Collation of a century of soil invertebrate abundance data suggests long-term declines in earthworms but not tipulids

This study identifies what could be a previously undetected biodiversity decline that potentially represents a significant conservation and economic issue in the UK.

A review of the impacts of air pollution on terrestrial birds

A review paper by BTO considers 203 studies of the effects of air pollution on 231 bird species. Of these studies, 82% document at least one negative effect associated with increasing levels of pollution. The review also highlights biases towards particular study species, especially Great Tit and Pied Flycatcher, and also towards particular geographical regions (Western Europe) and pollutants (heavy metals). The paper proposes research approaches that could help to provide a fuller understanding of how birds are impacted by air pollution.
