摘要

全球蝴蝶的数量正在下降，荟萃分析显示每年下降−2%。农业通过栖息地的丧失和退化导致蝴蝶数量减少。草原地带——积极恢复原生多年生植被的农田地带——是一种有可能减轻生物多样性损失的保护措施，但它们对蝴蝶生物多样性的影响尚不清楚。在一项30年前的实验中，我们将草原地带引入了管理不那么严格的作物处理，该实验改变了从自然区到农田（玉米-大豆-小麦轮作）的土地利用强度。处理方法包括保护性土地、带草原地带的生物（有机）行作物、带草原带的减少投入行作物、免耕行作物和传统行作物。我们测量了蝴蝶的丰度和丰富度：（1）在草原地带内，（2）在地块水平上跨越土地利用强度的梯度。草原地带的蝴蝶数量高于所有其他处理。在地块层面的土地利用强度梯度上，保护性土地处理的丰度最高，草原带处理的丰度中等，免耕和常规处理的丰度最低。同样，在整个地块上，蝴蝶的丰富度随着土地利用强度的降低而增加。草原地带的处理也降低了土地利用强度，具有独特的蝴蝶群落，因为它们含有其他行作物处理中没有的几种蝴蝶。除了已知的草原地带对生态系统服务的影响，包括侵蚀控制和水质改善，草原地带还可以增加多功能景观中的生物多样性。

期刊介绍： To publish papers of the highest scientific quality within the general area of insect (and other arthropods) conservation and diversity covering topics ranging from ecological theory to practical management. Papers are invited on the following topics: Conservation genetics; Extinction debt; Long-term conservation planning and implementation; Global implications of local or national conservation actions; Management responses of species and communities; Captive breeding programs; Comparisons of restored and natural habitats; Biogeography; Global biodiversity; Metapopulation dynamics; Climate change: impacts on distributions and range; Invasive species: impacts and control; Effects of pollution; Genetic threats to diversity by introgression; Effects of fragmentation on diversity and distribution; Impact of agricultural and forestry practices on biodiversity; Enhancing urban environments for diversity and protection; Biodiversity action plans: can we scale up from insects?; Effectiveness and choice of indicator species; Soil biodiversity and interactions with above-ground biodiversity; Ecological interactions at local levels; Ecological and evolutionary factors influencing diversity and local, regional and global scales; Sustainable livelihoods and training on the ground; Integrating science and policy.
