Estimation of Biomass Carbon Stocks over Peat Swamp Forests using Multi-Temporal and Multi-Polratizations SAR Data por Wijaya, A., Liesenberg, V., Susanti, A., Karyanto, O., Verchot, Louis V.

“…This is probably due to the fact that land cover change in the area from 2007 – 2009 was highly dynamic, converting natural forests into rubber and Acacia plantations, thus SAR data of 2010 which was acquired in between of two field campaigns has provided significant results (F = 40.7, P < 0.005). …”

El consumo de carnes en Argentina 1950-2012 por Reca, Lucio Graciano, Lema, Rolando Daniel

“…The analysis is part of a panoramic view of the evolution of the main sources of animal protein in the last six decades. Four relevant changes are identified in this study: (i) a gradual fall in the beef share of total meat consumption, (ii) a lower variability in the beef consumption, (iii) the development of industrial poultry production and, (iv) an improvement in swine production in recent years. …”

Genetic progress and economic benefit of community-based breeding programs for sheep out- and upscaling options in Ethiopia por Mueller, Joaquin Pablo, Haile, Aynalem, Getachew, Tesfaye, Rekik, Mourad, Rischkowsky, Barbara

“…Considering a shorter planning horizon (H = 10) and a larger discount rate (r = 0.12) would reduce benefits and returns to investment but would not change the general finding that out-scaling current CBBPs or upscaling the number of improved males from current CBBPs for dissemination are highly recommendable strategies for livestock development. …”

Analysis of factors controlling maize yield response to hairy vetch and to nitrogen fertilization after hairy vetch por Carciocchi, Walter Daniel, Cafaro La Menza, Nicolás, Crespo, Cecilia, Domínguez, Germán, Rodríguez, M.P., Reussi Calvo, Nahuel Ignacio, Wyngaard, Nicolás, Sainz Rozas, Hernan Rene, Studdert, Guillermo, Barbieri, Pablo

“…Nitrogen supply from HV was the main factor determining variations in grain yield response to HV, although factors other than N (e.g., water availability, changes in soil physical and biological properties) presented a significant effect (avg. 366 kg ha−1). …”

Genome-enabled and phenotypic selection of alfalfa for widely-diversified cropping environments por Annicchiarico, Paolo, Nazzicari, Nelson, Bouizgaren, Abdelaziz, Hayek, Taoufik, Laouar, Meriem, Cornacchione, Monica, Basigalup, Daniel Horacio, Brummer, Edward Charles, Pecetti, Luciano

“…The decrease of rainfall amount due to climate change, and the reduction of irrigation water caused by growing water demand for non-agricultural uses, emphasize the importance of breeding novel alfalfa varieties that are more tolerant to drought under rain-fed cropping or modest supplemental irrigation, and more tolerant to salt to exploit low-quality, saline irrigation water. …”

Feedbase intervention in a cow-calf system in the flooding pampas of Argentina: 2. Estimation of the marginal value of additional feed por Berger, Horacio, Bilotto, Franco Maximiliano, Bell, Lindsay, Machado, Claudio

“…Overall, the framework developed by integrating forage, livestock and economic models “in a series” effectively identified the economic feasibility of changes to the farm feed-base under different climatic and livestock management conditions.…”

Plant nitrogen status at flowering and kernel set efficiency in early- and late-sown maize crops por Maltese, Nicolás, Maddonni, Gustavo Angel, Melchiori, Ricardo Jose, Caviglia, Octavio

“…Additionally, PGR can be differentially affected by environmental conditions (e.g. sowing dates) through indirect effects on plant size or directly, which could determine changes on KSE. Field experiments were carried-out in Paraná (31° 48' S, 60° 32' W), Argentina, during two growing seasons (2014−15 and 2015−16). …”

Impact of bush fire on grazing behaviour of herbivores in Masai Mara por Wagner, Maria

“…Since different herbivore species have different demands on amount and quality of biomass, bush fires might change the composition of the herbivore community. …”

Skogsbristen i Smålands bruksskogar por Hedström, Ida

“…In the study, I made a selection of 16 villages to analyse how the charcoal deliveries varied between the villages, also how these deliveries changed over time. From 1793 to 1850 the farmers around the ironworks, in average, delivered 94 100 hectolitres of charcoal per year to the ironworks, which corresponds to an annual felling of 11 292 m3. …”
