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%">Hebrard, J P</style></author><author><style face="normal" font="default" size="100%">Loisel, R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Search for factors maintaining terricolous bryoflora richness in isolated habitats .2.

The confrontation of the bryofloristical and the station data shows that ambient humidity and substratum richness in total nitrogen play an important role in the differenciation of terricolous bryophyte communities. Two forest sets, one humid and rich in nitrogen of organic origin (ubac of Defens du Becasson : surface = 77617 m(2), scrub-layer dense), the other dry and poor in that element (isolates and hedges with a surface less than or equal to 13115 m(2), scrub-layer absent) have been defined whereas a third, very xeric set, groups nearly all releves from the contact zone i, where supply in nitrate fertilizer may be important.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></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%">Hebrard, J P</style></author><author><style face="normal" font="default" size="100%">Loisel, R</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">SEARCH FOR FACTORS MAINTAINING TERRICOLOUS BRYOFLORA RICHNESS IN ISOLATED HABITATS - THE CASE OF SCLEROPHYLLOUS OAK GROVES OF THE OCCIDENTAL BORDER OF THE MAURES MASSIF (VAR, FRANCE)</style></title><secondary-title><style face="normal" font="default" size="100%">CRYPTOGAMIE BRYOLOGIE LICHENOLOGIE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">bryophytes</style></keyword><keyword><style  face="normal" font="default" size="100%">Microhabitats</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></keywords><dates><year><style  face="normal" font="default" size="100%">1994</style></year></dates><publisher><style face="normal" font="default" size="100%">ADAC-CRYPTOGAMIE</style></publisher><pub-location><style face="normal" font="default" size="100%">12 RUE DE BUFFON, 75005 PARIS, FRANCE</style></pub-location><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">267-290</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Processing (FAC) of 25 bryophytoecological releves and quantitative analysis of bryofloristical inventories from 4 forest structures (surface values respectively 3976, 6160, 13115 and 77617 m2) isolated within the vineyard near Pierrefeu-du-Var (siliceous substratum) show that, for what concerns sclerophyllous oaks ecosystems (Quercus ilex, more rarely Quercus suber), the more humid the local microclimate is, the greatest are richness and diversity of terricolous communities of bryophytes. The optimal conditions for preservation of richness in forest bryophytes are here realized at the Defens du Becasson (surface: 77617 m2, maximum width: 151 m), a north-facing side which is well protected against the drying action of dominant winds and where the architecture of the ligneous formations is heterogeneous. On the other hand, the diversity of available microhabitants in the 2 largest isolates (strong slope, presence of clearings and disturbed skirts) contributes to increase their global richness in bryophytes. Furthermore, the presence of a dense layer of shrubs limits the accumulation of dead leaves on soil surface, allowing a good spread of the bryophyte layer and correlatively an enrichment in forest taxa when ambient humidity is high enough.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></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%">Hebrard, J P</style></author><author><style face="normal" font="default" size="100%">ROUX, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">COLOLEJEUNEA-MINUTISSIMA (SM) SCHIFFN IN THE HOLM OAK GROVE OF PORT-CROS ISLAND (ILES DHYERES, VAR, FRANCE)</style></title><secondary-title><style face="normal" font="default" size="100%">NOVA HEDWIGIA</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cololejeunea minutissima</style></keyword><keyword><style  face="normal" font="default" size="100%">Holm oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1991</style></year></dates><publisher><style face="normal" font="default" size="100%">GEBRUDER BORNTRAEGER</style></publisher><pub-location><style face="normal" font="default" size="100%">JOHANNESSTR 3A, D-70176 STUTTGART, GERMANY</style></pub-location><volume><style face="normal" font="default" size="100%">53</style></volume><pages><style face="normal" font="default" size="100%">423-431</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Discovery of Cololejeunea minutissima (Sm.)
