Short distance dispersal of seeds in glacier foreland species in the Swiss Alps (% of trapped seeds). Seeds were trapped with glue on petri dishes arranged in 4 circles with increasing radius around mother plants. % trapped diaspores was calculated from the number of trapped diaspores per circle using a correction factor for increasing perimeter. From Stöcklin and Bäumler 1996.
