摘要

摘要:亚马逊河流域的河豚与植被的关系主要是在溪流中研究的。在这项研究中，我研究了秘鲁亚马逊地区一个牛轭湖周围两种植被类型(灌木和草本)中成虫的丰度。沿着每个栖息地的样带，在时间块上进行了蛙类的日间视觉采样。共鉴定出13个分类群。5种植物在两种生境中相似丰富，其中3种主要以草本植物为主，1种主要以灌木为主，且在时间块间无差异。结果表明，大部分异翅目和夜翅目昆虫适应于湖泊的无荫区。在少雨无阳的日子里也观察到一些蛇蜥，这表明它们适应热带气候的多雨条件。

Abundance of Odonata in different microhabitats at an oxbow lake in the Peruvian Amazon

ABSTRACT The relationship between Odonata and vegetation in Amazonia has been studied primarily in streams. In this study, I examined the abundance of adult Odonata in two vegetation types (shrubs and herbs) surrounding an oxbow lake in the Peruvian Amazon. Daytime visual samplings of Odonata were carried out in time blocks along transects in each habitat. Thirteen taxa were identified. Five species were similarly abundant in both habitats, three used mainly herbs, and one mainly shrubs, with no variation among time blocks. The results suggest that most Anisoptera and Zygoptera are adapted to unshaded areas of the lake. Some Odonata also were observed during sunless days with light rainfall, suggesting they are adapted to rainy conditions in tropical climate.
