European beech (Fagus sylvatica L.) forests provide multiple essential ecosystem goods and ser-vices. The projected climatic conditions for the current century will significantly affect the vital-ity of European beech. The expected impact of climate change on forest ecosystems will be po-tentially stronger in southeast Europe than on the rest of th...

Despite the importance of vegetation uptake of atmospheric gaseous elemental mercury (Hg(0)) within the global Hg cycle, little knowledge exists on the physiological, climatic, and geographic factors controlling stomatal uptake of atmospheric Hg(0) by tree foliage. We investigate controls on foliar stomatal Hg(0) uptake by combining Hg measurements...
Article

Most trees form symbioses with ectomycorrhizal fungi (EMF) which influence access to growth-limiting soil resources. Mesocosm experiments repeatedly show that EMF species differentially affect plant development, yet whether these effects ripple up to influence the growth of entire forests remains unknown. Here we tested the effects of EMF compositi...

Resource allocation to different plant tissues is likely to be affected by high investment into fruit production during mast years. However, there is a large knowledge gap concerning species-specific differences in resource dynamics. We investigated the influence of mast years on stem growth, leaf production, and leaf carbon (C), nitrogen (N), and...

When studying forest responses to climate change it is important to consider tree nutrition. Enhanced atmospheric deposition of nitrogen, atmospheric carbon dioxide enrichment, and higher temperatures and longer growing seasons have stimulated tree growth in many parts of Europe. Increased tree growth can lead to increased nutrient demand. In fores...
Article
In boreal forests, snow typically covers the forest floor and insulates soil from low and fluctuating air temperature for a large part of the year. Snowpack regimes are currently changing in response to climate warming, and it is uncertain how changing subnivean conditions (i.e. those under the snow cover) will impact soil processes. Here, we exper...
Article
Changing environmental conditions may substantially interact with site quality and forest stand characteristics, and impact forest growth and carbon sequestration. Understanding the impact of the various drivers of forest growth is therefore critical to predict how forest ecosystems can respond to climate change. We conducted a continental-scale an...
Article
The quantitative assessment of forest management impacts on ecosystem services calls for ecological models to be linked to forest planning systems. In these systems, such models are expected to produce valid and accurate predictions to quantify the effects of alternative forest management strategies on ecosystem services. As an example, we present...
Article
Global warming is predicted to affect ecosystems, particularly in high-latitude regions where polar amplification accelerates temperature rise and environmental changes. Here, where plants grow under adverse conditions, a warmer climate provides more favourable conditions for growth and regeneration. At the alpine and polar tree line in Finnish Lap...

Environmental policies of the European Union aim to increase recycling and re-use of waste-streams. One of the economically most profitable ways of re-using waste is to use it as a fertilizer. In this study, recycled nitrogen fertilizers were manufactured from industrial side-streams (sawdust, fly-ash, ammonium sulfate and lignosulfonate). A sequen...
Article
The objective of the study was to examine the success of regeneration in gaps of variable size in pine-dominated stands in terms of seedling density. It was based on an experiment in central Lapland containing circular clear-cut gaps of 20, 40 and 80 m in diameter on typical sub-xeric and xeric pine sites with site preparation (patch scarification)...
Article
Air temperatures and precipitation are predicted to increase in the future, especially at high latitudes and particularly so during winter. In contrast to air temperatures, changes in soil temperatures are more difficult to predict, as the fate of the insulating snow cover is crucial in this respect. Soil conditions can also be affected by rain-on-...

Explaining the large-scale diversity of soil organisms that drive biogeochemical processes-and their responses to environmental change-is critical. However, identifying consistent drivers of belowground diversity and abundance for some soil organisms at large spatial scales remains problematic. Here we investigate a major guild, the ectomycorrhizal...
Article
Sphagnum mosses are the key regulating component in peatland ecosystems. Although their importance in sustainability of peatlands and overall impact on the Earth’s carbon, nutrient and hydrological balance are well recognised, our knowledge of the effects of enhanced ultraviolet B (UV-B) radiation on peat mosses is in- sufficient. Analogous studies of...

Article
For social foragers, movement as a group could increase foraging efficiency through collective discovery of high-quality food sources. This would require an efficient mechanism for transferring information about food quality between individuals. Conversely, the constraints of foraging as a cohesive group could decrease efficiency; grouping may pers...
Research Proposal
Scientific research and forest management practices are two strategic levers that can be activated to better preserve forest biodiversity. These interacting fields of activities feed public policies and vice versa. They are organized in different ways and at different scales across countries, driven by various stakeholders and individuals. Our main...

Article
Future climate scenarios predict increased air temperatures and precipitation, particularly at high latitudes, and especially so during winter. Soil temperatures, however, are more difficult to predict, since they depend strongly on the fate of the insulating snow cover. ‘Rain-on-snow’ events and warm spells during winter can lead to thaw–freeze cy...
Conference Paper
Full-text available
Frequency of rain-on-snow events and winter warm spells is increasing in high latitudes and is forecasted to further increase in the future. By decreasing the insulation capacity of the snowpack and causing ice layers or ground ice encasement (IE), those events have the potential to lead to colder soil but also to hypoxia and accumulation of trace...
Article
Coniferous trees at the alpine and polar tree lines of the Northern Hemisphere represent the outermost limit of their ecological range. Under such conditions, even small temperature variations may cause growth responses, which therefore can be used as indicators for changing environmental conditions. In this study we analysed the radial growth of S...
Article
Environmental policies of the European Union (EU) aim to increase the amount of renewable energy and to improve the use of waste streams. This will increase the amount of fly ash (FA) from biomass combustion, thereby increasing the need for its utilization. Biomass FA is a good fertilizer since it contains most of the nutrients that plants need. Se...

At high latitudes, the climate has warmed at twice the rate of the global average with most changes observed in autumn, winter and spring. Increasing winter temperatures and wide temperature fluctuations are leading to more frequent rain-on-snow events and freeze-thaw cycles causing snow compaction and formation of ice layers in the snowpack, thus...

The boreal timber- and tree-line forests grow in harsh environmental conditions in their outermost distribution limit. In these conditions even small environmental changes, like e.g. a higher temperature sum or a prolonged growing season, may cause dramatic changes in the distribution of tree species. We examined changes of the forest lines of Norw...

Key message Foliar phosphorus concentrations have decreased in Europe during the last 20 years. High atmospheric nitrogen deposition and climate change might be responsible for this trend. Continued decrease in foliar P concentrations might lead to reduced growth and vitality of beech forests in Europe. Context Increased forest soil acidification,...
Article
Flood meadows represent semi-natural vegetation by the great rivers in northern Finland. Physical forces acting on the river banks such as ice, floods and annual sedimentation create temporarily oxygen-free conditions as well as open space for the growth of grasses and herbs. Besides flood dynamics, clearing and mowing for winter forage maintained...

The response of forest ecosystems to increased atmospheric CO2 is constrained by nutrient availability. It is thus crucial to account for nutrient limitation when studying the forest response to climate change. The objectives of this study were to describe the nutritional status of the main European tree species, to identify growth limiting nutrien...
Article
Understanding the relationship between nitrogen (N) availability and stand health in forest ecosystems is crucial, because a large proportion of European forests is subjected to N-deposition levels beyond their retention capacity. We used data from a long-term forest monitoring programme (ICP Forests) to test the relationship between an index of N...
Article
Nitrogen (N) is typically the growth-limiting factor in boreal forest ecosystems. Therefore, knowledge on forest N stocks and fluxes is crucial in order to predict and evaluate the effects of different anthropogenic factors (e.g. climate change, air pollutant deposition, forest management practices) on the condition, development and sustainability...
