Systems of reciprocity in human–ocean relationships: Across time, place, language and culture

open access: yesPeople and Nature, EarlyView.
Abstract In the face of large‐scale marine environmental challenges, solutions that meaningfully capture the complexity of socio‐cultural and economic factors contributing to such issues—and their solutions—are urgently needed. This scoping review explores examples of reciprocity in human–ocean relationships to inform the conceptual underpinning and ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.
