Abstract

Changes resulting from different tillage practices can affect the structure of microbial communities, thereby altering soil ecosystems and their functioning. The aim of this study was to explore and compare the physical, chemical properties and bacterial community composition of soils from different land use types (forest, grassland, vineyard, and arable field) in a small catchment. 16S rRNA gene-based amplicon sequencing was used to reveal the taxonomic diversity of summer and autumn soil samples taken from two different slope positions. The greater the anthropogenic impact was on the type of land use, the greater the change was in soil physical and chemical parameters. All sample types were dominated by the phyla Pseudomonadota, Acidobacteriota, Actinobacteriota, Bacteroidota and Verrucomicrobiota. Differences in the relative abundance of various bacterial taxa reflected the different land use types, the seasonality, and the topography. These diversity changes were consistent with the differences in soil properties.

巴拉顿高地（匈牙利）一个小型集水区受土地利用类型影响的土壤细菌群落

不同耕作方式造成的变化会影响微生物群落的结构，从而改变土壤生态系统及其功能。本研究旨在探索和比较一个小型集水区不同土地利用类型（森林、草地、葡萄园和耕地）土壤的物理、化学特性和细菌群落组成。研究采用基于 16S rRNA 基因的扩增子测序技术，揭示了取自两个不同斜坡位置的夏季和秋季土壤样本的分类多样性。人为因素对土地利用类型的影响越大，土壤物理和化学参数的变化就越大。所有类型的样本都以假单胞菌门、酸性杆菌门、放线菌门、类杆菌门和蛭石微生物门为主。各种细菌类群的相对丰度差异反映了不同的土地利用类型、季节性和地形。这些多样性变化与土壤特性的差异是一致的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
