State of Satiation Partially Regulates the Dynamics of Vertical Migration
Frontiers in Marine Science, 2021 Vertical migrations into shallower waters at night are beneficial for migrators as they reduce predation risk and allow migrators to encounter a higher density of prey.

Modeling marine zooplankton and micronekton
, 2016 Le zooplancton et le micronecton sont les deux premiers échelons animaux de la chaine trophique marine. Bien que de tailles très différentes (200μm à 2mm pour le zooplancton, 2 à 20cm pour le micronecton), ces deux groupes d'espèces variées partagent un comportement singulier : les migrations nycthémérales.

Mesoscale Eddies Structure Mesopelagic Communities
Frontiers in Marine Science, 2020 Mesoscale eddies play a key role in structuring open ocean ecosystems, affecting the entire trophic web from primary producers to large pelagic predators including sharks and elephant seals.

Seasonal oceanography from physics to micronekton in the south-west Pacific [PDF]
Deep Sea Research Part II: Topical Studies in Oceanography, 2015 Tuna catches represent a major economic and food source in the Pacific Ocean, yet are highly variable. This variability in tuna catches remains poorly explained. The relationships between the distributions of tuna and their forage (micronekton) have been mostly derived from model estimates.

Frontiers in Marine Science, 2021 We examined spatial patterns in diet, trophic niche width and niche overlap for chum, pink and sockeye salmon across the North Pacific during 1959–1969. This is a baseline period before major hatchery enhancement occurred coinciding with a negative phase

Gregarious behaviour in crustacean micronekton (Euphausiacea, Mysidacea)
, 1988 Certain species of pelagic euphausiids and hyperbenthic mysids (Crustacea) show highly integrated social behaviour comparable in many aspects to schooling in higher marine organisms such as fish, squid and mammals. The ethology, form, maintenance, occurrence and population structure of aggregations of three species of euphausiid and six species of ...

Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]
, 2017 Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...
