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%">Cartan-Son, M.</style></author><author><style face="normal" font="default" size="100%">Floret, C.</style></author><author><style face="normal" font="default" size="100%">Galan, M.

Several hypo- theses have been put forward to provide an explanation for this phenomenon: (i) senescence of coppice stumps; (ii)limited availability of water and nutrient resources; (iii)intershoot and inter-plant compe- tition. To test some of these hypotheses, growth response to rainfall distribution and nutrient supply (NPK), and the influence of edge effects after clear-cutting were studied in a 40-yr old stand. Curves of radial increment were compared with precipitation and umbrothermic patterns for the 6 years studied. Water availability apparently accounted for some inter-annual differences in growth. However, it was not mean annual rainfall, but rather rainfall occurring in late spring-summer (June, July) which played a large role in determining radial growth. Radial growth was also increased by nutrient supply. Its positive effect was strengthened by favourable rainfall in 1987. Edge-effects following a clear-cut were also found, both in the first year and in four succeeding years following the cut. This comprised in greater radial growth rate for all shoots, with reduced repression of smaller shoots by the larger ones. The effect decreased over a distance of 10 m with increasing distance from the cut field. This could be explained by increased availabiDLy of water, nutrient resources, and light.</style></abstract><issue><style face="normal" font="default" size="100%">i</style></issue></record></records></xml>
