Predation rates were lower on farmland than in the forest habitat. There was a trend towards lower predation on the forest edge than in the interior. This edge-core predation gra- dient differed from the usual pattern of nest predation found in other temperate fragmented forests. Predation by rodents was almost completely restricted to the forest habitat. We suggest that in very small fragments, such as those studied here, a 'packing effect' of small specialist forest predators could be the cause of high predation rates throughout the forest.</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%">Tellería, J L</style></author><author><style face="normal" font="default" size="100%">Santos, T</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Spatiotemporal patterns of egg predation in forest islands: an experimental approach</style></title><secondary-title><style face="normal" font="default" size="100%">Biological Conservation</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Forest patches</style></keyword><keyword><style  face="normal" font="default" size="100%">forest size</style></keyword><keyword><style  face="normal" font="default" size="100%">fragmentation (voyant)</style></keyword><keyword><style  face="normal" font="default" size="100%">predation rates</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1992</style></year></dates><volume><style face="normal" font="default" size="100%">62</style></volume><pages><style face="normal" font="default" size="100%">29-33</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Thirty holm oak Quercus rotundifolia forests, ranging from 0·1 to 350 ha, were studied in central Spain to analyse the spatial and temporal patterns of predation in relation to size of forest patches. During two springs (1988 and 1989), quail Coturnix coturnix eggs were placed in these forests to evaluate predation rates. Two trials (April and June) during each year were performed to study the intraseasonal and interyear constancy of predation. Results showed that predation rate tends to increase with forest fragmentation, although forest size was poorly related to predation rate. Predation rates seemed to be constant within spring seasons and between years. These results suggest that predators concentrate their search activities in some selected forests, thus accentuating their effect on prey species.</style></abstract></record></records></xml>
