Under such conditions, there is high probability that forests will be subject to increased frequency and intensity of stress due to climatic extremes. Therefore, impacts of climate change on forest health should be carefully evaluated. Given these assumptions, several fungal diseases on trees may become more devastating because of the following factors: (i) abiotic stresses, such as drought and flooding, are known to predispose trees to several pathogens; (ii) temperature and moisture affect pathogen sporulation and dispersal, and changes in climatic conditions are likely to favour certain pathogens; (iii) migration of pathogens triggered by climatic change may increase disease incidence or geographical range, when pathogens encounter new hosts and (or) new potential vectors; and (iv) new threats may appear either because of a change in tree species composition or because of invasive species. If infection success is dependent on temperature, higher mean temperatures may lead to more attacks. Pathogens that have been of importance in southern Europe may spread northward and also upward to mountains. Pathogens with evolutionary potential for greater damage should be identified to estimate the magnitude of the threat and to prepare for the changing conditions. A review of the above-mentioned cases is presented. Some priorities to improve the ability to predict impacts of climate change on tree diseases are discussed.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1080/07060661.2008.10540534</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1080/07060661.2008.10540534</style></research-notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">LUQUE, J</style></author><author><style face="normal" font="default" size="100%">ÁLVAREZ, I</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">PATOGENICIDAD DE HONGOS AISLADOS DEL ALCORNOQUE EN CATALUÑA</style></title><secondary-title><style face="normal" font="default" size="100%">II Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Botryosphaeria stevensii</style></keyword><keyword><style  face="normal" font="default" size="100%">decline</style></keyword><keyword><style  face="normal" font="default" size="100%">Hypoxylon mediterraneum</style></keyword><keyword><style  face="normal" font="default" size="100%">pathogenic fungi</style></keyword><keyword><style  face="normal" font="default" size="100%">phytophthora cinnamomi</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><pub-location><style face="normal" font="default" size="100%">Pamplona</style></pub-location><pages><style face="normal" font="default" size="100%">227-232</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Forty four fungal strains were used in pathogenicity tests made in trunk (32), leaves (8), and roots (8) of cork oak plants (Quereus suber L.) with two irrigation treatments (adequate and stress). Eleven species were found to be pathogenic on tnmk and three on leaf. Trunk pathogens such as Botryosphaeria stevensii, Phytophthora einnamomi, and (?)Diseula sp. caused the death of the inoculated plants. Hydric stress increased both canker and necrosis formation by (?)Diseula sp. and H. mediterraneum, reduced the effects of P. cinnamomi and had no effect on B. stevensii. The latter fungus was a virulent pathogen irrespectively of the irrigation treatment. Dendrophoma myriadea and (?)Fusieoeeum sp. were pathogenic on leaves. Both fungi were negatively affected by the hydric stress. However, no satisfactory results were obtained in the root inoculations. K.W.:</style></abstract></record></records></xml>
