Effects of temporal and spatial variability in energy fluxes on phytoplankton
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

Freshwater Biology, Volume 71, Issue 1, January 2026.ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.
