Consistent response of bird populations to climate change on two continents [Science]

par Frédéric Magné - publié le

Global climate change is a major threat to biodiversity. Large-scale analyses have generally focused on the impacts of climate change on the geographic ranges of species and on phenology, the timing of ecological phenomena. We used long-term monitoring of the abundance of breeding birds across Europe and the United States to produce, for both regions, composite population indices for two groups of species : those for which climate suitability has been either improving or declining since 1980.(...)
