From temperate to polar waters: Transition to non‐cyanobacterial diazotrophy upon entering the Atlantic gateway of the Arctic Ocean

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrogen fixation, the microbial reduction of dinitrogen to ammonia, is increasingly recognized to occur in the Arctic Ocean. However, knowledge about the composition, biogeography, abundance, and ecology of nitrogen‐fixing organisms (diazotrophs) is poor.

Mixing regimes in tropical high‐mountain Andean lakes

open access: yesLimnology and Oceanography, EarlyView.
Abstract Lowland tropical lakes deeper than 15 m are typically warm monomictic, but whether the regime may switch to polymixis at high elevations remains uncertain. Using a year‐long high‐frequency dataset from thermistor chains from 10 deep lakes and occasional temperature profiles from 202 lakes in Ecuador's Cajas Massif, this study examines the ...

Broad‐scale climate patterns combined with local flow and turbidity disturbances structure the seasonality of gross primary production in an aridland river

open access: yesLimnology and Oceanography, EarlyView.
Abstract Both local and global climate phenomena shape the hydrologic regimes of watersheds. For aridland rivers in the southwestern United States, peak flows occur during two distinct periods: spring snowmelt and summer monsoons. Although discharge (Q) is a primary driver of variation in the production and consumption of instream organic matter, or ...

Under which conditions can tidal reeds contribute to shore protection? The critical interplay between external stress and internal stress resistance in brackish marshes

open access: yesLimnology and Oceanography, EarlyView.
Abstract Tidal reeds provide essential coastal protection by shielding the shore from the effects of waves and currents, reducing soil erosion or even enabling sediment accretion. However, these environments face increasing threats from human activities and climate change.
