Conservation of soil organic carbon, biodiversity and the provision of other ecosystem services along climatic gradients in West Africa por Marks, E., Aflakpui, G.K.S., Nkem, J., Poch, R.M., Khouma, M., Kokou, K., Sagoe, R., Sebasti`a, M.T.

“…Among biotic factors, biodiversity conservation paired with carbon conservation may provide a pathway to sustainable development, and biodiversity conservation is also a global priority with local benefits for ecosystem resilience, biomass productivity, and provisioning services such as foodstuffs. Finally, human management has largely been responsible for reduced carbon stocks, but this trend can be reversed through the implementation of appropriate carbon conservation strategies in the agricultural sector, as shown by multiple studies. …”

Detecting large-scale diversity patterns in tropical trees: can we trust commercial forest inventories? por Réjou-Méchain, M., Fayolle, A., Nasi, Robert, Gourlet-Fleury, S., Doucet, J.L., Gally, M., Hubert, D., Pasquier, A., Billand, A.

“…Contrary to a widespread belief, we did not find a strong bias toward commercial species, showing that commercial inventory data could also be valid for non-commercial species in ecological studies. Finally, we found that both alpha and beta diversity patterns in commercial inventories were highly consistent with those of the re-sampled inventory. …”

Multiple use management of tropical production forests: How can we move from concept to reality? por Guariguata, Manuel R., Sist, P., Nasi, Robert

“…For managers and practitioners to work on multiple forest use in the tropics they must consider spatial aspects in detail, from the stand to the landscape. Finally, moving from “concept to reality” will also require new forestry training and education approaches to keep up with the ever-growing methods for valuing and using tropical forests.…”

Assessing health risk due to exposure to arsenic in drinking water in Hanam Province, Vietnam por Huy-Tung, B., Tuyet-Hanh Tran Thi, Hung Nguyen-Viet

“…Health risk was characterized by comparing the As levels in water with the National technical regulations on drinking water quality, and by comparing the daily consumption dose with the Tolerable Daily Intake (TDI) value set by WHO. Finally, cancer risk of people using As contaminated water source for eating and drinking was estimated using Cancer Slope Factor index and lifetime average daily dose. …”

IgG antibodies from dourine infected horses identify a distinctive Trypanosoma equiperdum antigenic pattern of low molecular weight molecules por Luciani, M., Pancrazio, C. Di, Febo, T. Di, Tittarelli, M., Vulpiani, M.P., Puglielli, M.O., Naessens, Jan, Sacchini, F.

“…Sera were compared by the complement fixation test (CFT), indirect immune fluorescence (IFA) and the cIB assay. cIB analysis revealed that IgGs from infected horses, in contrast to IgGs from healhty horses, specifically recognise a T. equiperdum antigenic profile with low molecular weight bands ranging between 16 and 35 kDa. …”

Risk assessment in the pork meat chain in two districts of Viet Nam por Fahrion, Anna S., Grace, Delia, Toan Nguyen Ngoc, Thuy Do Ngoc, Staal, Steven J., Lapar, Ma. Lucila

“…We also report on the prevalence of consumer practices around purchase, keeping and preparation of food which are likely to influence risk. Finally, we integrate the findings from the different levels of the chain to assess the risk to consumers and conclude that although there is strong evidence for high levels of hazards in pork, there is less evidence of high levels of risk to consumers of pork meat.…”

An in vitro assay for drug sensitivity of Trypanosoma congolense using in vitro-derived metacyclic trypanosomes por Gray, M.A., Peregrine, A.S.

“…IL 3274 and IL 3330, characterised as expressing high levels of resistance to all three drugs in vivo, were shown to be resistant to isometamidium chloirde and homidium salts at 1000 ng/ml, and to diminazene aceturate at 10 000 ng/ml. Finally, the in vitro IC 100 (concentration of drug required to eliminate 100 percent of the population) results were consistent with the maximum amounts of each drug detected in vivo.…”

Variation in resistance to isometamidium chloride and diminazene aceturate by clones derived from a stock of Trypanosoma congolense por Peregrine, A.S., Knowles, G., Ibitayo, A.I., Scott, J.R., Moloo, S.K., Murphy, N.B.

“…This contrasts with doses of 0·25 mg/kg isometamidium chloride or 3·5 mg/kg diminazene aceturate which are deemed sufficient to cure fully sensitive infections. Finally, 9 clones (subclones) were derived from IL 3270 and characterized in mice for their sensitivity to isometamidium chloride. …”

Concentrations of isometamidium in the sera of cattle challenged with drug-resistant Trypanosoma congolense por Eisler, M.C., Gault, E.A., Moloo, S.K., Holmes, P.H., Peregrine, A.S.

“…Thus, differences in susceptibility to challenge at this time would appear to be due to differences in the drug sensitivity of the parasite challenge. Finally, the mean isometamidium concentration in uninfected cattle at the time of the fourth monthly challenge was 0.4 (+ or -) 0.18 ng/ml. …”

Impact assessment of input and output market development interventions by IPMS Project: The case of Gomma Woreda por Tolemariam, A.

“…In order to alleviate access to market, establishing farmers’ cooperatives and linking this cooperatives or individual farmers to potential buyers (including exporters) was done. The thesis finally discusses these results in detail and draws some recommendations.…”

EcoHealth research in Southeast Asia: Past, now, and the ways forward por Hung Nguyen-Viet, Gilbert, Jeffrey, Dinh Xuan Tung, Mallee, H., Unger, Fred, Grace, Delia

“…However, the challenges remain at the project design and implementation level but also on the available capacity and coordination to develop EcoHealth research and teams in the countries as well as the issue of EcoHealth scaling-up. Finally we will present the ways forward of EcoHealth from a regional perspective in terms of research, training and policy translation using EcoHealth in combination with One Health approach.…”

Constraints and opportunities for water savings and increasing productivity through Resource Conservation Technologies in Pakistan por Ahmad, M.D., Masih, I., Giordano, Mark

“…The study also indicates that the field scale reduction in irrigation application did not always translate into real water savings or reductions in water use at farm, cropping system and catchment scales, especially in areas where deep percolation from the root zone could be reused as groundwater irrigation. Finally, the evidence shows that medium and large farmers tended to use the field scale irrigation savings to increase their cropped area. …”

WETwin: a structured approach to evaluating wetland management options in data-poor contexts por Johnston, Robyn M., Cools, J., Liersch, S., Morardet, S., Murgue, C., Mahieu, Marie, Zsuffa, I., Uyttendaele, G.P.

“…The approach used in WETwin has three important strengths: it involves stakeholders at all stages of the decision process, it combines qualitative and quantitative data (and therefore allows inclusion of poorly known and potentially important system components) and finally, it provides a relatively simple and structured approach to evaluate wetland management interventions and integrate impact, feasibility and institutional assessments, vulnerability analysis and trade-off analysis. …”
