“…In our study, terrain at each local site is very flat with no more than 0.5 m altitude difference (measured data), this means there were no considerable geographical barriers for arthropods dispersal at the local scale. Considering the dispersal abilities of carabids and ants (Schuldt and Assmann, 2011), we showed that the high dispersal abilities of carabids and ants allowed movement from one plot to the other, so that a significant spatial signal was detected for both carabids and ants (Gao et al, 2018). At the regional scale, neither environmental factors (climate and soil variables) nor spatial factors significantly contributed to each arthropod composition and distribution.…”

Understanding the factors determining the formation of each community and metacommunity across a landscape is one of the most important ideas in soil animal ecology. However, the variables and parameters that shape soil arthropod communities in agroecosystems have not been resolved. These arthropods can serve as important bioindicators of field management and its sustainability. We sampled five corn 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 (Coleoptera: 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 samples. We tested the hypothesis that in the models we sampled, environmental/soil variables would drive

“…Although the literature reviewing the impact of fertilizers on natural predators is limited [86], carabid activity density has been positively linked to soil organic carbon content [87,88], as well as potassium and phosphate content [89][90][91], in both agricultural and forested systems. Increasing levels of organic carbon, often through addition of SOM and therefore leading to higher CN ratios, may be associated with increasing amounts in soil microorganisms and mesofauna, indirectly promoting the carabid food chain.…”

Sustainable vineyard management in inter-rows may improve biodiversity and ecosystem service provision in landscapes with a high density of vineyards. The current work investigates the effect of three inter-row ground cover treatments (bare soil by tillage, alternating and complete vegetation cover) on carabid beetle communities and vine vitality, in relation to climatic, soil and landscape parameters. Pitfall traps were used to collect carabids in the spring and autumn of 2016 from nine Austrian vineyards, with all three ground cover treatments established in each vineyard. Additionally, grape berry samples were collected before harvest in order to determine juice quality parameters. Generalized linear mixed models revealed that complete vegetation cover, the most extensive vineyard inter-row management, decreased both carabid density and species richness. The variables hours of sunshine, vineyard cover at the landscape scale and mesofauna abundance had negative impacts on species richness. The largest differentiator of carabid communities was the sampling timepoint, and we observed clustering associated to vineyard manager, whereas ground cover treatment played no significant role. The importance of treatment on vine vitality parameters was low; however, complete vegetation cover was detrimental to vine vegetative growth and berry weight. On the basis of our results, we conclude that although community composition may be influenced by pedo-climatic conditions and landscape components, alternating vegetation cover is an option for maintaining both carabid diversity and high-quality berries in vineyards.

“…At a small scale that was less than 10 3 m (Hortal et al, 2010), the dispersal limitation should not be important for grounddwelling beetle communities because of the fewer geographical barriers. Unfortunately, little attention has been paid to small-scale communities despite the importance of determining the mechanisms for ground-dwelling beetles at various spatial scales (but see (Gao et al, 2018a)).…”

Disentangling the relative roles of environmental and spatial processes in community assembly is a major task of community ecology. It is necessary to uncover this question at multiple spatial scales; however, the relative importance of spatial and environmental processes on ground-dwelling beetle assembly at a small scale is still unclear. Based on two permanent plots (each 300 m) located in primary mixed broadleaved-Korean pine forests, the topographic, soil, and plant factors were collected, and the spatial variables (MEMs, distancebased Moran's eigenvector maps) were calculated. A redundancy analysis (RDA) was used to evaluate the influence of topographic, soil, and plant variables on ground-dwelling beetle compositions. A variation partitioning analysis was used to quantify the relative contributions of environmental and spatial processes on the assembly of ground-dwelling beetles. The results of the RDA reported that the soil, plant, and topographic variables affected Staphylinidae and Silphidae beetle compositions in both plots. According to the results of variation partitioning, pure soil and plant variables were important for the assembly of Silphidae beetles in the LS plot. The contributions of pure topographic, soil, and plant variables were significantly lower than those of pure spatial variables. The contributions of pure spatial variables were significant for the assembly of Staphylinidae and Silphidae beetles in both plots. In addition, the relative importance of environmental and spatial processes was not significantly changed after including more environmental variables and the unexplained variations. Finally, this study suggests that both spatial and environmental variables are important for the assembly of ground-dwelling beetle communities, while pure spatial variables are more important than pure environmental variables at a small scale (300 m).
