American soils are still contaminated with lead

,
For one in four households, the level of lead exposure exceeds the safety threshold set by the Environmental Protection Agency, an Indiana University study has found
Water that does not evaporate first passes through the canopies and carries nutrients to the soil through leaves and branches or along the stems. Photo: Stuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 GenericStuart Rankin CC BY-NC 2.0 DEED Attribution-NonCommercial 2.0 Generic

This is how canopies affect the distribution of soil nutrients

Soil, wildfires and recovery: how much do we know?

,
A U.S. study reviews current knowledge about wildfires and the resilience of ecosystems. Some factors can promote regeneration. Others end up impeding it
Mountain meadows are one of the largest sinks of soil organic carbon in Central Europe. Photo: crash71100 CC0 1.0 DEED CC0 1.0 Universal Public Domain DedicationPhoto: crash71100 CC0 1.0 DEED CC0 1.0 Universal Public Domain Dedication

Mountain meadows are threatened by climate change

,
Rising temperatures drives the loss of humus in mountain meadows and, with it, the release of CO2 into the atmosphere. This is reported in a study by the Technical University of Munich

When restoring ecosystems, biodiversity is the key

,
Brazilian study highlights how the use of increased biodiversity of reintroduced species in restoration areas limits the colonization of invasive species

In biodiversity protection, choosing the right areas halves the costs

,
This is supported by an Australian study: in protecting biodiversity it is better to target smaller but more at-risk areas. The goal is to achieve greater convenience and better results
