Insights into the resistance and resilience of the soil microbial community

2012 | Bryan S. Griffiths & Laurent Philippot
Soil microbial communities play a crucial role in maintaining essential ecosystem services, such as nutrient cycling and soil structure. Understanding the resistance and resilience of these communities to environmental disturbances is vital for preserving soil health. Resistance refers to the ability of a microbial community to withstand a disturbance, while resilience is the capacity to recover from it. These concepts are influenced by various factors, including soil physico-chemical properties, microbial diversity, and the nature of the disturbance. Studies have shown that soil stability is not solely determined by microbial diversity but also by other factors such as soil structure, aggregation, and substrate quality. The resilience of soil microbial communities can be affected by the type of disturbance, with some disturbances leading to greater resilience than others. For example, microbial communities in soils with high organic matter content tend to be more resilient to disturbances like heat or copper exposure. The response of soil microorganisms to environmental disturbances varies depending on the type of disturbance and the soil's history. For instance, soils contaminated with heavy metals may show reduced resilience to further disturbances, while soils with high organic matter content may show increased resilience. Additionally, the resilience of microbial communities can be influenced by their ability to adapt to environmental stressors, such as heat or chemical exposure. The role of soil properties in determining microbial resilience is significant. Soil structure, organic matter content, and clay content all influence the resilience of microbial communities. For example, soils with high organic matter content tend to be more resilient to disturbances like heat or copper exposure. Similarly, soils with high aggregation and good structure are more resilient to physical disturbances like compaction. In conclusion, the resilience and resistance of soil microbial communities are influenced by a complex interplay of factors, including soil properties, microbial diversity, and the nature of the disturbance. Understanding these factors is essential for maintaining soil health and ensuring the continued provision of essential ecosystem services.Soil microbial communities play a crucial role in maintaining essential ecosystem services, such as nutrient cycling and soil structure.
