1. Diametric distribution modeling of forest species in arboreal Caatinga vegetation, Brazil
ABSTRACT The distribution modeling in diameter classes is an important indicator of the potential use of a forest community, as well as the projection of future forest production. The objective of this study was to evaluate the diametric structure and to select probabilistic density functions for three woody species in forested arboreal Caatinga vegetation i

2. Population structure, diametric distribution and use of Commiphora leptopholoeos (Mart.) JB Gillett in arboreal Caatinga
ABSTRACT The objective of this work was to characterize the population structure, analyze the spatial distribution pattern and identify the potential use of the Commiphora leptopholoeos in the Contendas do Sincorá National Forest, BA. Thus, three disjoint transects of 40 x 160 m were installed for the phytosociological study and spatial distribution and sub

3. Prediction of diametric and dynamic structures in a semiarid forest (Caatinga) area submitted to Forest Management, Brazil
ABSTRACT Dynamics studies associated with prognosis can support planning actions for the conservation and sustainable use of forest resources. Therefore, the objective of this study was to evaluate the dynamics and predict the diameter structure using the Markov chain model for an area of caatinga forest submitted to different management practices. The study

4. Effect of fire under the soils on the organization of communities of three remnants of Amazonian savannas
ABSTRACT Areas of cerrado (Brazilian savanna) in the Amazon have been poorly studied from the perspective of fire impacts on environmental sustainability, especially with regard to disturbances to soil and vegetation structure. This study aimed to analyze the influence of edaphic variables and fire together on the composition and structure of tree and shrub

6. Estrutura e regeneração de Bertholletia excelsa Bonpl. em castanhais nativos da Amazônia
Resumo O trabalho foi desenvolvido com o objetivo de comparar a estrutura diamétrica e os indicadores de regeneração natural em castanhais nativos e correlacioná-los à fase de desenvolvimento da floresta, à intensidade de coleta de sementes e à exploração madeireira. Os dados foram coletados em 54 hectares nos municípios de Caracaraí - RR e Itaúb

7. FLORÍSTICA, ESTRUTURA E DINÂMICA EM UMA FLORESTA OMBRÓFILA MISTA NO NORTE DO ESTADO DE SANTA CATARINA
The floristic composition, horizontal structure, diametrical distribution and the dynamics (ingrowth, increment, mortality) were evaluated in a remaining of a Ombrophyllous Mixed Forest, located in the National Forest of Três Barras, Três Barras City, Santa Catarina State, within a period of 5 years (2004-2009). In 2004, it were installed and measured 26 p

8. Fitossociologia em ambiente de borda de fragmento de floresta estacional semidecidual
The following work was perfomed in a fragment of a seasonal semidecidual forest in Floresta Nacional de Pacotuba, located in Cachoeiro de Itapemirim, Espírito Santo. In the whole, 39 parcels of fixed area were delimited being 27 (10 x 30 meters) located on the edge and 12 (40 x 50 meters) inside the fragment. In order to get further information concerning c

9. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia / Physical, structural and floristic diversity of forest fragments in the upper basin of the Rio Araguaia
A região da alta bacia do rio Araguaia vem sendo objeto de profundas transformações relacionadas ao processo de ocupação rápida e intensa das terras a partir do final dos anos 70. Atualmente a paisagem nesta região, encontra-se completamente fragmenta. As ilhas de vegetação remanescentes, em sua maioria estão isoladas, cercadas por culturas agríco

10. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

12. DinÃmica estrutural da comunidade arbÃrea de um fragmento de floresta semisecÃdua Ãs margens do Rio Capivari, Lavras/MG / Structural dynamics of arboreal community in a tropical semideciduous forest fragment at Capivari river border in Lavras, Minas Gerais.
The aim of this study was to describe the arboreal community dynamics of a semideciduous seasonal forest fragment Capivari river border in Lavras, Minas Gerais. The forest fragment is known as Capivari forest. The study was divided in three parts: the first is a general description of the approached issues, (chapter 1); the second is about the changes in for
