| Summary: | hemes with a large-scale design needs to be initiated to better ween climate, food web dynamics and their relations to Arctic and is particularly highlighted (Callaghan et al., 2004b; Foley, 2005; Hinzman et al., 2005; Chapin et al., 2005). However, cli-mate change takes place in conjunction with several other anthropogenic stressors, such as intensified land use (CAFF, 2003; ACIA, 2004). Although the entire Arctic region may be tors) may be particularly sensitive to fundamental ecosystem alterations (Schmitz et al., 2003; Sergio et al., 2005; Voigt et al., 2003). Tundra ecosystems have typically a tri-trophic, plant-based food web topped by a guild of predators preying mainly on herbivorous small mammals (lemmings and voles) (Elton |
