Are flood-driven turbidity currents hot spots for priming effect in lakes? [PDF]
Biogeosciences, 2016 In deep stratified lakes, such as Lake Geneva, flood-driven turbidity currents are thought to contribute to the replenishment of deep oxygen by significant transport of river waters saturated with oxygen into the hypolimnion.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Water Resources Research, Volume 62, Issue 4, April 2026.Abstract Autumn is a pivotal but understudied season in limnology. As climate change alters the timing and duration of autumnal cooling, the implications for winter thermal structure and long‐term ecosystem function in dimictic lakes remain uncertain.

Ecology of Freshwater Fish, Volume 35, Issue 2, April 2026.ABSTRACT Seasonal changes in freshwater ecosystems influence fish resource use through both environmental and biological factors, but year‐round studies that include ice‐covered months have been lacking. We investigated seasonal variation in the stable isotope ratios of carbon (δ13C) and nitrogen (δ15N) using year‐round monthly sampling of the fish ...

A global estimator of C and N isotope baselines for fresh waters
Methods in Ecology and Evolution, Volume 17, Issue 3, Page 992-1006, March 2026.Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Limnology and Oceanography, Volume 71, Issue 2, Page 1-14, February 2026.Abstract Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope measurements (carbon and nitrogen) of brown trout (Salmo trutta, n = 2854) and Arctic charr (Salvelinus alpinus, n = 3062) from 120 cold‐water ...
