Over the past 20 years, the focus of forest science on air pollution has moved from forest decline to a holistic framework of forest health, and from the effects on forest production to the ecosystem services provided by forest ecosystems. Hence, future research should focus on the interacting factorial impacts and resulting antagonistic and synergistic(More)
Outcomes from the 22nd meeting for Specialists in Air Pollution Effects on Forest Ecosystems "Forests under Anthropogenic Pressure--Effects of Air Pollution, Climate Change and Urban Development", September 10-16, 2006, Riverside, CA, are summarized. Tropospheric or ground-level ozone (O3) is still the phytotoxic air pollutant of major interest. Challenging(More)
The results of long-term investigations of Scots pine (Pinus sylvestris L.) growth and condition in the impact zone of one of the biggest air pollution sources in Lithuania--mineral fertilizers plant "Achema" are presented. The main attention is laid to the recovery of damaged stands since annual emissions to air were reduced essentially. The investigations(More)
Long-term investigations of Scots pine (Pinus sylvestris L.) growth were carried out in the vicinity of one of the biggest air pollution sources in Lithuania—mineral fertilizers plant “Achema.” It is detected that initial stages of the dynamic tree response to the external stress factors in the polluted environment with an increased quantity of nitrogen(More)
The study aimed to explore if changes in crown defoliation and stem growth of Scots pines (Pinus sylvestris L.) could be related to changes in ambient ozone (O(3)) concentration in central Europe. To meet this objective the study was performed in 3 Lithuanian national parks, close to the ICP integrated monitoring stations from which data on meteorology and(More)
The multiple-stressor effects of air pollution, nutrient and water availability are the key issues of present forest ecosystem research. However, too little is known about the seasonal effect of pollutants on tree crown defoliation and their interaction with changes in climate. Therefore, data on seasonal variation in air pollution, including surface ozone,(More)
logical Reactions of Forests to Climate Change and Air Pollution'' was held in Kaunas/Lithuania under the auspices of the International Union of Forest Research Organizations (IUFRO), represented by the Working Group 7.01.00 (chaired by Andrzej Bytnerowicz and Elena Paoletti) on ''Impacts of Air Pollution and Climate Change on Forest Ecosystems.'' Local(More)
This study aimed to explore if changes in peak ozone (O3) concentrations may reinforce the phytotoxic effects of air concentration of acidifying compounds and their deposition, as well as unfavorable climatic factors on pine crown defoliation. Forty-eight pine stands with more than 8000 sample pine trees have been monitored annually. The impact of sulfur(More)
The present study aimed to detect sensitivity of beech trees (Fagus sylvatica L.) to meteorological parameters and air pollution by acidifying species as well as to surface ozone outside their north-eastern distribution range. Data set since 1981 of Preila EMEP station enabled to establish that hot Summers, cold dormant, and dry and cold first-half of(More)
The presented study aimed to explore the relationships between ambient ozone (O3) and tree defoliation, specific diversity, and abundance of soil microarthropods, stream macroinvertebrates, and small mammals (mainly rodents) in order to test the hypothesis that changes in the considered objects of the forest ecosystem could be related to changes in ambient(More)
