Distinct oxygen environments shape picoeukaryote assemblages thriving oxygen minimum zone waters off central Chile
De la Iglesia, Rodrigo; Echeñique-Subiabre, Isidora [Univ Mayor, Gema Ctr Genom Ecol & Environm, Fac Sci, Chile]; Rodríguez-Marconi, Susana [Univ Mayor, Gema Ctr Genom Ecol & Environm, Fac Sci, Chile]; Pablo Espinoza, Juan; von Dassow, Peter; Ulloa, Osvaldo; Trefault, Nicole [Univ Mayor, Gema Ctr Genom Ecol & Environm, Fac Sci, Chile] (Oxford University Press, 2020-09)Oxygen minimum zones (OMZs) support ocean biogeochemical cycles of global importance. The OMZ off central Chile is characterized by seasonally variable oxygen concentrations due to upwelling events. Bacterial and archaeal ... -
Distinctive Archaeal Composition of an Artisanal Crystallizer Pond and Functional Insights Into Salt-Saturated Hypersaline Environment Adaptation
Trefault, Nicole [Univ Mayor, GEMA Ctr Genom Ecol & Environm, Santiago, Chile]; Plominsky, Alvaro M.; Henriquez-Castillo, Carlos; Delherbe, Nathalie; Podell, Sheila; Ramírez-Flandes, Salvador; Ugalde, Juan A.; Santibañez, Juan F.; van den Engh, Ger; Hanselmann, Kurt; Ulloa, Osvaldo; De la Iglesia, Rodrigo; Allen, Eric E. (FRONTIERS MEDIA SA, 2018)Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad ... -
Metabolic potential and in situ transcriptomic profiles of previously uncharacterized key microbial groups involved in coupled carbon, nitrogen and sulfur cycling in anoxic marine zones
Trefault, Nicole [Univ Mayor, GEMA Ctr Genom Ecol & Environm, Santiago, Chile]; Plominsky, Alvaro M.; Podell, Sheila; Blanton, Jessica M.; De la Iglesia, Rodrigo; Allen, Eric E.; von Dassow, Peter; Ulloa, Osvaldo (WILEY, 2018)Anoxic marine zones (AMZs) impact biogeochemical cycles at the global scale, particularly the nitrogen cycle. Key microbial players from AMZs have been identified, but the majority remains unrecognized or uncharacterized. ...
