In the context of the EU GLOCHAMORE project (Global Change in Mountain Regions, 2003–2005) a workshop was held on Altitudinal Gradient Studies from 27 to 30 July 2005 in Samedan/Switzerland. The main topic of the workshop was ecology and ecosystem processes (see “Ecological and land use studies along altitudinal gradients,” Becker et al 2007). Other issues that arose at the workshop, including general aspects and hydrological and geomorphological issues, are presented here in brief.
