Arbuscular mycorrhizal fungi in Mimosa tenuiflora (Willd.) Poir from Brazilian semi-arid BJM
Souza,Tancredo Augusto Feitosa de; Rodriguez-Echeverría,Susana; Andrade,Leonaldo Alves de; Freitas,Helena.
Abstract Many plant species from Brazilian semi-arid present arbuscular mycorrhizal fungi (AMF) in their rhizosphere. These microorganisms play a key role in the establishment, growth, survival of plants and protection against drought, pathogenic fungi and nematodes. This study presents a quantitative analysis of the AMF species associated with Mimosa tenuiflora, an important native plant of the Caatinga flora. AMF diversity, spore abundance and root colonization were estimated in seven sampling locations in the Ceará and Paraíba States, during September of 2012. There were significant differences in soil properties, spore abundance, percentage of root colonization, and AMF diversity among sites. Altogether, 18 AMF species were identified, and spores of...

Conservation tillage and controlled traffic AgEcon
The following review is an financial assessment of an Australian Centre for International Agricultural Research (ACIAR) conservation tillage and controlled traffic research project which was conducted in China (for the conservation tillage component) and Australia (for the controlled traffic component) during the period 1993–1996, inclusive. The project—No. 9209—was implemented by staff from the Beijing Agricultural and Engineering University and the Shanxi Agricultural Machinery Bureau (in China) and the University of Queensland (in Australia). The overall aim of the joint project was to develop and evaluate conservation and zone (controlled traffic) tillage techniques for sustainable dryland grain production in China and Australia. Australian dryland...

Dryland Wheat variety selection in the Texas High Plain AgEcon
Park, Seong Cheol; Cho, Jaesung; Bevers, Stanley J.; Amosson, Stephen H.; Rudd, Jackie C..
Selecting the best wheat varieties affects producers’ profit and financial risk. This study identifies the optimal wheat variety selection using the portfolio approach at various risk aversion levels. Results showed that the optimal wheat variety selection was significantly affected by changes in levels of risk aversion of decision makers

Forest Landscape Restoration in the Drylands of Latin America Ecology and Society
Newton, Adrian C; Bournemouth University, Bournemouth, UK; anewton@bournemouth.ac.uk; Premoli, Andrea C; Laboratorio Ecotono, Universidad Nacional del Comahue, Bariloche, Argentina; andrea.premoli@gmail.com.
Forest Landscape Restoration (FLR) involves the ecological restoration of degraded forest landscapes, with the aim of benefiting both biodiversity and human well-being. We first identify four fundamental principles of FLR, based on previous definitions. We then critically evaluate the application of these principles in practice, based on the experience gained during an international, collaborative research project conducted in six dry forest landscapes of Latin America. Research highlighted the potential for FLR; tree species of high socioeconomic value were identified in all study areas, and strong dependence of local communities on forest resources was widely encountered, particularly for fuelwood. We demonstrated that FLR can be achieved through both...
