Research on the thermal biology of A ntarctic marine organisms has increased awareness of their vulnerability to climate change, as a flipside of their adaptation to life in the permanent cold and their limited capacity to acclimate to variable temperatures. Here, we employed a species‐specific microarray of the A ntarctic eelpout, P achycara brachycephalum , to identify long‐term shifts in gene expression after 2 months of ac...

This study investigated the impact of lipid extraction, CaCO 3 removal and of both treatments combined on fish tissue δ 13 C, δ 15 N and C:N ratio. Furthermore, the suitability of empirical δ 13 C lipid normalization and correction models was examined. δ 15 N was affected by lipid extraction (increase of up to 1·65‰) and by the combination of both treatments, while acidification alone showed no effect. The observed shift in δ...
