“…BVOC emission rates of Scots pine were less responsive to 1°C elevation in air temperature than those of broad-leaved trees Populus tremula (Hartikainen et al 2009) and Betula pendula (Hartikainen et al 2012) but much more responsive than those of another common conifer species, Picea abies ). Our hypothesis of increased BVOC emissions by elevated ozone was supported, and our results are in agreement with the findings of Heiden et al (1999) and Kivimäenpää et al (2013), showing that chronic ozone concentrations exceeding 40 ppb or the critical value, 5 ppm.h, of AOT40 ozone exposure for forest trees (Mills et al 2010) can increase BVOC emissions from boreal conifers. The elevated ozone and elevated temperature enhanced the effects of each other on emission rates of bpinene in spring; otherwise, interaction of ozone with temperature was not a common response.…”

“…The difference may be due to the fact that VOC emission measured from the chamber air by Räisänen et al (2008) included emissions from soil, litter and the whole tree. The increased emissions reported here are in line with those from other juvenile boreal trees exposed to elevated temperature in the same exposure system (Hartikainen Kivimäenpää et al 2013). BVOC emission rates of Scots pine were less responsive to 1°C elevation in air temperature than those of broad-leaved trees Populus tremula (Hartikainen et al 2009) and Betula pendula (Hartikainen et al 2012) but much more responsive than those of another common conifer species, Picea abies ).…”

“…Photosynthetically active radiation (PAR) inside an empty bag and air temperature outside the bag at the canopy level were also recorded during BVOC collections (S-LIA-M003 for PAR and S-THA-M006 for temperature; Hobo Micro Station, Onset Computer Corporation, Bourne, MA, USA). The gas chromatography-mass spectrometry analysis with thermal desorption was done as described by Kivimäenpää et al (2012), and identification of terpenoids, green leaf volatiles (GLVs) and methylsalicylate as done by Kivimäenpää et al (2013). Emission rates of tricyclene and/or a-thujone are expressed as 'tricyclene/a-thujone' since their peaks were overlapping.…”

Increases in volatile organic compound emissions of Scots pine in response to elevated ozone and warming are modified by herbivory and soil nitrogen availability

Climate change in the boreal forests include, e.g., warming, increased tropospheric ozone concentration, higher nitrogen (N) deposition and increased risk of insect outbreaks. Climate change influences emissions of biogenic volatile organic compounds (BVOCs) affecting plant defense, communication and atmospheric feedbacks. We studied the effects of elevated temperature (ca. 1°C), elevated ozone (ca. 1.5 9 ambient), two soil N availability levels (prevailing and 120 kg N ha -1 a -1 ) and herbivory on BVOC emission rates, net photosynthesis and resin canals (BVOCs storage), of Scots pine (Pinus sylvestris) seedlings in an open-field exposure in central Finland. Shoot BVOCs were collected in July 2012 within a few days after feeding by larvae of pine-sawfly Acantholyda posticalis, a month later in August, and in May 2013. Elevated temperature caused twofold to fourfold increases in total emissions of non-oxygenated monoterpenes (MTs), oxygenated MTs and sesquiterpenes (SQTs) and several reactive compounds, and higher N enhanced some of these changes. Ozone and higher N together increased emissions of several MTs and total SQTs. Higher number of resin canals and higher net photosynthesis might have contributed to BVOC increases. Herbivory had the strongest effect on SQT emissions (threefold increase) shortly after feeding. In the following spring, herbivory reduced emission rates of some MTs, but also synergistically increased MTs emissions with temperature but suppressed the increase caused by ozone. Results suggest that warming and ozone, particularly in areas with increased soil N availability, can increase BVOC emissions from young boreal forests in the near future, and herbivory may modify these responses.

“…However, plants also emit a large amount of oxygenated VOCs (oxVOC) such as methanol (CH 4 O), acetaldehyde (C 2 H 4 O), ethanol (C 2 H 6 O) and acetone (C 3 H 6 O) (Kesselmeier and Staudt, 1999), the importance of which needs to be better addressed in future studies (Oderbolz et al,2013). Short-term laboratory experiments provide valuable information under controlled conditions, but their results are not comparable with longer term field experiments (Kivimäenpää et al, 2013) due to the controlled unnatural environments they grow in. Therefore, seasonal field campaigns that cover a wide spectrum of environmental and meteorological conditions are key for understanding emission responses and trends, along with the impact on ambient mixing ratios and atmospheric chemistry.…”

From emissions to ambient mixing ratios: online seasonal field measurements of volatile organic compounds over a Norway spruce-dominated forest in central Germany

Abstract. Biogenic volatile organic compounds (BVOCs) are substantial contributors to atmospheric chemistry and physics and demonstrate the close relationship between biosphere and atmosphere. Their emission rates are highly sensitive to meteorological and environmental changes with concomitant impacts on atmospheric chemistry. We have investigated seasonal isoprenoid and oxygenated VOC (oxVOC) fluxes from a Norway spruce (Picea abies) tree in central Germany and explored the emission responses under various atmospheric conditions. Emission rates were quantified by using dynamic branch enclosure and proton-transfer-reaction mass spectrometry (PTR-MS) techniques. Additionally, ambient mixing ratios were derived through application of a new box model treatment on the dynamic chamber measurements. These are compared in terms of abundance and origin with the corresponding emissions. Isoprenoids dominate the BVOC emissions from Norway spruce, with monoterpenes and sesquiterpenes accounting for 50.8 ± 7.2 % and 19.8 ± 8.1 % respectively of the total emissions. Normalizing the VOC emission rates, we have observed a trend of reduction of carbon-containing emissions from April to November, with an enhancement of oxVOC. Highest emission rates were observed in June for all measured species, with the exception of sesquiterpenes, which were emitted most strongly in April. Finally, we evaluate the temperature-dependent algorithm that seems to describe the temperature-dependent emissions of methanol, acetaldehyde and monoterpenes but only with the use of the monthly derived values for emission potential, E s , and temperature dependency, β factor.

“…This could be an addition to the increased biotic stress from native pest species Nordlander et al 2017) on forest trees in changed environmental conditions. BVOCs of forest trees are highly responsive to the abiotic (Peñuelas and Staudt 2010;Kivimäenpää et al 2013) and biotic Ghimire et al 2017) stresses related to climate change. Changes in BVOC emission profiles can predict survival of forest species and their further adaptation potential.…”

Unravelling the functions of biogenic volatiles in boreal and temperate forest ecosystems

Living trees are the main source of biogenic volatile organic compounds (BVOCs) in forest ecosystems, but substantial emissions originate from leaf and wood litter, the rhizosphere and from microorganisms. This review focuses on temperate and boreal forest ecosystems and the roles of BVOCs in ecosystem function, from the leaf to the forest canopy and from the forest soil to the atmosphere level. Moreover, emphasis is given to the question of how BVOCs will help forests adapt to environmental stress, particularly biotic stress related to climate change. Trees use their vascular system and emissions of BVOCs in internal communication, but emitted BVOCs have extended the communication to tree population and whole community levels and beyond. Future forestry practices should consider the importance of BVOCs in attraction and repulsion of attacking bark beetles, but also take an advantage of herbivore-induced BVOCs to improve the efficiency of natural enemies of herbivores. BVOCs are extensively involved in ecosystem services provided by forests including the positive effects on human health. BVOCs have a key role in ozone formation but also in ozone quenching. Oxidation products form secondary organic aerosols that disperse sunlight deeper into the forest canopy, and affect cloud formation and ultimately the climate. We also discuss the technical side of reliable BVOC sampling of forest trees for future interdisciplinary studies that should bridge the gaps between the forest sciences, health sciences, chemical ecology, conservation biology, tree physiology and atmospheric science.
