Restoring and rewilding ecosystems
It is a topical issue and has long been a research interest of NIOO: how do you restore nature? For example, former farmland can be made more suitable for nature again, and areas connected to each other. This approach could also help to mitigate the consequences of climate change. Furthermore, a growing amount of knowledge about rewilding has become available in recent years. It has become clear that, in the long run, rewilding yields strong ecosystems with more biodiversity. -
The pandemic and the 'anthropause': European lessons for water managers
The COVID-19 pandemic presented scientists with a unique opportunity to study the effects of an ‘anthropause’: an abrupt reduction of, and/or alteration in, human activities. -
Marker Wadden
The Marker Wadden is a newly constructed archipelago in lake Markermeer, which aims to improve the lake’s degrading food web by stimulating primary productivity. The archipelago consists of five islands that add a currently missing habitat type to the lake: shallow, sheltered waters with high nutrient availability and gradual land-water transitions. -
Nuisance growth of aquatic plants: to mow or not to mow?
Massive growth of submerged aquatic plants can be a nuisance, especially in summer. It's up to water managers to limit the inconvenience for swimmers, boats and fishermen in a way that is both responsible and cost-effective. Michiel Verhofstad defended his PhD thesis this week on the 'root' causes of the problem, and how best to tackle it. -
Pharmaceutical residues increasingly disrupt aquatic life
It's a hidden global change: away from the public eye, residues of medicines in water have been causing increasing disruption. They can kill aquatic animals, and play havoc with their food web and reproductive cycle. An international team of researchers led by the NIOO makes an urgent case for better wastewater treatment and biodegradable pharmaceuticals. -
Research among mallards proves: migratory birds don't import bird flu but contract it here
Migratory birds are often blamed for spreading avian influenza. But new research proves for a specific flu type that instead of importing the virus into the Netherlands, migratory mallards actually contract it here. NIOO-researcher Jacintha van Dijk defends her thesis on the topic at Utrecht University on Wednesday.
