Yet the occurrence of adverse effects of O3 on forests and crops is controversial. Possible reasons include (i) ability of response indicators to provide an unbiased estimate of O3 effects, (ii) setting of current CLe(c) in terms of cut-off value and accumulation level, (iii) response functions adopted to infer a critical level, (iv) environmental limitation to O3 uptake and (v) inherent characteristics of Mediterranean vegetation. In particular, the two latter points suggest that critical levels based on accumulated stomatal flux (CLe(f)) can be a better predictor of O3 risk than CLe(c). While this concept is largely acknowledged, a number of factors may limit its applicability for routine monitoring. This paper reviews levels, uptake and vegetation response to O3 in Italy over recent years to discuss value, uncertainty and feasibility of different approaches to risk assessment.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 16889878</style></notes></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%">Grossoni, P.</style></author><author><style face="normal" font="default" size="100%">Bussotti, F.</style></author><author><style face="normal" font="default" size="100%">Tani, C.</style></author><author><style face="normal" font="default" size="100%">Gravano, E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Morpho-anatomical aterations in leaves of Fagus sylvatica L. and Quercus ilex L. in different environmental stress condition</style></title><secondary-title><style face="normal" font="default" size="100%">Chemosphere</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Fagus sylvatica</style></keyword><keyword><style  face="normal" font="default" size="100%">foliar structure</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">xeric conditions (voyant)</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1998</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1998///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/pii/S0045653597101485</style></url></web-urls></urls><pages><style face="normal" font="default" size="100%">919 - 924</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">By means of anatomical and foliar structure observations, this paper examines the ecological behaviour of two different species of broadleaf (a mesophile one, beech, and a xerophile one, holm-oak), under different conditions of water supply. The purpose of this study was to evaluate their response in relation to possible climate changes. The results highlight certain similarities of behaviour (reduction of leaf surface, increased leaf thickness, increase of mechanical structures in xeric stands). The main difference between the two species lies in the tannins content, which increase in the epidermal cells (vacuoles and walls) only in beech trees in xeric conditions</style></abstract><issue><style face="normal" font="default" size="100%">5</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%">Bussotti, F.</style></author><author><style face="normal" font="default" size="100%">Ferretti, M.</style></author><author><style face="normal" font="default" size="100%">COZZI, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Crown status of holm oak (Quercus ilex L.) trees as related to phenology and environmental stress</style></title><secondary-title><style face="normal" font="default" size="100%">Water, Air, &amp; Soil …</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">abscission</style></keyword><keyword><style  face="normal" font="default" size="100%">crown condition</style></keyword><keyword><style  face="normal" font="default" size="100%">holm oak (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">leaves</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1995</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1995///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/p7472u8l15164pk6.pdf</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">85</style></volume><pages><style face="normal" font="default" size="100%">1269 - 1274</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In order to study the possible interactions between air pollution and climate coaditions in Mediterranean evergream broadleaf species, since 1987 we have been monitoring the annual and infra-annual variations in crown density of Quercus ilex L. (holm oak) in a permanent sample plot. The behaviour of crown density has been compared with litterfall pattern and aging processes in leaves. The results of this study confirm the important impact of climate on crown condition in Meditea-raneeaa broadleaves, so that even the role of non- acute pollution can be disguised. Xeromorph adaptations in holm oak leaves are also a mechanism providing a greater protection against poltutants.</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%">Bussotti, F.</style></author><author><style face="normal" font="default" size="100%">Grossoni, P.</style></author><author><style face="normal" font="default" size="100%">Pantani, F.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The role of marine salt and surfactants in the decline of tyrrhenian coastal vegetation in Italy</style></title><secondary-title><style face="normal" font="default" size="100%">Annales des Sciences Forestières</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">crown damage</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf absorption</style></keyword><keyword><style  face="normal" font="default" size="100%">marine aerosol</style></keyword><keyword><style  face="normal" font="default" size="100%">NaCl</style></keyword><keyword><style  face="normal" font="default" size="100%">Pinus pinea L</style></keyword><keyword><style  face="normal" font="default" size="100%">surfactant</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1995</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1995///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.afs-journal.org/articles/forest/abs/1995/03/AFS_0003-4312_1995_52_3_ART0006/AFS_0003-4312_1995_52_3_ART0006.html</style></url></web-urls></urls><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The decline of coastal vegetation is a phenomenon affecting some areas of the Mediterranean region and Australia; it is due to the presence of surfactants in marine aerosols, a consequence of sea pollution by detergents. This paper gives some observations made at various sites along the Tyrrhenian coast in Italy. The authors show that the presence of surfactants in the environment correlates with the presence of sea salt, and that the impact of surfactants on vegetation is local and occurs in association with strong sea winds. The study of the synergistic effect of surfactants and sea salt on the crowns of trees exposed to aerosols suggests that the surfactant can cause direct damage, while the absorption of sea salt is enhanced by the presence of the surfactant only when exposure to aerosol is prolonged, or if it is administered in very high concentrations.</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%">Bussotti, F.</style></author><author><style face="normal" font="default" size="100%">BROGI, L.</style></author><author><style face="normal" font="default" size="100%">Grossoni, P.</style></author><author><style face="normal" font="default" size="100%">COZZI, A.</style></author><author><style face="normal" font="default" size="100%">GELLINI, R.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CROWN STRUCTURE MODIFICATIONS IN RELATION TO AIR-POLLUTION</style></title><secondary-title><style face="normal" font="default" size="100%">LANDSCAPE AND URBAN PLANNING</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">crown structure</style></keyword><keyword><style  face="normal" font="default" size="100%">forest formations</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1993</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1993///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">24</style></volume><pages><style face="normal" font="default" size="100%">167 - 173</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Analysis of crown structure and crown modifications plays a role of primary importance in surveys of `new types of forest damage', since it is a decisive parameter in assessing the health status of a tree. Several forms of ramification alterations have been described in central and northern European species (Norway spruce, beech, Durmast oak, English oak, birch). This study examines the situation in Tuscany and offers a description of the alterations found in the main species typical of the Mediterranean region (Turkey oak, pubescent oak, holm oak, stone pine). The article discusses the potential impact of these alterations on the most typical forest formations, the ones which characterize the Tuscan landscape, and it describes the modifications already under way.</style></abstract><issue><style face="normal" font="default" size="100%">1-4</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS&lt;br/&gt;publisher: ELSEVIER SCIENCE BV</style></notes></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%">Clauser, F.</style></author><author><style face="normal" font="default" size="100%">GELLINI, R.</style></author><author><style face="normal" font="default" size="100%">Bussotti, F.</style></author><author><style face="normal" font="default" size="100%">Cenni, E.</style></author><author><style face="normal" font="default" size="100%">Bottacci, A.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">New types of damage to forest trees typical of the Mediterranean region</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Forest Pathology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">crown damage</style></keyword><keyword><style  face="normal" font="default" size="100%">damage</style></keyword><keyword><style  face="normal" font="default" size="100%">decline (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">foliage reduction</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1989</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1989///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1111/j.1439-0329.1989.tb00237.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">78 - 83</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Since 1984 a new type of damage to the typical tree species growing in the mediterranean area has been observed.
