Arctic nekton uncovered by e DNA metabarcoding: Diversity, potential range expansions, and pelagic‐benthic coupling
Abstract The Arctic Ocean is home to a unique fauna that is disproportionately affected by global warming but that remains under‐studied. Due to their high mobility and responsiveness to global warming, cephalopods and fishes are good indicators of the reshuffling of Arctic communities. Here, we est...

Abstract The Arctic Ocean is home to a unique fauna that is disproportionately affected by global warming but that remains under‐studied.
