Flexible behaviour in a mesopelagic fish (Maurolicus muelleri)

open access: yesICES Journal of Marine Science, 2021
Abstract Variability of mesopelagic scattering layers is often attributed to environmental conditions or multi-species layer composition. Yet, little is known about variation in behaviour among the individuals forming scattering layers.

First Report on the Diet of the Angolan Flying Squid (Todarodes angolensis) in New Zealand Waters

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The Angolan flying squid (Todarodes angolensis) is a southerly distributed, large‐bodied ommastrephid preyed upon by many large marine vertebrates such as the southern elephant seal and deep‐sea squalid sharks. Here, we report its diet in New Zealand waters for the first time, identifying prey items from the stomach contents of 58 adults using ...

Lipid classes of unsorted mesopelagic catch from in the Northeast Atlantic

open access: yes, 2021
During three cruises in the Mid Atlantic Ridge area in 2016 and 2017, we collected samples of mesopelagic species down to a depth of 600 m and analysed wax esters, triglycerides, free fatty acids, cholesterol and phospholipids (g/100 g oil) of four catch

Chasing after Non-cyanobacterial Nitrogen Fixation in Marine Pelagic Environments

open access: yesFrontiers in Microbiology, 2017
Traditionally, cyanobacterial activity in oceanic photic layers was considered responsible for the marine pelagic dinitrogen (N2) fixation. Other potentially N2-fixing bacteria and archaea have also been detected in the pelagic water column, however, the

Assessing Zooplankton Communities' Influence on Particulate Organic Carbon Concentration

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Zooplankton play a key role in setting the particulate organic carbon (POC) distribution in the ocean, but this role remains poorly quantified on large scales due to the complexity of zooplankton ecosystems and the sparsity and variability of observations.

Deep‐pelagic fishes: Demographic instability in a stable environment

open access: yesEcology and Evolution
Demographic histories are frequently a product of the environment, as populations expand or contract in response to major environmental changes, often driven by changes in climate.

SAR202 Genomes from the Dark Ocean Predict Pathways for the Oxidation of Recalcitrant Dissolved Organic Matter

open access: yesmBio, 2017
Deep-ocean regions beyond the reach of sunlight contain an estimated 615 Pg of dissolved organic matter (DOM), much of which persists for thousands of years.

Running the Gauntlet: Assessing the Threats to Vertical Migrators

open access: yesFrontiers in Marine Science, 2020
Diel vertical migrations (DVM) by zooplankton and nekton are driven by the selective advantage of avoiding visually cued predators near the surface during the hours of daylight.

Instance of a Heteroplasmic Mitogenome in Alvinocaridid Shrimp Mirocaris fortunata (Martin & Christiansen 1995) Found at the Moytirra Deep‐Sea High‐Temperature Hydrothermal Vent Field

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
First complete mitochondrial genome of the deep‐sea hydrothermal vent shrimp Mirocaris fortunata (Alvinocarididae) from shotgun sequencing data on an individual tail tissue. The 15,923‐bp‐long sequence displays 98.72% pairwise identity with its closest relative, Mirocaris indica.

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
