13. Responses of riffle beetle assemblages to deforestation in a semi-deciduous Atlantic Forest remnant
Abstract Deforestation affects freshwater assemblages since aquatic organisms are dependent on the structure of the riparian vegetation. To investigate the responses of riffle beetles (Elmidae) to deforestation, this study assessed the structure of riffle beetle assemblages found in streams running through a large and well-preserved semi-deciduous Atlantic F

14. Litterfall: A Bio-indicator for Edge Effect in a Semi-deciduous Seasonal Forest
ABSTRACT This study aimed to evaluate the use of litterfall as an indicator of fragmentation in a Semi-deciduous Seasonal Forest in Além Paraíba, MG, Brazil. Litterfall was collected monthly for one year in conical collectors (0.25 m2 of surface), located at seven distances from the forest edge: 10, 30, 60, 100, 160, 250 and 350 m. The litterfall was drie

15. Floristic-functional variation of tree component along an altitudinal gradient in araucaria forest areas, in Southern Brazil
ABSTRACT We aimed to investigate the taxonomic and functional variations of tree component of Araucaria Forest (AF) areas located along an altitudinal gradient (700, 900 and 1,600 m asl), in the southern region of Brazil. The functional traits determined were leaf area, specific leaf area, wood density, maximum potential height and dispersal syndromes and de

16. Late Holocene Vegetation History and Early Evidence of Araucaria angustifolia in Caçapava do Sul in the Lowland Region of Rio Grande do Sul State, Southern Brazil
Little is known about the southernmost occurrence of small areas with Araucaria angustifolia populations in Caçapava do Sul in low elevated areas of Rio Grande do Sul State, about 130 km to the south of to the highlands of southern Brazil where the main distribution of Araucaria is found. This occurrence is about 130 km further south to the main area of Ara

17. Consequences of suppressing natural vegetation in drainage areas for freshwater ecosystem conservation: considerations on the new "Brazilian forest code"
The input of particulate and dissolved organic matter (POM and DOM, respectively) from terrestrial ecosystem drainage basins is an important energy and nutrient source in limnic food chains. Studies indicated that semi-deciduous seasonal forests located in drainage areas in Brazil have the potential to produce 7.5 - 10.3 Mg ha−1/year of POM. The global inc

18. Gradientes edáficos e sua relação com as fitofisionomias do semi-árido meridional brasileiro / Edaphic gradients and their relationship with the vegetation types of semi-arid southern Brazil
The semi-arid region in Brazil represents a significant territorial extension, where the climate is markedly seasonal, with low rainfall, high evapotranspiration and higher temperatures. Its southern portion comprises the northern boundary between the states of Minas Gerais and Bahia. This region is dominated by dry forest vegetation type, however, different

19. Análise espacial de remanescentes florestais como subsídio para o estabelecimento de unidades de conservação
O quadro atual de fragmentação dos remanescentes de vegetação natural no interior de São Paulo gera a necessidade de ações urgentes para a conservação. A priorização de áreas é o primeiro passo para a elaboração de estratégias para conservação da biodiversidade, pois permite o direcionamento dos esforços e recursos para conservação e sub

20. Hydro-physical characterization of soils under tropical semi-deciduous forest
The study of the hydro-physical behavior in soils using toposequences is of great importance for better understanding the soil, water and vegetation relationships. This study aims to assess the hydro-physical and morphological characterization of soil from a toposequence in Galia, state of São Paulo, Brazil). The plot covers an area of 10.24 ha (320 × 320

This work contributes to a project \"Flora da Serra do Cipó, Minas Gerais, Brazil, being a survey and a taxonomic study of the family Sapindaceae in that area. The family Sapindaceae includes about 1756 species and 136 genera, predominantly pantropical. The family is characterized by its pinnately compound leaves, flowers with a extraestaminal nectar disk,

22. Drought resistance in seedlings tree species of semideciduous tropical forest / Resistência à seca em plântulas de espécies arbóreas da floresta estacional semidecídua
The rainfall is high in tropical forests, but there is great variation in water availability to plants. On a local scale, this availability may vary depending on the location of individuals in gaps, their position in the landscape and soil composition. On a regional scale, variations related to the volume and distribution of rainfall, coupled with seasonal c

23. Population ecology of small rodents and marsupials in a semi-deciduous tropical forest of the southeast Pantanal, Brazil
The Pantanal is a South American biome characterized by extensive plains and stark environmental seasonality. Several habitats are subject to annual flooding, forcing small mammal species to aggregate in dry forest patches, which most likely influences their population dynamics and life history strategies. In order to investigate the seasonal influence on th

24. Micorriza arbuscular: um bioindicador da fertilidade dos solos e da distribuição de árvores no bioma cerrado.
RESUMO: A grande variedade de fitofisionomias existentes no Bioma Cerrado tem sido associada a diferentes fatores ambientais como clima, relevo, geologia, entre outros. O fator solo exerce influência fundamental nessa diversidade ambiental. As suas características químicas, físico-hídricas e biológicas formam um complexo de inter-relações, muitas vez
