1. River damming affects seedling communities of a floodplain forest in the Central Amazon
ABSTRACT The flood pulse of black water rivers in the Amazon basin determines the composition of species along the flood gradient in igapó forests. The Balbina dam, built on the Uatumã River, has altered the flood pulse and caused changes in the floristic composition of adult trees throughout the downstream area. There is a lack of studies on how communiti

2. Restauração passiva em pastagens abandonadas a partir de núcleos de vegetação na Mata Atlântica, Brasil
Resumo Os núcleos de vegetação são estruturas formadas espontaneamente por pequenos agrupamentos de indivíduos arbustivos e arbóreos, que, ao evoluírem em pastagens perturbadas, podem contribuir na sucessão ecológica. Para compreender a evolução dos processos de restauração florestal passiva em ecossistemas tropicais, depois de paralisada a pecu

3. Functional patterns of tree communities in natural Araucaria forests and old monoculture conifer plantations
ABSTRACT A functional perspective of tree communities is helpful for understanding forest dynamics, especially vegetation recovery after other land uses. Knowledge about ecological filters and survival strategies of trees are also important for the restoration of degraded areas. This study aimed to evaluate the functional composition and structure of adult a

4. Tamaulipan thornscrub after fire: an analysis of the composition of species
Resumo Os incêndios florestais são um elemento natural em muitos ecossistemas terrestres, no México uma das principais causas de perda de cobertura vegetal está relacionada a eles, no entanto, nenhuma pesquisa foi realizada nas comunidades de espinheiros de Tamaulipan sobre as estratégias regenerativas pós-fogo de espécies de plantas, portanto, é imp

5. Decline in Giant Tree Numbers: Status Report for Santa Catarina State and Perspectives for Brazil
ABSTRACT Loss of large trees due to indiscriminate timber cutting and opening of new areas for human use is a global problem. Brazil is well known for tree species richness within its extensive forested areas composed of various biomes. Giant trees are “key” to recognize the original forest structure. Decline of their populations in Brazil may be estimat

6. Epífitas vasculares da mata de restinga da Praia do Sul, Ilha Grande, RJ, Brasil
Resumo Plantas epífitas apresentam elevada riqueza e importância ecológica em ecossistemas de Mata Atlântica. O presente estudo visa contribuir para o conhecimento da flora de epífitas vasculares da mata de restinga na Praia do Sul, Ilha Grande, RJ. Demarcamos 52 subparcelas de 100 m2 na Reserva Biológica Estadual da Praia do Sul (RBEPS), onde todas as

7. Composición y estructura del dosel de sombra en sistemas agroforestales con café de tres municipios de Cundinamarca, Colombia
Abstract The composition and structure of the shade canopy in coffee plantations of the municipalities of Tibacuy, Pacho and San Juan de Rioseco, in Cundinamarca, Colombia, were studied. Fifteen (15) farms in each municipality were selected and, in each farm, a coffee plantation (Coffea arabica cv. Castillo), in which it was established a plot of 1000 m2, wh

8. Environmental structure affects taxonomic diversity but not functional structure of understory birds in the southwestern Brazilian Amazon
RESUMO Mudanças nas características ambientais podem influenciar o uso do habitat por aves, afetando o número de indivíduos, a riqueza de espécies e alterando a composição de espécies e estrutura funcional das assembleias. Medidas que avaliam a estrutura funcional de assembléias biológicas constituem uma ferramenta complementar à abordagem taxonô

9. Land use drives change in amazonian tree species
Abstract: The Amazonian rainforest has been subjected to exceptionally high rates of land use change (LUC), primarily for pasture. We present here an analysis of the impact of LUC on trees from studies made in Pará state. LUC results in drastic declines in native species richness, changes species composition and impacts community resilience and ecosystem se

10. Saprobic conidial fungi associated with palm leaf litter in eastern Amazon, Brazil
Abstract: Fungi play an important role in litter decomposition in forest ecosystems and are considered an undersampled group in the Amazon biome. This study aims to describe the composition, richness and frequency of species of conidial fungi associated with palm trees in an area of the Amapá National Forest, State of Amapá, Brazil. Palm leaf litter was co

11. Composition and Functional Diversity of the Urban Flora of Alfenas-MG, Brazil
ABSTRACT Urban tree cover has important environmental and social functions and can act as ecological refuges. The objective of the present study was to investigate the taxonomic and functional diversities of urban plant communities in Alfenas, Minas Gerais State, Brazil. We sampled all trees DBH ≥ 3 cm in eight different urban green areas, recording 1,138

12. 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
