Effect of elevated temperature on membrane lipid saturation in Antarctic notothenioid fish [PDF]
PeerJ, 2018 Homeoviscous adaptation (HVA) is a key cellular response by which fish protect their membranes against thermal stress. We investigated evolutionary HVA (long time scale) in Antarctic and non-Antarctic fish.

Genomic Signals of Local Adaptation Associated With Environmental Variables in <i>Eleginops maclovinus</i> From Northern Chilean Patagonia. [PDF]
Ecol EvolStudying evolutionary processes in the unique and understudied Patagonian fjord ecosystem is a challenging task for evolutionary ecologists. Genomic signals of local adaptation are present in a species from northern Chilean Patagonia. Polygenic selection drives local adaptation in Eleginops maclovinus. ABSTRACT Understanding the evolutionary mechanisms

Biology, 2022 Antarctic icefish are extraordinary in their ability to thrive without haemoglobin. We wanted to understand how the mitochondrial proteome has adapted to the loss of this protein. Metabolic pathways that utilise oxygen are most likely to be rearranged in

Photographic survey of benthos provides insights into the Antarctic fish fauna from the Marguerite Bay slope and the Amundsen Sea [PDF]
, 2013 We reviewed photographic images of fishes from depths of 381–2282 in Marguerite Bay and 405–2007 m in the Amundsen Sea. Marguerite Bay fishes were 33% notothenioids and 67% non-notothenioids.

Fish from the Southern Ocean: biodiversity, ecology and conservation challenges
Frontiers in Marine Science, 2015 According to the most recent census, the modern fauna of the Southern Ocean (SO) includes 374 fish species. Among them, a single group of closely related species, the suborder Notothenioidei, dominates, in terms of diversity, biomass and abundance ...

Gene Expression Profiling of Trematomus bernacchii in Response to Thermal and Stabling Stress
Fishes, 2022 The Antarctic continent is one of the most pristine environments on planet Earth, yet one of the most fragile and susceptible to the effects of the ongoing climate change.

A High-Resolution Microscopy System for Biological Studies of Cold-Adapted Species Under Physiological Conditions. [PDF]
Small MethodsRegions of the world permanently below 5 °C harbor significant biodiversity and understudied molecular mechanisms. This knowledge gap originates from the requirement for high‐resolution microscopy methods that maintain cold sample conditions while achieving subcellular resolution.

Karyotype and genome size of zoarcids and Notothenioids (Teleostei, perciformes) from the Ross Sea: Cytotaxonomic implications [PDF]
, 1996 In the absence of fossils, the origin of Notothenioidei, a perciform suborder dominating the fish fauna of the Southern Ocean, remains conjectural; some morphoecological evidence suggests relationships to zoarcoids.
