The supply of nitrogen commonly limits plant production in boreal forests and also affects
species composition and ecosystem functions other than plant growth. These interrelations …

Forest trees are exposed to a myriad of single and combined stresses with varying strength
and duration throughout their lifetime, and many of the simultaneous and successive stress …

This report is the first complete assessment of the science of climate change since Working
Group I (WGI) of the IPCC produced its second report Climate Change 1995: The Science of …

In a decade-long soil warming experiment in a mid-latitude hardwood forest, we
documented changes in soil carbon and nitrogen cycling in order to investigate the …

The concentration of CO2 in the atmosphere has risen from close to 280 parts per million
(ppm) in 1800, at first slowly and then progressively faster to a value of 367 ppm in 1999 …

The global carbon budget is, of course, balanced. The conservation of carbon and the first
law of thermodynamics are intact.“Balancing the carbon budget” refers to the state of the …

Forest regeneration following disturbance is a key ecological process, influencing forest
structure and function, species assemblages, and ecosystem–climate interactions. Climate …

There is plenty of evidence for improved nutrient acquisition by ectomycorrhizas in trees;
however, their role in water uptake is much less clear. In addition to experiments showing …

Temperate and boreal forest ecosystems contain a large part of the carbon stored on land, in
the form of both biomass and soil organic matter. Increasing atmospheric [CO2], increasing …

Abstract free air carbon dioxide enrichment (FACE) and open top chamber (OTC) studies
are valuable tools for evaluating the impact of elevated atmospheric CO2 on nutrient cycling …
