Abstract Environmental shifts can cause epigenetic modifications in corals, which are associated with changes in gene expression and physiology, though it remains unclear if associated bacteria can also induce such changes. Here, we inoculated nubbins of the coral Pocillopora verrucosa with an opportunistic pathogen, Vibrio coralliilyticus, and/or a coral probiotic, Cobetia sp., and subjected the nubbins to heat stress.

New Results doi: https://doi.org/10.1101/2023.01.07.523113 Abstract Chlamydomonas algal blooms give snowmelt a red color, reducing snow albedo and creating a runaway effect that accelerates snow melting. The occurrence of red snow is predicted to grow in polar and subpolar regions with increasing global temperatures. Here, a global metaanalysis of microbial abundances showed that red snow had higher microbial abundances than white snow.
