Stress response in the Antarctic teleosts (Notothenia neglecta Nybelin and N. rossii Richardson)
Read more of: Stress response in the Antarctic teleosts (Notothenia neglecta Nybelin and N. rossii Richardson)Blood chemistry and haematological parameters have been determined in the Antarctic teleosts, Notothenia neglecta Nybelin and Notothenia rossii Richardson at 2° C. Samples were taken using chronically implanted dorsal aortic […]

Studies of conjugate plasma convection in the vicinity of the Harang discontinuity
Read more of: Studies of conjugate plasma convection in the vicinity of the Harang discontinuityTwo case studies are presented of the large-scale nightside ionospheric plasma convection observed simultaneously in the two polar regions using HF backscatter radars. The case studies occur during geomagnetically quiet […]

Atmospheric influences on the anomalous 2016 Antarctic sea ice decay
Read more of: Atmospheric influences on the anomalous 2016 Antarctic sea ice decayIn contrast to the Arctic, where total sea ice extent (SIE) has been decreasing for the last three decades, Antarctic SIE has shown a small, but significant, increase during the […]

Plasticity in the foraging behavior of male Southern Rockhopper Penguins (Eudyptes chrysocome) during incubation in the Falkland/Malvinas Islands
Read more of: Plasticity in the foraging behavior of male Southern Rockhopper Penguins (Eudyptes chrysocome) during incubation in the Falkland/Malvinas IslandsEnvironmental changes often affect the persistence of species or populations at different spatial and temporal scales. Thus, species must either adapt to these changes or experience negative impacts at the […]

Do pelagic grazers benefit from sea ice? Insights from the Antarctic sea ice proxy IPSO 25
Read more of: Do pelagic grazers benefit from sea ice? Insights from the Antarctic sea ice proxy IPSO 25Sea ice affects primary production in polar regions in multiple ways. It can dampen water column productivity by reducing light or nutrient supply, provide a habitat for ice algae and […]

Global phenological insensitivity to shifting ocean temperatures among seabirds
Read more of: Global phenological insensitivity to shifting ocean temperatures among seabirdsReproductive timing in many taxa plays a key role in determining breeding productivity and is often sensitive to climatic conditions. Current climate change may alter the timing of breeding at […]
