TL;DR: In this article, the authors quantified the yearly change in community composition in response to climate change for 9,490 bird and 2,130 butterfly communities distributed across Europe and found that changes in community compositions are rapid but different between birds and butterflies and equivalent to a 37 and 114 km northward shift in bird and butterfly communities, respectively.

Journal ArticleDOI
Opportunistic citizen science data of animal species produce reliable estimates of distribution trends if analysed with occupancy models
TL;DR: It is investigated whether occupancy models can correct for the observation, reporting and detection biases in opportunistic data, enabling species trends to be monitored for species groups and regions where it is not feasible to collect standardized data on a large scale.
