1. Inferring mating system parameters in forage peanut, Arachis pintoi, for Brazilian Amazon conditions
RESUMO A busca por alternativas para aumentar a produtividade e a sustentabilidade da pecuária na região Amazônica sem aumentar o desmatamento é desafiadora. Pastagens consorciadas de gramíneas com amendoim forrageiro (Arachis pintoi) têm mostrado impactos econômicos positivos. Porém, lacunas no conhecimento da biologia reprodutiva do amendoim forrag

2. Diagnostic fingerprints ISSR/SSR for tropical leguminous species Stylosanthes capitata and Stylosanthes macrocephala
ABSTRACT: Stylosanthes capitata Vogel and Stylosanthes macrocephala M.B.Ferreira & Sousa Costa are two forage leguminous species of agronomic importance for animal husbandry in tropical environments. The physical mixture of both species (80 % S. capitata and 20 % S. macrocephala) comprises the commercial cultivar “Estilosantes Campo Grande”. However, pro

3. Soil conservation management with cover crops: effects on critical energy levels, release and dispersion of aggregates
ABSTRACT The normalized dispersion index (NDI) and the b/a index are commonly used to express the stability of aggregates measured by ultrasound. However, few studies have used the critical energy (CE) extracted from modeling to explain the effects of soil use and management on soil aggregation. The objective of this study was to evaluate the influence of so

4. Genetic diversity assessed by microsatellite markers in the amphicarpic species Trifolium polymorphum Poir.
ABSTRACT Trifolium polymorphum Poir. is an amphicarpic forage legume from southern Brazil, Uruguay, Argentina, Paraguay and Chile. Information on the genetic diversity of natural populations in natural grasslands in southern Brazil is limited. In order to increase the knowledge about this species, an analysis of the genetic diversity was carried out in 10 na

5. Organography of greenhouse and field accessions of wild Arachisspecies (section Arachis)
ABSTRACT Peanut or groundnut (Arachis hypogaea L.) is a globally important oilseed crop, with important nutritional qualities, and a rich source of amino acids and protein. Another 80 species have been described in the genus Arachis, 64 of which are found in Brazil, and even though their morphology and agronomic traits remain largely unknown, they have been

6. Effects of Soil Management Practices on Water Erosion under Natural Rainfall Conditions on a Humic Dystrudept
ABSTRACT Water erosion is the main cause of soil degradation and is influenced by rainfall, soil, topography, land use, soil cover and management, and conservation practices. The objective of this study was to quantify water erosion in a Humic Dystrudept in two experiments. In experiment I, treatments consisted of different rates of fertilizer applied to the

7. Seasonal habitat selection of the red deer (Cervus elaphus alxaicus) in the Helan Mountains, China
We studied the seasonal habitat selection of the red deer, Cervus elaphus alxaicus Bobrinskii & Flerov, 1935, in the Helan Mountains, China, from December 2007 to December 2008. Habitat selection varied widely by season. Seasonal movements between high and low elevations were attributed to changes in forage availability, alpine topography, the arid climate o

8. Using genetic diversity information to establish core collections of Stylosanthes capitata and Stylosanthes macrocephala
Stylosanthes species are important forage legumes in tropical and subtropical areas. S. macrocephala and S. capitata germplasm collections that consist of 134 and 192 accessions, respectively, are maintained at the Brazilian Agricultural Research Corporation Cerrados (Embrapa-Cerrados). Polymorphic microsatellite markers were used to assess genetic diversity

9. Microsatellite diversity and chromosome number in natural populations of Trifolium riograndense Burkart
Twenty eight natural populations of Trifolium riograndense Burkart, an important forage legume from native pastures of the state of Rio Grande do Sul, Brazil, were evaluated for genetic diversity with eight Simple Sequences Repeats (SSR) markers. Chromosome numbers were also determined. The eight markers were polymorphic, with 35 alleles and an average of 4.

10. A intensificação da agricultura e o papel de árvores isoladas na conservação da fauna de formigas do cerrado fora de unidades de conservação / The intensification of agriculture and the role of isolated trees in the conservation of savanna ant assemblages outside protected areas
The destruction of natural habitats and the intensification of agriculture are considered the major threats to biodiversity conservation. Given the rapid expansion of agricultural frontiers in the areas of native vegetation in the Cerrado, it is imperative to know the capacity of conservation of the native fauna in agroecosystems. Thus, this study aims to de

12. Algumas informações sobre a produção e o armazenamento de sementes de Cratylia argentea.
ABSTRACT: Cratylia argentea is a promising shrub forage legume native of Cerrado ecosystem. Information concerning the reproductive phenology, seed morphology, and seed production and storage are presented. Seed production varies with genotype, age, and spacing of the plants. Seeds of Cratylia argentea can be harvested manually, sun dried and hand cleaned. S
