Abstract:
Monitoring marine mammal populations is essential to permit assessment
of population status as required by both national and international
legislation. Traditional monitoring methods often rely on visual and/or
acoustic detections from vessels and aircraft, but limitations including
cost, errors in the detection of some species and dependence on
taxonomic expertise, as well as good weather and visibility conditions
often limit the temporal and spatial scale of effective, long-term
monitoring programs. In recent years, environmental DNA (eDNA) has
emerged as a revolutionary tool for cost-effective, sensitive,
non-invasive species monitoring in both terrestrial and aquatic realms.
eDNA is a rapidly developing field and a growing number of studies have
successfully implemented this approach for the detection and
identification of marine mammals. Here, we review 21 studies published
between 2012 and 2021 that employed eDNA for marine mammal monitoring
including single species detection, biodiversity assessment and genetic
characterization. eDNA has successfully been used to infer species
presence (especially useful for rare, elusive or threatened species) and
to characterize the population genetic structure, although additional
research is needed to support the interpretation of non-detections.
Finally, we discuss the challenges and the opportunities that eDNA could
bring to marine mammal monitoring as a complementary tool to support
visual and acoustic methods.
Please, do not hesitate to get in touch if you have any question or
suggestion.
Best wishes,
