DNA Metabarcoding reveals spatial and temporal variation of fish eye fluke communities in lake ecosystems

This Data set includes the eye fluke diversity (Diplostomidae) revealed by dna metabarcoding in two fish species (Eurasian perch and common roach) collected at seven lakes in Estonia ( North-East of Europe). Our data revealed a high degree of heterogeneity with significant differences in parasite communities between host, lakes and sites within lakes., as well a temporal variation. Also, revealed novel associations between parasites species that could also affect the variability of diplostomids communities. .These results indicate that diplostomid communities in temperate lakes are complex and dynamic systems exhibiting both spatial and temporal heterogeneity. They are influenced by various environmental factors and by host-parasite and inter-parasite interactions.

本数据集收录了源自爱沙尼亚（欧洲东北部）七个湖泊中采集的两种鱼类（欧亚鲈和普通鲢）的DNA条形码分析揭示的吸虫目（Diplostomidae）多样性。研究发现，宿主、湖泊及其内部不同区域的寄生虫群落存在显著的异质性，并伴随时间变化。此外，还揭示了寄生虫物种之间新的关联，这些关联可能影响吸虫目群落的变异性。研究结果表明，温带湖泊中的吸虫目群落是复杂且动态的系统，表现出空间和时间上的异质性，并受到多种环境因素以及宿主-寄生虫和寄生虫间的相互作用的影响。
