1.生物的 扩散能力对于决定物种的景观种群结构以及它们在破碎的景观中生存的可能性是至关重要的。利用标记重捕获技术，研究了单食性线纹夜蛾的斑块内和斑块间的扩散能力、景观水平的种群结构以及甲虫密度和寄主斑块特征在设定扩散距离、数量和时间上的作用。
Abstract. 1. Dispersal capabilities of organisms are critical in determining the landscape population structure of species as well as their likelihood of survival in fragmented landscapes. Using mark–recapture techniques on the monophagous weevil Rhyssomatus lineaticollis Say (Curculionidae), within‐ and between‐patch dispersal capabilities, landscape level population structure, and the role of beetle density and host patch characteristics in setting distances, amounts, and timing of dispersal were studied.
