Many sources of pollution, including agricultural, industrial, and urban sources, can increase a stream or lake's nutrient and bacterial concentrations. In order to improve water quality, these sources must be identified, and microbial source tracking (MST) methods are currently…
This dissertation is a case study of the potential economic benefits that could accrue to a traditional pastoral society if attempts were made to diversify assets to include nonpastoral investment such as simple savings accounts in banks or community credit unions. Broad socioec…
This thesis presents the history of the development of range management in Morocco and a case study of indigenous range management in southern Morocco based on nearly three years of archival and field research in Morocco and France. Despite the ubiquitous claims of overgrazing a…
A field survey and a metabolism experiment were conducted to study livestock watering practices in the Moroccan Pre-Sahara and their changes with drought extent, season, ecological zone, pastoral system and herd size. The metabolism experiment was designed to determine effects o…
This project analyzes the potential of wildlife to consume and disperse viable leafy spurge (Euphorbia esula L.) and other forage seeds within their feces. Controlled feeding trials were used to determine the effect that gastrointestinal tract passage through deer, grouse and tu…
This dissertation contributes to the debate on Common Pool Natural Resources (CPNRs) through the analysis of a specific case study: rangeland in southwest agro-pastoral Niger. The management of CPNRs is the subject of a lively debate pertaining to the property rights regime that…
The objectives of this study were: (1) to develop viable habitat suitability models for two endangered species of wildlife, the Sumatran rhinoceros and the Sumatran elephant, in Kerinci Seblat National Park; and (2) to identify potential applications of the models in the develop…
Yellow bluestem (Bothriochloa ischaemum (L.) Keng.) cultivars are used in conservation plantings in New Mexico, Texas and Oklahoma. The recommended cultivar in southern Arizona is Ganada. However, a population from Saudi Arabia P.I. 237110, may be better adapted to the Sonoran D…
The potential of NIRS fecal profiling to predict crude protein (CP) and digestible organic matter (DOM) in the diet of free-ranging sheep and cattle, and condensed tannins in the diet of sheep, in sub-Saharan Africa (SSA), was examined. The calibration sets comprised of samples …

During the sixteenth and seventeenth centuries, Muslim corsairs carried out near-constant raids of Spain’s coast and returned to North Africa with captured Spaniards to either ransom or sell as slaves. However, Muslim corsairs and slave-masters also frequently offered their capt…
Rangeland degradation is one form of desertification that has been accelerating in different parts of the world particularly in the arid and semi-arid regions where pastoral economies prevail. The Sultanate of Oman is located in the arid region of Southwest Asia. The Southern Re…
I tested the hypotheses that competition, shade, and drought favor large seeds, in annual grasslands. Most seed ecologists have employed invalid methodology, often confusing mass and number, and drawn insupportable conclusions. There is good empirical evidence that shade and com…
The effects of Stylosanthes hamata sown in pastures on liveweight changes of bulls grazing in dry season native pasture were studied. Native pasture interseeded completely with Stylosanthes hamata and native pasture sown with Stylosanthes hamata in strips were grazed and results…
