  1. The earlier birds pair, the better they fare

    News
    27/02/2021 The breeding season may seem worlds away amidst the recent winter cold, but a research team led by Antica Culina has found that the earlier in the year great tits meet their 'spouse', the more likely they are to breed successfully.

  2. Nocturnal light makes birds change their behaviour

    Press release
    Songbirds change their behaviour and timing when nestboxes are exposed to artificial light at night. "They become light sleepers, literally and metaphorically", says Maaike de Jong (NIOO-KNAW). She successfully defended her thesis on the effects of different colours of light at Wageningen University on Friday. The most surprising effect she's found? Some birds are forced to become more monogamous...

  3. Pharmaceutical residues increasingly disrupt aquatic life

    Press release
    It's a hidden global change: away from the public eye, residues of medicines in water have been causing increasing disruption. They can kill aquatic animals, and play havoc with their food web and reproductive cycle. An international team of researchers led by the NIOO makes an urgent case for better wastewater treatment and biodegradable pharmaceuticals.

  5. Not all lakes are alike: spatial differences key to successful restoration

    Press release
    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.

  7. 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.

  8. Seasonal timing

    Species are able to adapt to changes over time. If climate change is changing their way of life, an adjusted timing may mean that they are still in time for spring. How does this work, and what are the limits to such adaptations in nature?

  10. Seasonal timing of growth and reproduction: ultimate functions and proximate mechanisms

    Project 1993–Present
    For many species, there is only a short period in the annual cycle in which conditions are suitable for reproduction or growth.
