DESCRIPTION: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 ch
 ange in the S hemisphere. As a consequence of the rapid warming and glacia
 l retreat\, new areas are being exposed\, providing opportunities for lich
 en colonisation. A recent field trip on Signy Island has provided new lich
 en material to complement historical collections\, and to explore how biod
 iversity has responded to environmental change.
