The quantitative relationship between biodiversity, ecosystem functioning and ecosystem services is still poorly understood (Balvanera et al., 2014; 2016). No feature of Earth is more complex, dynamic, and varied than the layer of living organisms that occupy its surfaces and its seas, and no feature is experiencing more dramatic change at the hands of humans than this extraordinary, singularly unique feature of Earth.

Species loss and gain in communities under future climate change: consequences for functional diversity. It is likely that high functional diversity within species induces complementarity effects on decomposition and this may be a potential mechanism leading to diversity effects on the energy flow in detritus‐based food web.
