View from Clavering Island towards the mainland (Photo: Fritz Hans Schwarzenbach, 2001) SLF biologists are retracing two expeditions undertaken 20 and 90 years ago. Like their predecessors, they will be recording the plant populations they come across, and analysing how these have changed over recent decades. They expect this to provide new insights into the effects of climate change. Biologists Christian Rixen and Andreas Gygax from the WSL Institute for Snow and Avalanche Research (SLF) set off for Greenland on 25 July, following in the footsteps of two earlier scientists. Back in 1931 and 1932, Danish botanist Paul Gelting made an inventory of the plants between sea level and an altitude of 1,200 metres on Clavering Island off the coast of north-east Greenland. He recorded all the species present there at every 100 metres in altitude. In 2001, Swiss biologist Fritz Hans Schwarzenbach repeated the expedition.
