Centre for Coastal and Estuarine ScienceCCES
Mission March 2008The CCES promotes collaboration between Departments of Microbiology, Animal Physiology, Ecophysiology, Ecology and Environmental Science of the Radboud University Nijmegen (RU), and Spatial Ecology of the Netherlands Institute of Ecology (NIOO), which carry out research on coastal and estuarine systems. CCES aims to increase the visibility of this research for students and third parties. Coastal regions have the highest population densities, and consequently experience high environmental pressure. At the same time, they contain the world’s most productive and diverse ecosystems. The Institute for Water and Wetland Research (IWWR) of the RU is the host of CCES and focuses its research in an integrative approach addressing microbiology, botany and zoology, from molecular biology to ecosystem and landscape level.

Biogeochemical cycles
Carbon cycle• Methane• Carbon dioxide
Nitrogen cycle• Ammonium• Nitrate• Nitrite• Stikstofgas• NOx
Sulfur cycle• Sulfate• Sulfide• VOSC Redox reactions carried out by
bacteria are the driving force in all ecosystems !!
Dep. MicrobiologyCCES

Ecology of tropical coastal systems
Focus is on fishes & invertebrates in fresh, brackish and salt water, in the Netherlands, Europe and the tropics
Dep. Animal Ecology and EcophysiologyCCES
Rotterdam Port:• Biodiversity: challenges and possibilities• Succession and biofouling
Sardinia:• Faunal colonisation hypertrophic lagoons• Food of Sea urchins• Seagrass beds (nursery & zoobenthos)
