The correlation analysis indicated that LMA variation was tightly associated with LL variations: Cistus incanus and Arbutus unedo had a short LL (4±1, summer leaves, and 11±1 months, respectively) and low LMA (153±19 g m –2 ) values, Quercus ilex, Phillyrea latifolia, and Pistacia lentiscus high LMA (204±7 g m –2 ) and long LL (22±3 months), Erica arborea, Erica multiflora, and Rosmarinus officinalis a short LL (9±2 months) and an either high (213±29 g m –2 , R. officinalis and E. multiflora) or low (115±17 g m –2 , E. arborea) LMA. LMA values were significantly (p≤0.05) correlated with PN (r≥0.68). In the tested species, LMA increased in response to the decrease of the total rainfall during the leaf expansion period. LMA variation was due to the unequal variation of DM and LA in the considered species. LMA is thus a good indicator of evergreen maquis species capability to respond to climate change, in particular to total rainfall decrease in the Mediterranean basin.</style></abstract></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%">Gratani, L</style></author><author><style face="normal" font="default" size="100%">Bombelli, A</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Visconti, G and Beniston, M and Iannorelli, ED and Barba, D</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Forecasted stability of Mediterranean evergreen species considering global changes</style></title><secondary-title><style face="normal" font="default" size="100%">GLOBAL CHANGE AND PROTECTED AREAS</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">C. incanus</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf life span</style></keyword><keyword><style  face="normal" font="default" size="100%">P. latifolia</style></keyword><keyword><style  face="normal" font="default" size="100%">Q. ilex</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2001</style></year></dates><publisher><style face="normal" font="default" size="100%">SPRINGER</style></publisher><pub-location><style face="normal" font="default" size="100%">PO BOX 17, 3300 AA DORDRECHT, NETHERLANDS</style></pub-location><volume><style face="normal" font="default" size="100%">9</style></volume><pages><style face="normal" font="default" size="100%">245-252</style></pages><isbn><style face="normal" font="default" size="100%">0-7923-6918-1</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Plant communities of the Mediterranean climate Regions are exposed to&lt;br/&gt;high temperatures, high radiation and water stress during summer, they&lt;br/&gt;are dominated by evergreen sclerophyllous species and drought semi&lt;br/&gt;deciduous species. To define the adaptive strategies, anatomical and&lt;br/&gt;morphological leaf traits of Quercus ilex L., Phillyrea latifolia L.&lt;br/&gt;(typical evergreen sclerophyllous species) and Cistus incanus L., (a&lt;br/&gt;drought semi deciduous species), growing in the Mediterranean maquis&lt;br/&gt;along Pome's coast line (Italy) were analysed. The typical evergreen&lt;br/&gt;sclerophyllous species have long leaf life span (from 1 to 4 years),&lt;br/&gt;steeper leaf inclination (average 56 degrees), higher specific leaf mass&lt;br/&gt;(average 21.3 mg cm(-2)) and the highest leaf thickness (average 324&lt;br/&gt;mum). The semi deciduous species have a lower leaf life span (from 4 to&lt;br/&gt;8 months), a lower leaf inclination (44 degrees +/- 13 degrees), a lower&lt;br/&gt;specific leaf mass (14.7 +/-1.5 mg cm(-2)) and a lower leaf thickness&lt;br/&gt;(244 +/- 15 mum). The more xeromorphyc species (Q. ilex and P.&lt;br/&gt;latifolia) may be at a competitive advantage considering the forecasted&lt;br/&gt;air temperature increase in the Mediterranean basin. Increasing drought&lt;br/&gt;stress may in fact determine a shortening of leaf life span that may&lt;br/&gt;prove to be critical for C. incanus. Knowledge of plant response to&lt;br/&gt;stress factors is important in the perspective of climatic changes.</style></abstract><notes><style face="normal" font="default" size="100%">Meeting on Global Change and Protected Areas, LAQUILA, ITALY, SEP, 1999</style></notes><research-notes><style face="normal" font="default" size="100%">Meeting on Global Change and Protected Areas, LAQUILA, ITALY, SEP, 1999</style></research-notes></record></records></xml>
