Abstract This study assessed black rat predation on artificial nests in relation to restoration undertaken in the Macaronesian laurel forest in Sao Miguel Island, Azores, evaluating three different points: nest predation rate; rodent relative abundance; and abundance of invertebrates, flowers and fruits. In general, artificial nest predation increased after habitat restoration, and significant differences were found on a successfully restored forest site between year 0 and year 10. Rodent capture rates were significantly higher one decade after habitat restoration, and there were significantly more flowers and fruits available in the area with a higher restoration success than in the area with less restoration success. The results show that habitat restoration leads to an increase of black rat relative abundance, which is consistent with the increasing of artificial nest predation, and with the higher abundance of vegetal food on the successfully restored forest site. It is important to study and analyze these complex interactions which can have an influence on the survival of target species to conserve.

栖息地恢复的不利因素：马卡罗尼西亚月桂树森林中入侵啮齿动物对人工巢穴的捕食

摘要 本研究评估了在亚速尔群岛圣米格尔岛马卡罗尼西亚月桂林中修复人工巢穴的黑鼠捕食情况，评估了三个不同的点：巢穴捕食率；啮齿动物相对丰度；以及丰富的无脊椎动物、花卉和水果。总体而言，栖息地恢复后人工巢穴捕食增加，成功恢复的林地在第 0 年和第 10 年之间存在显着差异。 栖息地恢复后 10 年啮齿动物捕获率显着提高，可利用的花卉和果实明显增多恢复成功率高的区域比恢复成功率低的区域。结果表明，栖息地恢复导致黑鼠相对丰度增加，这与人工巢穴捕食的增加以及成功恢复的林地植物食物的丰度一致。研究和分析这些复杂的相互作用很重要，这些相互作用可能对要保护的目标物种的生存产生影响。
