Other features of these inner areas (whose bottom is about 300–400 m) are the high annual temperature range of about 18°–20°C, and the quite low rate of rainfall (often below 700mm; below 500mm at Capestrano) because of the mountains which stop the wet winds.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">ENTOMOLOGICAL ASPECTS OF THE PROTECTION OF QUERCUS-SUBER L FORESTS IN SARDINIA</style></title><secondary-title><style face="normal" font="default" size="100%">RESPONSES OF FOREST ECOSYSTEMS TO ENVIRONMENTAL CHANGES</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER APPL SCI PUBL LTD</style></publisher><pub-location><style face="normal" font="default" size="100%">BARKING ESSEX</style></pub-location><pages><style face="normal" font="default" size="100%">972-973</style></pages><isbn><style face="normal" font="default" size="100%">1-85166-878-0</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the Sardinian cork oak forests, more than 300 species of Lepidoptera have been found, 10% of which develop on Quercus suber L. trees. The population density of these insects varies greatly, and, in some cases, is so high that causes total defoliation on large scale. Three species in particular cause serious damage: Lymantria dispar L., and Malacosoma neustria L. with periodic infestations and Tortrix viridana L. with temporary ones. There are also other, less harmful species, such as Dryobota labecula Esp., Dryobotodes monochroma Esp., Dryobotodes eremita Fabr., Orthosia cruda Den. &amp; Schiff., Spudaea ruticilla Esp. and Phalera bucephala (L.) that have different fluctuations which can be described as latent or periodic (3).</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">GROWTH-PATTERN AND ARCHITECTURE IN QUERCUS-ILEX L AND FRAXINUS-ORNUS L VEGETATIVE REGENERATION AFTER COPPICING IN MAREMMA-NATURE-PARK (CENTRAL ITALY)</style></title><secondary-title><style face="normal" font="default" size="100%">RESPONSES OF FOREST ECOSYSTEMS TO ENVIRONMENTAL CHANGES</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER APPL SCI PUBL LTD</style></publisher><pub-location><style face="normal" font="default" size="100%">BARKING ESSEX</style></pub-location><pages><style face="normal" font="default" size="100%">993-994</style></pages><isbn><style face="normal" font="default" size="100%">1-85166-878-0</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Growth pattern and architecture have been studied in Quercus ilex L. and Fraxinus ornus L. stools as main phenomena, testing the space occupation dynamics by the new population of shoots after coppicing.

Two of the questions we sought to answer were (i) in the case where the same disturbance persists, whether these coppice stands reach a state of “equilibrium” based on auto-succession or they continue to change, and (ii) in the case where disturbance stops, whether the present dominant species (Q. ilex or C. sativa) continues to be dominant (high resilience) or an other species (Q. pubescens ?) could replace it. A third case exists, i.e. a change of the “disturbance” in order to obtain a “sustainable” development, but, in that case, biological or socio-economical criteria must be defined. In order to highlight the first stages of these possible changes, germination abilities of these species were studied and compared. For Q. ilex coppice stands, it can be said that there would appear to be a partial allelopathic inhibition of Q. ilex germination, to which Q. pubescens is less sensitive. For C. sativa, this phenomenon was not found. We also briefly discuss the main characteristics of a programme which tests some biological criteria for a sustainable development.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors></contributors><titles><title><style face="normal" font="default" size="100%">QUERCUS-ILEX L LITTER DECOMPOSITION AND MINERAL EVOLUTION IN AN EVERGREEN OAK WOODLAND IN MAJORCA (BALEARIC-ISLANDS, SPAIN)</style></title><secondary-title><style face="normal" font="default" size="100%">RESPONSES OF FOREST ECOSYSTEMS TO ENVIRONMENTAL CHANGES</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER APPL SCI PUBL LTD</style></publisher><pub-location><style face="normal" font="default" size="100%">BARKING ESSEX</style></pub-location><pages><style face="normal" font="default" size="100%">865-866</style></pages><isbn><style face="normal" font="default" size="100%">1-85166-878-0</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this contribution is to describe the decomposition processes of litter in an evergreen oak wood and the evolution of the four cations; calcium, magnesium, sodium and potassium.</style></abstract></record></records></xml>
