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.

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.

The extinction of large herbivores such as mammoths could explain massive prehistoric changes in vegetation and landscape structure, with major implications for our understanding of present-day ecosystems. Modern and paleo-ecologists joined forces in an international study led by the Netherlands Institute of Ecology (NIOO-KNAW). The results are being published online by PNAS this week.

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.
