农业景观对一种定居蝴蝶扩散相关特征的景观影响
农业集约化造成了自然栖息地的丧失和破碎化,对农田生物多样性产生了负面影响。与此同时,重要资源的隔离可能有利于提高飞行昆虫的扩散能力,从而导致不同景观中飞行形态和扩散倾向的差异。我们在四组重复的地貌景观中采集了蝶形花蜉蝣(Coenonympha pamphilus),每组景观由(a)高度破碎化和集约化的 "现代 "地貌景观和(b)破碎化程度较低的 "传统 "农业地貌景观组成。我们比较了两种景观类型中采集到的蝴蝶的状况(即储量)、飞行形态、扩散能力和倾向。我们还测试了不同空间尺度的景观组成和配置对蝴蝶特征的影响。结果发现,不同景观类型之间没有差异,但各种景观特征都会影响蝴蝶的性状,这表明景观异质性与蝴蝶扩散之间存在复杂的相互作用。特别是,农作物田比例较高的景观似乎被选择为提高扩散能力的表型。由于扩散是破碎景观中元种群持续存在的一个关键因素,我们认为,在讨论农业景观中昆虫数量下降的问题时,应考虑与组成和构型景观异质性有关的扩散限制因素。

期刊介绍: Ecological Entomology publishes top-quality original research on the ecology of insects and related invertebrate taxa. Our aim is to publish papers that will be of considerable interest to the wide community of ecologists who are motivated by ecological or evolutionary theory. The suitability of a manuscript will usually be assessed within 5 days. We publish full-length Original Articles as well as Reviews, Short Communications, Methods and Natural History papers. In Original Articles, we greatly prefer papers that test specific hypotheses and which have a high degree of novelty. All categories aim for innovative contributions that advance the subject of ecological entomology.
