Phytosociological analysis of the <i>Genista</i> sp. pl. garrigues of the <i>Cisto-Lavanduletea</i> and <i>Rosmarinetea officinalis</i> classes in the South-Tyrrhenian area (Mediterranean Region)
收藏资源简介:
The study reviews the <i>Genista</i> sp. pl. garrigues ascribable to the classes <i>Cisto-Lavanduletea</i> (acidophilous communities on volcanics and quartzarenites) and <i>Rosmarinetea officinalis</i> (basiphilous communities on calcareous and calcareous-dolomite substrates), in the southern territories of the Italo-Tyrrhenian Province. The floristic-synecological characterization of the identified coenoses led to the description and/or redefinition of various new syntaxa. They are distributed in the two new suballiances <i>Calicotomo villosae–Genistenion tyrrhenae</i> and <i>Genisto aristatae–Calicotomenion infestae</i> of the class <i>Cisto-Lavanduletea</i> (<i>Lavanduletalia stoechadis</i> and <i>Calicotomo villosae–Genistion tyrrhenae</i>), and in the alliance <i>Cisto eriocephali–Ericion multiflorae</i> of the class <i>Rosmarinetea officinalis</i> (<i>Rosmarinetalia officinalis</i>), with two new described associations.
本研究梳理了意大利-第勒尼安省(Italo-Tyrrhenian Province)南部区域内,可归属于岩蔷薇-薰衣草群丛纲(*Cisto-Lavanduletea*,涵盖火山岩与石英岩基质上的嗜酸植物群落)以及迷迭香群丛纲(*Rosmarinetea officinalis*,涵盖石灰岩与石灰质白云岩基质上的喜钙植物群落)的金雀儿属(*Genista*)多种类加里哥宇群落(garrigues)。通过对所鉴定的植物群落(coenoses)开展区系-群落学特征表征,本研究完成了多个全新群落分类单元(syntaxa)的描述与/或重新界定。这些群落分类单元分别分布于岩蔷薇-薰衣草群丛纲下的两个新亚联盟:糙萼石楠-第勒尼安金雀儿群丛亚联盟(*Calicotomo villosae–Genistenion tyrrhenae*)与芒尖金雀儿-害状石楠群丛亚联盟(*Genisto aristatae–Calicotomenion infestae*),二者隶属于薰衣草群丛目(*Lavanduletalia stoechadis*)以及糙萼石楠-第勒尼安金雀儿群丛联盟(*Calicotomo villosae–Genistion tyrrhenae*);同时还分布于迷迭香群丛纲下的绵毛岩蔷薇-多花欧石楠群丛联盟(*Cisto eriocephali–Ericion multiflorae*),该联盟隶属于迷迭香群丛目(*Rosmarinetalia officinalis*),且该类群中包含两个新描述的群丛(associations)。
