摘      要：Understanding the factors determining the formation of each community and metacommunity across a landscape is one of the most important ideas in soil animal ***,the variables and parameters that shape soil arthropod communities in agroecosystems have not been *** arthropods can serve as important bioindicators of field management and its *** sampled five com plantations in each of three locations across a region spanning 600 km to come up with these determinants of the community structure of ground-dwelling spiders(Erigoninae:Araneae),carabids(Coleoptara:Carabidae),and ants(Hymenoptera:Formicidae).The analysis of the five fields within each of the three locations represent our local-scale samples,while the comparisons of the 15 sites across all three locations represent the regional scale *** tested the hypothesis that in the models we sampled,environmental/soil variables would drivecommunity assembly locally(within location comparisons),but at the regional scale(between location comparisons),climatic and spatial variables would drive metacommunity *** outcomes of our study showed distinct communities at each of the three locations when compared across regions but locally,fields were similar in species composition,as ***,spatial variables were important but not soil variables,regulated species richness and *** contributed more than nestedness to explain the biodiversity of spiders,carabids,and ants at both the local and regional *** purely climate variables,nor purely soil or spatial variables were significant enough explanations for the regional scale arthropod community ***,spatially structured environmental factors contributed most to explain the patterns supporting our *** conclude that biodiversity in this agroecosystem area can be promoted by a mosaic of land uses being encouraged to increase landscape complexity at the regional scale.
