Nutrient pulse scenarios drive contrasting patterns in the functional stability of freshwater phytoplankton

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S99-S112, December 2025.
Abstract Climate change is increasing the frequency, intensity, and stochasticity of extreme weather events such as heavy rainfall, storm‐induced mixing, or prolonged drought periods. This results in more variable regimes of dissolved nutrients and carbon in lakes and induces temporal fluctuations in the resource availability for plankton communities ...
