Signy Island is a biodiversity hot spot for lichens and other organisms in the Antarctic region. Here summer temperatures have increased over the past 50 years with the W Antarctic having the fastest rate of change in the S hemisphere. As a consequence of the rapid warming and glacial retreat, new areas are being exposed, providing opportunities for lichen colonisation. A recent field trip on Signy Island has provided new lichen material to complement historical collections, and to explore how biodiversity has responded to environmental change.
