The loss of weight of the decomposing oak leaves was 623, j, after 24 months. In general, it is physical factors (mainly precipitation) which limit the decompo- sition of the evergreen oak leaves. Different patterns of bioelement losses were observed, increasing the relative content of N and P, and decreasing the amounts of Mg, K and Na in the decomposing leaves.</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%">Hernandez, I M</style></author><author><style face="normal" font="default" size="100%">Gallardo, J F</style></author><author><style face="normal" font="default" size="100%">SANTA-REGINA, I</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">DYNAMIC OF ORGANIC-MATTER IN FORESTS SUBJECT TO A MEDITERRANEAN SEMIARID CLIMATE IN THE DUERO BASIN (SPAIN) - LITTER PRODUCTION</style></title><secondary-title><style face="normal" font="default" size="100%">ACTA OECOLOGICA-INTERNATIONAL JOURNAL OF ECOLOGY</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">forest ecosystems</style></keyword><keyword><style  face="normal" font="default" size="100%">LITTER PRODUCTION</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><publisher><style face="normal" font="default" size="100%">GAUTHIER-VILLARS/EDITIONS ELSEVIER</style></publisher><pub-location><style face="normal" font="default" size="100%">23 RUE LINOIS, 75015 PARIS, FRANCE</style></pub-location><volume><style face="normal" font="default" size="100%">13</style></volume><pages><style face="normal" font="default" size="100%">55-65</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The production of litter was determined in three forest ecosystems in&lt;br/&gt;the Duero basin (Spain): a climax oak forest of Quercus rotundifolia and&lt;br/&gt;two repopulated pine forests of Pinus pinea and P. pinaster.&lt;br/&gt;The time-course of the litter fall both from the different organs of the&lt;br/&gt;trees and as a total was followed.
