Main gaps: 1. We need funding for winter measurements allowing us to study ecosystem dynamics outside the growing season. Recent research has demonstrated that important components of ecosystem dynamics occur after the growing season (e.g. Post et al. 2009: Science 325, 1355-1358; Mastepanov et al. 2008: Nature 456, 628-630.). 2. We need funding for increased circum-arctic cooperation between monitoring sites to facilitate comparative studies of ecosystem dynamics in different compartments of the Arctic.
