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. Species representativeness of Fabaceae in restrictive soils explains the difference in structure of two types of Chaco vegetation
ABSTRACT The distributions of species of Fabaceae are strongly related to the soil. Their presence can alter restrictive conditions and favour the establishment of other species. However, it is still not known how the relationship between species of Fabaceae and edaphic factors interact in structuring woody Chaco vegetation. In this context, we aimed to test

3. 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

4. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

5. Soil microbial C:N:P ratio across physiognomies of Brazilian Cerrado Soil microbial biomass across a gradient of preserved native Cerrado
Abstract: Different physiognomies across the Cerrado could influence the microbial C:N:P ratio in the soil since these physiognomies present different abundance and diversity of plant species. Thus, the aim of this study was to evaluate the microbial C:N:P ratio in soil across three different physiognomies of Cerrado in the Northeast, Brazil, namely campo gr

6. Fitossociologia dos componentes lenhoso e herbáceo em uma área de caatinga no Cariri Paraibano, PB, Brasil
RESUMO Caatinga sensu stricto é a vegetação típica do semiárido brasileiro, adaptada à forte sazonalidade das chuvas e às altas temperaturas. Possui alta riqueza de espécies e alto nível de diversidade beta. O objetivo do estudo foi documentar a flora e fitossociologia das plantas lenhosas e herbáceas de uma área de caatinga. Para isso, amostramos

7. Heterogeneidade ambiental e estrutura da vegetação arbustivo-arbórea em três áreas de Cerrado sentido restrito no Sudoeste goiano
Resumo A variação fitofisionômica do Cerrado brasileiro é intensa e estudos fitossociológicos podem fornecer subsídios sobre quais fatores são responsáveis por essa heterogeneidade ambiental. Nesse sentido, esse estudo teve o objetivo de avaliar a estrutura da vegetação lenhosa de três áreas de cerrado sentido restrito, no município de Jataí -

8. Dynamics of dry tropical forest after three decades of vegetation suppression
ABSTRACT The aim of this study was to analyze the dynamics of the community and shrub-woody individuals in a dry forest in the Brazilian semiarid region after 29 years of vegetation suppression. Individuals with a circumference at 1.30 m above the ground (CBH) ≥ 6 cm were counted and their heights and CBH were measured in 40 permanent plots on three monito

9. Updates on extratropical region climbing plant flora: news regarding a still-neglected diversity
ABSTRACT Most studies concerning climbing plants have focused on lianas, forest ecosystems, and tropical regions. Thus, the majority of existing information is not relevant to all climbing plants (lianas and vines) or all ecoregions of the world (forested and non-forested). We provide an update on floristic and distributional data available for climbing plan

10. FOREST DYNAMICS OF A SUB-XEROPHILOUS VEGETATION FORMATION IN CENTRAL PERU - CHANCHAMAYO VALLEY, PERU
RESUMO Pesquisas sobre os complexos processos de dinâmica da floresta nas florestas montanas e premontanas úmidas (600 a 3000 msnm) são escassas. Este estudo tem como objetivo contribuir com o conhecimento de mudanças na composição florística e dinâmica populacional de espécies lenhosas em um tipo de formação de planta sub-xerofílica imerso nas f

11. Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone
ABSTRACT Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna. Between 2008 and 2013 we evaluated changes in species composition and diversity and in the structure of the woody vegetation of savanna physiognomies in the transition between the Cerrado a

12. Do seedling functional groups reflect ecological strategies of woody plant species in Caatinga?
ABSTRACT It is assumed that morphological traits of seedlings reflect different strategies in response to environmental conditions. The ecological significance of this has been widely documented in rainforests, where habitat structure and species interactions play an important role in community assembly. However, in seasonally dry ecosystems, where environme
