Antarctic notothenioids dominate the fish fauna of the Southern Ocean. Evolution for millions
of years at cold and stable temperatures has led to the acquisition of numerous biochemical …

The ability of marine organisms to thrive over wide ranges of environmental stressors that
perturb structures of proteins, nucleic acids, and lipids illustrates the effectiveness of …

Antioxidant defense system (ADS) and oxidative stress parameters were evaluated in the
Antarctic fish Notothenia rossii and N. coriiceps exposed to increasing temperature …

Anthropogenic CO2 is rapidly causing oceans to become warmer and more acidic,
challenging marine ectotherms to respond to simultaneous changes in their environment …

As climate-driven heat waves become more frequent and intense, there is increasing
urgency to understand how thermally sensitive species are responding. Acute heating …

The objective of the present study was to assess the effect of short-term (2–144 h) heat
stress (8° C) on energy production processes and antioxidant defense systems in the …

Background As global climate change progresses, the Southern Ocean surrounding
Antarctica is poised to undergo potentially rapid and substantial changes in temperature and …

The aim of this study was to determine whether endemic Antarctic nototheniid fish are able
to adjust their liver antioxidant defence system in response to the temperature increase. The …

The adaptations used by notothenioid fish to combat extreme cold may have left these fish
poorly poised to deal with a changing environment. As such, the expected environmental …

Increases in atmospheric CO 2 levels and associated ocean changes are expected to have
dramatic impacts on marine ecosystems. Although the Southern Ocean is experiencing …
