2. Influence of Edaphic Attributes on the Distribution of Tree Species in a Riparian Forest in Southern Brazil
ABSTRACT This study aims at identifying the formation of clusters and to evaluate the influence of chemical attributes in the soil on the groups and species in a riparian forest fragment in Campos de Cima da Serra, Rio Grande do Sul (RS). Thirteen plots (10 × 20 m) were demarcated to carry out the study. Forest inventory data were employed in a multivariate

3. Insights from a large-scale inventory in the southern Brazilian Atlantic Forest
ABSTRACT: A key issue in large-area inventories is defining a suitable sampling design and the effort required to obtain reliable estimates of species richness and forest attributes, especially in species-diverse forests. To address this issue, data from 418 systematically distributed 0.4 ha plots were collected. Estimators of nonparametric species richness

4. What explains the variation on the regenerative component dynamics of Araucaria Forests in southern Brazil?
ABSTRACT: The natural regeneration process is essential for forest maintenance since it is critical for establishing new tree individuals. This study aimed to improve the understanding of the regenerative component dynamics of Araucaria Forests in Southern Brazil. We investigated the effects of climate, light, tree component structure and anthropogenic distu

7. Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil
ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. They are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that differ from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest

8. Management of the environmental restoration of degraded areas
The aim of this work was to study ecotechnology for the management of degraded areas originally covered by the Atlantic Rainforest and located at the coordinates 25º31'50''S, 9º09'30''W. The area included 12 islands, each consisting of six jute bags with 20 kg of substrate (cattle manure and soil transposed from forest fragments). In six of these bags, nat

9. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

10. Phytoplankton diversity in the middle Rio Doce lake system of southeastern Brazil
This study presents results of the inventory of algal flora conducted between August 2007 and May 2008 in 18 lakes of the middle Rio Doce lake system, most of which is in the state of Minas Gerais, Brazil. We recorded 481 taxa, increasing the known total phytoplankton diversity of the region (gamma diversity) by 80%. The following classes were represented: Z

12. Amostragem aleatória de ramos como técnica para quantificar a produção de frutos Caryocar brasiliense camp. (caryocaraceae)
The pequi is a species typical of the Cerrado biome, which fruit is an important non-timber forest products - NTFP. However, the extraction of the fruit is done, in general, without management plans or precise information on production. This study was conducted in an area of cerrado sensu stricto, located in the Experimental Ecological Reserve of the Univers
