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.

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...

How can we tell if climate change really affects the population dynamics of a species? "Changes to behaviour, weight or appearance don't always mean population numbers are de- or increasing." NIOO-researcher Martijn van de Pol presents a novel approach to answering the question in the June issue of Ecology Letters.

Massive growth of submerged aquatic plants can be a nuisance, especially in summer. It's up to water managers to limit the inconvenience for swimmers, boats and fishermen in a way that is both responsible and cost-effective. Michiel Verhofstad defended his PhD thesis this week on the 'root' causes of the problem, and how best to tackle it.

The impact of biological clocks on nature and our lives is enormous. Jet lag, mating, bird migration: so much depends on the keeping of time in our bodies and those of other organisms. The latest issue of the world's oldest scientific journal is dedicated entirely to the topic. Featuring researchers from the Netherlands.

The latest UN Environment Frontiers Report has been launched in the Kenyan capital Nairobi.

Most plants that expand their range within their own continent - e.g. under pressure from climate change - won't end up dominating other species. According to NIOO-researcher Rutger Wilschut, possible invasiveness may be predicted by root chemistry not found in native plants.
