Abstract
The increasing risk of irreversible ecological transformation under global warming has boosted the need to understand the capacity of organisms to adapt to this change. Here, using a resurvey method of populations of the European fly Drosophila subobscura, we show that a known evolutionary response to global warming has accelerated in the past 20 years, in step with regional warming. This genetic response has come entirely by resorting pre-existing variation—and not from novel inversions—for tolerance to high temperature. Temperate populations are predicted to converge to the typical Mediterranean chromosomal composition by the mid-2050s, at which point this classic example of steep genetic cline will have vanished. Our results suggest that species with broad geographic ranges, large population sizes and high genetic diversity may have the evolutionary potential to cope with climate change. The authors resurvey data from the present, late 1960s and late 1990s to understand the evolution of European Drosophila fly populations. They show that genetic changes in temperate regions have accelerated in line with warming and come from pre-existing rather than new variation.
期刊介绍:
Nature Climate Change is dedicated to addressing the scientific challenge of understanding Earth's changing climate and its societal implications. As a monthly journal, it publishes significant and cutting-edge research on the nature, causes, and impacts of global climate change, as well as its implications for the economy, policy, and the world at large.
The journal publishes original research spanning the natural and social sciences, synthesizing interdisciplinary research to provide a comprehensive understanding of climate change. It upholds the high standards set by all Nature-branded journals, ensuring top-tier original research through a fair and rigorous review process, broad readership access, high standards of copy editing and production, rapid publication, and independence from academic societies and other vested interests.
Nature Climate Change serves as a platform for discussion among experts, publishing opinion, analysis, and review articles. It also features Research Highlights to highlight important developments in the field and original reporting from renowned science journalists in the form of feature articles.
Topics covered in the journal include adaptation, atmospheric science, ecology, economics, energy, impacts and vulnerability, mitigation, oceanography, policy, sociology, and sustainability, among others.
