We investigated the discriminatory power of a subset of highly variable proposed plant barcoding loci (matK, trnH-psbA, ITS2) in Quercus, a taxonomically complex tree genus of global importance. The research included all currently recognized species and some major variants of the Mediterranean region and Europe (32 taxa) and 17 East Asian and North American species used for comparison. Based on sequence character state, we assigned unique plastid haplotypes to 40.8% of the investigated species; ITS2 increased the resolution up to 87.8% of total taxa. Nevertheless, unsuccessful genetic distance-based discrimination questioned the potential efficiency of correct species identification for future studies. Most species appeared to be nonmonophyletic in parallel phylogenetic tests. Three subgeneric groups were outlined, with different rates of within-group variability and geographical differentiation. Members of one of these groups (corresponding to the Eurasian Group Ilex) were paraphyletic to Group Quercus from the New and Old World and the Eurasian Group Cerris. The data gathered indicate that barcoding markers may help to identify closely related species clusters and contribute to the inference of major diversification and evolutionary patterns in oaks, but the methodology per se appears to be of limited efficacy in defining species limits, unless we make a profound revision of traditional Quercus taxonomic categories. © 2013 The Linnean Society of London, Botanical Journal of the Linnean Society, 2013, 00, 000–000.</style></abstract></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%">Petroselli, Andrea</style></author><author><style face="normal" font="default" size="100%">Vessella, Federico</style></author><author><style face="normal" font="default" size="100%">Cavagnuolo, Lucia</style></author><author><style face="normal" font="default" size="100%">Piovesan, Gianluca</style></author><author><style face="normal" font="default" size="100%">Schirone, Bartolomeo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Ecological behavior of Quercus suber and Quercus ilex inferred by topographic wetness index (TWI)</style></title><secondary-title><style face="normal" font="default" size="100%">Trees</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ecological gradients</style></keyword><keyword><style  face="normal" font="default" size="100%">Forest ecology</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword><keyword><style  face="normal" font="default" size="100%">Terrain analysis</style></keyword><keyword><style  face="normal" font="default" size="100%">Topographic wetness index</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><publisher><style face="normal" font="default" size="100%">Springer Berlin Heidelberg</style></publisher><volume><style face="normal" font="default" size="100%">27</style></volume><pages><style face="normal" font="default" size="100%">1201-1215</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The ecological behaviors of a network of pure evergreen oak stands (Quercus suber L. and Quercus ilex L.) in the Central-Western Mediterranean Basin were investigated toward climatic and edaphic factors implemented with the application of topographic wetness index (TWI). A Categorical Principal Component Analysis (Catpca) using climatic and soil physico-chemical parameters was performed on 23 cork oak and holm oak pure stands with the aim to understand better the effectiveness of TWI for characterizing soil ecology of the two species. Catpca pointed out that, although cork oak and holm oak are able to growth in similar Mediterranean conditions, they show different behaviors in terms of needs and tolerance to soil water content. TWI confirmed such results at local scale, allowing highlighting some interesting features of the species differential ecology. Although both species confirmed to be drought-tolerant, the heliophilous cork oak revealed to dominate the landscape on wettest soils with high TWI values-indicating the capacity to tolerate stresses due to periods of waterlogging-, while the shade-tolerant holm oak prevails for low-medium TWI values-drier and mesophilous sites. Despite the application of TWI to vegetation science and ecology is relatively recent, results are encouraging and suggest considering this user-friendly and synthetic index in ecological investigations and modeling.</style></abstract></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%">Vessella, Federico</style></author><author><style face="normal" font="default" size="100%">Schirone, Bartolomeo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Predicting potential distribution of Quercus suber in Italy based on ecological niche models: Conservation insights and reforestation involvements</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Ecology and Management</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Conservation and reforestation areas</style></keyword><keyword><style  face="normal" font="default" size="100%">Distribution patterns</style></keyword><keyword><style  face="normal" font="default" size="100%">GARP</style></keyword><keyword><style  face="normal" font="default" size="100%">Maxent</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier B.V.</style></publisher><volume><style face="normal" font="default" size="100%">304</style></volume><pages><style face="normal" font="default" size="100%">150-161</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Different statistical techniques have been used to model species potential distribution related to environ- mental variables. This paper provides a comprehensive assessments of GARP and MaxEnt methods, and investigates for the first time the probability of occurrence of cork oak (Quercus suber L.) in Italy based on ecological niche modelling approaches. A detailed distribution of the species was achieved during a 3- year National Project (SuberItalia) and 17 environmental layers were employed to obtain the potential distribution of cork oak. The performance of the models were measured using the receiver operating characteristic (ROC) approach and Cohen’s Kappa statistic. Results achieved by GARP and MaxEnt showed as the drought and the cold stresses are the main factors affecting cork oak occurrence in Italy. Moreover, the accuracy of the obtained prediction maps were compared to a specifically calibrated geo-statistical method at regional scale, pointing out a preliminary geographical assessment of the suitable surfaces to set apart for cork oak forest expansion in Italy, thereby useful to address reforestation and conserva- tion concerns to face the ongoing area reduction of these forests.</style></abstract></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%">Schirone, Bartolomeo</style></author><author><style face="normal" font="default" size="100%">Salis, Antonello</style></author><author><style face="normal" font="default" size="100%">Vessella, Federico</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effectiveness of the Miyawaki method in Mediterranean forest restoration programs</style></title><secondary-title><style face="normal" font="default" size="100%">Landscape and Ecological Engineering</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">ecological restoration</style></keyword><keyword><style  face="normal" font="default" size="100%">ecotechnology</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean environment</style></keyword><keyword><style  face="normal" font="default" size="100%">potential natural vegetation</style></keyword><keyword><style  face="normal" font="default" size="100%">reforestation practices comparison</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s11355-010-0117-0</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">7</style></volume><pages><style face="normal" font="default" size="100%">81 - 92</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the 1980s, Professor Akira Miyawaki introduced a new and innovative reforestation approach in Japan with the challenge to restore indigenous ecosystems, and maintaining global environments, including disaster prevention and carbon dioxide (CO2 ) mitigation. Here, natural vegetation successional stages (from bare soil to mature forest) are practically forced and reproduced, accelerating natural successional times. The Miyawaki method has been applied in the Far East, Malaysia, and South America; results have been very impressive, allowing quick environmental restorations of strongly degraded areas. However, these applications have always been made on sites characterized by high precipitation. The same method has never been used in a Mediterranean context distinguished by summer aridity and risk of desertiﬁcation. A ﬁrst test was carried out by the University of Tuscia, Department of Forest and Environment (DAF), 11 years ago in Sardinia (Italy) on an area where traditional reforestation methods had failed. For an appropriate Miyawaki application on this site, the original method was modiﬁed while maintaining its theoretical principles. Results obtained 2 and 11 years after planting are positive: having compared the traditional reforestation techniques, plant biodiversity using the Miyawaki method appears very high, and the new coenosis (plant community) was able to evolve without further operative support after planting. Therefore, the implementation of supplementary technique along with cost reduction might provide a new and innovative tool to foresters and ecological engineering experts for Mediterranean environmental reforestation program.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
