Host performance associated OTUs
In total, 382 OTUs were differentially abundant between temperature
regimes, 206 of which specific to 15 °C and 176 to 22 °C (Figure S2A).
Between ranges, we detected 578 differentially abundant OTUs, including
205 OTUs more abundant in native and 373 OTUs more abundant in
non-native populations (Figure S2B). Further, we found 29 OTUs to
correlate positively and 9 OTUs to correlate negatively with RGR (Figure
S2C) and 2 OTUs to correlate positively and 9 OTUs to correlate
negatively with the thallus brittleness (Figure S2D).
