Effects of Caragana korshinskii shrub arrangements on the community structure of ground-active arthropods in desertified steppe
摘要
Abstract
Artificial shrub planting helps prevent wind erosion and sand encroachment,beneficial for ecological restoration efforts.However,varying shrub planting patterns exert distinct impacts on ground-active arthropod populations.Two planting arrangements of the Caragana koraiensis shrub-belt and point-were selected to reveal the impacts of ground-active arthropods on community composition,diversity,and functional group structure by the trap trapping method.The results showed that:(1)the richness of the dominant group in May and July was significantly reduced in the belt than in the point(P＜0.05),while the individual number and group richness of the common group in May and October was significantly higher in the belt than in the point(P＜0.05),the individual number and group richness of the rare group in July and October was significantly higher in the belt than in the point(P＜0.05).(2)In October the individual number of ground-active arthropods was significantly higher in the belt than in the point,the group richness in May,July and October was significantly higher in the belt than in the point(P＜0.05),the Shannon-Wienner diversity index in May and October was significantly higher in the belt than in the point(P＜0.01),while the Simpson dominance index in May was significantly lower in the belt than in the point(P＜0.01).(3)The Individual number of predatory in May and July was significantly lower in the belt than in the point(P＜0.05)the Individual number of phytophagous in May and July was significantly higher in the belt than in the point(P＜0.05).In October,the individual number of omnivorous was significantly higher in the belt than in the point(P＜0.05),the Individual number of other feeding habits(saprozoic,parasitic,and fungivorous)in May were significantly higher in the belt than in the point(P＜0.05).The group richness of predatory in May was significantly lower in the belt than in the point(P＜0.01),the group richness of phytophagous in May,July and October was significantly higher in the belt than in the point(P＜0.001),the group richness of omnivorous in May and October was significantly higher in the belt than in the point(P＜0.01),in July was significantly lower than that in point(P＜0.01),the group richness of other feeding habits(saprozoic,parasitic,and fungivorous)in May were significantly higher in the belt than in the point(P＜0.05).(4)Soil bulk density,soil pH,and herbaceous plant richness are the primary environmental factors influencing the distributional disparities in ground-active arthropod community structures across various shrub forest arrangements.In conclusion,comprehensive analysis shows that the belt arranged shrubs are more suitable for the survival and settlement of ground-active arthropods to maintain the relative stability of the food web structure and system of ground-active arthropods.关键词
