In nature, plants cannot grow without soil biota such as fungi and bacteria. Successful plants are able to harness positive, growth-promoting soil organisms while avoiding the negative effects of others. Which plant traits can predict these interactions, or the success of a plant? Researchers and plant breeders would like to know. In a paper in the Journal of Ecology of August 24, a team from the Netherlands Institute of Ecology (NIOO-KNAW), Wageningen University and the Universität Leipzig tested exactly this and found thick roots to be a leading trait.

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.

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.
