Changes in temperature alter the potential outcomes of virus host shifts 2018-10-19 .txt text/plain 7102 382 51 Susceptibility to infection is known to vary with temperature, due to within individual physiological changes in factors such as the host immune response, metabolic rate or behavioural adaptations [22] [23] [24] [25] . However, if the host phylogeny also explains much of the variation in thermal tolerance, then phylogenetic patterns in virus susceptibility could be due to differences between species' natural thermal optima and the chosen assay temperatures. We infected 45 species of Drosophilidae with Drosophila C Virus (DCV; Dicistroviridae) at three different temperatures and measured how viral load changes with temperature. We also examine how proxies for thermal optima and cellular function (thermal tolerances and basal metabolic rate) relate to virus susceptibility across temperatures, as increasing temperatures may have broad effects on both host and parasite [43] [44] [45] . To investigate the effect of temperature on virus host shifts we quantified viral load in 12,827 flies over 396 biological replicates, from 45 species of Drosophilidae at three temperatures ( Fig 1) . ./cache/cord-290253-hxxizipk.txt ./txt/cord-290253-hxxizipk.txt
