Pesticides Spark Broad Biodiversity Loss

— Nature

Agricultural pesticides have been linked to widespread invertebrate biodiversity loss in two new research papers.

Pesticide use has sharply reduced the regional biodiversity of stream invertebrates, such as mayflies and dragonflies, in Europe and Australia, finds a study published today in the Proceedings of the National Academy of Sciences1.
