Summary
Environmental DNA (eDNA) analysis shows promise for biomonitoring in Alaska's challenging environments. Despite challenges like funding and infrastructure, collaborations are advancing eDNA research for remote and Arctic monitoring.
Area of Science:
- Environmental DNA (eDNA) analysis
- Biomonitoring
- Remote sensing
Background:
- Alaska's unique logistical challenges for sampling.
- Emerging role of eDNA in biodiversity assessment.
- Need for comprehensive overview of eDNA research in the region.
Purpose of the Study:
- To evaluate the current state of eDNA research in Alaska.
- Identify barriers and opportunities for eDNA implementation.
- Provide a framework for advancing remote and Arctic biomonitoring.
Main Methods:
- Literature review of 22 peer-reviewed studies (2010-2025).
- Regional survey of 46 organizations (state, federal, academic, tribal, nonprofit).
- Analysis of published and ongoing eDNA projects.
Main Results:
- Most studies use eDNA metabarcoding for community, distribution, and biodiversity assessments.
- Key barriers include funding, infrastructure, assay availability, and protocol standardization.
- Cross-sector collaborations, including with subsistence harvesters, are emerging.
Conclusions:
- eDNA research in Alaska is growing, primarily using metabarcoding.
- Addressing implementation barriers is crucial for wider adoption.
- Collaborative, coproductive approaches are vital for remote and Arctic biomonitoring.
