Earthworms winners of humid 2023 & Leeuwarden bags the title Soil Animal City of the Year
Spring has started in the Netherlands, and that means our soil life is very active again. How much do we know of the creatures living under our feet? That is where the citizen science project of the Soil Animal Days comes in. What did the results of 2023 show us? Earthworms like wet weather and managed to retain their position in the national soil animals Top 3: they were spotted in 87% of gardens. And in Leeuwarden, people searched for soil animals with such enthusiasm and a clear focus on the importance of soil animals that the Frisian capital may proudly call itself Soil Animal City of the Year. -
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? -
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. -
Omgaan met blauwalgen
Wereldwijd heeft een grote aanvoer van voedingsstoffen in meren en andere wateren geleid tot overmatige groei van blauwalgen. De 'bloei' van deze algen kan ervoor zorgen dat oppervlaktewater niet meer te gebruiken is als drinkwater, voor irrigatie en recreatie. Klimaatverandering vergroot naar verwachting de frequentie, duur en intensiteit van de algenbloei. Aquatisch ecologen van het NIOO zijn op zoek naar meer kennis over de bloei van blauwalgen in het huidige en toekomstige klimaat, en hun giftigheid. -
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. -

Regenwormen zijn winnaars van vochtig 2023 & Leeuwarden verovert titel Bodemdierenstad van het jaar
Op 5 december is het óók Wereldbodemdag. Ter ere daarvan maakt de organisatie van de Bodemdierendagen de scores van de Nederlandse bodemdieren in 2023 bekend. De regenwormen houden wel van nat weer en weten hun toppositie in de Bodemdieren Top 3 vast te houden: ze zijn in 87% van de tuinen gespot. En in Leeuwarden is met zoveel enthousiasme en aandacht voor hun belang naar bodemdieren gezocht, dat de Friese hoofdstad ditmaal de eretitel Bodemdierenstad van het Jaar mag voeren. -
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. -
National Soil Animal Days 2024
Every year around World Animal Day, we go on safari in our own gardens looking for the important but often overlooked soil animals. This year marks the 10th edition of the Soil Animal Days. -
Bodemdierendagen 2024
Ieder jaar gaan we rond Dierendag op safari in eigen tuin, op zoek naar die belangrijke maar vaak vergeten bodemdieren. In 2024 is het tijd voor de 10e editie!
