Nearly 1000 'citizen scientists' sent in their observations this year on Soil Animal Days 2019. And a surprisingly high number of people tried to do something in return for the vital services these soil creatures provide for us.

Micro-organisms living inside plant roots team up to boost the plant’s growth and tolerance to stress. This research is featured this week in the scientific journal Science.

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.

The conversion of Amazon rainforest for agriculture has led to deforestation and soil degradation. Agroforestry has been suggested as a sustainable alternative, but NIOO's Eiko Kuramae says its impact on the soil needs to be more fully considered.

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.

Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars.
