Assessment of Influence and Inter-Relationships of Soil Properties in Tropical Grasslands of Central India CIGR Journal
goroshi, sheshakumar k.
The present experiment was carried out to assess influence and inter-relationships of soil properties in grasslands of three wildlife protected national parks in Central India. Aboveground biomass samples of grass and soil samples were collected during different seasons based on specified measurement protocol by the state forest department. Aboveground biomass of grass demonstrated a characteristic growth pattern throughout the year, increased and achieved maximum biomass during at the end of rainy season (September), while started decreasing and attained minimum biomass during pre-summer (March) season. Mean aboveground biomass in the study regions was varied from 2.03 (Bandhavgadh National Park) to 5.44 Mg ha-1 (Kanha National Park) with an average...

BRIDGING THE GAP BETWEEN FARMERS AND CONSUMERS: VALUE CREATION AND MEDIATION IN “PASTURE-RAISED BEEF” FOOD NETWORKS AgEcon
Bedoin, Florence; Kristensen, Troels; Noe, Egon.
The aim of this article is to explore how different quality dimensions (safety, aesthetics, ethics and rooted ness) are created in food networks; how these qualities are transferred until the consumers; and how this process is supported by the organisation of the food network. Our postulate is that combining the quality and organisation dimensions and exploring the link between them will provide an interesting perspective for improving the sharing of values in food networks. This framework is applied to five case studies of “pasture-raised beef” food networks in France, representing a diversity of organisations such as public label scheme, cooperate owned brand and direct sell from farmer to consumer. The results highlight the importance of the role of...

Crop Insurance, Disaster Payments and Land Use Change: The Effect of Sodsaver on Incentives for Grassland Conversion AgEcon
Claassen, Roger; Cooper, Joseph C.; Carriazo, Fernando.
Subsidized crop insurance may encourage conversion of native grassland to cropland. The Sodsaver provision of the 2008 farm bill could deny crop insurance on converted land in the Prairie Pothole states for 5 years. Supplemental Revenue Assistance payments, which are linked to crop insurance purchases, could also be withheld. Using representative farms, we estimate that Sodsaver would reduce expected crop revenue by up to 8% and expected net return by up to 20%, while increasing the standard deviation of revenue by as much as 6% of market revenue. Analysis based on elasticities from the literature suggests that Sodsaver would reduce grassland conversion by 9% or less.

Cytisus scoparius (Fam. Fabaceae) in southern Brazil - first step of an invasion process? Anais da ABC (AABC)
Cordero,Rodrigo León; Torchelsen,Fábio P.; Overbeck,Gerhard E.; Anand,Madhur.
The occurrence of Scotch broom Cytisus scoparius (L.) Link (Fabaceae), is reported for the first time in Brazil. The species has been registered in the species-rich Campos Sulinos grasslands, in the Campos de Cima da Serra, and in the Serra do Sudeste. Naturalizing populations were frequently formed in natural habitats near to human settlements, where prevailing land uses and disturbances facilitate dispersal and establishment. The plant is an invasive species that has globally caused significant damage to biodiversity and economic losses. In Brazil, the species has a strong potential for spreading into a wide range of ecosystems. The Atlantic Forest biome and part of the Pampa biome, together known as the Campos Sulinos, represent optimal areas for the...

Dynamics of Forage Production in Pasture-woodlands of the Swiss Jura Mountains under Projected Climate Change Scenarios Ecology and Society
Silvopastoral systems of the Swiss Jura Mountains serve as a traditional source of forage and timber in the subalpine vegetation belt, but their vulnerability to land use and climate change puts their future sustainability at stake. We coupled experimental and modeling approaches to assess the impact of climate change on the pasture-woodland landscape. We drew conclusions on the resistance potential of wooded pastures with different management intensities by sampling along a canopy cover gradient. This gradient spanned from unwooded pastures associated with intensive farming to densely wooded pastures associated with extensive farming. Transplanted mesocosms of these ecosystems placed at warmer and drier conditions provided experimental evidence that...

Ecological Conservation, Cultural Preservation, and a Bridge between: the Journey of Shanshui Conservation Center in the Sanjiangyuan Region, Qinghai-Tibetan Plateau, China Ecology and Society
Shen, Xiaoli; Smithsonian Conservation Biology Institute, National Zoological Park; xlshen.pku@gmail.com; Tan, Jiaxin; Lund University Center for Sustainability Studies, Sweden; jiaxintam@hotmail.com.
The Sanjiangyuan region is located on the Qinghai-Tibetan Plateau in western China and encompasses the headwaters of the Yangtze, Yellow and Mekong rivers. It is also home to 300,000 Tibetan pastoralists. The area is characterized by its significant ecological service, unique culture, and fragile ecosystems, and has undergone a rapid degradation over the past several decades. Traditional Tibetan culture offers alternative knowledge and perspectives that facilitate the environmental conservation throughout the region, but have yet to be recognized or adopted by the Chinese government. Beginning in 2007, the local environmental NGO, Shanshui Conservation Center, has initiated a journey to bridge Tibetan communities with the outside scientific community,...

Effect of high temperature on germination of four legumes from a forest-grassland mosaic in Southern Brazil Biota Neotropica
Silveira,Fernanda Schmidt; Overbeck,Gerhard Ernst.
Passage of a fire can break dormancy of the seeds of many plant species in fire-prone ecosystems. This response to fire is especially well known for the Fabaceae family, but has been poorly studied in Southern Brazil. We collected seeds of four Fabaceae species present in grasslands-forest mosaics of Southern Brazil: Mimosa bimucronata, Desmodium barbatum, Sesbania virgata and Collaea stenophylla. Seeds were exposed to different heat treatments (exposure to 60° and 80 °C for 5 minutes, to 100 °C for 2 minutes, control without heat treatment); not all species were tested in all treatments. After the treatment, the seeds were kept in a germination chamber with a light period of 12/12 hours and temperature of 25 °C. Germinated seeds were counted every 2 days....

Effects of habitat and landscape characteristics on medium and large mammal species richness and composition in northern Uruguay Rev. Bras. Zool.
Andrade-Núñez,María José; Aide,T. Mitchell.
The increasing world population and demand for food and other products has accelerated the conversion of natural habitats into agricultural lands, plantations and urban areas. Changes in habitat and landscape characteristics due to land-use change can have a significant effect on species presence, abundance, and distribution. Multi-scale approaches have been used to determine the proper spatial scales at which species and communities are responding to habitat transformation. In this context, we evaluated medium and large mammal species richness and composition in gallery forest (n = 10), grassland (n = 10), and exotic tree plantation (n = 10) in a region where grasslands have been converted into exotic tree plantations. We quantified mammal species...

Environmental impacts and nutrient recycling on pastures grazed by cattle R. Bras. Zootec.
Vendramini,J.M.B.; Silveira,M.L.A.; Dubeux Jr.,J.C.B.; Sollenberger,L.E..
Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associated with greater nutrient inputs, including those from commercial fertilizers and supplement fed to animals. Excessive loading of nutrients in intensive grazing systems via fertilizer and animal wastes can cause nutrient buildup in the soil and subsequent water quality problems. Surface runoff and leaching of nutrients are the two major process affecting water quality. Nitrogen and P represent major...

Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations Acta Botanica
Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing the dispersal syndromes and fruits types of a plant community may help elucidate plant-animal interactions and colonization strategies of plants. We investigated dispersal syndromes and fruit types in Cerrado formations as a parameter for understanding the evolution of angiosperm reproductive strategies in this mega-diverse tropical biome. To do this we identified and mapped the distribution of different...

Feeding ecology of the maned wolf, Chrysocyon brachyurus (Illiger, 1815) (Mammalia: Canidae), in the Ecological Station of Itirapina, São Paulo state, Brazil Biota Neotropica
Bueno,Adriana de Arruda; Belentani,Sonia Cristina da Silva; Motta-Junior,José Carlos.
The feeding ecology of the maned wolf (Chrysocyon brachyurus) was studied from 1998 to 2002 in the Ecological Station of Itirapina, São Paulo State, southeastern Brazil, including estimates of prey number and biomass consumption. A total of 325 faecal samples was collected in the area. The species is omnivorous, with a broad diet including 68 species or morphospecies of fruits and animals. Armadillos (Dasypodidae), wolf's fruit (Solanum lycocarpum) and small mammals (mostly Clyomys bishopi) were the bulk of the diet, comprising 72.8 % of the total estimated biomass consumed (185,323.4 g). In terms of frequency of occurrence, on the other hand, only small mammals and other miscella-neous fruits yielded 43.4 % of the total occurrences (N = 1,054). Animal...

From forest to cropland and pasture systems: a critical review of soil organic carbon stocks changes in Amazonia. Repositório Alice
FUJISAKI, K.; PERRIN, A.-S.; DESJARDINS, T.; BERNOUX, M.; BALBINO, L. C.; BROSSARD, M..
Abstract - The impact of deforestation on soil organic carbon (SOC) stocks is important in the context of climate change and agricultural soil use. Trends of SOC stock changes after agroecosystem establishment vary according to the spatial scale considered, and factors explaining these trends may differ sometimes according to meta-analyses. We have reviewed the knowledge about changes in SOC stocks in Amazonia after the establishment of pasture or cropland, sought relationships between observed changes and soil, climatic variables and management practices, and synthesized the ?13C measured in pastures. Our dataset consisted of 21 studies mostly synchronic, across 52 sites (Brazil, Colombia, French Guiana, Suriname), totalling 70 forest?agroecosystem...

Fruits and frugivores of the Brazilian Cerrado: ecological and phylogenetic considerations Acta Botanica
Kuhlmann,Marcelo; Ribeiro,José Felipe.
ABSTRACT Knowing the morphological and phylogenetic patterns of fruits of a plant community may elucidate plant-frugivore interactions, and analysis of dispersal syndromes is a practical approach to understanding these mutualisms. We investigated different zoochorous fruits and frugivorous animals among Cerrado formations (forest, savanna and grassland), mapped dispersal syndromes on a Cerrado angiosperm phylogeny and tested for phylogenetic signal. For a core region in Cerrado, we found that, among almost a thousand fruit species and 258 fruit-eating vertebrates, 60% of the fruits had an ornithochorous syndrome and that 70% of the frugivores were birds. Most fruit and frugivorous species (~80%) inhabit forest formations, but many of them also occurred in...
