Climate drives long-term change in Antarctic Silverfish along the western Antarctic Peninsula [PDF]
Communications Biology, 2022 Corso et al. employ a novel 25-year time series to show how variability in sea ice coverage and ocean temperatures impact larval abundance of an important forage fish, the Antarctic Silverfish.

Life strategy of Antarctic silverfish promote large carbon export in Terra Nova Bay, Ross Sea [PDF]
Communications BiologyAntarctic silverfish Pleuragramma antarcticum is the most abundant pelagic fish in the High Antarctic shelf waters of the Southern Ocean, where it plays a pivotal role in the trophic web as the major link between lower and higher trophic levels.

Spatiotemporal Distribution of Antarctic Silverfish in the Ross Sea, Antarctica
FishesAntarctic silverfish (Pleuragramma antarcticum) play a crucial intermediary role in connecting top predators and krill in the food web of the Antarctic Ocean. Despite their crucial role, research on their abundance is lacking. In this study, we estimated

Along-shelf connectivity and circumpolar gene flow in Antarctic silverfish (Pleuragramma antarctica). [PDF]
Sci Rep, 2018 The Antarctic silverfish (Pleuragramma antarctica) is a critically important forage species with a circumpolar distribution and is unique among other notothenioid species for its wholly pelagic life cycle. Previous studies have provided mixed evidence of

The Arrangement of the Peripheral Olfactory System of Pleuragramma antarcticum: A Well-Exploited Small Sensor, an Aided Water Flow, and a Prominent Effort in Primary Signal Elaboration [PDF]
Animals, 2022 The olfactory system is constituted in a consistent way across vertebrates. Nasal structures allow water/air to enter an olfactory cavity, conveying the odorants to a sensory surface.

Regional Differences in the Diets of Adélie and Emperor Penguins in the Ross Sea, Antarctica [PDF]
Animals, 2021 To identify the dietary composition and characteristics of both Adélie (Pygoscelis adeliae) and Emperor (Aptenodytes forsteri) penguins at four breeding sites, we performed stable carbon (δ13C) and nitrogen (δ15N) isotope analysis of down samples taken ...

Beneath the Antarctic sea-ice: Fine-scale analysis of Weddell seal (Leptonychotes weddellii) behavior and predator-prey interactions, using micro-sonar data in Terre Adélie. [PDF]
Ecol Evol, 2023 We describe fine‐scale lactating Weddell seals' foraging ecology, providing high‐resolution diving behavior and associated prey encounters using new sonar tags. Females displayed a mix of capital and income‐breeding strategies. Feeding activity was mostly benthic (contrary to non‐lactation period), reduced, and spatially limited.

Assessing the influence of blubber stratification on the estimation of diet in phocid seals using the MixSIAR model [PDF]
Scientific ReportsBlubber stratification can significantly impact diet estimation, as using the inner or outer blubber layer may lead to different results depending on the degree of stratification present.
