Abstract

Forest wildfires are considered one of the three main routes to recycle organic matter and nutrients in terrestrial ecosystems. Consequently, physicochemical and biological soil properties, as well as the mineralogical composition, are affected by wildfires and its recurrence. In recent years the increase in the occurrence and frequency of wildfires, the impact on the recovery of ecosystems has generated a growing interest in studying the effects of wildfire on mineralogy and nutrients (WMN) interactions. Multiple investigations have been approached from different points of view to understand the impacts of wildfires that reduce the resilience of native forests and plantations with dramatic consequences for the recovery and conservation of these ecosystems. However, no attempt has been made to provide a whole picture of the research status on mineralogy and nutrients affected post wildfire events from a bibliometric perspective. Thus, this work aims to evaluate its thematic evolution through bibliometric analysis with software Vosviewer. A detailed bibliometric analysis, including the analysis of 530 articles published in 211 selected academic journals during 1984–2020. The results demonstrate that Forest ecology and management, Geoderma and International journal of wildland fire are the leading journals in the WMN field. United States Department of Agriculture (USDA) had the highest total documents and citations, followed by Consejo Superior de Investigaciones Cientificas (CSIC). In addition, USA, Spain, and France are the top three research centers for this topic. Moreover, Certini G., Cerda A., and Mataix-Solera J. were the top three authors, while Johnson, D. ranked the first depending on citations per publication. In terms of co-occurrence of keyword analysis, the results indicate that nitrogen, phosphorus and carbon have gained close attention from scholars, while mineralogy and microbial biomass as such is less studied. Perspectives on future studies are also given.
