As a result of planting foreign tree species, the leaf litter composition and thus the food resources of native saprophagous macroarthropods will change, possibly altering primary decomposition processes. Therefore, experiments concerning the acceptance and palatability of introduced versus native litter for native isopods were undertaken. Consumption rates of four native isopod species (Porcellio scaber, Oniscus asellus, Trachelipus rathkii, Trachelipus ratzeburgii) were investigated in laboratory choice tests with introduced (Quercus pubescens, Quercus frainetto, Quercus ilex) and comparable native (Fagus sylvatica, Quercus robur) leaf litter. Litter was characterized by measurement of C/N-ratios and lignin content. Although species-specific preferences of isopods could be observed in the experiments, Mediterranean oak litter was consumed by all investigated species. Furthermore, two isopod species even preferred the leaf litter of the introduced Q. ilex. Compared to native beech or oak litter, litter from these introduced tree species thus apparently do not negatively influence the consumption rates of terrestrial isopods. Possible reasons for the determined preferences are discussed.</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%">Ferns, Peter N.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Feeding behaviour of autumn passage migrants in north east Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">Ringing &amp; Migration</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Feeding activity</style></keyword><keyword><style  face="normal" font="default" size="100%">Feeding habits (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">migration</style></keyword><keyword><style  face="normal" font="default" size="100%">passerines</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1975</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1975///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1080/03078698.1975.9673692</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">1</style></volume><pages><style face="normal" font="default" size="100%">3 - 11</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">IN THE SUMMER and autumn of 1973, a mist netting site in the sparsely wooded hill country of north east Portugal was continuously manned by members of the Iberian Ringing Group. The main objective was to study the increases in weight of trans-Saharan passerine migrants which use this particular area as a staging post on their southward journey (Mead 1968). These migrants arrive on the central Iberian plateau towards the end of a long, dry summer, at a time when conditions appear relatively inhospitable. Yet Willow Warblers* and Pied Flycatchers gain over 0.2 g/day in weight, while Whitethroats increase by over 0.4 g/day (C. J. Mead and B. R. Watmough in prep.). Though this is somewhat less than, for example, the 0.6 g/day gained by Whitethroats at Lake Chad, Nigeria, in preparation for the return journey to the Palaearctic in spring (Fry. Ash and FergusonLees 1970), it still suggests that reasonable food supplies are available. In order to determine the nature of the foods being taken by these migrants, a series of observations were made during late August and early September 1973 in association with mist-netting activities.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">doi: 10.1080/03078698.1975.9673692doi: 10.1080/03078698.1975.9673692The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Taylor &amp; Francis</style></notes></record></records></xml>
