Population genomics analysis holds great potential for informing conservation of endangered populations. We focused on a controversial case of European whitefish ( Coregonus spp.) populations. The endangered North Sea houting is the only coregonid fish that tolerates oceanic salinities and was previously considered a species ( C. oxyrhinchus ) distinct from European lake whitefish ( C. lavaretus ). However, no firm evidence fo...

Documented biodiversity associated with offshore oil and gas platforms has led to growing interest in their potential conversion to artificial reefs under Rigs-to-Reefs (RTR) programmes following decommissioning. In this study, we assessed fish assemblages associated with offshore platforms in Qatar’s Al Khalij oilfield for the first time, using remotely operated vehicle (ROV) video surveys. Species diversity, abundance, and b...

Citizen science involves non-professionals assisting with scientific research, contributing data, and conducting experiments under professional guidance. In this paper, we describe the citizen science project DNA & life , based at the Natural History Museum of Denmark, which actively engages high school students in both fieldwork and advanced laboratory analyses by collecting and analyzing eDNA samples from marine environments...

Marine biodiversity is threatened by human activities. To understand the changes happening in aquatic ecosystems and to inform management, detailed, synoptic monitoring of biodiversity across large spatial extents is needed. Such monitoring is challenging due to the time, cost, and specialized skills that this typically requires. In an unprecedented study, we combined citizen science with eDNA metabarcoding to map coastal fish...

Conservation and management of marine biodiversity depends on biomonitoring of marine habitats, but current approaches are resource‐intensive and require different approaches for different organisms. Environmental DNA (eDNA) extracted from water samples is an efficient and versatile approach to detecting aquatic animals. In the ocean, eDNA composition reflects local fauna at fine spatial scales, but little is known about the e...
