Butterfly ranges shift worldwide amid climate change, with most species expanding their reach
A global analysis of range-shift records for 1,758 butterfly species—10% of known butterfly species—found that 80% had expanded their range and that 79% of all recorded range shifts were linked to climate change and extreme weather events. The new study, published in Nature Ecology & Evolution, also reports range contractions for 27% of species, and 22% of species showed a change in elevation. Because many species exhibited multiple types of range shifts, the percentages for expansions, contractions and elevation changes are above 100%.
One research points out that the increase in heat waves and droughts are some of the causes of these movements. The climate crisis is impacting more and more on different species. In this case, 80% of butterfly species have expanded their range due mainly to the impacts of [...] The entry Due to the climate crisis, 80% of butterfly species are moving was first published in Pausa.
