We approached the enchytraeid assemblages of urban holm oak stands in Naples and Siena adopting a high intensity sampling that, for the first time in the Mediterranean climate zone, would ensure that the data collected be representative of the target populations. Structural parameters (di- versity and evenness, biomass, size classes, aggregation) were compared across different spatial (regional, urban district, within habitat) and temporal scales (season and year). Species richness was found to change significantly only at regional scale; background data suggest that this may depend on the higher environmental heterogeneity occurring at Naples. Differences in size class structure were significant only on a seasonal scale and within either city separately. With one exception (Fridericia bulbosa s.s.), the patterns of spatial aggregation of the common species were fairly robust and the total range of patchiness was consistent with previous studies, despite the different sampling methodologies. The size of the sampling unit, the number of replicates per plot and the number of plots proposed in this study appear suitable to obviate the difficulties of evaluating Mediterranean enchytraeid communities.</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%">Rota, Emilia</style></author><author><style face="normal" font="default" size="100%">Caruso, Tancredi</style></author><author><style face="normal" font="default" size="100%">Monaci, Fabrizio</style></author><author><style face="normal" font="default" size="100%">Baldantoni, Daniela</style></author><author><style face="normal" font="default" size="100%">De Nicola, Flavia</style></author><author><style face="normal" font="default" size="100%">Iovieno, Paola</style></author><author><style face="normal" font="default" size="100%">Bargagli, Roberto</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of soil pollutants, biogeochemistry and microbiology on the distribution and composition of enchytraeid communities in urban and suburban holm oak stands</style></title><secondary-title><style face="normal" font="default" size="100%">Environmental Pollution</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Enchytraeids</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean urban communities</style></keyword><keyword><style  face="normal" font="default" size="100%">Microbiology</style></keyword><keyword><style  face="normal" font="default" size="100%">Pollutants</style></keyword><keyword><style  face="normal" font="default" size="100%">Soil biogeochemistry</style></keyword><keyword><style  face="normal" font="default" size="100%">terrestrial annelids</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2013///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0269749113002273</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">179</style></volume><pages><style face="normal" font="default" size="100%">268 - 276</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Holm oaks form typical urban woodlands in the Mediterranean region.
