Growth‐ring variations of dwarf shrubs reflect regional climate signals in alpine environments rather than topoclimatic differences
Aim Our main aim is to determine if ring‐width variations in Empetrum hermaphroditum reflect regional or local topoclimate signals in an alpine environment. In the case that topoclimate provides the…

The wider oak rings that are exhibited during this period may be indicative of a nonlinear or threshold-induced growth response to drought and vapor pressure, and run counter to the general response of oak to droughtand precipitation that normally would result in suppressed growth in a warmer and drier environment.
Climate Change, Land Use Conflicts, Predation and Ecological Degradation as Challenges for Reindeer Husbandry in Northern Europe: What do We Really Know After Half a Century of Research?
This review illuminates whether or not research is capable to match the challenges of reindeer husbandry and proposes some targets for new integrative research approaches that incorporate traditional knowledge and focus on the entire human-ecological system ‘reindeerhusbandry’ to develop solutions for its challenges.
Dendroecology of dwarf shrubs in the high mountains of Norway – A methodological approach
Species-specific climate sensitivity of tree growth in Central-West Germany
Species-specific and regional differences in long-term climate sensitivities, as evidenced by temporal variability in drought sensitivity, are potential indicators for a changing climate that effects Central-West German forest growth, but meanwhile hampers a general assessment of these effects.
Ring-Width Chronologies of the Alpine Dwarf Shrub Empetrum Hermaphroditum FROM THE NORWEGIAN MOUNTAINS
In this study, we present the first ring-width chronologies of the dwarf shrub species Empetrum hermaphroditum. For a proper synchronization of the growth rings, serial sectioning was applied in…
The alpine treeline under changing land use and changing climate: Approach and preliminary results from continental Norway
This study aims at improving the comprehension of the alpine treeline, partly as a means of projecting landscape evolution in an anticipated warmer future. The main problem to be solved is to…
Ecosystem services in coupled social–ecological systems: Closing the cycle of service provision and societal feedback
This paper closed a cycle of ecosystem service provision and societal feedback by rethinking and reassembling the core elements of both models and established a causal sequence apt to describe the causes of change to SES, their effects and their consequences.
Deepened winter snow increases stem growth and alters stem δ13C and δ15N in evergreen dwarf shrub Cassiope tetragona in high-arctic Svalbard tundra
Deeper winter snow is hypothesized to favor shrub growth and may partly explain the shrub expansion observed in many parts of the arctic during the last decades, potentially triggering biophysical…
