Similarity analyses indicated greater affinity between the restinga flora from the states of Maranhao and Para than that observed for the states of Maranhao and Piaui, suggesting that the process of species colonization in the former is more likely derived from the Amazon Forest.
We propose a new vegetation model for some areas of the Ice-Age Amazon: a type of seasonally dry tropical forest, with rain forest and montane taxa largely confined to gallery forest.
However, we consider the prediction by the Hadley Center of a near “savannization” of the Amazon forest to be without sufficient scientific basis and unhelpful, because it may even accelerate the deforestation of Amazonia.
These new derivedshould enhance our ability to better understand and model the dynamics of the Amazon forest, with the general procedure for plant functional trait definition described here potentially applicable to many other ecosystems.
O VER 11.5 PERCENT OF THE AMAZON BASIN IS OCCUPIED BY SEASON-ALLY INUNDATED WOODY VEGETATION (Melack & Hess 2010).Seasonally flooded Amazon forests are home to a high diversityof trees (Wittmann et al.
Our results indicate that in the upper Amazon region, primary succession on newly deposited riverine soils is a major mode of forest regeneration.
The principal response of Amazon forest communities to climatic change is in the relative abundance of the more sensitive taxa, particularly in response to interglacial warming.
Our results highlight that the water and energy cycles in the Amazon are driven by not only climate and deforestation but also the past disturbance and changes of forest structure from degradation, suggesting a much broader influence of human land use activities on the tropical ecosystems.
Soil properties in tropical forest (terra firme forest) of the Central Amazon differ substantially along topography, and the biomass and vertical distribution of fine roots may also differ accordingly.
This comparison shows that the Amazon Basin forests were not extensively replaced by savanna vegetation during the glacial period, contradicting the refugia hypothesis.
Together, our data demonstrated the impacts of forest-to-agriculture conversion in the Amazon region and add important information for future research that seeks the development of more sustainable agriculture.
By doing so they have overlooked the important inter‐ and intra‐annual information on vegetation vigour and seasonality within Amazon forest areas that may be discerned with careful analysis of the data.
Results introduce the unique characteristics of the Amazon borderlands and underscore the argument for an alternative means of Amazon integration based on standing forest and biocultural diversity.

The deforestation effect in the Amazon is strong, with reductions in precipitation, evapotranspiration, and cloudiness.
Our results indicate that the Brazilian Amazon now largely consists of two contrasting forest conditions: protected areas with vast undisturbed forests and unprotected forests that are highly fragmented and disturbed landscapes.
We suggest that adaptations of these life-forms drive their responses to soil structure, and thus shape the overall forest physiognomy of Amazonian forest vegetation.
While the short measurement period and lack of spatial replication limit the ability to generalize these results to pasture and forest regions of the Amazon Basin, these results suggest important differences in the magnitude and seasonal variation of NEE and energy partitioning for pasture and transitional tropical forest.
The remaining two-thirds of variations are due to biogeography of the Amazon basin driven by forest composition, structure, and nutrients.
The distinct vegetation formations of the southern Amazon ZOT are markedly more dynamic than core Amazonian forest.
