| contents | Effects of Extreme Rainfall on a Dominant Seaweed Are Mitigated by Its Microbiota. McGrath, Alexander H Steinberg, Peter D Kjelleberg, Staffan Marzinelli, Ezequiel M Extreme weather events are becoming more intense and frequent, driving unprecedented ecological changes globally. The effects of such extreme events can be particularly profound if they affect the performance of habitat-forming organisms (trees, corals, kelp). Further, the emergence of the "holobiont" concept in biology suggests that these impacts can occur directly on the habitat-forming "host" and/or via disruption of their associated microbiota. Following a one-in-100 year rainfall event along the coast of Sydney, Australia, we examined the effects of rainfall (in the field) and lowered salinity (in the lab) on the performance and reproductive output of a dominant, habitat-forming intertidal seaweed, . We then examined the ability of surface-associated microbes to mitigate host responses to extreme rainfall via microbial manipulations in the field. Extreme rainfall and reduced salinity ( |
