Abstract We developed an index of vulnerability for odonates (IVO) that occurred predominantly in Mexico to assess land use change. Vulnerability was defined as a function of A) habits of the species and B) ecological niche models. Index validation was done by relating it to rate of vegetation cover change, with the habitat preferences of each species and with species’ sensitivity to habitat deterioration. Thus, the most sensitive species would be found in areas with no change in land use. IVO values ranged from a maximum of three (i.e., the most sensitive) to a minimum of one (i.e., the least sensitive). As it was demonstrated in other studies, odonates did not show a clear preference between conserved and perturbed land uses. Interestingly, the few sensitive species were clearly resilient and can be found in a wide range of land use types, thus they may be more generalist than previously thought.

使用生态位模型估计豆娘和蜻蜓（昆虫纲：蜻蜓目）对土地利用变化的脆弱性的指数

摘要 我们开发了一个主要发生在墨西哥的 odonates (IVO) 脆弱性指数，以评估土地利用变化。脆弱性被定义为 A) 物种习性和 B) 生态位模型的函数。指数验证是通过将其与植被覆盖变化率、每个物种的栖息地偏好以及物种对栖息地恶化的敏感性相关联来完成的。因此，最敏感的物种将出现在土地利用没有变化的地区。IVO 值的范围从最多三个（即最敏感）到最少一个（即最不敏感）。正如在其他研究中所证明的那样，齿状体在保护和扰动的土地利用之间没有表现出明显的偏好。有趣的是，少数敏感物种显然具有复原力，可以在广泛的土地利用类型中找到，
