Dealing with bluegreen algae
Worldwide, excessive nutrient loads in lakes and reservoirs have led to the rapid increase of harmful cyanobacteria. Blooms of these algae block the use of surface water for drinking, irrigation and recreation. Climate change is expected to further increase the frequency, duration, and magnitude of cyanobacterial blooms. Aquatic ecologists from NIOO are busy gaining more detailed insights into cyanobacterial blooms across scales, in future climates and in respect to toxicity. -
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. -
Great tits don't inherit ability to think on their feet
How important is cognitive flexibility for the ability of great tits to adapt to climate change? Krista van den Heuvel did her PhD research at NIOO on this question. -
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. -
Nature research and society
NIOO has a vigorous and long-standing commitment to societal impact. Not only is NIOO housed in a sustainable building designed to translate our ecological principles in terms of architecture and construction, we also have a number of units that are tailor-made for disseminating our ecological knowledge to specific target groups, we have a very active outreach policy, and we actively involve citizens in our research through large-scale citizen-science projects. -
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. -
Climate change
Our climate system is undergoing dramatic changes. We use our expertise to understand the impact on biodiversity, and the capacity of natural systems to help mitigate climate change. -
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. -
Can barnacle geese predict the climate?
The breeding grounds of Arctic migratory birds such as the barnacle goose are changing rapidly due to accelerated warming in the polar regions. They won't be able to keep up with these climatic changes unless they can somehow anticipate them. A team of researchers from the Netherlands Institute of Ecology (NIOO-KNAW) employed computer models to assess the prospects of the geese and their young. The results can be found in the scientific journal Global Change Biology.

Loss of soil carbon due to climate change will be "huge"
55 trillion kilograms: that's how much carbon could be released into the atmosphere from the soil by mid-century if climate change isn't stopped. And all in the form of greenhouse gases such as CO2 and methane. Tom Crowther (NIOO-KNAW) and his team are publishing the results of a worldwide study into the effects of climate change on the soil in the issue of Nature that came out on 1 December.
