This paper explores the potential effects of host-plant fragmentation on cork oak gall wasp populations (Cynipidae, Hymenoptera) and on their predators, lethal inquilines, and parasitoids. To address this objective, galls were collected across a gradient of cork oak (Quercus suber) forest fragmentation in the East Pyrenees (Albera, Spain), and they were incubated to obtain the parasitism rates. 2. Two hypotheses were tested: (1) Host-plant fragmentation may induce a decline in gall wasp populations because of area and isolation effects on local extinction and dispersal; as a consequence of that, parasitoids may decline even more strongly in fragmented habitats than their prey. (2) Host-plant fragmentation may cause a decline in gall wasp parasitoid populations that, in turn, can lead to an ecological release in their prey populations. 3. Among the eight cork oak gall wasps sampled in the study area of Albera, the gall abundances of three species (Callirhytis glandium, Callirhytis rufescens, and Andricus hispanicus) were significantly related to forest fragmentation. The overall abundance of gall wasps was affected by a radius of ≈ 890 m surrounding landscape, presenting constant abundances with forest loss until forest cover is reduced at ≈ 40%; below that value the abundance increased rapidly. Three inquilines and 23 parasitoids species were recorded after gall incubation. In 25 cases, species of inquilines and parasitoids were newly recorded for the corresponding host in the Iberian peninsula. 4. Although the overall parasitism rate was high (1.1), it was uncorrelated with fragmentation and with overall cynipid abundance. These results indicate that host-plant fragmentation was correlated with higher abundance of gall wasps, whereas the parasitism rate could not explain this hyper-abundance in small forest fragments.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Blackwell Publishing Ltd</style></notes></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%">CHUST, GUILLEM</style></author><author><style face="normal" font="default" size="100%">GARBIN, LUCAS</style></author><author><style face="normal" font="default" size="100%">PUJADE-VILLAR, JULI</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Gall wasps and their parasitoids in cork oak fragmented forests</style></title><secondary-title><style face="normal" font="default" size="100%">Ecological Entomology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">fragmentation</style></keyword><keyword><style  face="normal" font="default" size="100%">gall wasp</style></keyword><keyword><style  face="normal" font="default" size="100%">parasitism rate</style></keyword><keyword><style  face="normal" font="default" size="100%">parasitoid</style></keyword><keyword><style  face="normal" font="default" size="100%">Pyrenees</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">82-91</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Abstract 1.

The results are based upon the identification of more than 2,000 charcoal pieces from prehistoric settlements. Firs and pines (Pinus sylvestris) persist in the Pyrenean area as far as the Neolithic, contrary to the south of the Massif Central where a Mediterranean influence is recorded. Refuges of vegetation give the best explanation for Late Glacial phytogeography; evidence for these refuges has been found at Belvis. In the Mediterranean area we can describe three vegetation successions during Postglacial time. The early vegetation was dominated by pines and deciduous oaks (Preboreal, Boreal). Later deciduous oak forests with thermophilous plants were growing (Atlantic period). Finally, in the Subboreal and Subatlantic period evergreen oak forests (Quercus ilex) are extended. The late extension of Quercus ilex (Subatlantic or earlier) is of anthropic origin.</style></abstract></record></records></xml>
