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

Limnology 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

Increasing acidification does not affect sexual reproduction of a solitary zooxanthellate coral transplanted at a carbon dioxide vent

Limnology and Oceanography, EarlyView.
Abstract The absorption of atmospheric carbon dioxide is causing significant changes to the carbonate chemistry of the ocean, in a phenomenon called ocean acidification. The latter makes it potentially more difficult for marine calcifiers like corals, to build their calcium carbonate structures, thus affecting their ability to survive and reproduce ...

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

Limnology 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

Limnology 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 ...

Phytoplankton community dynamics and vertical nutrient fluxes during the winter‐to‐spring transition in a monomictic temperate reservoir

Limnology and Oceanography, EarlyView.
Abstract Winter phytoplankton blooms have been documented in several temperate lakes, yet the mechanisms triggering them remain poorly understood. Understanding the ecology of these blooms is key for predicting succession patterns, especially given the impact of climate change on winter conditions.
