1. Grassland vegetation sampling - a practical guide for sampling and data analysis
ABSTRACT Grassland and savanna ecosystems are the original vegetation types of more than 30% of the Brazilian territory, but conservation and training of future professionals has largely focused on forests. In fact, no standard protocols exist for sampling grassland vegetation for environmental planning or licensing. Neglecting non-forest ecosystems may have

2. Flora and Vegetation in Different Physiognomies of a Mussununga in Southeastern Brazil
ABSTRACT Mussununga is an understudied ecosystem within the Atlantic Forest domain, in sandy spodosol lowlands from Bahia to Espírito Santo. Its physiognomy varies from grassland to forest, with a transitional savannic area. We evaluated the life-form spectra differences between the grassland and savanna Mussunungas and its relationship with the depth of a

3. First standardized inventory of ants (Hymenoptera: Formicidae) in the natural grasslands of Paraná: New records for Southern Brazil
Abstract Despite the large number of studies investigating ant diversity in Brazilian biomes, no ant-related studies have been carried out in Campos Gerais, a grassland physiognomy in Paraná state. The present study is the first inventory of the ant fauna in one of the few conservation units protecting the Campos Gerais landscape, the Guartelá State Park (

4. Temporal profiles of vegetation indices for characterizing grazing intensity on natural grasslands in Pampa biome
ABSTRACT The Pampa biome is an important ecosystem in Brazil that is highly relevant to livestock production. The objective of this study was to analyze the potential use of vegetation indices to discriminate grazing intensities on natural grasslands in the Pampa biome. Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation In

5. Spider species composition in the tree-shrub strata of riparian forests and its microhabitats in southern Brazil
ABSTRACT The composition of the spider fauna of riparian forests is insufficiently known. These forests, adjacent to both aquatic and terrestrial environments, are recognised as having important ecosystem functions. We compare the composition of spider assemblages of four riparian forests in different drainage basins, along with their microhabitats (edges an

6. DINÂMICA DO FÓSFORO EM ECOSSISTEMA DE PASTAGEM NATURAL SUBMETIDO À APLICAÇÃO DE FONTES DE FOSFATO / PHOSPHORUS DYNAMICS IN NATURAL GRASSLAND ECOSYSTEM SUBMITTED TO APPLICATION OF PHOSPHATE SOURCES
O conhecimento da dinâmica do fósforo nos ecossistemas campestres pode ser importante para a prescrição das alterações provocadas pela adição de diferentes fontes de fertilizantes fosfatados sobre as formas de P no solo, na produção de matéria seca e na composição botânica das pastagens naturais. O objetivo do presente trabalho foi avaliar a in

7. Fluxos hídricos na microbacia do córrego do Queixada no município de Jataí / Water flows in the stream watershed queixada in the city of Jataí (Go)
The diagnosis of hydrological flow and the rainfall interception by vegetation is justified by the need for knowing the influence of these elements in river basins, where weeds and appropriate use of land are responsible for maintaining the quality of the slopes, avoiding erosion, soil loss, silting of waterways and induces the maintenance of groundwater res

9. Soil seed bank variation patterns according to environmental factors in a natural grassland
O trabalho objetivou determinar o banco de sementes presente em uma área excluída de campo natural localizado na região sul do Brasil e sua correspondência com fatores abióticos que possuem influência no desenvolvimento e distribuição da vegetação presente. Foram identificadas 122 espécies, sendo a maioria perenes. Observou-se uma nítida separaç

10. Relações solo-vegetação no Parque Nacional da Serra do Cipó, Espinhaço Meridional, Minas Gerais / Soil vegetation relationships in the National Park Serra do Cipó, in Espinhaço Meridional, Minas Gerais
The region of Serra do Rio Cipó, in the southern part of the Serra do Espinhaço, comprises large areas of Cerrado, Atlantic forest, forest islands and one of the richest high-altitude rocky vegetation in Brazil. The ecotonal character between the Cerrado and Atlantic Forest biomes, described in many studies of regional flora and fauna, is one of the factor

11. Albedo em cerrado sensu stricto como resposta à variação climática e biológica: conexões com índice de vegetação, estoques de carbono e fluxos de CO2 / Albedo in cerrado sensu stricto as response to climatic and bilogical variation: connections with vegetation index, carbon stocks and fluxes of CO2
In this work we analyze the climatic variability influence over a woodland savannah ecosystem at Gleba Pe de Gigante, Santa Rita do Passa Quatro, SP, during the 2001-2007 period. The data collected for this analysis are from a micrometeorological tower located at Vassununga State Park, which was installed under the thematic project called Biosphere- Atmosphe

12. Redundância funcional em comunidades campestres / Functional redundancy in grassland plant communities
Os campos do Rio Grande do Sul apresentam grande biodiversidade, beleza cênica e um importante recurso para a economia do estado, cuja principal atividade é a pecuária. O manejo inadequado do campo traz conseqüências graves para a diversidade e sustentabilidade desse ecossistema através da perda de espécies promovida pelo pastejo excessivo. Entretanto
