This work presents a detailed inventory of isoprenoid emissions from vegetation in Italy using an original approach which combines state of the art models to estimate the species-specific isoprenoid emissions and a Geographic Information System (GIS) where emissions are spatially represented. Isoprenoid species and basal emission factors were obtained by combining results from laboratory experiments with those published in literature. For the first time, our investigation was not only restricted to isoprene and total monoterpenes, but our goal was to provide maps of isoprene and individual monoterpenes at a high-spatial (∼1 km2) and temporal resolution (daily runs, monthly trends in emissions are discussed in the text). Another novelty in our research was the inclusion of the effects of phenology on plant emissions. Our results show that: a) isoprene, a-pinene, sabinene and b-pinene are the most important compounds emitted from vegetation in Italy; b) annual biogenic isoprene and monoterpene fluxes for the year 2006 were ∼31.30 Gg and ∼37.70 Gg, respectively; and c) Q. pubescens+Q. petrea+Q. robur, Q. ilex, Q. suber and Fagus sylvatica are the principal isoprenoid emitting species in the country. The high spatial and temporal resolution, combined with the species-specific emission output, makes the model particularly suitable for assessing local budgets, and for modelling photochemical pollution in Italy.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Steinbrecher, Rainer</style></author><author><style face="normal" font="default" size="100%">Smiatek, Gerhard</style></author><author><style face="normal" font="default" size="100%">Köble, Renate</style></author><author><style face="normal" font="default" size="100%">Seufert, Günther</style></author><author><style face="normal" font="default" size="100%">Theloke, Jochen</style></author><author><style face="normal" font="default" size="100%">Hauff, Karin</style></author><author><style face="normal" font="default" size="100%">Ciccioli, Paolo</style></author><author><style face="normal" font="default" size="100%">Vautard, Robert</style></author><author><style face="normal" font="default" size="100%">Curci, Gabriele</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Intra- and inter-annual variability of VOC emissions from natural and semi-natural vegetation in Europe and neighbouring countries</style></title><secondary-title><style face="normal" font="default" size="100%">Atmospheric Environment</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">BVOC</style></keyword><keyword><style  face="normal" font="default" size="100%">Emission modelling</style></keyword><keyword><style  face="normal" font="default" size="100%">Inventory</style></keyword><keyword><style  face="normal" font="default" size="100%">Isoprenoids</style></keyword><keyword><style  face="normal" font="default" size="100%">oxyVOC</style></keyword><keyword><style  face="normal" font="default" size="100%">Sequiterpenes</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2009///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S1352231008008868</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">43</style></volume><pages><style face="normal" font="default" size="100%">1380 - 1391</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Biogenic VOC emission estimates from the earth’s surface are crucial input parameters in air quality models.

With regard to the carbon budget of the terrestrial biosphere, a release of these carbon compounds is regarded as a loss of photosynthetically fixed carbon. The significance of this loss for the regional and global carbon cycles is controversial. We estimate the amount of VOC carbon emitted in relation to the CO2 taken up, based on our own enclosure and micrometeorological flux measurements of VOC emissions and CO2 exchange within the Mediterranean area and the tropical rainforest in Amazonia and on literature data. While VOC flux estimates are small in relation to net primary productivity and gross primary productivity, the amount of carbon lost as VOC emissions can be highly significant relative to net ecosystem productivity. In fact, VOC losses are of the same order of magnitude as net biome productivity. Although we must assume that large amounts of these reemissions are recycled within the biosphere, a substantial part can be assumed to be lost into longer-lived oxidation products that are lost from the terrestrial biosphere by transport. However, our current knowledge does not allow a reliable estimation of this carbon loss.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Loreto, Francesco</style></author><author><style face="normal" font="default" size="100%">Ciccioli, Paolo</style></author><author><style face="normal" font="default" size="100%">Brancaleoni, Enzo</style></author><author><style face="normal" font="default" size="100%">Valentini, Riccardo</style></author><author><style face="normal" font="default" size="100%">De Lillis, Manuela</style></author><author><style face="normal" font="default" size="100%">Csiky, Olav</style></author><author><style face="normal" font="default" size="100%">Seufert, Guenther</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A hypothesis on the evolution of isoprenoid emission by oaks based on the correlation between emission type and Quercus taxonomy</style></title><secondary-title><style face="normal" font="default" size="100%">Oecologia</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">chemo-taxonomy</style></keyword><keyword><style  face="normal" font="default" size="100%">Evolution</style></keyword><keyword><style  face="normal" font="default" size="100%">isoprenoid emission</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1998</style></year></dates><volume><style face="normal" font="default" size="100%">115</style></volume><pages><style face="normal" font="default" size="100%">302-305</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We show that Mediterranean oaks that emit isoprene, monoterpenes or no isoprenoids belong to dierent subgenera as indicated by morpho-taxonomy and molecular genetics. On the other hand, oaks from North America and Asia that are taxonomically similar to the Mediterranean monoterpene emitter Q. ilex emit isoprene only. We surmise that isoprene emission is a genetic character which evolved ancestrally in the oak genus since this is the prevalent emission type in oaks widespread around the world and adapted to dierent environments. This ancestral character may have been either lost or modi®ed in more recent clades such as those originating the Mediterranean oaks. If our hy- pothesis is correct then the taxonomy of European oaks is validated by this independent trait. Isoprenoid emis- sion could serve as a chemo-taxonomical marker and could be used to reconstruct the phylogeny of oaks in association with molecular markers.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Loreto, Francesco</style></author><author><style face="normal" font="default" size="100%">Ciccioli, Paolo</style></author><author><style face="normal" font="default" size="100%">Brancaleoni, Enzo</style></author><author><style face="normal" font="default" size="100%">Cecinato, Angelo</style></author><author><style face="normal" font="default" size="100%">Frattoni, Massimiliano</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Measurement of isoprenoid content in leaves of Mediterranean Quercus spp. by a novel and sensitive method and estimation of the isoprenoid partition between liquid and gas phase inside the leaves</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Isoprene emission (content)</style></keyword><keyword><style  face="normal" font="default" size="100%">Monoterpene emission (content): Quercus spp.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1998</style></year></dates><volume><style face="normal" font="default" size="100%">136</style></volume><pages><style face="normal" font="default" size="100%">25-30</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We used a novel. simple and sensitive method to extract isoprenoids contained in the leaves and compared emission and content of isoprenoids in the leaves of three Mediterranean oak species emitting isoprene (Quercus puhcsccws), monoterpenes (Querc~s ilrs) or non-emitting isoprenoids (Quercus cerris). The content is qualitatively consistent with the emission of isoprenoids by Qucrczls spp. However. the fraction of isoprenoids in the gas phase was estimated to be r 0.02 and 5% of the total content for monoterpenes and isoprene, respectively. On the other hand, the content of monoterpenes in the leaf was much higher than that of isoprene and particularly rich of compounds which can hardly be detected in an emission such as linalool. It is concluded that isoprenoids are contained in temporary pools and that the different partition between gas and liquid phases plays an important role in determining the pool size in isoprene and monoterpene-emitting oaks. The pools of isoprenoid-emitting oaks sustain the emission for few minutes when isoprenoid formation is prevented. which rules out the presence of specialized organs for isoprenoid storage and are absent altogether in non-emitting species.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ciccioli, Paolo</style></author><author><style face="normal" font="default" size="100%">Fabozzi, Concetta</style></author><author><style face="normal" font="default" size="100%">Brancaleoni, Enzo</style></author><author><style face="normal" font="default" size="100%">Cecinato, Angelo</style></author><author><style face="normal" font="default" size="100%">Frattoni, Massimiliano</style></author><author><style face="normal" font="default" size="100%">Loreto, Francesco</style></author><author><style face="normal" font="default" size="100%">Kesselmeier, Jürgen</style></author><author><style face="normal" font="default" size="100%">Schäfer, Luise</style></author><author><style face="normal" font="default" size="100%">Bode, Kirsten</style></author><author><style face="normal" font="default" size="100%">Torres, Liberto</style></author><author><style face="normal" font="default" size="100%">Fugit, Jean-Luc</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Use of the isoprene algorithm for predicting the monoterpene emission from the Mediterranean holm oak Quercus ilex L.: Performance and limits of this approach</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Geophysical Research: Atmospheres</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biogenic emission</style></keyword><keyword><style  face="normal" font="default" size="100%">isoprene algorithm</style></keyword><keyword><style  face="normal" font="default" size="100%">monoterpene (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">Temperature</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><volume><style face="normal" font="default" size="100%">102</style></volume><pages><style face="normal" font="default" size="100%">23319-23328</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The algorithm developed by Guenther et al.
