为什么蚁狮幼虫在落叶层下很少见?检验诱捕器维护不当的假设 为什么蚁狮幼虫在落叶层下如此罕见?检验诱捕器维护不当的假设
了解动物避开某些生境的原因是完善生境选择理论的必要条件。这对于半定居的生物(如蚁蚁幼虫)至关重要,因为一旦定居下来,它们就很少移动,它们的表现在很大程度上取决于当地的环境条件。蚁狮幼虫是坐等的捕食者,它们在沙质土壤中建造圆锥形陷阱来捕捉路过的猎物。它们不断地清理陷阱,把泥土、猎物尸体和残骸从坑里赶出去,以保持陷阱的成功。因此,我们建议它们避免有凋落叶的土壤,因为叶子阻碍了它们的坑的维护;一个尚未被验证的假设。在墨西哥的热带半落叶森林中,我们首先证明了蚁幼虫在凋落叶土壤中是罕见的。然后,我们通过在90个蚁笼中添加碎屑来测试凋落叶对坑维护的影响,其中45个被叶子覆盖,45个未被覆盖。在加入碎片两小时后,我们记录了它的位置,并量化了坑的深度和直径的变化。无盖陷阱的幼虫清理垃圾的效率是有盖陷阱的两倍。此外,在仅仅2小时内,有盖圈闭比对照圈闭平均浅21%,这可能是因为清理碎屑的失败尝试导致沙流部分填充了坑。落叶层似乎阻碍了蚁狮陷阱的适当维护,至少部分解释了为什么这些动物在落叶层下很少见。

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.
