Restoration challenges and opportunities for increasing landscape connectivity under the new Brazilian Forest Act
(Natureza & Conservacao, 2013-12-01) [Artigo]
Land cover classification of Lago Grande de Curuai floodplain (Amazon, Brazil) using multi-sensor and image fusion techniques
(Acta Amazonica, 2015-06-01) [Artigo]
Given the limitations of different types of remote sensing images, automated land-cover classifications of the Amazon várzea may yield poor accuracy indexes. One way to improve accuracy is through the combination of images ...
Effects of the flooding gradient on tree community diversity in varzea forests of the purus river, central Amazon, Brazil
(Biotropica, 2015-03-01) [Artigo]
Amazonian floodplain forests have remarkable variation in tree diversity and structure related to flood duration. We assessed how floodplain forests respond to the continuum flooding gradient and found that Fisher's values ...
A floristic survey of angiosperm species occurring at three landscapes of the Central Amazon várzea, Brazil
(Check List, 2015-11-10) [Artigo]
The Amazonian floodplains harbor highly diverse wetland forests, with angiosperms adapted to survive extreme floods and droughts. About 14% of the Amazon Basin is covered by floodplains, which are fundamental to river ...
Reconstrução histórica de mudanças na cobertura florestal em várzeas do baixo amazonas utilizando o algoritmo landtrendr
(Acta Amazonica, 2016-01-01) [Artigo]
The Amazon várzeas are an important component of the Amazon biome, but anthropic and climatic impacts have been leading to forest loss and interruption of essential ecosystem functions and services. The objectives of this ...
Species Distribution Modelling: Contrasting presence-only models with plot abundance data
(Scientific Reports, 2018-12-01) [Artigo]
Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) as occurrence data, given their huge numbers and accessibility. ...
Linking plant phenology to conservation biology
(Biological Conservation, 2016-03-01) [Resenha]
Phenology has achieved a prominent position in current scenarios of global change research given its role inmonitoring and predicting the timing of recurrent life cycle events. However, the implications of phenology to ...
The tree species pool of Amazonian wetland forests: Which species can assemble in periodically waterlogged habitats?
(PLoS ONE, 2018-05-01) [Artigo]
We determined the filtered tree species pool of Amazonian wetland forests, based on confirmed occurrence records, to better understand how tree diversity in wetland environments compares to tree diversity in the entire ...
Dual-season and full-polarimetric C band SAR assessment for vegetation mapping in the Amazon várzea wetlands
(Remote Sensing of Environment, 2016-03-01) [Artigo]
This study answered the following questions: 1) Is polarimetric C-band SAR (PolSAR) more efficient than dual-polarization (dual-pol) C-band SAR for mapping várzea floodplain vegetation types, when using images of a single ...
The structuring role of free-floating plants on the fish community in a tropical shallow lake: an experimental approach with natural and artificial plants
(Hydrobiologia, 2016-09-01) [Artigo]
Free-floating plants are important components of aquatic ecosystems in tropical climates, playing a key role in the structure and spatial distribution of fish communities. This study aims at elucidating the potential effects ...
