Abstract
This study investigated the factors affecting bacterial diversity in purplish and calcareous soils under the same vegetation type. The results showed that obvious differences in pH, water content, total phosphorus (TP), free iron oxide (Fed) and amorphous iron oxide (Feox) existed between the two soils. The bacterial Shannon indexes of the two soils varied significantly, and Shannon index of purplish soil were higher than that of calcareous soils. The co-occurring network structures in two soil bacterial communities showed obvious variations, with higher edge counts, average degrees and clustering coefficients in calcareous soils than that in purple soils. The key species group identified in the two soils was Acidobacteria; belonging to the family Thermoanaerobaculaceae in purplish soil, and to the family Vicinamibacterales in calcareous soil. Also, the results of multivariate stepwise linear regression showed that Feox was a significant explanatory factor for changes in bacterial diversity (68.8%, P < 0.01) compared to other physical and chemical factors. Overall, our study indicated that soil parent material may be an important factor influencing soil bacterial communities.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
