“…These results corroborate our previous study, in which we evaluated, through metagenomics, the patterns of microbial alpha and beta diversities in two out of six counties evaluated here (Goss-Souza et al 2017). Other authors also have found the same soil microbial patterns for both subtropical (Ceola et al 2021) and tropical soils (Rodrigues et al 2013;Mendes et al 2015b). When comparing seasons for the same land use, we found a loss in pairwise beta diversities from winter to summer in no-till and pasture, the same as found in our previous metagenomics study (Goss-Souza et al 2017).…”

“…This study has been conceived to advance our understanding of the possible shifts in soil microbial assembly patterns after long-term forest-to-agriculture conversion. Moreover, we have linked the biogeographical patterns of soil microbial communities to the consequences for ecological processes, niche occupancy, and ecosystem services, due to the deforestation of Brazilian tropical and subtropical forests (Mendes et al 2014(Mendes et al , 2015bGoss-Souza et al 2019, focusing on the Subtropical Atlantic Forest (Goss-Souza et al 2017; Ceola et al 2021).…”

“…distance-decays) between microbial communities. Moreover, just a few studies have quantified the coupled effects of spatial distance, abiotic and biotic factors on microbial diversity distribution, and ecological processes (Martiny et al 2011;Gao et al 2019;Zhao et al 2019;Ceola et al 2021). To our knowledge, this is the first study underlying those patterns and processes for bacterial communities across spatial scales, in Brazilian subtropical soils.…”

“…However, a few recent studies have raised the hypothesis that the distance decay relationship and, consequently, the ecological processes governing assembly in bacterial communities could vary between habitat generalists and specialists (Gao et al 2019;Luo et al 2019). While generalists follow the Baas Becking theory of "everything is everywhere" (De Wit and Bouvier 2006), habitat specialists are the microorganisms that have restricted occupancy, as represented by their low occurrence across environmental and geographical gradients (Meyer et al 2018;Gao et al 2019;Ceola et al 2021). The competitive/cooperative interactions among microbial populations in a local community (Li et al 2018) and sets of metapopulations in metacommunity (Hovatter et al 2011;Rocha et al 2021) are very intricate (Leibold et al 2004) and land-use change can greatly alter the role of these interactions in microbial community assembly (Creamer et al 2016;Brinkmann et al 2019;Goss-Souza et al 2020).…”

Understanding the effects of forest-to-agriculture conversion on microbial diversity has been a major goal in soil ecological studies. However, linking community assembly to the ruling ecological processes at local and regional scales remains challenging. Here, we evaluated bacterial community assembly patterns and the ecological processes governing niche specialization in a gradient of geography, seasonality, and land-use change, totalizing 324 soil samples, 43 habitat characteristics (abiotic factors), and 16 metabolic and co-occurrence patterns (biotic factors), in the Brazilian Atlantic Rainforest, a subtropical biome recognized as one the world's largest and most threatened hotspots of biodiversity. We observed no significant shifts in alpha diversity due to land-use change.Meanwhile, pairwise beta diversities and distance decays were lower in pastures than those observed for forest and no-till soils. Pasture communities showed a predominantly neutral model, regarding stochastic processes, with moderate dispersion, leading to biotic homogenization. Most no-till and forest microbial communities followed a niche-based model, with low rates of dispersal and weak homogenizing selection, indicating niche specialization or variable selection. Historical and evolutionary contingencies, as represented by soil type, season, and dispersal process were the main drivers of microbial assembly and processes at the local scale, markedly correlated with the occurrence of endemic microbes. Our results indicate that the patterns of assembly and their governing processes are dependent on the niche occupancy of the taxa evaluated (generalists or specialists). They are also more correlated with historical/evolutionary contingencies and the interactions among taxa (i.e. co-occurrence patterns) than the land-use change itself.

Changes in microbial biomass carbon (MBC) and microbial respiration in soils under five different land‐use systems were evaluated at a regional scale in Santa Catarina State, Southern Brazil, to assess the effects of land‐use change and geographical distribution on the microbial and environmental patterns related to soil carbon (C) dynamics. Results showed that, in the West mesoregion, changes in MBC were correlated to the sampling season in forest and pasture systems. In the Plateau mesoregion, however, a land‐use effect was observed, with MBC decreasing in no‐till and crop‐livestock integration systems. Forest and grassland sites presented the highest values of MBC and microbial activity, while grassland sites showed lower values of the metabolic quotient (qCO2) and higher values of the microbial quotient. The qCO2 was also lower in winter for all land‐use systems. The highest total and particulate organic carbon values were found in forest sites. Chemical–physical characteristics were also observed to be significantly correlated with microbiological variables related to soil microbial C dynamics. In conclusion, land‐use intensity, season, and location were found to be the main drivers of changes in microbial C dynamics.
