Benthos distribution modelling and its relevance for marine ecosystem management

Extinction and ecosystem function in the marine benthos.

Rapid changes in biodiversity are occurring globally, yet the ecological impacts of diversity loss are poorly understood. Here we use data from marine invertebrate communities to parameterize models that predict how extinctions will affect sediment bioturbation, a process vital to the persistence of aquatic communities. We show that species extinction is generally expected to reduce bioturbatio...

Essays on integrated modelling with applications to marine ecosystem management

After his BSc. in mechanical engineering Jeljer Hoekstra (1962) graduated in applied mathematics at Twente University in 1988. As a draft dodger he stayed shortly at the Dutch meteorological office and somewhat longer at the faculty of philosophy at Twente University. Thereafter, he was employed by the ministry of public works where he learned what silt was and how it could be modelled. Two yea...

Ecological Forecasting: New Tools for Coastal and Marine Ecosystem Management

Policy makers, natural resource managers, regulators, and the public often call on scientists to estimate the potential ecological changes caused by both natural and human-induced stresses, and to determine how those changes will impact people and the environment. To develop accurate forecasts of ecological changes we need to: 1) increase understanding of ecosystem composition, structure, and f...
