Phenology, litterfall, growth, and root biomass in a tidal floodplain forest in the Amazon estuary

Abstract: -(Phenology, litterfall, growth, and root biomass in a tidal floodplain forest in the Amazon estuary). 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 th… Show more

“…As in the present study, Cattanio et al (2004) recorded an increase in the production of the flower fraction of the litter during the dry season in a várzea forest of the Amazon Estuary. The negative correlation with river levels found in both studies (r med =-0.61 here, and r med =-0.65 in the earlier study) reflect a flowering peak between August and October, that is, in the early dry season.…”

“…The differences found in the present study between the island lakes and the sites on the river margin may be related to variations in the response of the different systems to the local characteristics of the flood pulse and hydrological cycle (César, 1991;Cattanio et al, 2004). Even though the forests of the middle Xingu may be distinct from the várzea habitats of the Amazon Estuary, the similar phenological patterns recorded in the present study indicate a standard response to local climatic variation and the intense oscillations in rainfall levels and the related flood pulse.…”

“…It has been postulated that the system is likely to be economically self-sustaining, given the tidal cycles which favor nutrient cycling and thus the long-term productivity of the açaí palms (Cattanio et al, 2004;Muniz-Miret et al, 1996). However, there is a need for detailed studies documenting the responses of multiple taxonomic groups and ecosystem function to açaí production gradients.…”

“…Existem dois padrões básicos para a deposição anual de serapilheira nos ecossistemas brasileiros: o primeiro é caracterizado pela maior deposição na época seca, como ocorre em ecossistemas amazônicos, nas florestas mesófilas e cerrados; o segundo consiste em um aumento na intensidade da deposição de serapilheira na época úmida, típico das florestas atlânticas e restingas (CATTANIO et al, 2004;CIANCIARUSO et al, 2006;ARAÚJO et al, 2006;PIRES et al, 2006). Vários são os fatores que podem estar determinando esses fenômenos.…”
