ERC provides millions for biodiversity research

This release is available in German.

Leipzig: A group of researchers led by ecological modelling experts Dr Thorsten Wiegand and Dr Andreas Huth and funded by the European Research Council (ERC) has begun work at the Helmholtz Centre for Environmental Research (UFZ) in Leipzig. The researchers will receive over EUR 2 million in research funding from the ERC over the next five years to investigate the composition and dynamics of species-rich communities. Advances in this area are important for biodiversity conservation in connection with climate and land use change, and for calculating carbon balances.

The European Research Council awards the ERC Advanced Grant to provide established, innovative and active researchers an opportunity to pursue frontier research of their choice. The formation of the ERC puts Europe's top researchers into direct open competition for the first time. The first call of the ERC Advanced Grants in life sciences received applications from 766 scientists worldwide. Seventy-eight projects were awarded on the sole criterion of excellence, with only 11 being selected from Germany.

The UFZ had already received a Starting Grant from the ERC in 2008. The group of new researchers led by microbiologist Prof. Lorenz Adrian is researching bacteria that convert chlorinated aromatic hydrocarbons. This makes the UFZ the first Helmholtz centre to have been awarded both a Starting Grant and an Advanced Grant from the ERC.

Over the coming years, the researchers in Thorsten Wiegand and Andreas Huth's team will be investigating why so many species are able to coexist in ecological communities like forests. Their SPATIODIVERSITY project ('Towards a unified spatial theory of biodiversity'), combines high computing power with the latest methods of spatial pattern analysis, individual-based forest simulation models and model selection theory to understand the factors and processes that govern the composition and dynamics of species-rich communities.

The scientific approach is based primarily on information contained in the spatial distribution of species, which has not yet been fully exploited. "To accomplish our goal, we take a radically different approach than previous attempts and adopt a spatially explicit perspective that will allow us to take significant steps towards a 'Unified Spatial Theory of Biodiversity'," explains Thorsten Wiegand. The researchers will be using one of the most extensive data sets currently available in the field of ecology - data from large, long-term research plots in tropical forests that are home to several hundred tree species and over 100,000 individual trees. The trees on these plots are surveyed every five years.

"The project consists of three components," explains Thorsten Wiegand. "In the first stage we will be using the latest spatial pattern analysis techniques to quantify the highly complex spatial structures in tropical forests." "At the same time," Andreas Huth adds, "We will be putting together a raft of individual-based, spatially explicit forest simulation models, ranging from simple 'neutral' models to detailed, process-based simulation models for forests. Our many years of experience of working with forest models such as FORMIND and FORMIX3 will be an advantage here." In the critical third step, the researchers will be applying model selection techniques to discover which of the simulation models best reflect the observed spatial structures. One of the particular challenges of the project is the high level of complexity of the spatial structures and interactions. The extensive analyses can only be successfully tackled in a large project and require a considerable amount of computing power.

Close partners of the project are Prof. Savitri Gunatilleke and Prof. Nimal Gunatilleke (University of Peradeniya, Sri Lanka Plot), and Prof. Sean Thomas (University of Toronto, Malaysia Plot). The project is being supported by Prof. Steven Hubbell, Dr Richard Condit and Dr Stuart Davis, who head the network of research plots in tropical forests organised by the Smithsonian Tropical Research Institute. There are plans to involve more researchers in the project.
