Rosenberg et al.(2019)による衝撃的な論文。北米の鳥類全体では、1970年と比較して約29億羽が減少(38科で約32億羽減少、29科で約2億5000万羽増加)していた。個体数の減少は希少種や絶滅危惧種のみならず、広範囲に生息する普通種でも起きている。 https://t.co/NuMgBYq79J https://t.co/PTRVSeuwFS

The decline of 29% of the 1970 avifauna is an imminent threat. This article urgently attempts to detect the possible reasons for the bird abundance decline, because without their contribution the ecosystem's integrity will severely collapse. #MUevolution21
