Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...

River damming affects seedling communities of a floodplain forest in the Centra...

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 communities of seedlings in igapó forests respond to changes in the flood ...

Distribution and Growth of Garcinia brasiliensis Mart. and Hevea spruceana (Ben...

This study assessed the distribution and growth of two tree species in a seasonal mixed-water inundation forest near the city of Manaus, and determined the annual growth rates and ages of trees. The aboveground wood biomass was estimated for each population. Eight plots of 25 × 25 m were established, where all individuals of the species Garcinia brasiliensis and Hevea spruceana with heights ≥ 1.0 m were invento...

The Brazilian freshwater wetscape: Changes in tree community diversity and comp...

Wetlands harbor an important compliment of regional plant diversity, but in many regions data on wetland diversity and composition is still lacking, thus hindering our understanding of the processes that control it. While patterns of broad-scale terrestrial diversity and composition typically correlate with contemporary climate it is not clear to what extent patterns in wetlands are complimentary, or conflictin...

Forest structure and tree species composition of the understory of two central ...

We investigated species composition, distribution, and forest structure of understory trees (≥1m height, <10cm diameter at breast height) in two late-successional várzea forests subject to contrasting levels of inundation within the Mamirauá Sustainable Development Reserve, western Brazilian Amazon, and compared it with the overstory flora at the same study sites. In total, 1486 individuals and 116 woody specie...
