a, b Growth rates (measured as change in turbidity [OD600] per hour) of bacteria from HTV, ITV and LTV sediments sampled in August and December, respectively, measured at 10 °C, 20 °C, 30 °C, 40 °C, and 50 °C. Star (*) indicates statistical differences in the growth of the enriched heterotrophic bacterial fraction obtained from different temperature variabilities across the tested temperatures; ANOVA, a August 40 °C: F2,6 = 169.3, p < 0.0001 and 50 °C: F2,6 = 11.04, p = 0.0098, b December 40 °C: F2,6 = 23.06, p = 0.0015. c Taxonomic diversity, at the genus level, of the enriched heterotrophic bacteria present at the end of incubation at different temperatures (20 °C, 30 °C, and 40 °C) in August and December; values are expressed as the relative abundance of each genus measured at the end of the incubation (when samples were collected). d Relative abundance of OTUs shared across the enriched heterotrophic bacterial community fraction from HTV, ITV and LTV, grown at 20 °C, 30 °C, and 40 °C; values are expressed as percentages.
