Resolving the carbon (C) balance in the Amazonian forest depends on an improved quantification of production and losses of particulate C from forested landscapes via stream export. The main goal of this work was to quantify litterfall, the lateral movement of litter, and the export of coarse organic particulate matter (>2 mm) in four small watersheds (1–2 ha) under native forest in southern Amazonia near Juruena, Mato Grosso, Brazil (10°25′S, 58°46′W). Mean litterfall production was 11.8 Mg ha… 

Fluvial carbon export from a lowland Amazonian rainforest in relation to atmospheric fluxes

We constructed a whole carbon budget for a catchment in the Western Amazon Basin, combining drainage water analyses with eddy covariance (EC) measured terrestrial CO2 fluxes. As fluvial C export can

Annual litterfall dynamics and nutrient deposition depending on elevation and land use at Mt. Kilimanjaro

Abstract. Litterfall is one of the major pathways connecting above- and below-ground processes. The effects of climate and land-use change on carbon (C) and nutrient inputs by litterfall are poorly

Regional and seasonal patterns of litterfall in tropical South America

Abstract. The production of aboveground soft tissue represents an important share of total net primary production in tropical rain forests. Here we draw from a large number of published and

Temporal dynamics of allochthonous coarse particulate organic matter in a subtropical Atlantic rainforest Brazilian stream

Allochthonous organic matter is a major energy source for headwater stream ecosystems. Therefore, examinations of how energy flows throughout these streams requires knowledge of mechanisms driving

Long-term dynamics of organic matter and elements exported as coarse particulates from two Caribbean montane watersheds

Abstract: In heterotrophic streams the retention and export of coarse particulate organic matter and associated elements are fundamental biogeochemical processes that influence water quality, food

Stream water nutrient and organic carbon exports from tropical headwater catchments at a soil degradation gradient

Carbon and nutrient losses were quantified from four small headwater catchments in western Kenya in the year 2008. They include a forested catchment and three catchments under maize continuously

Water and Chemical Budgets at the Catchment Scale Including Nutrient Exports from Intact Forests and Disturbed Landscapes

The objective of this chapter is to summarize current understanding of the hydrological function and nutrient dynamics of Amazonian forest derived from work in microcatchments and how these processes

Composition and dynamics of allochthonous organic matter inputs and benthic stock in a Brazilian stream

Riparian vegetation provides the nutrient and energy input that maintains the metabolism and biodiversity in tropical headwater streams. In the present study, it was hypothesised that ∼30% of

Land Use Change Influences Ecosystem Function in Headwater Streams of the Lowland Amazon Basin

Intensive agriculture alters headwater streams, but our understanding of its effects is limited in tropical regions where rates of agricultural expansion and intensification are currently greatest.

Particulate Organic Carbon in the Tropical Usumacinta River, Southeast Mexico: Concentration, Flux, and Sources

Particulate organic carbon (POC) derived from inland water plays an important role in the global carbon (C) cycle; however, the POC dynamic in tropical rivers is poorly known. We assessed the POC

Organic carbon fluxes within and streamwater exports from headwater catchments in the southern Amazon

When evaluating forest functions and their responses to climate change, it is important to clarify carbon dynamics in forested basins. Carbon fluxes in litter fall, throughfall, soil solution,

Export of fine particulate organic matter (FPOM) was measured from streams draining Catchments 53, 54, and 55 (C53, C54, and C55) at the Coweeta Hydrologic Laboratory for 5 yr, encompassing the

Nutrient dynamics within amazonian forest ecosystems

A comparative analysis on the rate of fine litterfall and its associated nutrient fluxes was carried out in a mixed forest on Tierra Firme, a tall Amazon Caatinga and a Bana on podsolized sands, indicating common regulating factors in the three forests.

Litter fall, litter stocks and decomposition rates in rainforest and agroforestry sites in central Amazonia

The sustainability of agroforestry systems in Amazonia was assessed from their litter dynamics and decomposition. Litter fall and litter stocks were determined from July 1997 to March 1999 in four

Factors controlling litter input dynamics in streams draining pasture, pine, and native forest catchments

In open pastures the combination of a lack of riparian trees, and the potential litter‐trapping capacity of pasture grasses, severely limits inputs of coarse particulate organic matter to streams.

Removal of riparian vegetation from the banks of the Njoro River would alter the quantity and quality of the litter and reduce CPOM inputs to the river and to a downstream lake with attendant consequences to the energy budget of biocoenoses in the two ecosystems.

It is suggested that the overall carbon budget of rainforests, summed across terrestrial and aquatic environments, appears closer to being in balance than would be inferred from studies of uplands alone.
