Although invisible, fungi are recognized as the engines of a microbial powerhouse that drives soil ecosystem services

Abstract

Soil ecosystem services (SES) are the benefits that humans derive from soil. These services emerge from the complex interactions between biotic and abiotic processes within soil systems. They are vital for maintaining ecosystem resilience and ensuring long-term sustainability. Soil hosts a diverse group of biota, among them fungi play a crucial role in supporting and enhancing SES due to their remarkable adaptability and ability to thrive under unfavorable conditions. This review explores the multifaceted roles of fungi in SES, emphasizing their growing importance in strengthening ecosystem resilience and climate change adaptation. Fungi significantly contribute to the key ecosystem processes such as soil aggregation, organic matter (OM) decomposition, nutrients cycling, plant productivity, and carbon (C) sequestration. However, potential threats to fungal abundance and diversity could undermine these critical functions, highlighting the need for proactive measures to preserve fungal communities. The pivotal role of fungi in SES, including agricultural production and climate regulation, tailor them as indispensable microbial engines that shape and maintain ecosystem resilience. Emerging evidence suggests that soil fungal communities may become increasingly prominent under the future climate scenarios. Thus, understanding how fungal functional roles evolve in response to climate change is emergent for safeguarding SES and ensuring environmental sustainability. Furthermore, the co-occurrance of fungi with other soil organisms in supporting SES highlights the need to integrate diverse soil biota alongside fungi to promote sustainable SES. Collaborative efforts to comprehend and manage soil microbial communities are imperative for maintaining the long-term ecological stability of ecosystems.
