A key, but frequently overlooked, component of these systems is the fungal community associated with the dominant oaks. We present a study of the basidiomycete community in montado areas of Quercus suber L. from Central-Western Portugal, based on fruiting body assessment and PCR-DGGE of soil mycelium. Soil available phosphorus and organic matter content were also determined. The most frequent fruiting body found in the cork oak montados belonged to Lactarius, Clitocybe, Russula and Cortinarius species. Lactarius chrysorrheus was the most widely distributed species. Soil management practices cause a temporal increase in soil available phosphorus, and harrowing and fertilizer application also result in an increase in soil organic matter content. Mechanical clearing with recent soil disturbance had a negative effect on the richness and diversity of the basidiomycete community assessed using fruiting body. The molecular analysis of the basidiomycete community separated the sites with recent shrub-removal from the others sites. Our results show that soil management techniques that avoid disturbance of the top-soil layers are the best way to preserve the structure and diversity of the soil fungal community in the montado.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier Masson SAS</style></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%">Buscardo, Erika</style></author><author><style face="normal" font="default" size="100%">Rodríguez-Echeverría, Susana</style></author><author><style face="normal" font="default" size="100%">Martín, María P.</style></author><author><style face="normal" font="default" size="100%">De Angelis, Paolo</style></author><author><style face="normal" font="default" size="100%">Pereira, João Santos</style></author><author><style face="normal" font="default" size="100%">Freitas, Helena</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Impact of wildfire return interval on the ectomycorrhizal resistant propagules communities of a Mediterranean open forest.</style></title><secondary-title><style face="normal" font="default" size="100%">Fungal biology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ectomycorrhizal resistant propagules community</style></keyword><keyword><style  face="normal" font="default" size="100%">Fire return interval</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean ecosystem</style></keyword><keyword><style  face="normal" font="default" size="100%">Pinus pinaster (maritime pine)</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber (cork oak)</style></keyword><keyword><style  face="normal" font="default" size="100%">succession</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.ncbi.nlm.nih.gov/pubmed/20943174</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">114</style></volume><pages><style face="normal" font="default" size="100%">628 - 636</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Ectomycorrhizal (ECM) fungi, in particular their spores and other resistant propagules, play an important role in secondary succession processes that facilitate regeneration after disturbance events. In this study, the effects of high and low wildfire frequencies (respectively short and long fire return intervals) on the resistant propagules communities (RPCs) of a Mediterranean open pine forest were compared. Soil samples were collected in four mountain sites with different fire return intervals and used to test ectomycorrhiza development in two hosts, Pinus pinaster and Quercus suber. RPCs were characterized by direct sequencing of fungal internal transcribed spacer (ITS) regions from individual ECM root tips. Eighteen ECM species were detected in the bioassay. The most frequently found fungi were Cenococcum geophilum, Inocybe jacobi, Thelephora terrestris, Tomentella ellisii on both hosts and Rhizopogon luteolus and R. roseolus on maritime pine. A short fire return interval reduced the species richness of the ECM community found on Q. suber, promoted species like R. roseolus and reduced the abundance of other species (e.g. R. luteolus). The abundance of I. jacobi was positively affected by long fire return interval, but decreased significantly with recurrent fires. These results indicate that changes in fire frequency can alter the structure, composition and diversity of ECM communities, which could compromise the resilience of the ecosystem in highly disturbed areas.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 20943174</style></notes></record></records></xml>
