Recent vegetation phenology variability and wild reindeer migration in Hardangervidda plateau (Norway)
More than others, arctic ecosystems are affected by consequences of global climate changes. The herbivorous plays numerous roles both in Scandinavian natural and cultural landscapes (Forbes et al., 2007). Wild reindeer (Rangifer tarandus L.) herds in Hardangervidda plateau (Norway) constitute one of...

More than others, arctic ecosystems are affected by consequences of global climate changes.
