The Importance of Mesozooplankton Diel Vertical Migration for Sustaining a Mesopelagic Food Web

open access: yesFrontiers in Marine Science, 2019
We used extensive ecological and biogeochemical measurements obtained from quasi-Lagrangian experiments during two California Current Ecosystem Long-Term Ecosystem Research cruises to analyze carbon fluxes between the epipelagic and mesopelagic zones ...

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

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

open access: yes, 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 ...

The nightscape of the Arctic winter shapes the diving behavior of a marine predator

open access: yesScientific Reports
Predator–prey interactions in marine ecosystems are dynamically influenced by light, as demonstrated by diel vertical migrations of low-trophic level organisms.

Sensitivity of fish diel vertical migration depths to future changes in the Pacific Ocean oxygen minimum zone

open access: yesFrontiers in Marine Science
Diel vertical migrations in the ocean play a key role in predator-prey dynamics and the functioning of the biological carbon pump. However, changes in ocean conditions including warming and deoxygenation threaten to significantly perturb vertical ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

A new Activity Monitor for Aquatic Zooplankter (AMAZE) allows the recording of swimming activity in wild-caught Antarctic krill (Euphausia superba)

open access: yesScientific Reports
Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its synchronized behavioral patterns, such as diel vertical migration (DVM ...

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane
