Skip spawning as a reproductive strategy in Antarctic fish species: the Antarctic silverfish (Pleuragramma antarctica) case study

Frontiers in Marine Science, 2015
The Antarctic silverfish Pleuragramma antarctica (Notothenioidei, Nototheniidae) is the most abundant pelagic fish inhabiting the frigid Antarctic coastal waters.

Twenty-First-Century Environmental Change Decreases Habitat Overlap of Antarctic Toothfish (Dissostichus mawsoni) and Its Prey. [PDF]

Glob Chang Biol
Antarctic toothfish are a commercially exploited upper‐level predator in the Southern Ocean, but knowledge on how Antarctic toothfish and its prey respond to environmental change remains incomplete. In this study, we employ the extended aerobic growth index to quantify changes in predator–prey viable habitat overlap in response to changes in ...

Sex Differentiation and Long-Distance Gene Flow in the Elusive Antarctic Fish <i>Aethotaxis mitopteryx</i>. [PDF]

Ecol Evol
This genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...

Coupling Genetic and Demographic Data to Reveal Dispersal Processes in Emperor Penguins. [PDF]

Ecol Evol
Dispersal is ubiquitous but dispersal rates, range, and behaviors remain difficult to measure. By developing new models combing demographic and genetic data, we propose to unravel species dispersal behaviors and apply our methodology to the emperor penguins, living in the most remote place on earth where measurements of dispersal are nonexistent.

Evidence for the Impact of Climate Change on Primary Producers in the Southern Ocean

Frontiers in Ecology and Evolution, 2021
Within the framework of the Marine Ecosystem Assessment for the Southern Ocean (MEASO), this paper brings together analyses of recent trends in phytoplankton biomass, primary production and irradiance at the base of the mixed layer in the Southern Ocean ...

Biological responses to change in Antarctic sea ice habitats

Frontiers in Ecology and Evolution, 2023
Sea ice is a key habitat in the high latitude Southern Ocean and is predicted to change in its extent, thickness and duration in coming decades. The sea-ice cover is instrumental in mediating ocean–atmosphere exchanges and provides an important substrate
