The sensitivity of wood production to seasonal and interannual variations in climate in a lowland Amazonian rainforest.

abstract：:In resource-limited savannas, the distribution and abundance of fine roots play an important role in acquiring essential resources and structuring vegetation patterns and dynamics. However, little is known regarding the three-dimensional distribution of fine roots in savanna ecosystems at the landscape scale. We quant...
