Última Phenology, litterfall, growth, and root biomass in a tidal floodplain forest in the Amazon estuary Rev. Bras. Bot. Cattanio,José H.; Anderson,Anthony B.; Rombold,John S.; Nepstad,Daniel C.. The dynamics of forests subject to inundation appears to be strongly influenced by the frequency and intensity of natural disturbances such as flooding. In a late successional tidal floodplain forest near the Amazon port of Belém, Brazil, we tested this prediction by measuring seasonal patterns of phenology and litterfall in relation to two key variables: rainfall and tide levels. In addition, we estimated the root biomass and the annual growth of the forest community by measuring stem increments over time. Our results showed high correlations between phenological events (flowering and fruiting) and rainfall and tide levels, while correlations between litterfall and these variations were generally weaker. Contrary to our prediction, root biomass to 1 m... Tipo: Info:eu-repo/semantics/article Palavras-chave: Amazon; Floodplain forest; Litterfall; Phenology; Productivity.

Despite a natural history interest in the early 1900s, relatively little ecological research has been carried out in the Rio Purús basin of central Amazonia, Brazil. Here we describe a new study area in the region of Lago Uauaçú with an emphasis on the climate, forest structure and composition, and soil characteristics between adjacent unflooded (terra firme) and seasonally inundated forests; situated within both the white-water (várzea) and black-water (igapó) drainage systems that dominate the landscape. The climate was found to be typical of that of the central Amazon. Várzea forest soils had high concentrations of nutrients, while terra firme and igapó soils were comparatively nutrient-poor. Terra firme forests were the most floristically diverse... Tipo: Info:eu-repo/semantics/article Palavras-chave: Amazonia; Floodplain forest; Floristic composition; Forest structure; Soil nutrients. Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0044-59672006000100005 Impacts of hydroelectric dams on alluvial riparian plant communities in eastern Brazilian Amazonian Anais da ABC (AABC) FERREIRA,LEANDRO VALLE; CUNHA,DENISE A.; CHAVES,PRISCILLA P.; MATOS,DARLEY C.L.; PAROLIN,PIA. The major rivers of the Amazon River basin and their biota are threatened by the planned construction of large hydroelectric dams that are expected to have strong impacts on floodplain plant communities. The present study presents forest inventories from three floodplain sites colonized by alluvial riparian vegetation in the Tapajós, Xingu and Tocantins River basins in eastern Amazonian. Results indicate that tree species of the highly specialized alluvial riparian vegetation are clearly distinct among the three river basins, although they are not very distinct from each other and environmental constraints are very similar. With only 6 of 74 species occurring in all three inventories, most tree and shrub species are restricted to only one of the rivers,...
