Nel corso di una campagna triennale, dal 2013 al 2015, sono state misurate le concentrazioni di ozono, il flusso di NO proveniente dal suolo, il flusso di Isoprene, i parametri meteorologici (temperatura, rH, precipitazioni, direzione dei venti, radiazione solare), il contenuto di umiditá nel suolo e l’altezza della falda acquifera. Tali misure son...

Drought and salt are key abiotic stressors in temperate cities. Biogenic volatile organic compound (BVOC) emissions, often dominated by trees, influence the urban troposphere and mediate plant-plant and plant-insect interactions. While knowledge on constitutive BVOC emissions is increasing, modulation of blends by stress has yet received little att...

Supplement to Fitzky et al. 2023. Same, same, but different: drought and salinity affect BVOC emission rate and alter blend composition of urban trees. Urban Forestry & Urban Greening. DOI: 10.1016/j.ufug.2023.127842

Austria Biogenic volatile organic compounds (BVOCs) emitted by plants consist of a broad range of gasses which serve purposes such as protecting against herbivores, communicating with insects and neighboring plants, or increasing the tolerance to environmental stresses. Evidence is accumulating that the composition of BVOC blends plays an important...

Terpenoid emissions above urban areas are a complex mix of biogenic and anthropogenic emission sources. In line with previous studies we found that summertime terpenoid fluxes in an alpine city were dominated by biogenic sources. Inter-seasonal emission measurements revealed consistency for monoterpenes and sesquiterpenes but a large difference in...

Terpenoid emissions above urban areas are a complex mix of biogenic and anthropogenic emission sources. In line with previous studies we found that summertime terpenoid emissions in an alpine city were dominated by biogenic sources, but especially at lower temperatures the anthropogenic influences were non-negligible. Inter-seasonal emission measur...

Fish are some of the most threatened vertebrates in the world due to their often-sensitive response to environmental changes. Major land-use changes in the European Alps have direct and indirect impacts on fish communities, and these impacts are expected to increase in the future. Therefore, the identification of factors that are associated with th...

Volatile organic compounds (VOCs) emitted by plants consist of a broad range of gasses which serve purposes such as protecting against herbivores, communicating with insects and neighboring plants, or increasing the tolerance to environmental stresses. Evidence is accumulating that the composition of VOC blends plays an important role in fulfilling...

Drought events are expected to become more frequent with climate change. To predict the effect of plant emissions on air quality and potential feedback effects on climate, the study of biogenic volatile organic compound emissions under stress is of great importance. Trees can often be subject to a combination of abiotic stresses, for example due to...

METHODS Tree species have been selected according to their frequency in Vienna, Austria, and to cover all types of emissions, we selected Carpinus betulus as a low-emitting tree species, Quercus robur as a high isoprene emitter, Fagus sylvatica as a monoterpene emitter, Betula pendula as a sesquiterpene emitter. The different tree species have been...

In two areas of the Alps several analyses aiming to verify the presence of PAH and heavy metals deposition have been performed during the ablation season 2016. In relation to the different precipitation regime, exposition and elevation we selected three alpine glaciers owing their peculiar conditions: the Gran Pilastro glacier-Gliderferner, located...
