Low<i>P</i><sub>crit</sub>but no hypoxia tolerance? Hypoxia compensation in the Arctic keystone species<i>Boreogadus saida</i> Open
Global warming has already caused a loss of almost 50% Arctic sea-ice coverage since the 1980s. Sea-ice loss strengthens summer stratification of the ocean’s water column and, consequently, hypoxic zones in the deep-water layers may form. …

Protein Synthesis Determined from Non-Radioactive Phenylalanine Incorporated by Antarctic Fish Open
Direct measurements of temperature-dependent weight gains are experimentally challenging and time-consuming in long-lived/slow-growing organisms such as Antarctic fish. Here, we reassess methodology to quantify the in vivo protein synthesi…
