Lower the water level in a marsh temporarily and you get a more resilient, healthy and biodiverse ecosystem in return. That is the advice of ecologist Kerstin Bouma and her colleagues at the Netherlands Institute of Ecology (NIOO-KNAW). An extraordinary opportunity presented itself in the Oostvaardersplassen to find out how this works. She defended her PhD on that research in the mud and among the reeds on Friday 4 April.

Ecohydrologist Stefan Dekker has been named the new director of the Netherlands Institute of Ecology (NIOO-KNAW), the Royal Netherlands Academy of Arts and Sciences' national institute for ecological research, effective 15 June 2025. Dekker is currently serving as professor of Global Ecohydrology and Sustainability at Utrecht University and as research director of the Copernicus Institute of Sustainable Development. He will succeed NIOO’s interim director Wim van der Putten.

West Greenland is home to tens of thousands of blue lakes that provide residents drinking water and sequester carbon from the atmosphere. Yet after two months of record heat and precipitation in fall 2022, an estimated 7,500 lakes turned brown, began emitting carbon and decreased in water quality, according to a new study NIOO is involved in.

City dandelions grow better in hot summers and flower better after mild winters than their rural counterparts. This is according to research by the Netherlands Institute of Ecology (NIOO-KNAW) that compared dandelions from the centre of Amsterdam with plants outside the city. These experiments - published in the December edition of Evolution Letters - show that dandelions evolved to adapt to urban heat. Such knowledge is essential for sustainable urban planning.

Young, naïve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic ‘displacement’ experiment and by adding new data, a team of researchers at the Netherlands Institute of Ecology (NIOO-KNAW) and the Swiss Ornithological Institute (Vogelwarte Sempach) have settled a long-lasting debate. Their findings are now published in the scientific journal Biology Letters.

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.

How much earlier can great tits lay their eggs to keep up with climate change? A team from the Netherlands Institute of Ecology (NIOO-KNAW) took a sneak peek into the birds’ future.

An international research team led by the Netherlands Institute of Ecology (NIOO-KNAW) is to search for invisible life in the Galápagos Islands.

A new study comparing 46 field experiments in 17 countries across four continents shows that areas in need of nature restoration benefit from soil transplantation. The results were collected by an international team led by Jasper Wubs (NIOO-KNAW).

An international team of scientists has examined the long-term effects of fireworks on wild birds.

‘If no action is taken to better understand and reduce the impact of climate change on insects, we will drastically limit our chances of a sustainable future with healthy ecosystems.’ This warning in a very topical paper in Ecological Monographs comes from 70 scientists from 19 countries around the world. But, they also provide ways to help insects in a warming world complete with management strategies.

Between 23 September and 5 October, we're asking you to go on a safari in your own garden, do the survey, and spread the word to as many people as possible.
