“…Long-term warming of 1°C+ambient increased MT (fivefold), SQT (fourfold) and green leaf volatile (40%) emissions of Betula pendula ( Hartikainen et al, 2012 ). Ontogeny of needle development in terpene-storing conifers affects variability in MT emission rate responses to warming ( Esposito et al, 2016 ; Kivimäenpää et al, 2016 ; Ghimire et al, 2017 ; Tiiva et al, 2018 ). Some specific MTs of forest trees, particularly β-ocimene are known to be heat-stress indicators ( Jardine et al, 2017 ).…”

“…Shading by branch position can reduce isoprene and MT emissions from forest trees ( Esposito et al, 2016 ; Juran et al, 2017 ; van Meeningen et al, 2017 ). This suggests that cloudiness that reduces penetration of solar radiation to the canopy ( Niinemets, 2018 ) may reduce carbon allocation to volatile PSCs.…”

Climate Change Effects on Secondary Compounds of Forest Trees in the Northern Hemisphere

et al. 2018

Plant secondary compounds (PSCs), also called secondary metabolites, have high chemical and structural diversity and appear as non-volatile or volatile compounds. These compounds may have evolved to have specific physiological and ecological functions in the adaptation of plants to their growth environment. PSCs are produced by several metabolic pathways and many PSCs are specific for a few plant genera or families. In forest ecosystems, full-grown trees constitute the majority of plant biomass and are thus capable of producing significant amounts of PSCs. We summarize older literature and review recent progress in understanding the effects of abiotic and biotic factors on PSC production of forest trees and PSC behavior in forest ecosystems. The roles of different PSCs under stress and their important role in protecting plants against abiotic and biotic factors are also discussed. There was strong evidence that major climate change factors, CO2 and warming, have contradictory effects on the main PSC groups. CO2 increases phenolic compounds in foliage, but limits terpenoids in foliage and emissions. Warming decreases phenolic compounds in foliage but increases terpenoids in foliage and emissions. Other abiotic stresses have more variable effects. PSCs may help trees to adapt to a changing climate and to pressure from current and invasive pests and pathogens. Indirect adaptation comes via the effects of PSCs on soil chemistry and nutrient cycling, the formation of cloud condensation nuclei from tree volatiles and by CO2 sequestration into PSCs in the wood of living and dead forest trees.

“…There are no significant anthropogenic sources of VOCs near the five mountain sites under review; nevertheless, the surrounding forests are undoubtedly a major source of natural biogenic VOCs (further, BVOCs). BVOCs are a large group of organic chemicals including isoprene, terpenes, fatty acid derivates, benzenoids, phenylpropanoids, and amino acid derived metabolites (Esposito et al, 2016). They are emitted into the atmosphere by plants, and significantly affect its chemical composition and physical properties (Laothawornkitkul et al, 2009;Pinto et al, 2010), contributing substantially, among other effects, to the oxidizing capacity of the atmosphere through the recycling of hydroxyl radicals, OH (Lelieveld et al, 2008).…”

“…It has been widely accepted that the vegetative emissions display large inter-species and interindividual variability (Aydin et al, 2014). As compared to some other woody species, such as poplar or beech, spruce is a lower BVOC emitter (Bortsoukidis et al, 2014); however, it is still known to emit considerable amounts of reactive trace gases, and is considered particularly as an emitter of monoterpenes, such as α-pinene, β-pinene, limonene, and myrcene, whereas it is only a low isoprene emitter (Esposito et al, 2016;Jurán et al, 2017). Though some indicative information exists on BVOC emission for the CR (Zemankova and Brechler, 2010;Jurán et al, 2017), observation-based data in high time-resolution suitable for use in our model are lacking at present.…”

The aim of our study was to identify the factors substantially affecting day-to-day variability in O 3 concentrations in Czech mountain forests and to describe their influence in detailed, quantitative way. We examined the effects of meteorology and ambient NO x recorded in regular long-term continuous monitoring at five mountain forest sites representing different regions, covering both polluted and relatively unpolluted areas over the time period of 1992-2018. To investigate the association between ambient O 3 concentrations on one hand, and precursor NO x concentrations, and meteorology on the other hand, we used a generalized additive model, GAM, with semiparametric (penalized-spline-based) components to capture properly the possible departures from linearity that is not captured by traditional linear regression approaches. Our results revealed that the O 3 concentrations showed significant associations with all selected explanatory variables, i.e., air temperature, global solar radiation (GLRD), relative humidity, and NO x . Apparently, both meteorology and air pollution are highly important for day-to-day O 3 concentrations, and this finding is consistent for all five rural sites, representing middle-elevated forested mountain areas in Central Europe. In addition to individual variables, we were able to detect interactions between three pairs of explanatory variables, namely temperature * GLRD, temperature * relative humidity, and GLRD * relative humidity. Moreover, we confirmed non-linear O 3 behavior toward all individual explanatory variables.

“…Generally, terpenes act as herbivore deterrents, antibacterial and anti-mycotic substances [15], pollinator attractants and/or signals in plant-plant communication [16]. Terpenes (isoprene, mono-and sesquiterpenes) may be further involved in plant protection against abiotic stresses including extreme temperatures and/or drought [17,18]. The potential of terpenes to reduce ozone damage [19] and to quench reactive oxygen species [20] has also been demonstrated.…”

Plants produce specific terpenes, secondary metabolites conferring tolerance to biotic and abiotic stresses. Our study aims to investigate the effects of altitude, light intensity and season on contents of mono- and sesquiterpenes in needles of coniferous Norway spruce (Picea abies). Needles of current shoots representing upper and lower canopy were collected from adult trees growing along an altitudinal gradient (400–1100 m a.s.l.) in summer and autumn. After the extraction in cold heptane, the content of extractable terpenes was determined by gas chromatography coupled with mass spectrometry. Our results show that the total content of terpenes decreases with increasing altitude regardless of canopy position and season. Needles of the upper canopy have a higher total content of terpenes than lower canopy needles, but this difference decreases with increasing altitude in summer. Total content of extractable terpenes increases in autumn when compared to summer particularly in upper canopy needles of trees from high altitudes. Limonene, camphene, α-pinene and myrcene are the most abundant monoterpenes in spruce needles forming up to 85% of total monoterpenes, while germacrene D-4-ol is the most abundant sesquiterpene. Altitude, canopy position and season have a significant interactive effect on most monoterpenes, but not on sesquiterpenes. Terpenoid biosynthesis is thus tightly linked to growth conditions and likely plays a crucial role in the constitution of stress tolerance in evergreen conifers.
