Microbial, holobiont, and Tree of Life eDNA/eRNA for enhanced ecological assessment

Area of Science:

• Environmental microbiology
• Molecular ecology
• Biodiversity assessment

Background:

• Microbial environmental DNA and RNA (eNA) are abundant in environmental samples.
• eNA signals often represent whole organisms, complementing data from larger species.
• Current eNA applications primarily focus on fragments, limiting holistic ecosystem understanding.

Purpose of the Study:

• To highlight the potential of microbial eNA for ecosystem assessments.
• To explore how microbial eNA can enhance biodiversity and ecosystem function monitoring.
• To advocate for integrating microbial data into environmental management frameworks.

Main Methods:

• Review of current eNA applications in environmental science.
• Conceptual framework for integrating microbial eNA into biotic indices.
• Discussion of holobiont and Tree of Life approaches for eNA analysis.

Main Results:

• Microbial eNA provides a comprehensive view of ecosystem composition and function.
• Integration of microbial eNA can significantly improve biodiversity assessments.
• Holistic approaches reveal complex microbial interactions crucial for ecosystem health.

Conclusions:

• Microbial eNA represents a transformative tool for environmental monitoring and management.
• Incorporating microbial data advances understanding of ecosystem dynamics and interdependencies.
• Future applications include environmental management, conservation, and food production.
