Re-structuring of marine communities exposed to environmental change: a global study on the interactive effects of species and functional richness.

Species richness is the most commonly used but controversial biodiversity metric in studies on aspects of community stability such as structural composition or productivity. The apparent ambiguity of theoretical and experimental findings may in part be due to experimental shortcomings and/or heterog...
