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. -
A living, breathing building
As sustainable as possible, in as many respects as possible: that was the imperative when the Netherlands Institute of Ecology (NIOO-KNAW) commissioned a new building. And we have done it! -
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. -
NIOO Theme Climate change
We are in the midst of a climate crisis. Our climate system is undergoing a dramatic number of changes, many of which can be attributed to anthropogenic influences, including greenhouse gas emission-induced changes to global surface temperatures, precipitation, glacier mass loss, sea levels, salt intrusion, and ocean heat content. -
Not all lakes are alike: spatial differences key to successful restoration
Degradation of lakes is a worldwide problem, with symptoms including toxic algae blooms. Restoration is possible, but takes a lot of time and effort. To determine what approach is most effective, spatial differences between lakes must be considered. -
Concern over 'red tide' in Dutch coastal waters
Climate change could lead to an increased occurrence of harmful algal blooms in Dutch coastal waters in the future. NIOO-researchers Karen Brandenburg and Dedmer van de Waal have been studying the dense blooms formed by tiny organisms known as dinoflagellates. -
The world's most spoken language is...Terpene
If you’re small, smells are a good way to stand out. A team of researchers led by the Netherlands Institute of Ecology (NIOO-KNAW) has demonstrated for the first time that two different types of micro-organisms – bacteria and fungi – use fragrances, known as terpenes, to hold conversations. And that’s not all. “We actually believe that terpenes are the most popular chemical medium on our planet to communicate through.”
