New research shows that butterflies have expanded their ranges over the past 120 years to cope with a warmer climate in Sweden and Finland. Although driven by a warmer climate, range expansions have also been influenced by human land use and vary according to species thermal tolerances and habitat preferences. The increased species richness and modified community composition of butterflies may impact ecosystem functioning.
Fascinating read. I am working to make my garden more wildlife friendy. Ive introduced lots of flowerd the last 10 years, but will work on bringing in more native flowers onwards. Hopefully the butterflies will like it.
