North American and European treelines: external forces and internal processes controlling position

Article Abstract:

An evaluation is presented on the concepts of tree material limitation and increased environmental hazard as tools to assess forest dynamics. It is posited that field manipulation of environmental conditions will be necessary to develop evaluation tools that are both predictive and explanatory, and that this manipulation will need to be applied to many tree species at and below the treeline in many geographic locations.

New estimate of the carbon sink strength of EU forests integrating flux measurements, field surveys, and space observations: 0.17-0.35 Gt(C)

Article Abstract:

Carbon sink strength estimates can be achieved through eddy covariance flux measurements. Tested on forests of the European Union, the method directly estimates ecosystem net carbon exchanges. Results indicate that policies are needed to protect natural resources, particularly forests, due to their role in global carbon cycle processes and their propensity to act as sinks for greenhouse gases.

20th century climate warming and tree-limit rise in the southern Scandes of Sweden

Article Abstract:

Research shows an increase in the elevation of tree-limits in the Swedish region of the Scandinavian mountains over the past century. Multispecies elevational tree-limits have advanced upward by more than 100 m, and are linked to a rise in temperature of ca. 0.8 degrees C during this period.
