Recent research efforts have resulted in major progress in the theoretical foundations of community ecology, the build-up of vast
databases on species, traits and phylogenetic relationships, and the development of statistical approaches that allow linking ecological
data to ecological theory more directly than was possible before. In spite of these fundamental developments, we still have a very poor
understanding of global biodiversity, both of its current distribution, and of the drivers behind it. The reason for this is a combination of
two factors: extant data are partial and biased, and at the same time the processes underlying biodiversity dynamics are highly complex.
The overarching aim of this proposal is to turn community ecology from a descriptive into a predictive science. In particular, we aim to
achieve a greatly revised understanding of global biodiversity, including its current distribution, the drivers of its dynamics, and how it
can be expected to change due to the ongoing global changes. The research programme covers the entire spectrum from sampling
globally relevant ecological data to developing and applying bioinformatics and statistical methods for generating ecological
knowledge. First, we will generate unprecedented time-series data for fungi, arthropods, birds and mammals, at spatial scales from
100m up to a global scale. Second, we will resolve the challenge of how to reliably identify taxa from massive amounts of new data
originating from automated survey methods, in particular DNA barcoding, autonomous audio recording and camera-trapping. Third, we
will use joint species distribution modelling to turn the new global biodiversity data into a predictive understanding of global
biodiversity dynamics, including the identification of underlying environmental drivers, and the prediction of how global biodiversity
dynamics are expected to respond to environmental change. Fourth, we will use both theoretical and experimental approaches to
critically evaluate the limitations of observational data on species abundances (combined with environmental covariates, species traits,
and phylogenetic relationships) for inferring the processes underlying biodiversity dynamics. From the applied point of view, this
project has the potential to revolutionize biomonitoring by demonstrating that it is feasible to move from indicator approaches to
comprehensive global monitoring of entire species communities.
