Riparian meadows occupy a small proportion of the public lands in the western United States but they provide numerous ecosystem services, including the production of high-quality forage for livestock grazing. Modern conservation management strategies (e.g., reductions in livestock stocking rates and adoption of new riparian grazing standards) have been implemented to better balance riparian con...
To characterise the urban livestock keeping practices and constraints in Kisumu municipality, Kenya, a questionnaire survey was carried out. Thirty-four contact farmers were interviewed on general farm characteristics and production constraints. The farming activities were categorised as either livestock only (41%), or mixed crops and livestock (59%). The surveyed farmers kept mainly cattle (10...
Pastoralists in the wildlife-rich East African rangelands use diversification into conservation and tourism as a strategy to supplement livestock-based livelihoods and to spread risk. Tourism incomes are an important alternative source during drought, when livestock incomes decline. However, tourism may also reduce access to rangeland resources, and an abundant wildlife may destroy crops and in...
Frontiers in Livestock Genomics (FLG) provides a venue for investigators to publish basic, applied, and methodological research toward a better understanding of the genetic mechanisms underlying the expression of complex phenotypes in livestock, the effects of domestication and evolutionary processes on genome variability, as well as innovative strategies for the genetic improvement of economic...
Abstract This paper reviewed the studies of livestock odour dispersion modeling including odor sources, odor emission rate, odor characteristics and measurements, odor dispersion modeling methods, and methods and results of adapting industrial air dispersion models for livestock odor dispersion simulations. The Gaussian plume models, Puff models, Fluctuating models and other models that have be...
The authors are scientists working on the epidemiology of livestock diseases such as foot and mouth disease and bovine tuberculosis. The authors are also part of Governance of Livestock Disease project, funded by the Rural Economy and Land-Use (RELU) programme, and are responding on behalf of the project. Livestock movement data, provided latterly via RADAR, have proved very valuable in enhanci...

This research surveyed over 784 Chinese consumers in Shanghai and Nanjing in 2001 and 2002, evaluating their preferences for livestock product attributes using ordered-probit models and factor analyses. Empirical results confirm the heterogeneity of Chinese livestock retail markets and suggest that livestock distributors should focus on Chinese female consumers and young consumers considering c...
Angiosperms diversification was primarily driven by pollinator agents, but non-pollinator agents also promoted floral evolution. Gentiana lutea shows pollinator driven flower color variation in NW Spain. We test whether insect herbivores and livestock, which frequently feed in G.lutea, play a role in G. lutea flower color variation, by answering the following questions: (i) Do insect herbivores...
Little is known about the factors affecting pastoralists' livestock vaccination decisions. In this thesis, we use a novel survey-based dataset on pastoralists living in the Ruaha landscape in Tanzania, and employ several econometric approaches to identify the factors affecting pastoralists' decision-making process about livestock vaccination when disease occurrence and severity, vaccination and...
