We have developed a global biogeographic classification of the mesopelagic zone to reflect
the regional scales over which the ocean interior varies in terms of biodiversity and function …

Deep-sea fishes inhabit∼ 75% of the biosphere and are a critical part of deep-sea food
webs. Diet analysis and more recent trophic biomarker approaches, such as stable isotopes …

Recent studies suggest that previous estimates of mesopelagic biomasses are severely
biased, with the new, higher estimates underlining the need to unveil behaviourally …

Many large marine predators make excursions from surface waters to the deep ocean below
200 m. Moreover, the ability to access meso-and bathypelagic habitats has evolved …

Many predator species make regular excursions from near-surface waters to the twilight
(200 to 1,000 m) and midnight (1,000 to 3,000 m) zones of the deep pelagic ocean. While …

The ocean plays a crucial role in the functioning of the Earth System and in the provision of
vital goods and services. The United Nations (UN) declared 2021–2030 as the UN Decade …

Establishing the foundations for a sustainable use of deep‐sea resources relies on
increasing knowledge on this inaccessible ecosystem, which is challenging with traditional …

In this investigation we analysed the changes in fish species occurrences and relative
abundances across the tropical and equatorial Atlantic, and their vertical distribution …

Food web linkages, or the feeding relationships between species inhabiting a shared
ecosystem, are an ecological lens through which ecosystem structure and function can be …

Animal biodiversity in the ocean's vast mesopelagic zone is relatively poorly studied due to
technological and logistical challenges. Environmental DNA (eDNA) analyses show great …
