Chlorophyll shading reduces zooplankton diel migration depth in a high-resolution physical–biogeochemical model [PDF]

Ocean Science
Zooplankton diel vertical migration (DVM) is critical to ocean ecosystem dynamics and biogeochemical cycles, by supplying food and injecting carbon into the mesopelagic ocean (200–800 m).

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

Journal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

The Dynamics of Location: Influence of Predation by Chaoborus Larvae on Rotifer Diel Vertical Migration Patterns [PDF]

, 2012
The locations of freshwater organisms in lakes are determined by the convergence of many competing factors. While predation pressure is one of these, also important are areas of food concentration and the physical and chemical constraints of a system ...

A new species of Peniculus (Copepoda: Siphonostomatoida) parasitizing mesopelagic myctophid fish: first discovery of colonization of the genus in deep water

Parasite, 2018
Peniculus hokutoae n. sp. is described on the basis of an ovigerous adult female parasitizing the caudal fin of the myctophid fish Symbolophorus evermanni (Gilbert, 1905), collected from Suruga Bay, Japan.

Marine heatwaves shape size‐dependent thermal exposure, habitat use and marine residency in Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Marine heatwaves (MHWs) are increasing in high‐latitude oceans, yet behavioural responses of anadromous fishes to these potential stressors during short marine feeding seasons remain poorly understood. We combined acoustic telemetry (internal temperature and depth) with satellite‐derived sea surface temperature data to quantify Arctic char ...

The selective advantage of diel vertical migration behavior in juvenile sockeye salmon and kokanee (Oncorhynchus nerka) [PDF]

, 1989
The widespread occurrence of diel vertical migration behavior in pelagic aquatic organisms suggests that there is a selective advantage of the behavior compared to a static vertical depth distribution in the water column.

Vertical distributions of chlorophyll in deep, warm monomictic lakes [PDF]

, 2010
The factors affecting vertical distributions of chlorophyll fluorescence were examined in four temperate, warm monomictic lakes. Each of the lakes (maximum depth >80 m) was sampled over 2 years at intervals from monthly to seasonal.

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

New 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 ...

Impact of ice covers on diel vertical migration of zooplankton in the Arctic marine environment [PDF]

, 2021
Diel vertical migration (DVM) of zooplanktonis a process of synchronized movement of the organisms from the mesopelagic zone up to the epipelagic zone at night and returning back during the day.

Assessing Zooplankton Communities' Influence on Particulate Organic Carbon Concentration

Geophysical 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.
