Foliage transparency, leaf damage and crown dieback have changed significantly over the monitoring period. Leaf area, length of the current year shoots, and total leaf area changed as well, but only for Turkey oak. Changes were consistent between and within the plots. Different indices of plant diversity showed marked changes, apparently linked to natural dynamics within individual ecosystems. These rapid and contrasting fluctuations in the various indicators of forest ecosystem make it difficult to derive a synthesis about the general condition of ecosystems and - especially - about the effects of air pollution.</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%">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></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><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.
