The Brown Argus Butterfly

This article talks about species having to adapt and change habitats due to climate change. This piece focuses on the Brown Argus butterfly in the UK. Although they are trying to adapt it becomes very hard because the farther north they go the less preferred habitat they find. The Brown Argus has been able to adapt and successfully has been able to expand north in the UK.  Using genetic techniques to detect evolutionary change, the researchers were able to show that the colonization of new sites further north by the Brown Argus has involved significant adaptation during or following colonization. This is one of the first studies to identify genetic evidence for evolutionary change associated with range shifts driven by recent climate change.
