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. -
Bewick’s swans choose wintering areas based on the weather
Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers have been able to use long-term GPS data to pinpoint the specific choices that individual swans make. -
Symposium Migratory birds under pressure
On Thursday 7 September 2023 our Animal Ecology department is organising a symposium on migratory birds under pressure, followed by the PhD thesis defence of Kees Schreven the next day. -
PhD Thesis defence Kees Schreven: range expansion in Arctic-breeding geese
On Friday 8 September 2023, our colleague Kees Schreven will defend his PhD thesis "Geese colonising New Land: causes and mechanisms of range expansion in an Arctic-breeding migrant". -
Inaugural lecture by Dedmer van de Waal
Op donderdag 6 juli houdt Dedmer van de Waal zijn oratie als bijzonder hoogleraar Aquatische Functionele Ecologie aan de Universiteit van Amsterdam. -
Forest soil boost for iconic Dutch national park
A major NIOO-supervised experiment is underway in one of the Netherlands most iconic nature areas, with a key role for the soil. -
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.
