Myctophids are the most abundant and diverse mesopelagic fishes in the Southern Ocean.
They are a conduit of energy between primary consumers and higher marine predators, and …

Southern Ocean ecosystems are globally important and vulnerable to global drivers of
change, yet they remain challenging to study. Fish and squid make up a significant portion of …

Recent estimates suggest that the mesopelagic zone could contain a total fish biomass of 2-
19.5 gigatonnes, roughly equivalent to 100 times the annual catch of all existing fisheries. In …

Dietary and predator–prey studies are more frequently relying on DNA metabarcoding
methods, typically achieving results that have a better taxonomic resolution (eg, species …

Advances in high‐throughput sequencing (HTS) are revolutionizing monitoring in marine
environments by enabling rapid, accurate and holistic detection of species within complex …

Introduction Mesopelagic fishes play a central role in the transfer of energy through open-
ocean food webs, particularly in the Southern Ocean where they are both important …

Abstract Information about the dietary composition of a species is crucial to understanding
their position and role in the food web. Increasingly, molecular approaches such as DNA …

Lanternfishes (Myctophidae) are key components of mesopelagic fish communities globally.
In the Southern Ocean, incomplete information on myctophid diets limits our understanding …

DNA metabarcoding and morphological taxonomic (microscopic) analysis of the gut
contents was used to examine diet diversity of seven species of fishes collected from …

The importance of microbes for the functioning of oceanic food webs is well established, but
their relevance for top consumers is still poorly appreciated. Large differences in individual …
