“…Our results (Table 1) also indicate that human effects can positively affect soil bacterial diversity at the global scale, corroborating findings at local [19,20] and regional scales [21]. Human movement may facilitate the invasion of diverse (soil) bacteria from one area to another, and increases in habitat patches driven by human land use may increase soil bacterial diversity.…”

“…For example, observed positive associations between bacterial diversity and annual mean temperatures suggests that global warming increases diversity [15,16]; moreover, experimental climate warming increases grassland soil bacterial diversity [17] and accelerates its temporal scaling [18]. Human activities (e.g., land use) are known to positively affect bacterial diversity at local [19,20] and regional scales (e.g., across Europe [21]).…”

Understanding global soil bacterial diversity is important because of the key roles soil bacteria play in the global ecosystem. Given the effects of environmental changes (e.g., climate change and human effect) on the diversity of animals and plants, effects on soil bacterial diversity are expected; however, they have been poorly evaluated to date. Thus, in this study, we focused on the soil dominant bacteria because of their global importance and investigated the effects of warming velocity and human activities on their diversity. Using a global dataset of bacteria, we performed spatial analysis to evaluate the effects, while statistically controlling for the potential confounding effects of current climate and geographic parameters with global climate and geographic data. It was demonstrated that the diversity of the dominant soil bacteria was influenced globally by warming velocity (showing significant increases) in addition to aridity index (dryness) and pH. The effects of warming velocity were particularly significant in forests and grasslands. An effect from human activity was also observed, but it was secondary to warming velocity. These findings provide robust evidence, and advance our understanding of the effects of environmental changes (particularly global warming) on soil bacterial diversity at the global scale.

“…Terrestrial ecosystems with higher temperatures often support higher primary productivity, provided that water is also available, resulting in unique vegetation types, e.g., forest vs. grasslands vs. bare surface and lack of vascular vegetation (Santruckova et al 2003, Currie et al 2004. The importance of ecosystem type as a driver of microbial communities have been recently highlighted by Szoboszlay et al (2017) and Terrat et al (2017), who found strong changes in the diversity and community composition of soil bacteria across different land uses. These factors may ultimately control the number of species that co-exist at a particular location (Currie and Paquin 1987, Turner 1987, Currie et al 2004.…”

“…In addition to these extreme physiological effects of temperature when comparing Australia with Antarctica, multiple direct and indirect effects on soil biodiversity and the abundance of ecological clusters are expected; such as changes in resource availability, aboveground diversity and changes in ecosystem types across continental Australia. The importance of ecosystem type as a driver of microbial communities have been recently highlighted by Szoboszlay et al (2017) and Terrat et al (2017), who found strong changes in the diversity and community composition of soil bacteria across different land uses. Much less is known on the role of ecosystem type in driving the biodiversity and ecological clusters of soil taxa within Australia.…”

The ecological drivers of soil biodiversity in the Southern Hemisphere remain underexplored. Here, in a continental survey comprising 647 sites, across 58 degrees of latitude between tropical Australia and Antarctica, we evaluated the major ecological patterns in soil biodiversity and relative abundance of ecological clusters within a co-occurrence network of soil bacteria, archaea and eukaryotes. Six major ecological clusters (modules) of co-occurring soil taxa were identified. These clusters exhibited strong shifts in their relative abundances with increasing distance from the equator. Temperature was the major environmental driver of the relative abundance of ecological clusters when Australia and Antarctica are analyzed together. Temperature, aridity, soil properties and vegetation types were the major drivers of the relative abundance of different ecological clusters within Australia. Our data supports significant reductions in the diversity of bacteria, archaea and eukaryotes in Antarctica vs. Australia linked to strong reductions in temperature. However, we only detected small latitudinal variations in soil biodiversity within Australia. Different environmental drivers regulate the diversity of soil archaea (temperature and soil carbon), bacteria (aridity, vegetation attributes and pH) and eukaryotes (vegetation type and soil carbon) across Australia. Together, our findings provide new insights into the mechanisms driving soil biodiversity in the Southern Hemisphere.

“…In our study, DOC content was significantly negatively correlated with soil pH and bulk density (Table 2). High soil pH can affect the DOC concentrations directly and can also influence DOC concentrations by affecting microbial species [54]. High bulk density indicates low soil porosity, which curbs the activity of soil biota and aerobic microbes [55], thus reducing DOC concentrations.…”

Soil organic carbon (SOC) concentration is closely related to soil quality and climate change. The objectives of this study were to estimate the effects of contemporary land use on SOC concentrations at 0-20 cm depths, and to investigate the dynamics of SOC in paddy-field soil and dry-land soil after their conversion from natural wetlands (20 and 30 years ago). We investigated the dissolved organic carbon (DOC), light fraction organic carbon (LFOC), heavy fraction organic carbon (HFOC), and other soil properties (i.e., moisture content, bulk density, pH, clay, sand, silt, available phosphorous, light fraction nitrogen, and heavy fraction nitrogen) in natural wetlands, constructed wetlands, fishponds, paddy fields, and soybean fields. The results indicated that the content of DOC increased 17% in constructed wetland and decreased 39% in fishponds, and the content of HFOC in constructed wetland and fishponds increased 50% and 8%, respectively, compared with that in natural wetlands at 0-20 cm. After the conversion of a wetland, the content of HFOC increased 72% in the paddy fields and decreased 62% in the dry land, while the content of DOC and LFOC decreased in both types. In the paddy fields, LFOC and HFOC content in the topmost 0.2 m of the soil layer was significantly higher compared to the layer below (from 0.2 to 0.6 m), and there were no significant differences observed in the dry land. The findings suggest that the paddy fields can sequester organic carbon through the accumulation of HFOC. However, the HFOC content decreased 22% after 10 years of cultivation with the decrease of clay content, indicating that paddy fields need to favor clay accumulation for the purpose of enhancing carbon sequestration in the paddy fields.
