Effects of temporal and spatial variability in energy fluxes on phytoplankton

open access: yesLimnology 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 ...

From modality to millianism

open access: yesNoûs, Volume 59, Issue 4, Page 851-872, December 2025.

New definitions are provided for various epistemic modal notions.
