Global census of the significance of giant mesopelagic protists to the marine carbon and silicon cycles

open access: yesNature Communications
Thriving in both epipelagic and mesopelagic layers, Rhizaria are biomineralizing protists, mixotrophs or flux-feeders, often reaching gigantic sizes.

Microplastic interactions with North Atlantic mesopelagic fish [PDF]

open access: yesICES Journal of Marine Science, 2015
AbstractMicroplastics in the marine environment are well documented, and interactions with marine biota have been described worldwide. However, interactions with vertically migrating fish are poorly understood. The diel vertical migration of mesopelagic fish represents one, if not the largest, vertical migration of biomass on the planet, and is thus an

Low-latitude mesopelagic nutrient recycling controls productivity and export

open access: yesNature
Low-latitude (LL) oceans account for up to half of global net primary production and export1–5. It has been argued that the Southern Ocean dominates LL primary production and export6, with implications for the response of global primary production and ...

The Biology of Mesopelagic Fishes and Their Catches (1950–2018) by Commercial and Experimental Fisheries

open access: yesJournal of Marine Science and Engineering, 2021
Following a brief review of their biology, this contribution is an attempt to provide a global overview of the catches of mesopelagic fishes (of which 2.68 million tonnes were officially reported to the FAO) throughout the world ocean from 1950 to 2018 ...

Population ecology of mesopelagic fishes

open access: yes, 2022
This thesis focuses mainly on mesopelagic fishes, and mesopelagic fish species Maurolicus muelleri. Mesopelagic fishes are found in the oceanic twilight zone starting at the end of the euphotic zone down to approximately 1000 meters. The mesopelagic zone is found in all world oceans, and the fishes that inhabit them potentially occupy the highest ...

Different patterns of population structure and genetic diversity of three mesopelagic fishes in the Greek Seas

open access: yesMediterranean Marine Science, 2022
Mesopelagic fishes are among the most abundant groups of vertebrates on Earth. Despite their unique biological and ecological traits, research in this group has been particularly scarce.

Stranding of Mesopelagic Fishes in the Canary Islands

open access: yesAnimals, 2022
Most mesopelagic fishes perform large diel vertical migrations from the deep-sea zone to the surface. Although there is a trade-off between a higher food availability at the upper layers and an energy cost and predation risk, incursion towards the surface also implies a transport by currents, where the fish are exposed to a stranding risk on the coast.

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Temporal resolution in mesopelagic crustaceans

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Mesopelagic crustaceans occupy a dim–light environment that is similar to that of nocturnal insects. In a light–limited environment, the requirement for greater sensitivity may result in slower photoreceptor transduction and increased summation time.
