Abstract

Natural England and JNCC commissioned NatureMetrics to produce a review and protocol for DNA-based marine benthic sampling. This was in the context of DNA metabarcoding and long-term monitoring of benthic species and habitats of conservation importance in UK Marine Protected Areas. For the same benthic DNA sampling method to be used across marine surveys with different spatial and temporal scales, the standardization of DNA sample collection and processing is essential.

DNA-based biomonitoring has the potential to generate more biodiversity data for less effort compared with conventional monitoring methods. DNA-based monitoring usually gives much larger, more comprehensive and consistent datasets than traditional, morphological assessments. This is especially important for monitoring over long temporal scales. It also offers a pathway to obtaining data from robust biological indicators that can measure changes in response to environmental and anthropogenic impacts and mitigation measures.

This review outlines the current state of the field in DNA-based marine benthic biomonitoring to enable scientists and managers to make informed decisions and to maximise the benefits of this new technology. It is based on an extensive literature review, and on NatureMetrics’ practical experience.
