Even though fungi are ubiquitous in the biosphere, ecological knowledge of marine remains rather rudimentary. Also, little is known about their tolerance to salinity and how it influences activities. Extracellular enzymatic activities (EEAs) widely used determine heterotrophic microbes’ capabilities substrate preferences. Five fungal species belonging most abundant pelagic phyla (Ascomycota Basidiomycota) were grown under non-saline saline conditions (0 g/L 35 g/L, respectively). Due...
The Southern Ocean is characterized by longitudinal water circulations crossed strong latitudinal gradients. How this oceanographic background shapes planktonic populations largely unknown, despite the significance of region for global biogeochemical cycles. Here, we show, based on genomic, morphometric, ecophysiological and mating compatibility data, an example ecotypic differentiation speciation within endemic pelagic inhabitant, diatom Fragilariopsis kerguelensis. We discovered three...
Although terrestrial and aquatic fungi are well-known decomposers of organic matter, the role marine remains largely unknown. Recent studies based on omics suggest that potentially play a major in elemental cycles. However, there is very limited information diversity extracellular enzymatic activities performed by pelagic ocean how these might be affected community composition and/or critical environmental parameters such as temperature. In order to obtain potential metabolic activity fungi,...
Ergosterol has traditionally been used as a proxy to estimate fungal biomass it is almost exclusively found in lipid membranes. determination mostly for samples from terrestrial, freshwater, salt marsh- and mangrove-dominated environments or describe degradation of plant matter. In the open ocean, however, expected concentrations ergosterol are orders magnitude lower than terrestrial macrophyte-dominated coastal systems. Consequently, ocean remains largely unknown. Recent evidence based on...
