UTLs were used to determine whether whole animal acclimation had occurred in R. perrieri on heated settlement panels in the Antarctic. The panels were placed at 15m depth at two sites (South Cove and North Cove) near Rothera Research Station, Adelaide Island, Antarctic Peninsula (67.06861 S, 68.125 W). Heated and non-heated panels (one each of control, +1, +2) from the South Cove and North Cove sites colonised by R. perrieri were transferred to a 60 L jacketed tank with aerated sea water at the same temperature as the ambient sea water (0 degrees Celsius) and connected to a thermocirculator (Grant Instruments Ltd, Cambridge, UK). The temperature was raised at 1 degree Celsius h-1 with the temperature limit of each animal noted when they no longer responded to tactile stimuli.# Funding was provided by the NERC grant NE/J007501/1. : UTL data were non-normal, even after transformations, so non-parametric statistical tests were used to analyse the data. A Mann-Whitney test verified that both the South Cove and North Cove data could be combined (p = 0.0896). A Kruskal-Wallis test was used to investigate if there was an effect of temperature on UTL compared with panel treatment and Mann-Whitney tests were subsequently used on these data to identify significance between panel treatments. : The EMBRIC Configurator service was used to guide generation of transcriptomic and 16S rRNA amplicon sequencing data (study PRJEB27537 and PRJEB30562, respectively) that are associated with this dataset.
