Several recent meta-analyses investigated whether and how biodiversity is changing over time in local communities worldwide. The conflicting results and interpretations from these studies have evoked a controversial discussion. We aim to bring together people and data from both sides of the discussion to clarify points of agreement and disagreement, and to identify data and analyses that could build consensus moving forward. Products of the workshop will include (1) a perspectives paper and (2) a proposal for subsequent workshops or working group meetings to pursue the identified quantitative syntheses.

2nd sDiv meeting: 22.-26.02.2016
Despite substantial evidence of modern environmental degradation, recent data syntheses have sparked controversy over whether and how biodiversity has changed in recent decades. We will jointly advance theoretical and empirical tools for detecting and attributing biodiversity change given available data. Our theoretical synthesis will evaluate methods for estimating and comparing biodiversity across scales and advance conceptual and analytical tools for attributing changes to perturbations. We will identify challenges and solutions for relating modern biodiversity change to conservation and ecosystem function.
