寄主植物和景观可预测繁殖帝王斑蝶对路边栖息地的使用情况

路边的植被虽然会带来一些风险，但也能为帝王斑蝶提供繁殖栖息地。我们研究了景观和特定地点因素如何影响路边作为帝王斑蝶繁殖栖息地的质量。我们调查了明尼苏达州路边 250 多个地点的奶草、花卉资源以及帝王斑蝶卵和幼虫。我们发现，乳草的分布受到邻近土地利用和地理环境的影响，在邻近农作物和草地的路边以及该州南部和西部更有可能出现乳草。帝王斑的卵和幼虫的存在和密度主要受奶草密度的影响，每个地点出现帝王斑的可能性随着奶草密度的增加而增加。在奶草密度较低的地点，每株奶草上的帝王斑密度增加，这表明在奶草稀少的地方，帝王斑卵更密集地集中在较少的植株上，而在奶草常见的地方，帝王斑卵则更稀疏地分布在植株上。帝王斑每株奶草的密度随着研究地点远离核心草地、向南以及在较窄的路边而增加，这也表明在栖息地稀缺的地区，帝王斑的使用率可能较高。与未修剪的乳草相比，修剪过的乳草中帝王斑的卵和幼虫密度更高。我们的研究表明，无论邻近的土地利用类型如何，路边栖息地都能有效地为帝王斑提供繁殖地点，即使远离优质自然区域也是如此。我们的研究结果有助于保护工作者为帝王斑和其他传粉昆虫规划和管理路边栖息地。
