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...

Floristic, edaphic and structural characteristics of flooded and unflooded forests in the lower Rio Purús region of central Amazonia, Brazil Acta Amazonica
Haugaasen,Torbjørn; Peres,Carlos Augusto.
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...

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,...

Phenology and fruit set comparison of camu-camu (Myrciaria dubia) in a natural population and a plantation in the central Amazon, Brazil. Repositório Alice
FERREIRA, G. A. C.; BARNETT, A. P. A.; KRUG, C..
In this study, phenological observations and fruit yield evaluations were carried out in a natural population of camu-camu in a floodplain habitat and a plantation in terra firme in central Amazonia. Neste estudo, observações fenológicas e avaliação da produtividade de frutos foram realizadas em uma população natural de camu-camu em ambiente inundável e em uma plantação em terra firme, na Amazônia central.
Tipo: Artigo de periódico Palavras-chave: Floodplain forest; Terra firme; Camu-camu; Myrciaria Dubia; Myrtaceae; Flowering; Fruit yield.
