The real&lt;br/&gt;sclerophyllous species, Quercus ilex L., Phillyrea latifolia and&lt;br/&gt;Pistacia lentiscus, showed a convergence in higher leaf thickness and&lt;br/&gt;lower, net photosynthetic rate (PN) compared with Arbutus unedo L. and&lt;br/&gt;Cistus incanus L. Under summer stress they maintained a substantial&lt;br/&gt;positive carbon balance. Pistacia was one of the most tolerant species&lt;br/&gt;to the drought, it maintained a substantial positive balance over a wide&lt;br/&gt;range in temperature. Arbutus and Cistus had relatively thin leaves with&lt;br/&gt;a higher succulence index and higher PN over the more characteristic&lt;br/&gt;sclerophyllous species. The superiority of Cistus in carbon uptake over&lt;br/&gt;all the spacies was maintained throughout most of the year by its&lt;br/&gt;morphological leaf properties. low leaf thickness, high chlorophyll&lt;br/&gt;contents. Besides, Cistus shed most of its leaves before summer, thus&lt;br/&gt;reducing its evaporative surface.</style></abstract></record></records></xml>
