Marker-assisted selection: an approach for precision plant breeding in the twenty-first century por Collard, Bertrand C. Y., Mackill, David J.

“…We also consider reasons why MAS has had only a small impact on plant breeding so far and suggest ways in which the potential of MAS can be realized. Finally, we discuss reasons why the greater adoption of MAS in the future is inevitable, although the extent of its use will depend on available resources, especially for orphan crops, and may be delayed in less-developed countries. …”

Microsatellite analysis revealed genetic diversity and population structure among Chinese cashmere goats por Di, R., Vahidi, S.M.F., Ma, Y.H., He, X.H., Zhao, Q.J., Han, J.L., Guan, Wei-Jun, Chu, M.X., Sun, W., Pu, Y.P.

“…All pairwise FST values between the Chinese cashmere goat populations reached a highly significant level (P < 0.001), suggesting that they should all be considered as separate breeds. Finally, clustering analysis divided Chinese cashmere goats into at least two clusters, with the Tibetan Hegu goats alone in one cluster. …”

From "participation" to "rights and responsibilities" in forest management: workable methods and unworkable assumptions in West Kalimantan, Indonesia por Colfer, C.J.P., Wadley, R.L.

“…Important remaining policy-related issues include the variations in quality of local management systems, values held by the different stakeholders, and potential productivity of individual systems. Finally it concludes that, given the dynamism and complexity that characterise natural forests and their inhabitants, cooperation among all stakeholders in an ongoing dialogue is most likely the only way that sustainable forest management can in fact occur.…”

Acteurs locaux, representation et politics des eco-pouvoirs dans le Cameroun rural post-1994 por Oyono, P.R.

“…They then explore the results generated by the “powers game” and local politics before assessing the role of local representatives — management committees — in the dynamics at work. Finally, working from the assumption that the observed limits arise to a large extent from the lack of benchmarks for decentralized management, the author proposes a research approach generally based on identifying indicators for monitoring the exercise of powers over the forest environment and forestry revenue.…”

Agrarian change, cattle ranching and deforestation: Assessing their linkages in Southern Para por Pacheco, P.

“…The process of land occupation and agrarian development has inevitably led to forest conversion mainly to pasture. Finally, environmental policies seeking to halt deforestation have been largely ineffective under these conditions of frontier development.…”

Forest biodiversity and the delivery of ecosystem goods and services: translating science into policy por Thompson, I.D., Okabe, K., Tylianakis, Jason M., Kumar, P., Brockerhoff, E.G., Schellhorn, Nancy A., Parrotta, J.A., Nasi, Robert

“…Focusing on forest and agroforest systems, we synthesize recent research on the role of biodiversity in the provision of ecosystem services and provide examples of biodiversity science that informs ecosystem management and policy. Finally, we highlight barriers to the transfer of knowledge from scientists to decisionmakers and suggest that scientists can be much more effective at informing policy and improving resource management by asking policy-relevant questions and providing timely and consistent information to decisionmakers and the public on the linkages among biodiversity, ecosystem services, and their value to people.…”

Epidemiology of bovine trypanosomiasis in the Ghibe Valley, southwest Ethiopia. 1. Tsetse challenge and its relationship to trypanosome prevalence in cattle por Leak, S.G.A., Mulatu, W., Authié, Edith, D'Ieteren, G.D.M., Peregrine, A.S., Rowlands, G.J., Trail, J.C.M.

“…The tsetse density at both sites showed seasonal changes which were related to the monthly rainfall. Finally, variations in tsetse density appeared to be the main factor responsible for variation in tsetse challenge and thus trypanosome prevalence in cattle.…”

Managing animal trypanosomosis in Africa: Issues and options por Omamo, Steven Were, D'Ieteren, G.D.M.

“…In addition, ways of achieving greater coherence between research and policy-making must be explored. Finally, the social science issues raised by the question of which practical steps need to be taken to manage trypanosomosis in Africa should be placed at the forefront of research efforts.…”

Comparing apples and oranges - model-based assessment of different tsetse-transmitted trypanosomosis control strategies por McDermott, John J., Coleman, P.G.

“…Differences in the predicted impact of control measures on the transmission of human sleeping sickness are discussed. Finally, the role of transmission model outputs as inputs for economic models to guide investment decisions for trypanosomosis control is emphasised.…”
