Data from: Quantifying interspecific and intraspecific diversity effects on ecosystem functioning

<p>Rapid environmental changes result in massive biodiversity loss with detrimental consequences for the functioning of ecosystems. Recent studies suggest that intraspecific diversity can contribute to ecosystem functioning to an extent comparable to contributions of interspecific diversity. Knowledge of the relative importance of these two sources of biodiversity is essential for predicting ecosystem consequences of biodiversity loss and will aid prioritization of conservation targets and implementation of management measures. However, our quantitative insights into how interspecific and intraspecific biodiversity loss affects ecosystem functioning, and how the effects of these two sources of biodiversity loss on ecosystem functioning can be compared are still very limited. To facilitate this goal, we extend the interspecific Price partitioning method originally introduced by J. Fox in 2006, previously used to quantify species loss and gain effects on ecosystem functioning, to also account for the effects of intraspecific diversity loss and gain on ecosystem function. Using this extended version can provide the quantitative information required for answering research questions addressing correlations between interspecific and intraspecific diversity effects on ecosystem function, identifying interspecific and intraspecific groups with large effects, and assessing whether intraspecific diversity can compensate for losses in interspecific diversity. Applying this method to carefully designed experiments will provide additional insights into how biodiversity loss at different ecological levels contributes to and changes ecosystem functioning.</p>
