Abstract

Amphibiotic insects, chironomids of the genera Glyptotendipes and Chironomus, which emerged from saline Lake Shira, differed in composition and content of fatty acids, including the essential eicosapentaenoic acid (20:5n-3, EPA), and upon flying out they were concentrated in different territories, the riparian zone and remote arid steppe zone, respectively. Potential consumers of chironomids adults, the orb-weaver spiders Larinoides suspicax, which inhabited both zones, also differed in fatty acid composition. The main difference in their biochemical composition was a significantly higher level of EPA in spiders from the riparian zone that likely to be explained by consumption of the Glyptotendipes adults enriched in this fatty acid and concentrated only within this zone. The higher level of EPA, which is deficient in terrestrial ecosystems, in orb-weaver spiders from the riparian zone of the saline lake may potentially promote a successful survival of the consumers in the arid landscape.

居住在河岸带和草原的天体-韦弗蜘蛛之间的脂肪酸组成差异与不同的手足类分类单元的消费有关。

摘要

两栖昆虫，从盐湖盐湖中出现的Glyptotendipes和Chironomus属的虫类，其脂肪酸的组成和含量都不同，包括必需的二十碳五烯酸（20：5n-3，EPA），在飞出时，它们被集中在不同地区，分别是河岸带和偏远干旱草原带。居住在两个区域的天体成虫的潜在消费者，即球形 织布蜘蛛Larinoides suspicax，其脂肪酸组成也有所不同。它们的生化组成的主要差异是来自河岸带的蜘蛛中的EPA含量显着较高，这可能是由于食用了糖原虫成年人富含这种脂肪酸，并且仅在该区域内浓缩。来自盐湖河岸带的球形织布蜘蛛中较高水平的EPA（其陆地生态系统不足）可能潜在地促进消费者在干旱地区的成功生存。
