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. -
Ecosystemen herstellen en verwilderen
Het is een actueel onderwerp en al lang een onderzoeksinteresse van het NIOO: hoe kun je natuur herstellen? Voormalige landbouwgrond krijgt bijvoorbeeld weer een natuurfunctie en gebieden worden met elkaar verbonden. Dit kan ook helpen om de gevolgen van klimaatverandering op te vangen. De laatste jaren komt bovendien steeds meer kennis beschikbaar over ‘rewilding’. Het levert op de lange termijn sterke ecosystemen op met een grotere biodiversiteit, zo blijkt. -
Seasonal timing
Species can adapt over the course of time. As the lives of species are altered by climate change, a different seasonal timing could make them adapt to an early spring, for example. How does this work, and what are the limits to such adaptations? -
How do nutrients and temperature affect cyanobacterial bloom toxicity?
Toxic cyanobacterial blooms threaten freshwater quality, made worse by climate change and eutrophication. The toxicity of these blooms depends not only on cyanobacteria quantity but also on the presence potentially toxin-producing species and genotypes, and their varied toxin production. -

Climate change impacts on harmful algal blooms
Harmful cyanobacterial blooms produce toxins that are a major threat to water quality and human health. Blooms increase with eutrophication and are expected to be amplified by climate change. Yet, we lack a mechanistic understanding on the toxicity of blooms, and their response to the complex interplay of multiple global change factors. Bloom toxicity is determined by a combination of mechanisms acting at different ecological scales, ranging from cyanobacterial biomass accumulation in the ecosystem, to the dominance of toxic species in the community, contribution of toxic genotypes in the population, and the amounts of toxins in cells. -
Developing digital twins to help understand ecosystems
LTER-LIFE aims to study and predict how global change affects ecosystems. It is one of nine projects that have just won funding for setting up and improving large-scale research infrastructure. -
Digitale tweelingen gaan helpen ecosystemen beter te begrijpen
LTER-LIFE, met als hoofdaanvrager Marcel Visser (NIOO-KNAW), is een van de negen projecten die in totaal 140 miljoen euro ontvangen om grootschalige wetenschappelijke infrastructuur op te zetten of te verbeteren. -
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. -
Climate change could make cyanobacteria more toxic
Climate change could result in more toxic cyanobacteria. But what determines their toxicity? Dedmer van de Waal has won a major European grant to find out.
