Evernia prunastri (L.) Ach. hyphae progress into xylem vessels of Fagus sylvatica, Quercus pyrenaica and Betula alba. This is on the basis of a mechanism through which Lichens inject metabolic inhibitors in the xylem vessels, and, after their translocation in the xylem sap, they reach different organs of the phytophore and produce defoliation. In this report, we have noted that usnic acid is more impermeant than atranorin through the chloroplast membrane of Quercus rotundifolia leaves. On the other hand, we have also noted the degradation of chlorophyll in response to Lichen substances.</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%">Serra, A</style></author><author><style face="normal" font="default" size="100%">Miquel, C</style></author><author><style face="normal" font="default" size="100%">Mateos, E</style></author><author><style face="normal" font="default" size="100%">Vicente, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Study of a soil Julidae community in Mediterranean forest (Diplopoda, Julida)</style></title><secondary-title><style face="normal" font="default" size="100%">ENTOMOLOGICA SCANDINAVICA</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">commun</style></keyword><keyword><style  face="normal" font="default" size="100%">diplopoda</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest</style></keyword><keyword><style  face="normal" font="default" size="100%">millipede</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><publisher><style face="normal" font="default" size="100%">ENTOMOL SCANDINAVICA</style></publisher><pub-location><style face="normal" font="default" size="100%">DEPT OF SYST ZOOL HELGOVAVAGEN 3, S-223 62 LUND, SWEDEN</style></pub-location><pages><style face="normal" font="default" size="100%">291-299</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This work is part of a larger study on the communities of epigean and&lt;br/&gt;edaphic arthropods from the Pare Natural de Sant Llorenc de Munt&lt;br/&gt;(Barcelona, Spain). The study was performed in an experimental plot in a&lt;br/&gt;sclerophyllous forest of Mediterranean climate, consisting mainly of&lt;br/&gt;Quercus ilex and Pinus halepensis. Field sampling was performed during&lt;br/&gt;25 consecutive months in order to quantify the density of Julidae. In&lt;br/&gt;the experimental plot (40 x 40 m), three horizons were sampled: L+F&lt;br/&gt;(leaf litter fall), H (humus), and A (the first five cm oft he mineral&lt;br/&gt;layer). Among the studied material, we found four species of Julidae:&lt;br/&gt;Cylindroiulus punctatus (Leach, 1815), Cylindroiulus sanctimichaelis&lt;br/&gt;Attems, 1927, Leptoiulus belgicus (Latzel, 1884), and Ommatoiulus&lt;br/&gt;sabulosus (Linnaeus, 1758), with mean densities of 39.45, 35.22, 3.79&lt;br/&gt;and 0.77 ind./m(2), respectively. We didn't find significant differences&lt;br/&gt;in mean density between months during the study period for any of these&lt;br/&gt;four species. The vertical distribution along the edaphic profile was&lt;br/&gt;evaluated using the index of Usher. All species showed a preference for&lt;br/&gt;horizon H, with occasional migrations towards the deeper level A, or the&lt;br/&gt;shallower level L/F. The analysis of the distribution of juvenile and&lt;br/&gt;adult specimens indicated that the reproductive periods occurred mostly&lt;br/&gt;in late winter or spring, while the recruitment occurred in spring-early&lt;br/&gt;summer.</style></abstract></record></records></xml>
