Despite the fact that cork oak is distributed over about 1.7 million hectares in the western Mediterranean Basin, information about soil biota in this particular habitat at present is scanty. This study was carried out in a cork tree wood in Bergeggi (Liguria, NW Italy), characterized by a Pluvioseasonal Oceanic Mediterranean bioclimate. The profile, texture, pH, total carbonate content, total organic carbon (C) and nitrogen (N) contents, soluble phosphorus (P) and cation exchange capacity were measured in order to characterize the soil. Soil biological quality was evaluated by studying microarthropod communities. Each month, from February 2007 to January 2008, 10 soil samples measuring 10 ? 10 ? 10 cm were collected from the wood being studied and arthropods were extracted using Berlese-Tullgren funnels. The biological quality of soil based on arthropods (QBS-ar) index, taxa abundance, Shannon diversity index (H?) and Pielou?s evenness index (J) were applied to assess soil biological quality in the cork oak being studied. A total of 29 taxonomic groups were identified. Some important groups, such as Pseudoscorpionida, Palpigradi, Miriapoda and Protura were detected every month, but only a few groups showed a clear abundance distribution trend throughout the year and globally it was impossible to define general trends. The results suggested that the condition of the soil was good, as generally observed in natural environments not subjected to significant impacts. It was also possible to demonstrate that the Mediterranean climate causes strong seasonal fluctuations in soil biota, resulting in corresponding differences in the QBS-ar index values. Therefore, the QBS-ar index could be considered to be a valid candidate for the biomonitoring of soil biodiversity in natural and anthropic soils, but in Mediterranean climates comparisons of different areas must be performed analyzing samples collected during the same period.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">From Duplicate 2 (Is the QBS-ar index a good tool to detect the soil quality in Mediterranean areas?

In order to study changes in these properties, five plots were established; three plots in mature natural site dominated by Pinus pinaster and Quercus ilex and two plots post-wildfire natural regeneration site dominated by Quercus ilex. In each site, a silviculture treatment of thinning had been previously carried out, while the other was left as a forest control. Soil samples were taken during the dry season (July 2010) and after the first autumn rains (October 2010). The experiment consisted on a nested factorial design with two factors: the site (two levels: mature natural and regenerated) and thinning treatment nested within site effect (three levels in mature natural site: control, thinned in 2002 and thinned in 2004, and two levels within regenerated site: control and thinned in 2008).Several sensitive variables related to the soil microbial activity such as soil respiration and biomass carbon and some enzyme activities (urease, phosphatase, β-glucosidase and dehydrogenase) were evaluated. Physical and chemical soil variables (organic matter, total nitrogen, phosphorus, pH, conductivity and carbonates) were also measured. These variables of forest soil in autumn were highest that in summer. Also the results showed that thinning have a significant effect on soil microbiological variables and soil enzymatic activities. Thinning operations tended to alter soil variables and highly reduced the organic matter content. A significant correlation was also found between microbiological and biochemical variables and physic chemical variables, organic matter and total nitrogen. Adaptative management forest plans should consider these results in order to achieve sustainable forest management, especially in the context of soil quality and Mediterranean forest subjected to wildfire disturbances.</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%">Mariscal-Sancho, Ignacio</style></author><author><style face="normal" font="default" size="100%">Peregrina, Fernando</style></author><author><style face="normal" font="default" size="100%">Mendiola, Maria A</style></author><author><style face="normal" font="default" size="100%">Santano, Jesus</style></author><author><style face="normal" font="default" size="100%">Espejo, Rafael</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Exchange Complex Composition in Mediterranean Ultisols Under Various Types of Vegetation and Soil Uses</style></title><secondary-title><style face="normal" font="default" size="100%">SOIL SCIENCE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">organic carbon</style></keyword><keyword><style  face="normal" font="default" size="100%">Soil degradation</style></keyword><keyword><style  face="normal" font="default" size="100%">soil quality</style></keyword><keyword><style  face="normal" font="default" size="100%">storage bases</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><publisher><style face="normal" font="default" size="100%">LIPPINCOTT WILLIAMS &amp; WILKINS</style></publisher><pub-location><style face="normal" font="default" size="100%">530 WALNUT ST, PHILADELPHIA, PA 19106-3621 USA</style></pub-location><volume><style face="normal" font="default" size="100%">174</style></volume><pages><style face="normal" font="default" size="100%">339-345</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We studied the dynamics of texture, bulk density, exchangeable bases, acidity, and aluminum in the uppermost Surface 50 con of Mediterranean Ultisols under natural vegetation at variable degradation stages and tinder different soil uses in the Canamero's rana formation (southwest Spain).

The total organic matter content decreased, starting from the virgin soil, under cork oaks, to the most heavily degraded soil (that under olive trees), whereas the bulk density increased. The total contents of exchangeable Ca, Mg, Na, and K significantly decreased in the same trend as organic matter. In contrast, the amount of aluminum extracted by 1N KCl, Al(K), remained essentially constant or even increased with increasing soil degradation.
