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? -
Impact of nutrients
Nutrient availability in natural ecosystems has increased due to anthropogenic activities like spill-over from agricultural ecosystems. In the Netherlands, this has led to the acidification of natural areas for example. At NIOO, we aim to understand the impact of nutrients on natural systems in more detail, to help to bring back the balance. -
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. -

PhD thesis defence Natalie van Dis: rapid adaptation to climate change in winter moth
On 6 June 2023, Natalie van Dis will defend her PhD thesis titled "Evolution in action: drivers of rapid adaptation to climate change in the winter moth". The ceremony will start at 12:45 h., in the academy building of the University of Groningen.

Dedmer van de Waal has been named Professor by special appointment of Aquatic Functional Ecology at the University of Amsterdam (UvA). -
Seasonal timing of growth and reproduction: ultimate functions and proximate mechanisms
For many species, there is only a short period in the annual cycle in which conditions are suitable for reproduction or growth. -
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. -
Carbon storage in nature
Carbon storage is a hot item. Almost literally, as it is closely linked to climate warming. NIOO researchers discover more and more about the role of the living soil within our planet's carbon cycle. That role is: very influential, invaluable and essential for a sustainable climate policy.
