Study on the Diversity and Vertical Distribution of True Bugs in Taihang Mountains,Shanxi Province
In order to clarify the species diversity and distribution characteristics of true bugs in Taihang Mountains,Shanxi Province,a survey of true bugs diversity was conducted from June to September in 2022 and 2023,and vertical distribution at five different altitudes was analyzed in this area.The results of biodiversity analysis showed that a total of 6 103 true bugs were collected from June to September in 2022 and 2023,belonging to 25 families,41 subfamilies,110 genera,a total of 189 species.The dominant groups under different altitude gradients were different.The dominant group in altitude Ⅱ(770-1 140 m),altitude Ⅲ(1 140-1 510 m),and altitude Ⅴ(1 880-2 250 m)was Miridae.The dominant group at altitude Ⅰ(400-770 m)was Pentatomidae,and the dominant group at altitude Ⅳ(1 510-1 880 m)was Plataspidae.The altitude had significant effects on the individual number,species number,Shannon-Wiener diversity index and Pielou evenness index,but had no significant effects on Margalef richness index and Simpson dominance index.The species composition of true bugs community at different altitudes was less similar,and the species similarity coefficient was ranging from 0.040 8 to 0.147 5,the true bug community at altitude Ⅱ and altitude Ⅲ was more similar.The environmental factor that had the greatest influence on the species number of true bugs in Taihang Mountains of Shanxi Province was the precipitation in the hottest quarter of the collection site(BIO18),and the correlation coefficient was 0.238(P<0.05).The environmental factor that had the greatest influence on the individual number of true bugs in Taihang Mountains of Shanxi Province was the annual precipitation(BIO12),and the correlation coefficient was 0.263(P<0.05).In summary,the ecological environment of Taihang Mountains in Shanxi Province is diverse,and the resources of true bugs species are abundant.In this area,the species richness of true bugs in low and high altitudes is relatively smaller,while the species in middle altitudes are abundant,and the vertical distribution pattern is single-peak pattern.
