  1. Under the bird ring's spell

    News
    Ringing of wild birds has become indispensable as a research method to track individual birds. Since 1911, some 16 million birds have been fitted with a metal ring in the Netherlands. What has that brought in terms of knowledge, protection and policy? And what do new tracking techniques add? We dive into the world of meadow birds, goose visits and infectious diseases.

  3. Less intensive works best for agricultural soil

    Press release
    The less intensively you manage the soil, the better the soil can function. Such as not ploughing as often or using more grass-clover mixtures as cover crops. These are the conclusions from a research team led by the Netherlands Institute of Ecology (NIOO-KNAW). Surprisingly, it applies to both conventional and organic farming. These important insights for making agriculture more sustainable are published in the scientific journal Science today. ‘It offers clear evidence to help farmers manage soils better.’

  4. Up and down the marshes

    Press release
    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.

  5. Ancient blue-green algae bloom more and more

    News
    Every summer there they are again, blue-green algae. Why are they a problem, are they getting worse with climate change and what can we do about them? These are questions that the Netherlands Institute of Ecology (NIOO-KNAW) has over the past few years been and still is seeking answers to. The research has provided new insights into fundamental processes, from the cellular level to large-scale changes in lakes and ponds. This allows better assessment of risks and possible development of new control methods.

  9. Five years as a director: a retrospective and a peek at the future

    News
    Until October last year, Geert de Snoo was at the helm of the Netherlands Institute of Ecology (NIOO-KNAW). A few months later, we look back with him on five years of directorship and talk about his new role as director of research policy at the Royal Netherlands Academy of Arts and Sciences (KNAW).

  10. Do methane cycling microbes keep Arctic lakes in check?

    News
    How do microbes influence the methane release in the arctics? And how will climate change influence these microorganisms? These questions and more are what a new research project led by Suzanne McGowan of the Netherlands Institute of Ecology (NIOO-KNAW) will try to answer.

  11. Extreme climate pushed thousands of lakes in West Greenland 'across a tipping point'

    Press release
    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.

  12. Dandelion evolves along with hot city

    Press release
    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.
