Butterflies Responses To Warmer Temperatures Could Compromise Their Ability To Adapt To Future Climate Change

Wiley Members of the brown argus butterfly species that moved north in response to recent climate change have evolved a narrower diet dependent on wild Geranium plants, UK researchers report. However, butterflies that did not move north have more diverse diets, including plants such as Rockrose that are abundant in southern parts of the UK. So although rapid evolutionary changes have allowed the brown argus to move north and track the warming climate, they have led to a more restricted...

A new study led by scientists in the Department of Biology at the University of York has shown how a butterfly has changed its diet, and consequently has sped northwards in response to climate change. Their study is published in the latest issue of Science. The researchers found that warmer summers have allowed the Brown Argus butterfly to complete its life cycle by eating wild Geranium plants. Because the Geraniums are widespread in the British countryside, this change in diet has...

British Butterfly Evolving In Response To Climate Change

Evolutionary change helps species track ongoing climate warming As global temperatures rise and climatic zones move polewards, species will need to find different environments to prevent extinction. New research, published today in the journal Molecular Ecology, has revealed that climate change is causing certain species to move and adapt to a range of new habitats. The study, led by academics at the Universities of Bristol and Sheffield, aimed to understand the role of evolution in...
