Opis:
Huricane force winds, extreme cold, dehydration, poor soils, uv radation, and intense sunlight challenge the survival of alpine wildflowers. Alpine plants display a fascinating array of adaptations to survive in the swiss Alps. This episode is filmed on location of a trail from San Bernardino, Switzerland in the Canton of Grisons or Graubruden. I describe and explain the myriad of adaptions to over come wind, cold, dehydration and uv radiation. There are so many fascinating adaptations to survival in the high mountains. I specifically point out the adaptations of Saxifrage as well as Edelweis.
