“…This same threshold effect was not observed for terpene foliar concentrations and terpene emissions from Mediterranean tree species and C4 crops (Blanch et al, 2009;Graus et al, 2013). However, other studies have demonstrated that under severe enough drought stress, monoterpene emissions also begin to decrease (Ormeno et al, 2007;Simpraga et al, 2011). Presumably, at some extreme, the plant shuts down metabolic activity and terpene pools, if present, are depleted.…”

Abstract. The largest global source of volatile organic compounds (VOCs) in the atmosphere is from biogenic emissions. Plant stressors associated with a changing environment can alter both the quantity and composition of the compounds that are emitted. This study investigated the effects of one global change stressor, increased herbivory, on plant emissions from five different coniferous species: bristlecone pine (Pinus aristata), blue spruce (Picea pungens), western redcedar (Thuja plicata), grand fir (Abies grandis), and Douglas-fir (Pseudotsuga menziesii). Herbivory was simulated in the laboratory via exogenous application of methyl jasmonate (MeJA), a herbivory proxy. Gas-phase species were measured continuously with a gas chromatograph coupled to a mass spectrometer and flame ionization detector (GC-MS-FID). Stress responses varied between the different plant types and even between experiments using the same set of saplings. The compounds most frequently impacted by the stress treatment were alpha-pinene, beta-pinene, 1,8-cineol, beta-myrcene, terpinolene, limonene, and the cymene isomers. Individual compounds within a single experiment often exhibited a different response to the treatment from one another.

“…Because drought stress often co-occurs with elevated air temperatures, the combined effect of both factors also has to be taken into account. Several studies have indicated that moderately reduced soil water availability does not affect or rather slightly stimulates isoprenoid emissions [65][66][67]. In contrast, strongly reduced water availability affects the biosynthesis of isoprenoids, thereby decreasing their emissions [66][67][68][69][70][71][72][73].…”

High levels of air pollution including ground level ozone significantly reduce humans' life expectancy and cause forest damage and decreased tree growth. The French Vosges and the German Black Forest are regions well-known for having the highest tropospheric ozone concentrations at remote forested sites in Central Europe. This box model study investigates the sensitivity of atmospheric chemistry calculations of derived ozone on differently resolved forest tree composition and volatile organic compound emissions. Representative conditions were chosen for the Upper Rhine area including the Alsatian Vosges/France and the Black Forest/Germany during summer. This study aims to answer the following question: What level of input detail for Alsace and Black Forest tree mixtures is required to accurately simulate ozone formation? While the French forest in Alsace-e.g., in the Vosges-emits isoprene to a substantially higher extent than the forest at the German site, total monoterpene emissions at the two sites are rather similar. However, the individual monoterpene structures, and therefore their reactivity, differs. This causes a higher ozone production rate for Vosges forest mixture conditions than for Black Forest tree mixtures at identical NO x levels, with the difference increasing with temperature. The difference in ozone formation is analyzed in detail and the short-comings of reduced descriptions are discussed. The outcome serves as a to-do-list to allow accurate future ozone predictions influenced by the climate adaptation of forests and the change in forest species composition.

Llusià and Peñue-las (1998) found strong suppression of MT emissions from non-storing species such as Holm oak and a significant relation between net assimilation and MT emissions.…”

“…Some studies show increasing emissions with decreasing soil moisture (Bertin and Staudt, 1996;Blanch et al, 2007;Ormeño et al, 2007), others show decreasing emissions with increasing severity of drought (Lavoir et al, 2009;Šimpraga et al, 2011). Besides this, different reference quantities have been used to characterize the soil moisture level.…”

Abstract. Impacts of soil moisture on de novo monoterpene (MT) emissions from Holm oak, European beech, Scots pine, and Norway spruce were studied in laboratory experiments. The volumetric water content of the soil, , was used as the reference quantity to parameterize the dependency of MT emissions on soil moisture and to characterize the severity of the drought.When dropped from 0.4 m 3 × m −3 to ∼ 0.2 m 3 × m −3 slight increases of de novo MT emissions were observed but with further progressing drought the emissions decreased to almost zero. In most cases the increases of MT emissions observed under conditions of mild drought were explainable by increases of leaf temperature due to lowered transpirational cooling. When fell below certain thresholds, MT emissions decreased simultaneously with and the relationship between and MT emissions was approximately linear. The thresholds of (0.044-0.19 m 3 × m −3 ) were determined, as well as other parameters required to describe the soil moisture dependence of de novo MT emissions for application in the Model of Emissions of Gases and Aerosols from Nature, MEGAN.A factorial approach was found appropriate to describe the impacts of , temperature, and light. Temperature and influenced the emissions largely independently from each other, and, in a similar manner, light intensity and acted independently on de novo MT emissions. The use of as the reference quantity in a factorial approach was tenable in predicting constitutive de novo MT emissions when changed on a time scale of days. Empirical parameterization with as a reference was only unsuccessful when soil moisture changed rapidly
