Ecogenomics and limnological dynamics of a new Thiocapsa species blooming in the whole water column of a karstic lake

open access: yesLimnology and Oceanography, EarlyView.
Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Contrasting functional responses of benthic and hyporheic stream biofilms to light availability and macronutrient stoichiometry

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.

Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

open access: yesLimnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Pteropods as early‐warning indicators of ocean acidification

open access: yesLimnology and Oceanography, EarlyView.
Abstract Aragonite undersaturation (Ωar$$ {\Omega}_{\mathrm{ar}} $$ <$$ < $$ 1) events are projected to rapidly increase in frequency and duration in the Antarctic Weddell Sea by 2050. Thecosome pteropods (pelagic snails) are bioindicators of ocean acidification (OA) because their aragonite shell dissolves easily at low Ωar$$ {\Omega}_{\mathrm{ar ...
