新疆卡拉麦里国家公园蝗虫群落多样性及对植物群落的响应OA

In order to understand the community structure and diversity characteristics of grasshoppers in Kalamaili National Park,Xinjiang,a systematic survey of grasshoppers in Kashan from May to September 2024 was carried out by net capture method.The results showed that:1)A total of 4 992 grasshoppers were collected,belonging to 6 families,20 genera and 37 species of Acridoidea.Among them,the genus Sphingonotus(Oedipodidae)was the most abundant in this area(accounting for 56％of the total).2)The abundance of grasshoppers was mainly affected by the diversity and evenness of plant communities.According to the dominance of grasshoppers,the dominant species(3 species)in Kashan were the common monitoring species of Seriphidium terraealbae desert and Anabasis salsa desert,which were affected by Chenopodiaceae and Compositae vegetation,respectively.Among the common species(14 species),Dociostaurus kraussi was the unique monitoring species of Seriphidium terraealbae desert(affected by Asteraceae),Sphingonotus savignyi was the unique monitoring species of Haloxylon persicum desert(affected by Chenopodiaceae),Leptopternis gracilis and Leptopternis iliensis were the unique monitoring species of Krascheninnikovia ceratoides desert(affected by Chenopodiaceae and Asteraceae respectively).3)The γ diversity and α diversity exhibit a temporal trend of first increasing and then decreasing(with the highest in July),with the peak values of Shannon-Wiener diversity and Margalef richness index mainly gathered in July.4)The difference of β diversity of grasshopper community was the largest between Haloxylon persicum desert and Anabasis salsa desert(βw=0.43,βc=10,Jaccard=0.39).The Seriphidium terraealbae desert was most similar to the Anabasis salsa desert desert(βw=0.12,βc=3.5,Jaccard=0.79).In summary,the diversity of grasshopper community in Kashan is relatively high,with July being the main occurrence period for locusts.The Seriphidium terraealbae desert is the grassland type with the highest diversity of grasshoppers,monitoring needs to be strengthened in habitats with Asteraceae and Chenopodiaceae as the main species.
