东地中海飞行路线沿线甲虫迁徙的高死亡率

就增加的能量消耗和途中遇到的风险而言，移徙代价高昂。与久坐不动的生活史阶段相比，这些因素可能导致移民的死亡率更高。昆虫的迁徙数量多得令人难以置信，但由于它们不像脊椎动物那样引人注目，而且迁徙通常发生在高海拔和广阔的前沿，因此很难研究与迁徙相关的死亡率。与迁徙有关的死亡率的一个主要信息来源是在海上穿越失败后在搁浅线上发现的尸体。在这里，我们分析了数千万昆虫沿着东地中海飞行路线从中东大陆到塞浦路斯岛穿越开阔海洋100公里后的搁浅死亡率。所有的线记录都是关于两种甲虫，七斑瓢虫七星瓢虫和斑瓢虫Calosoma olivieri，而只有9只七星瓢虫被成功捕获，与其他昆虫群落一起越过海洋到达这里。主要的搁浅与东风有关，这表明它们来自中东大陆，这些个体被记录为极度虚弱，无法飞行或死亡。我们的研究结果表明，与其他迁徙昆虫组合的成员相比，甲虫是较弱的迁徙者，海洋跨越太远，大多数昆虫无法飞行，导致高死亡率。讨论了这种高死亡率对海洋生态系统的影响。

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.
