of Eared Grebes On The Great Salt Lake And Implications For Harvest Of Brine Shrimp, Michael R. Conover, Joe N. Caudell

Wildland Resources Faculty Publications

About 1.5-million eared grebes (Podiceps nigricollis), representing half of the North American population, stage on Utah's Great Salt Lake, USA (GSL) during autumn migration to forage on brine shrimp (Artemia franciscana). Indirectly competing with birds for brine shrimp are commercial harvesters who annually collect >1 million kg (dry wt) of shrimp cysts (i.e., hardened eggs), an amount that during some years equals up to half of all brine shrimp cysts produced annually on the GSL. No information was available regarding what impact this commercial harvest was having on eared grebes. We determined daily energy requirements of eared grebes so that …

Silviculture Certification Revalidation Case Studey : An Assessment Of Aspen Regeneration By Fire Intensity Following Prescribed Burning On Low Productivity Sites In Southwest Idaho And/Or A Simplistic Model Showing Aspen Sprouting Response By Varying Degrees Of Fire Intensity As Defined By Degree Of Aspen Crown-Kill Within The Lime Creek Aspen Restoration Project Area, Steven L. Williams

Aspen Bibliography

This Case Study is prepared for revalidation as a certified silviculturist in the Intermountain Region. When I first began working on this study, I anticipated that prescribed fire would produce variable degrees of aspen crown-kill and that differences in aspen sprouting would exist across the project area. What I observed was that although variable degrees of aspen crown-kill do exist, their distribution and relative amounts is more a function of prescribed fire ignition than of vegetation conditions. Very nearly full aspen crown-kill occurs with any fire that sustains itself enough to carry through the vegetation. Where prescribed fire is employed, …
