An Update on the Occurrence of Humpback Whale ( Megaptera novaeangliae ) Super‐Groups on the West Coast of South Africa

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT Humpback whale ( Megaptera novaeangliae ) super‐groups, comprising 20+, tightly aggregated, feeding individuals, form during the austral summer in the southern Benguela ecosystem off the west coast of South Africa. This phenomenon, observed since 2011, is thought to be linked to increased productivity from positive chlorophyll‐a anomalies ...

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.

Resource potential and maturity estimates of Euphausia superba in East Antarctica

Frontiers in Marine Science
The East Antarctic krill fisheries are spread across two Divisions of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), Division 58.4.1 between 80-150°E and Division 58.4.2 between 30-80°E.

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.

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.

Quantifying the Escape Mortality of Trawl Caught Antarctic Krill (Euphausia superba).

PLoS ONE, 2016
Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the

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.

Research Bias in Long‐Term Monitoring of Antarctic Nearshore Marine and Terrestrial Biota

Global Change Biology, Volume 31, Issue 8, August 2025.
Antarctic wildlife is under pressure from environmental changes and human activity, but how well is Antarctica's coastal biota being monitored? While over half of the long‐term monitoring studies spanned more than 10 years and/or included environmental data, they were limited in number, mostly focused on penguins and marine mammals, were unevenly ...
