Project summary:
Evidence across biomes and taxonomic groups reveals that temporal changes in local-scale species diversity are quite small compared to large and widespread changes in community composition. As a result, it is likely the changes in composition, rather than in diversity itself, that will have the greatest impact on how these communities function. This points to a critical need to better understand which (types of) species contribute most to these compositional shifts. New methodological advances now permit quantifying how individual species changes scale up to community change, but such analyses rely on appropriate data. Contemporary resurveys of legacy data offer detailed plot-based community data over decadal time scales and are particularly suitable to address fundamental questions about the causes and consequences of temporal community change and the functional or phylogenetic basis for such change. We will initially analyse a database of 62 single high-quality forest vegetation resurvey studies from temperate forests that span ≥20 years (>3200 vegetation plots). Using hierarchical meta-analytic models and the latest computational approaches, we will test which kind of species consistently decrease, increase or show idiosyncratic patterns within and across studies. Then, capitalizing on the expertise to synthesise compositional changes in for-est vegetation, we will explore ways to synthesise across vegetation change databases, quantifying how communities have changed over time in various vegetation. Our analyses will inform both fundamental ecological theory and applied predictions of vegetation change rele-vant to several initiatives (e.g. IPBES and GeoBON) aiming to quantify and summarize biodiversity changes across the worlds biomes during the Anthropocene.
