Wood anatomical analysis of Swiss willow (Salix helvetica) shrubs growing on creeping mountain permafrost
Permafrost and related landforms (rockglaciers) are widespread phenomena in alpine geosystems. In the context of changing environments due to the significant warming, there is a need for thorough monitoring and analyzing the complex responses of these cryospheric geosystems. Here, the first-time app...

Permafrost and related landforms (rockglaciers) are widespread phenomena in alpine geosystems.

In order to determine the influence of ground movements (by permafrost creep) and their influence on the conductive elements within roots of plants, wood-samples were taken from active and inactive rockglaciers in the Turtmann Valley, southern Swiss Alps.
