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.
