RD3 mission: Ocean’s biological diversity drives ecosystems and biogeochemical cycles. A deeper knowledge on existing diversity, the associated processes and the reactions to environmental perturbation is needed to project future changes, and to guide sustainable use of biological resources.

These are a few key questions that scientists of RD3 are addressing:

  • How will species interactions and marine communities be reorganized under multiple environmental changes, including invasion pressure and novel pathogens?
  • How will ecosystem biodiversity, functioning and services (for example, productivity, carbon sequestration, nutrient retention) change in response to perturbations and re-organization (due to range shifts /species introductions)? What are the relative contributions of evolutionary change, physiological plasticity and community restructuring to overall ecological response to global change?
  • What are novel marine resources in terms of genetic/genomic resources and marine organism and substances that can be utilized for human application? How can we sustainably use marine resources by understanding the biology of the exploited species in order to minimize effects on population sizes and biodiversity and the affected habitats?

Economic Development Drives World-Wide Overfishing

Kiel researchers have demonstrated: Only sustainable management can prevent the future collapse of wild stocks; an expansion of aquaculture has only a limited effect.
