It consists mainly of mosses, 50 to 58% of which are found only&lt;br/&gt;in the soil. Among these, the presence of oligotrophic species of open&lt;br/&gt;habitats (Trichostomum brachydontium, Philonotis arnellii, Funaria grex&lt;br/&gt;muehlenbergii and the liverwort Riccia sorocarpa) that occur below&lt;br/&gt;ground in the Quercus ilex forest is remarkable, whereas soil cores from&lt;br/&gt;the,garrigue and the lawn have given Bryum radiculosum and&lt;br/&gt;Pseudocrossidium hornschuchianum which, like the 4 preceding taxa, are&lt;br/&gt;lacking in the above ground inventories (surface: 100 m(2)) carried out&lt;br/&gt;on the site in the holm oak ecosystem. Our results confirm that the&lt;br/&gt;proportion of acrocarpous mosses belonging to the colonist life strategy&lt;br/&gt;tends to be more important below than above ground, whereas the reverse&lt;br/&gt;is true for pleurocarpous perennials. There is also an increase in the&lt;br/&gt;percentage of colonists present in the soil, when passing from the&lt;br/&gt;forest to the garrigue and the lawn.</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%">Bonin, G</style></author><author><style face="normal" font="default" size="100%">Aubert, G</style></author><author><style face="normal" font="default" size="100%">Barbero, M</style></author><author><style face="normal" font="default" size="100%">Gamisans, J</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Mise en évidence de la dynamique de quelques écosystèmes forestiers et préforestiers provençaux aux étages méditerranéens SL à l'aide des taxons indicateurs</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Analyse des correspondances</style></keyword><keyword><style  face="normal" font="default" size="100%">Ecosyst~mes forestiers</style></keyword><keyword><style  face="normal" font="default" size="100%">France</style></keyword><keyword><style  face="normal" font="default" size="100%">Provence</style></keyword><keyword><style  face="normal" font="default" size="100%">Successions dynamiques</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1983</style></year></dates><volume><style face="normal" font="default" size="100%">54</style></volume><pages><style face="normal" font="default" size="100%">79-96</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Evidence is presented for dynamic successions in the Provence on the basis of a multivariate analysis, of a very large sample. Different phases in the Quercus suber series on silicious substrate are shown. Also the evolution of the vegetation groupings on Ventoux and Sainte-Baume mountains on calcareous substrate and at different levels in the zonation is specified. The succession of the grasslands is as follows: Isoetes and Nasturtium groupings, Serapias, Lotus and Trifolium, then Vulpia and Aira groupings, and finally Helianthemum guttatum grasslands, preceding the shrub groupings: Cistus ladaniferus, then Cistus albidus and Cistus monspeliensis. Then follow either Erica and Calluna maquis or Quercus suber formations. On Mont Ventoux, the stages of degradation of the Quercus pubescens forests are Aphyllantes and Thymus vulgaris grasslands, and Buxus sempervirens and Genista scorpius scrubs. On the oromediterranean level, the transition from Avena setacea and Galium villarsii grasslands, then Ononis caenisia grasslands to Pinus uncinata forests is demonstrated. The development of reforestation is predicted on the basis of the floristic composition of the previous stages. On Sainte-Baume Mountain, the Quercuspubescens supramediterranean series is formed by the following stages: low scrubs of the Lavandulo-Astragaletum, and Prunus mahaleb and Phillyrea media, Acer monspes- sulanum groves, and forests with prevailing Quercuspubescens. The succession on rocky traverses and crests is slightly different. The first stages are Sesleria grasslands and the later ones are woodland groupings of Tilia platyphyllos, Acer opalus and llex aquifolium.</style></abstract></record></records></xml>
