Abstract Background In 1994, a “Pan-European Programme for Intensive and Continuous
Monitoring of Forest Ecosystems” started to contribute to a better understanding of the …

The present article portrays root growth and root system development with special reference
to Picea abies. Root phenology and ontogeny are depicted, and the biological responses of …

In order to contribute to a better understanding of the impact of air pollution and other
environmental factors on forest ecosystems, a Pan-European Programme for Intensive and …

This report describes the RAINS (Regional Acidification INformation and Simulation)
computer model, which provides a scientific overview of acidification, and links the science …

Symptoms of recent forest decline were first observed on silver fir (Abies alba) in the early
1970s in “clean-air” areas of southern Germany; they have subsequently been described in …

Site-specific estimates for various environmentalstress factors were related with measured
crowncondition data at a systematic 16×: 16 km 2 gridover Europe, according to previously …

After two decades of monitoring forest health in Europe, in response to concern for negative
effects of air pollution, a similar worry is now increasing in China. In a co-operative project …

Anaerobic fungi are known to migrate and establish a 3D network of biofilms (microbiomes)
and live invisible in the rumen and terrestrial subsurface, deep-sea-marine, and anoxic …

A study of mycorrhizal activity was conducted in a mature Norway spruce ((Picea abies)[L.]
Karst.) stand subjected to soil treatments of liming and acidification for six years (Höglwald …

Acidification is considered to be an unfavourable process in forest soil. Timber logging,
natural accumulation of biomass in the ecosystem, and acidic deposition are known sources …
