Temperature‐dependent growth and activity in a globally distributed nitrogen‐fixing haptophyte

open access: yesLimnology and Oceanography, EarlyView.
Abstract Dinitrogen (N2)‐fixing microorganisms play a crucial role in supplying nitrogen (N) to the oceans by converting atmospheric N2 into bioavailable N. N2 fixation was thought to be limited to warm oligotrophic ocean waters, but the association between the N2‐fixing UCYN‐A cyanobacterium and specific haptophytes, including Braarudosphaera ...

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

Trophic strategies of freshwater nanoflagellates under variable run‐off scenarios

open access: yesLimnology and Oceanography, EarlyView.
Abstract Terrestrial run‐off is increasing in temperate lakes due to climate change and can lead to loading of colored dissolved organic matter (cDOM) and nutrients, thus reducing light availability and increasing carbon, nitrogen, and phosphorus. Run‐off events are highly irregular, resulting in temporal resource variability that may determine the ...

Radiocarbon analysis reveals decomposition of old soil organic carbon into dissolved inorganic carbon in a subtropical mangrove ecosystem

open access: yesLimnology and Oceanography, EarlyView.
Abstract The outwelling of remineralized dissolved inorganic carbon (DIC) from the subsurface soil layer through tidal pumping has recently been noted for its importance in the blue carbon budget of mangroves. However, the age of soil organic carbon (SOC) that has been decomposed into DIC remains uncertain.

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
