Using food network unfolding to evaluate food-web complexity in terms of biodiversity: theory and applications.

abstract：:Temperature and precipitation explain about half the variation in aboveground net primary production (ANPP) among tropical forest sites, but determinants of remaining variation are poorly understood. Here, we test the hypothesis that the amount of leaf area, and its vertical arrangement, predicts ANPP when other varia...
