This allows to understand the effect of atmospheric PAH contamination on soil PAH content via litterfall. At this aim, we studied mass and PAH dynamics of Quercus ilex leaf litters collected from urban, industrial and remote sites, incubated in mesocosms under controlled conditions for 361d. The results highlighted a litter decomposition rate of leaves sampled in urban&gt;industrial&gt;remote sites; the faster decomposition of litter of the urban site is also related to the low C/N ratio of the leaves. The PAHs showed concentrations at the beginning of the incubation of 887, 650 and 143ngg−1d.w., respectively in leaf litters from urban, industrial and remote sites. The PAHs in litter decreased along the time, with the same trend observed for mass litter, showing the highest decrease at 361d for the urban leaf litter. Anyway, PAH dynamics in all the litters exhibited two phases of loss, separated by a PAH increase observed at 246d and mainly linked to benzo[e]pyrene.</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%">Lunghini, D</style></author><author><style face="normal" font="default" size="100%">Granito, V M</style></author><author><style face="normal" font="default" size="100%">Di Lonardo, D P</style></author><author><style face="normal" font="default" size="100%">Maggi, O</style></author><author><style face="normal" font="default" size="100%">Persiani, A M</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fungal diversity of saprotrophic litter fungi in a Mediterranean maquis environment</style></title><secondary-title><style face="normal" font="default" size="100%">MYCOLOGIA</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">decomposition</style></keyword><keyword><style  face="normal" font="default" size="100%">fungal biodiversity</style></keyword><keyword><style  face="normal" font="default" size="100%">leaf-litter quality</style></keyword><keyword><style  face="normal" font="default" size="100%">Litter bags</style></keyword><keyword><style  face="normal" font="default" size="100%">Mediterranean maquis</style></keyword><keyword><style  face="normal" font="default" size="100%">monospecific/mixed litter</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><publisher><style face="normal" font="default" size="100%">ALLEN PRESS INC</style></publisher><pub-location><style face="normal" font="default" size="100%">810 E 10TH ST, LAWRENCE, KS 66044 USA</style></pub-location><volume><style face="normal" font="default" size="100%">105</style></volume><pages><style face="normal" font="default" size="100%">1499-1515</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Monospecific and mixed-leaf litters from plant species of Mediterranean maquis (Quercus ilex, Phillyrea angustifolia, Pistacia lentiscus, Cistus spp.) in an undisturbed area in southern Italy were studied with respect to the structure and composition of their decomposer fungal community over an incubation period of 403 d. The data matrix structure was analyzed by means of detrended correspondence analysis (DCA), while indicator species analysis (ISA) was used to determine the preferential association of species with a substrate, a succession phase and monospecific/mixed experimental conditions. The ecological nature of the gradient expressed by the DCA axes was investigated by means of experimental and main chemical leaf-litter variables. The litter mixture had non-additive effects on the decomposition process even though the fungal species richness of the mixed litter was considerably higher than that of the monospecific litter. Our findings highlight the occurrence of shifts in the fungal community during decomposition in response to changes in the substrate, such as those related to the cellulose content and lignin/N ratio.</style></abstract></record></records></xml>
