1. Straw management effects on sugarcane growth, nutrient cycling and water use in the Brazilian semiarid region
ABSTRACT It was evaluated how straw management modifies the development, growth, nutrient cycling and crop water productivity of sugarcane in the semiarid region of Brazil. The experiment was carried out using two plots with 5 ha each, being one without straw on the soil surface and one with 26 Mg·ha-1 covering the soil. Sugarcane growth and development and

2. Modelling beef cattle production systems from the Pampas in Brazil to assess intensification options
ABSTRACT Traditional livestock productivity is hard to estimate, since it depends on a gamut of animal production indicators that are difficult to measure for many farms. Thus, we propose an analytical method for estimating productivity and understanding the importance of animal production indicators under different full-cycle cattle production systems in Br

3. Does high stereotypic behavior expression affect productivity measures in sows?
ABSTRACT The objective of this study was to evaluate the effects of stereotypic behavior on productivity measures in sows. Frequent expression of stereotypies by pigs has been reported, even when pigs are not maintained in crates. This behavior is only observed in animals kept in captivity and is a wide-range welfare indicator, since it is considered to deve

4. Performance and grazing behavior of growing goats supplemented with palm tree fruit
ABSTRACT This study aimed to evaluate the performance and ingestive behavior of growing goats grazing on Tanzania guinea grass and fed diets containing 40% carnauba or tucum fruits. Twenty-one male castrated goats were distributed into three groups, one exclusively on pasture and the other two on pasture and fed diet supplemented at the level of 1.5% body we

6. Multi-criteria decision analysis and spatial statistic: an approach to determining human vulnerability to vector transmission of Trypanosoma cruzi
BACKGROUND Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a neglected human disease. It is endemic to the Americas and is estimated to have an economic impact, including lost productivity and disability, of 7 billion dollars per year on average. OBJECTIVES To assess vulnerability to vector-borne transmission of T. cruzi in domiciliary

7. Barium and its Importance as an Indicator of (Paleo)Productivity
ABSTRACT Barium (Ba) is a trace element which occurs predominantly as barite mineral (BaSO4) in the marine environment. Previous work suggests that barite concentrations are related to the organic carbon flux and marine biological debris in the water column suggesting a direct or indirect involvement in the marine biological cycling. In addition, barite has

8. Effects of forest structure on litter production, soil chemical composition and litter-soil interactions
ABSTRACT Litter production in forest ecosystems is a major indicator of primary productivity because litter helps incorporate carbon and nutrients from plants into the soil and is directly involved in plant-soil interactions. To our knowledge, few studies have investigated the relationship between species diversity and ecosystem processes in subtropical fore

10. Intensificación agrícola y pérdida de servicios ambientales en el partido de Azul (Provincia de Buenos Aires) entre 2002-2011
In recent decades, Argentinean agriculture, especially in the Pampas ecoregion, has undergone a remarkable expansion based on technological development. This process allows increasing productivity but it increases costs in terms of loss of environmental services. This paper aims at analyzing the loss of some support and regulation services in the period 2002
