The multidimensionality of soil macroecology

Area of Science:

• Ecology
• Soil Science
• Biodiversity Research

Background:

• Recent surge in soil macroecological studies reveals global drivers of soil biodiversity.
• A prior study introduced spatial three-dimensionality in soil macroecology, considering organism size and scale.
• Existing research primarily focuses on descriptive patterns of soil biodiversity.

Purpose of the Study:

• To extend the concept of dimensionality in soil macroecology by incorporating biological, physical, and societal aspects.
• To transition soil macroecology from pattern description to mechanistic understanding and predictive science.
• To inform policy for effective nature and conservation management actions.

Main Methods:

• Conceptual expansion of soil macroecology to include temporal dynamics and multiple facets of biodiversity.
• Integration of ecosystem functions and human-soil biodiversity feedback effects.
• Emphasis on experimental approaches (local and global) to verify causal relationships.

Main Results:

• Proposes a multidimensional framework for soil macroecology, including spatial, temporal, biological, physical, and societal dimensions.
• Highlights the need to integrate diverse biodiversity facets (body size, traits, taxa) with ecosystem functions.
• Stresses the importance of human-soil interactions and their feedback loops.

Conclusions:

• A multidimensional perspective is essential for advancing soil macroecology as a predictive science.
• Future research and funding should prioritize these expanded dimensions.
• Incorporating these dimensions is crucial for global soil biodiversity monitoring and conservation policy.
