Measurements were made on six occasions throughout the year to take into account seasonal variations in (i) the quality of decomposing leaves, (ii) the physiological state of the animals, and (iii) temperature plus photoperiod. The mean weight-specific consumption rate was 14 g (dry weight) g-1 (live weight) y-1 , which is much higher than published figures for Mediterranean oak leaf litter. The consumption rate was highest in spring (51 mg g-1 d-1 ) and lowest in summer (28 mg g-1 d-1 ), the summer consumption rate being even lower when determined with air-dried leaves (17 mg g-1 d-1 ). Assimilation efficiency averaged 6 % for the year, with a maximum in spring (9 %) and a minimum in winter (1 %). A much higher assimilation efficiency (29 %) was measured with freshly fallen leaves, but a food preference experiment showed that these leaves were generally avoided and that G. marginata preferred more decomposed leaves despite their lower digestibility.

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><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%">Bertrand, M.</style></author><author><style face="normal" font="default" size="100%">Lumaret, J.
