Bibliographic survey of microbial diversity from Chilean soils

This dataset is a recopilation of research works published from 1975 to 2023 presenting original studies of soil microbial diversity in Chile. The considered microorganisms are bacteria, archaea, and fungi. The studies selected here focused on the diverse environmental biomes represented in Chile, from arid desert and salt flats in the North, to cultivated lands and forests in the medium South, and steppes and glaciers in the extreme South down to the Antarctic peninsula. The dataset includes different methodological approaches such as cultivation, sequencing, metabarcoding, metagenomics, as well as functional characterization of microbial communities. The main objectives of this work are (i) to describe quantitatively and qualitatively the existing research effort for microbial diversity understanding in Chilean soils (i.e., number of studies, type of methodological approaches, and origin of funding), (ii) to compare the extent of research in the different Chilean regions (including the Antarctic Peninsula) and along time since 1975, and (iii) to identify the main research scopes and current knowledge gaps in soil biodiversity in Chile and Antarctic Peninsula. The studies included in this dataset adressed different main concerns, as follows: potential biotechnological applications of soil microorganisms; impact of climate change on soil microorganisms; microbial diversity of extreme environments; identification of new species; effect of disturbances on soil microorganisms; insights in the functionnal capacities of microbial diversity; biogeographic distribution of soil microorganisms.

本数据集汇编了自1975年至2023年间发表的关于智利土壤微生物多样性的原创研究作品。所考虑的微生物包括细菌、古菌和真菌。所选研究聚焦于智利境内多样化的环境生物群落，涵盖从北部的干旱沙漠和盐沼，至中南部耕作土地和森林，直至极南部的草原和冰川，直至南极半岛。数据集涵盖了多种方法论途径，如培养、测序、宏条形码、宏基因组学，以及微生物群落的机能特征。本工作的主要目标包括：(i) 定量与定性描述智利土壤微生物多样性研究领域的现有努力（即研究数量、方法论途径类型及资金来源），(ii) 比较自1975年以来不同智利地区（包括南极半岛）的研究范围，以及随时间的变化，和(iii) 识别智利及南极半岛土壤生物多样性的主要研究方向和当前知识空白。本数据集包含的研究针对以下不同主要问题：土壤微生物的生物技术应用潜力；气候变化对土壤微生物的影响；极端环境中的微生物多样性；新物种的鉴定；干扰对土壤微生物的影响；微生物多样性机能能力的见解；土壤微生物的生物地理分布。
