“…Experimental studies demonstrated that changes in plant communities along successional dynamics relate to the diversity of ground-arthropod communities [9,29], a relationship often reported in the context of bioindication [30][31][32]. Hence, we presume that changes in the vegetation structure (cover and spatial pattern) of dryland ecosystems could also be linked to changes in ground-arthropod communities, especially in the distribution of meso-and microarthropods.…”

The ecological functioning of dryland ecosystems is closely related to the spatial pattern of the vegetation, which is typically structured in patches. Ground arthropods mediate key soil functions and ecological processes, yet little is known about the influence of dryland vegetation pattern on their abundance and diversity. Here, we investigate how patch size and cover, and distance between patches relate to the abundance and diversity of meso-and microarthropods in semi-arid steppes. We found that species richness and abundance of ground arthropods exponentially increase with vegetation cover, patch size, and patch closeness. The communities under vegetation patches mainly respond to patch size, while the communities in the bare-soil interpatches are mostly controlled by the average distance between patches, independently of the concurrent changes in vegetation cover. Large patches seem to play a critical role as reserve and source of ground arthropod diversity. Our results suggest that decreasing vegetation cover and/or changes in vegetation pattern towards small and over-dispersed vegetation patches can fast lead to a significant loss of ground arthropods diversity in drylands.

“…Concerning ground arthropods, the input data are counts of ground arthropods sampled in soil and litter during winter and summer, totaling 40 samples per site (see Supplement 2 for details). Part of these data were previously analyzed to explain the colonization of ground arthropods during the development of the forest 57,60 . The organisms are sorted by species (occasionally morpho-species), and data of distinct samples are joined in only one large sample per site.…”

“…This explanation would imply that the successional process does not produce entropy in litter and soil layers or that ground arthropods are not sensitive to such a process. This hypothesis appears to be implausible due to strong experimental evidence attesting to the contrary 1,4,17,18,27,57,60,64 . The alternative explanation assumes that the cause-effect relationship exists, but W , A and H are unable to properly assess entropy production in soil communities.…”

Diversity indices provide simple and powerful metrics for assessing biological communities. Based on entropy measures, the approach considers statistical and thermodynamic inferences to deduce ecological patterns. However, concerns exist regarding the accuracy of diversity indices. Because relative quantities depend on the sorting of organisms (e.g., guilds and species) and their interactions, field observations carry inherent imprecision, thus leading to misinterpretation. Here, we present a framework that is able to appropriately achieve the thermodynamic properties in ecological systems and ensure the inference power. We demonstrate that effective abundances rather than raw abundances provide a trustful estimator of probabilities, which is evaluated through massive tests. We use empirical and synthetic data to show the advantages and reliability of this new framework under a broad range of conditions. The tests demonstrate that the replication principle is always optimized by the new estimator. Compared to other methods, this approach is simpler and reduces the importance of schemes used for sorting organisms. We highlight the robustness and the valor of effective abundances for ecological contexts: i) to assess and monitor the biodiversity, ii) to define the best sorting of organisms according to maximum entropy principles, and iii) to link local to regional diversity (α-, β-, and γ-diversity).

“…Specifically, invertebrates can indicate the soil quality well (Crepaldi et al 2014). Soil and leaf litter arthropods, particularly ants, are involved in important ecological processes that provide them as potential bio-indicators (Meloni 2012). Because ants have a wide geographical distribution, have a high abundance locally, act in various trophic levels, are easy to identify, use various ecological niches and can be classified into functional groups with biotic factors, they are ideal as bio-indicators (Osborn et al 1999;Silva and Brandão 1999).…”

This study quantified the concentration of heavy metals (copper, zinc, cadmium, lead and nickel) in the biomass of two ant species, Camponotus atriceps and Dorymyrmex brunneus, which are dominant in forests and crop areas, respectively, in Sinop, Mato Grosso, Brazil. Ant sampling pitfall traps were used in both land use types, and metal concentrations in the biomass were obtained by means of atomic absorption spectrometry. The two species were selected because they were the most abundant in each land use type, considering the volume of biomass necessary for the chemical analysis. The results showed that with the exception of copper, heavy metals revealed higher concentrations in D. brunneus from crop areas than in C. atriceps from native forests. Such results are associated with the fact that the crop areas received high inputs of agrochemicals through the management of corn and soybean crops. Thus, ants are good indicators of contamination and environmental pollution in tropical regions, as the highest concentration of heavy metals was expected in the crop areas in relation to the adjacent forest area.
