The opsin repertoire of the Antarctic krill Euphausia superba [PDF]

Marine Genomics, 2016
The Antarctic krill Euphausia superba experiences almost all marine photic environments throughout its life cycle. Antarctic krill eggs hatch in the aphotic zone up to 1000m depth and larvae develop on their way to the ocean surface (development ascent) and are exposed to different quality (wavelength) and quantity (irradiance) of light.

Drone‐Based Photogrammetry Provides Estimates of the Energetic Cost of Migration for Humpback Whales Between Antarctica and Colombia

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Monitoring the body condition of animals offers insights into their energetic needs, prey consumption, and vulnerability to environmental pressures. Southern hemisphere humpback whales ( Megaptera novaeangliae ) depend on Antarctic krill for their annual energy requirements.

Membrane Lipid Remodeling Strategies Regulate Fluidity for Acute Temperature Adaptation in Oysters

Evolutionary Applications, Volume 18, Issue 9, September 2025.
ABSTRACT Extreme climatic temperature stress induced by global warming poses a severe threat to the survival of marine invertebrates. The plasma membrane functions as a natural barrier and serves as the first responder to ambient temperature through dynamic modulation of its fluidity.

Trophic studies on the Okhotsk Sea herring in the 2000s (food composition, daily rations, assessment of consumption in the annual cycle)

Известия ТИНРО, 2016
Daily ration of the Okhotsk Sea herring is estimated as 3.9 % of the body weight in spring, 7.7 % in summer, 4.9 % in autumn, and 1.2 % in winter. Its mean annual consumption is assessed as 35.9 million t of prey, mainly zooplankton (97.3 % of the ration)

Environmental Features Associated With At‐Sea Sightings of Snow Petrel Pagodroma nivea in East Antarctica

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Over the last 70 years, seabird populations have declined by up to 70% across the globe. Compared to other seabirds, little is known about Snow Petrels and their marine habitat use—especially in East Antarctica. This study addresses the former knowledge gap while simultaneously comparing how outputs differ when data collection methods vary.

Seasonally migrating zooplankton strongly enhance Southern Ocean carbon sequestration

Limnology and Oceanography, Volume 70, Issue 8, Page 2208-2222, August 2025.
Abstract High‐latitude zooplankton can sequester millions of tons of carbon due to their seasonal migration from the surface ocean to depth, and their respiration and mortality during overwintering. This seasonal vertical migration pump (SVMP) efficiently removes carbon but not limiting nutrients such as iron from the surface layers.

Functional characterization of the circadian clock in the Antarctic krill, Euphausia superba

Scientific Reports, 2017
Antarctic krill (Euphausia superba) is a key species in Southern Ocean ecosystem where it plays a central role in the Antarctic food web. Available information supports the existence of an endogenous timing system in krill enabling it to synchronize ...
