“…Salvage logging is the most common post-fire management strategy in Mediterranean coniferous forests. Intensive salvage logging trigger soil degradation processes: soil compaction, delay of vegetation recovery (Wagenbrenner et al, 2016;García-Orenes et al, 2017), disturbance of nutrient cycling (Pereg et al, 2018), alteration in carbon fluxes (Serrano-Ortiz et al, 2011;Hartmann et al, 2014), and disruption in soil biodiversity directly or indirectly, e.g., disturbing the deadwood-dependent species (Thorn et al, 2020), reducing the cover of biocrust-forming mosses (García-Carmona et al, 2020), or altering the soil microbial communities (García-Carmona et al, 2021a). Soils can suffer persistent alterations, ultimately reducing forest productivity and ecosystem functionality (Hartmann et al, 2014;Chen et al, 2015).…”

“…On the other hand, burnt wood is a biological legacy of key relevance in burned forests (Thorn et al, 2018). The burnt wood act as a barrier for sediments against water erosion, constitutes a stock of nutrients that slowly fertilize soil through decomposition, and ameliorates the stress conditions by increasing soil moisture, enabling vegetation and microbial development and sustaining biodiversity and ecosystem services (Baldrian, 2017;Thorn et al, 2018;García-Carmona et al, 2021a;Juan-Ovejero et al, 2021). However, timber activities in Mediterranean forests are important from a social perspective, being non-interventionism is highly controversial .…”

Although Mediterranean ecosystems are adapted to fire disturbances, soils are prone to degradation. Therefore, post-fire forest management is a critical step for ecosystem recovery: it can either reduce soil degradation or add a new disturbance. Post-fire management in Mediterranean burnt forests includes interventions with contrasting approaches, including the management of burnt trees, soil protection, or practices devoted to ecosystem restoration via the improvement of components or processes in the affected ecosystem. The consequences of forest management on soils are complex, thereby, in the context of the intensification of fire events and climate change, understanding the response of key soil components in managed ecosystems is critical for prioritizing soil conservation. One interesting component in the early post-fire stages is moss biocrust. The rapid colonization of biocrust-forming mosses in early successional stages post-disturbance stabilizes soils in their most vulnerable period. However, it is completely unknown further implications as active agents in the recovery and resilience of soils, in the transient stage before vascular vegetation regrowth. In combination with the biocrust, the response of soil microbial communities to forest management is crucial for evaluating the soil recovery progress, given their active role in fundamental ecosystem functions. The additive consequences of fires and forest management on biocrust emergence or microbial composition and functionality are usually neglected in the investigation of post-fire systems, although of major relevance to support strategies to preserve soils against functionality loss.

“…Bacteria, archaea and eukaryotes in the rhizosphere microbial community were essential bioactive components of forest ecosystems [ 7 ]. It was found that maintaining the dynamic balance and diversity of the rhizosphere microbial community structure will helped to protect the co-ordination mechanisms of the whole ecosystem and buffered negative impacts [ 8 ]. Philippot et al confirmed that the rate of the denitrification process decreases with the loss of soil microorganisms [ 9 ].…”

Malus sieversii (Ldb.) Roem. is the original species of modern cultivated apple and a key national essential conservation plant in China. In recent years, degradation and death of wild apple has been exacerbated by imbalances in the rhizosphere micro-ecosystems of wild apple forests due to soil nutrient loss, grazing, climate change and pest and disease outbreaks. However, the structure, diversity and response to environmental factors of wild apple rhizosphere microbial communities are so far unclear. In this study, the rhizosphere bacterial and eukaryotic communities of M. sieversii (Ldb.) Roem. in eight regions of the Yili River were analyzed using 16S/18S rDNA high-throughput sequencing technology. The results indicated that the bacterial operational taxonomic units (OTUs), Shannon index, and community composition were significantly lower in regions A, E, and F than in other regions. By contrast, the dominant eukaryotic communities in all regions were relatively similar in composition and differed less than the relative abundance of bacterial communities. Geographical and climatic distance were found to be key factors influencing the composition and diversity of wild apple rhizosphere microbial communities through mantel analysis. Moreover, these factors above were more correlated with bacterial diversity than with eukaryotes. This study identified the structure of wild apple rhizosphere microbial communities in Xinjiang and their interaction mechanisms under geographical and environmental gradients. It provides guidance for the sustainable management and ecological construction of wild apple forests in China.

“…Precisely, metabarcoding has identified how disturbance events of natural and anthropogenic origin have a significant effect on the soil mycobiome of forests (Bowd et al, 2022;Martín-Pinto et al, 2023). This methodology of mycobiota diversity analysis has already been used in Mediterranean forest, being described as an effective way for the real knowledge of microbial diversity and functionality (Adamo et al, 2021a,b), also in situations of disturbance, such as fire (García-Carmona et al, 2021) or climate change (Diez-Hermano et al, 2022).…”

IntroductionForests in the Mediterranean basin are currently in decline. Their resilience has been eroded as a result of climate change and anthropogenic impacts, making them vulnerable to increasingly frequent episodes of drought, fire and the spread of pests and diseases. The impact of these natural and anthropogenic events on soil biodiversity is of particular concern, as the soil fungal community plays a key role in ecosystem homeostasis.Objectives and methodsIn order to analyse the relationship between soil health status and fungal diversity, soil samples were collected from declining Mediterranean forests of Castanea sativa (chestnut), Quercus ilex (holm oak), Quercus suber (cork oak) and Quercus pyrenaica (Pyrenean oak). A metabarcoding study was carried out by sequencing the ITS genomic region.ResultsA total of 674 fungal genera were found. It has not been possible to explain the differences in health status from the fungal genera found exclusively on declining forest soils, as none of them have been described as pathogenic. Healthy chestnut soils were characterized by a high alpha diversity and a higher abundance of the genus Metarhizium. No differentially abundant genera were found in any of the other forest species tested. Declining chestnut soils harbored more abundance of ectomycorrhizae and soil saprotrophs than healthy samples. Ectomycorrhizae were the dominant lifestyle in all oak species regardless of health status, whereas arbuscular mycorrhizae were preferentially found in declining cork oak soils.DiscussionThis work highlights the resilience of fungal communities of soil against decline and highlights the need to further investigate its relationship with the forest’s ability to cope with the challenges of climate change.
