1. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

3. Competition Indexes to Evaluate Tree Growth in a Semi-Deciduous Seasonal Forest
RESUMO A maioria dos estudos que analisa o comportamento da competição arbórea é voltada para plantios homogêneos e equiâneos. Nota-se, portanto, uma carência de informações deste tipo em florestas naturais de elevada biodiversidade. Objetivou-se com este trabalho avaliar a competição em um fragmento de Floresta Estacional Semidecidual, por grupo

4. Soil and leaf nutrient content of tree species support deciduous forests on limestone outcrops as a eutrophic ecosystem
The leaf and soil nutrient status of plants has been used to infer structural and functional aspects at the ecosystem level. Such data are available for tropical and savanna systems growing on poor and acidic soils; however, information for species growing on eutrophic and basic soils is lacking. Deciduous tropical forest is one of the most endangered types

5. 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

6. 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

7. 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

8. Habitat use by terrestrial mammals in fragments of deciduous seasonal forest / Uso de hábitat de mamíferos terrestres em fragmentos de floresta estacional decidual
The constant environmental degradation, in special the habitat fragmentation, has leading to alterations in mammal populations around de world. Into the Campos de Instrução de Santa Maria (CISM), Santa Maria, State of Rio Grande do Sul/Brazil, it is not different, since the human colonization has led to habitat loss and fragmentation. In this region the Ca

9. Floristic, phytossociology and edaphic caracters of two deciduous dry forests within Triângulo Mineiro region / Florística, fitossociologia e caracteres edáficos de duas florestas estacionais deciduais no Triângulo Mineiro
Deciduous dry forests are characterized by both seasonal climate and great leaf fall of the arboreus elements. They are distributed throughout tropical regions and within Triângulo Mineiro region they can be found in uphill turned around rivers. Currently, those forests are in a critical conservation status. Deciduous dry forests are the most threatened of

11. As florestas montanas da Reserva Florestal do Morro Grande, Cotia (São Paulo, Brasil) / The montane forests of the Morro Grande Forest Reserve, Cotia (São Paulo State, Brazil)
The Morro Grande Forest Reserve is located in the municipality of Cotia, state of São Paulo, Brazil, in the Ibiúna Plateau, on the borders of the Paulistano Plateau (ca. 23o35 -50 S and 46o50 - 47ºWG). The Reserve protects an area of 10,000 ha of forest formed by patches of varying successional stages, in an altitude that ranges between 850-1.050 masl. Th

12. A vegetação no município de Ventania (Paraná, Brasil)
The municipality of Ventania is located in the central part of the Tibagi river basin which has mixed forests with typical components of the semi-deciduous seasonal forest and the mixed rain forest, besides the riverine areas, the fields and savannah. The mixed rain forest parts located in altitudes above 1000-1200m are called upper montane forests. The alti
