Repetition and order of exposure to salinization and nutrient enrichment drive freshwater microbial community responses.

ABSTRACT: Biological systems face multiple stressors that impact biodiversity and ecosystem functions, with complex interactions that vary spatially and temporally leading to unpredictable outcomes. In freshwater ecosystems, benthic microbial communities underpin vital functions like decomposition and primary productivity, but are threatened by stressors such as salinization and nutrient enrichment, which are intensifying and increasingly co-occurring due to climate change. We experimentally tested how stressor repetition and different orders of stressor exposure affect freshwater benthic microbial community responses over time. Communities established on tiles in 1000 L open freshwater ponds established more than 10 years ago in the field were exposed to elevated salinity and nutrient enrichment, e
