Decrit en 1844 (J. turbinata Guss.), il sera longtemps oublie de nombreuses flores et checklists jusqu’a une date tres recente malgre des travaux de morphologie et de phytochimie qui, des les annees 1980, vont confirmer son individualite taxonomique. Les conclusions des etudes moleculaires recentes vont aussi dans ce sens. Le present travail precise sa chorologie, aussi bien dans sa globalite que par pays ou secteurs geographiques, permettant de dresser une carte de repartition mondiale actualisee. Une carte supplementaire illustre la repartition des deux autres taxons du groupe («J. phoenicea » et «J. canariensis » ). Les aspects concernant la caryologie, la biologie de la reproduction et les interactions biologiques sont abordes, de meme que son ecologie, ce qui permet de dresser un tableau recapitulatif des principaux groupements phytosociologiques jusqu’au niveau de l’alliance dans lesquels il s’insere ou intervient. Un focus particulier permet de s’interesser aux menaces et a sa conservation. Enfin, une rapide discussion sur la taxonomie complexe des genevriers rouges permet de justifier le traitement retenu dans ce travail pour les taxons du groupe de J. phoenicea selon trois sous-especes, en validant une nouvelle combinaison nomenclaturale et en proposant une cle de determination des taxons infraspecifiques. Ainsi, Juniperus phoenicea L. subsp. turbinata (Guss.) Nyman doit etre considere comme un taxon circummediterraneen remarquable souvent en danger ou en regression dans son aire de repartition, qui s’etend le long du littoral mediterraneen depuis le sud du Portugal et le Maroc jusqu’en Mediterranee orientale (grandes iles comprises), en passant par les hautes montagnes continentales d’Afrique du Nord, puis debordant jusqu’en Arabie Saoudite.

L’etude a ete menee sur des carrieres alluvionnaires seches de la plaine de la Crau (sud-est de la France), exploitees dans les annees 1970- 1980 et qui ont detruit l’ecosysteme de pelouses seches mediterraneennes dont la majorite de la surface est actuellement strictement protegee (le reste etant classe en Natura 2000).

EnglishThis study aims to evaluate the ecological potentials of quarries after exploitation and their contribution to regional biodiversity in their eco-landscape context. To do so, an ecological diagnosis was established. It was based on mapping the neoformed habitats on the old extraction sites and on carrying out a systematic inventory of animal species (birdlife, herpeto-fauna, etc.) and plants with high heritage value. The study was done on the dry alluvial quarries of the plain of La Crau (South-eastern of France), exploited in the years 1970-1980 and which destroyed the ecosystem of Mediterranean dry grasslands currently strictly protected. After exploitation, quarries were the subject of a great diversity of ecological restorative activities (ecological rehabilitation, lack of rehabilitation, deposits of anthropogenic materials, etc.). The results show that the old quarries are home to mosaics of habitats that host diverse animal groups and plant species and thus form numerous refuges for rare and endangered species. And even if the plant and animal groups diverge from the reference ecosystem, they can be interesting from the point of view of biodiversity. Finally, these results linked to the poor success of other ecological restoration projects of the same ecosystem can lead to a parad","PeriodicalId":37547,"journal":{"name":"Ecologia Mediterranea","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70185761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
