Introduction
I am an ecologist, working on belowground processes in tropical ecosystems. My research interest focuses on understanding nutrient cycling and the resource mechanisms of acquisition of plants and microbial communities in scenarios of climate change. Specifically, I'm currently working on plant-root and microbial interaction under elevated CO2 conditions.

The stress‐dominance hypothesis (SDH) predicts that trait variation at the community level increases with the availability of limiting resources, driving spatial and temporal patterns in above‐ground plant functional trait expression. Here, we test the assumption that the SDH also applies to fine roots responding to spatial and temporal fluctuation...
The response of plants to increasing atmospheric CO 2 depends on the ecological context where the plants are found. Several experiments with elevated CO 2 (eCO 2 ) have been done worldwide, but the Amazonian forest understory has been neglected. As the central Amazon is limited by light and phosphorus, understanding how understory responds to eCO 2...
In the Amazon basin, approximately 60% of rainforest thrives on geologically old and highly weathered soils, thus decomposition represents an important mechanism for recycling nutrients from organic matter. Although dead logs and branches constitute up to 14% of the carbon stored in terrestrial ecosystems, woody debris decomposition and mainly the...
In large parts of the Amazon rainforest low soil phosphorus availability may prevent the stimulation of forest growth in response to elevated atmospheric CO 2 (eCO 2). One strategy of plants could be to increase the relative allocation of the extra C belowground to their root systems to enhance nutrient acquisition and alleviate the potential phosp...
Seasonal phenological patterns in the Amazon Forest result from interactions among climate and turnover rates of different plant tissues. Changes in productivity rates and allocation are predicted to occur with climate change, particularly for dynamic tissues such as fine-roots and leaves. Accurate measurements of fine-roots and litterfall dynamics...
Purpose
Large parts of the Amazon rainforest grow on weathered soils depleted in phosphorus and rock-derived cations. We tested the hypothesis that in this ecosystem, fine roots stimulate decomposition and nutrient release from leaf litter biochemically by releasing enzymes, and by exuding labile carbon stimulating microbial decomposers.

Purpose The tropical phosphorus cycle and its relation to soil phosphorus (P) availability are a major uncertainty in projections of forest productivity. In highly weathered soils with low P concentrations, plant and microbial communities depend on abiotic and biotic processes to acquire P. We explored the seasonality and relative importance of dri...
Purpose. The tropical phosphorus-cycle and its impacts on phosphorus (P) availability are a major uncertainty in projections of forest productivity. In highly weathered soils with low P concentrations, plant and microbial communities depend on biological and physical processes to acquire P. We explored the seasonality and relative importance of dri...
Most leaf functional trait studies in the Amazon basin do not consider ontogenetic variations (leaf age), which may influence ecosystem productivity throughout the year. When leaf age is taken into account, it is generally considered discontinuous, and leaves are classified into age categories based on qualitative observations. Here, we quantified...
Soil nutrient availability can strongly affect root traits. In tropical forests, phosphorus (P) is often considered the main limiting nutrient for plants. However, support for the P paradigm is limited, and N and cations might also control tropical forests functioning.
We used a large‐scale experiment to determine how the factorial addition of nitr...
