The species &lt;e1&gt;Q&lt;/e1&gt;uercus ilex L&lt;e1&gt;.&lt;/e1&gt; (holm oak), an evergreen oak, has been studied through ecophysiological measurements performed in the field and Landsat TM images relating to the Rome metropolitan area. The results obtained show a greater degree of structural and functional alteration in individual holm oaks within the urban area compared with those in the protected areas outside of the central zone. In particular, in 1993 the main stress factor for vegetation is attributable to climatic conditions, whereas in 1998 ozone atmospheric concentration caused an evident alteration of the parameters studied</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%">Seufert, G</style></author><author><style face="normal" font="default" size="100%">Bartzis, J</style></author><author><style face="normal" font="default" size="100%">Bomboi, T</style></author><author><style face="normal" font="default" size="100%">Ciccioli, P</style></author><author><style face="normal" font="default" size="100%">Cieslik, S</style></author><author><style face="normal" font="default" size="100%">Dlugi, R</style></author><author><style face="normal" font="default" size="100%">Foster, P</style></author><author><style face="normal" font="default" size="100%">Hewitt, C N</style></author><author><style face="normal" font="default" size="100%">Kesselmeier, J</style></author><author><style face="normal" font="default" size="100%">Kotzias, D</style></author><author><style face="normal" font="default" size="100%">Lenz, R</style></author><author><style face="normal" font="default" size="100%">Manes, F</style></author><author><style face="normal" font="default" size="100%">Pastor, R.Perez</style></author><author><style face="normal" font="default" size="100%">Steinbrecher, R</style></author><author><style face="normal" font="default" size="100%">Torres, L</style></author><author><style face="normal" font="default" size="100%">Valentini, R</style></author><author><style face="normal" font="default" size="100%">Versino, B</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">An overview of the Castelporziano experiments</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%">air chemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">Biogenic emission</style></keyword><keyword><style  face="normal" font="default" size="100%">ecophysiology</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean area</style></keyword><keyword><style  face="normal" font="default" size="100%">micrometeorology</style></keyword><keyword><style  face="normal" font="default" size="100%">Vegetation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><volume><style face="normal" font="default" size="100%">31, Supple</style></volume><pages><style face="normal" font="default" size="100%">5-17</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper reviews the major outcomes of the measuring campaigns performed at the Castelporziano nature preserve near Rome, Italy, by 14 European laboratories as part of the BEMA (Biogenic Emissions in the Mediterranean Area)-project. Six campaigns of 1–4 weeks duration were carried out in different seasons of the years 1993–1994 at semi-continuously running test plots in the nature reserve, representing common Mediterranean vegetation types. The aim was to characterise, at the different test plots, the atmospheric chemical and meteorological situations, the plant biomass and physiology, the type, amount and controls of emissions from different plants by means of branch enclosures, and the BVOC emission fluxes from different ecosystems, by scaling up enclosure data from individual sources, and by measuring fluxes directly by use of micrometeorological methods. An important focus during the initial phase of the five year BEMA-project was the harmonisation and improvement of the analytical, physiological and micrometeorological methods used, and the development and testing of new methods for measuring BVOC fluxes.</style></abstract></record></records></xml>
