Towards exhaustive community ecology via DNA metabarcoding

Area of Science:

• Ecology
• Molecular Biology
• Conservation Biology

Background:

• Comprehensive biodiversity data is essential for assessing global change effects on ecosystems.
• DNA metabarcoding advances biodiversity inventories but often lacks holistic community assessments.
• Current metabarcoding studies frequently use limited markers and taxonomic groups.

Purpose of the Study:

• To review emerging approaches for all-taxa biological inventories.
• To identify strengths and limitations of different DNA metabarcoding strategies.
• To suggest future research directions for broad-scale biodiversity analyses.

Main Methods:

• Overview of emerging DNA metabarcoding techniques.
• Analysis of primer strategies (specific, universal, combined).
• Discussion of advanced sequencing methods (multiplexing, shotgun, capture enrichment).

Main Results:

• Holistic biodiversity assessments using metabarcoding are rare but increasingly feasible.
• Combining diverse primers or advanced sequencing can enhance biodiversity coverage.
• Methodological advancements are needed for comprehensive ecological community reconstruction.

Conclusions:

• Emerging DNA metabarcoding approaches promise more exhaustive biodiversity inventories.
• Further development is required to overcome limitations in current methods.
• Holistic community reconstructions will improve understanding of biodiversity responses to environmental change.
