Short description

Biodiversity change is one of the biggest challenges facing mankind. To understand the complex patterns of this change, ecologists are dependent on the availability of monitoring data and the development of statistical tools to analyse these data. For most organisms, the available data that can inform on past trends are a heterogeneous mix of data types of varying accessibility.
In the Biodiversity Change working group, we compile community datasets from heterogeneous data sources from agencies, natural history societies and citizen science projects on various taxa and develop and apply statistical methods to analyze them. Our questions are focused on species long-term population trends and community turnover; the geographic patterns of change and links to environmental variation, and the predictive ability of response and effect traits, and species co-occurrence patterns. Moreover, we use simulation models to assess how much (and what type of) data are needed to detect population and community changes over time as well as the ability of different analytical approaches to account for the different sorts of biases within unstructured biodiversity data.

Methodological focus

• Occupancy-detection models
• Point pattern models
• Frescalo models
• Hierarchical (Bayesian) mixed models with spatio-temporal autocorrelation

sMon is a Synthesis Project of the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig. We aim at combining and harmonizing exemplary datasets of different taxa and habitats and to evaluate the potentials and limits for analyzing changes in the state of biodiversity in Germany. Based on these insights, we will derive perspective for future biodiversity monitoring programs in Germany.

Aims and scope

  • Screening, harmonizing and integrating heterogeneous time series data from different sources and from exemplary species groups
  • Development of statistical methods to derive statistically sound trends for species from these taxa based on this heterogeneous data
  • Assisting in the identification of statistical cornerstones for the collection of biodiversity data within an efficient future biodiversity monitoring scheme in Germany
