Climate-driven shifts in algal-bacterial interaction of high-mountain lakes in two years spanning a decade

Abstract Algal-bacterial interactions include mutualism, commensalism, and predation. However, how multiple environmental conditions that regulate the strength and prevalence of a given interaction remains unclear. Here, we test the hypothesis that the prevailing algal-bacterial interaction shifted...
