Diversity of sulfur cycling halophiles within the Salton Sea, California's largest lake.

ABSTRACT:

Background

Microorganisms are the biotic foundation for nutrient cycling across ecosystems, and their assembly is often based on the nutrient availability of their environment. Though previous research has explored the seasonal lake turnover and geochemical cycling within the Salton Sea, California's largest lake, the microbial community of this declining ecosystem has been largely overlooked. We collected seawater from a single location within the Salton Sea at 0 m, 3 m, 4 m, 5 m, 7 m, 9 m, 10 m, and 10.5 m depths in August 2021, December 2021, and April 2022.

Results

We observed that the water column microbiome significantly varied by season (R² = 0.59, P = 0.003). Temperature (R² = 0.27, P = 0.004), dissolved organic matter (R² = 0.13, P =
