Observed Hydroclimatic Trends and Their Implications Over Water-Cycle Dynamics in Montérégie, Southern Quebec, Canada. [PDF]

open access: yesGlob Chall
In this study, we quantified the changes in different hydroclimatic parameters and evaluated their impacts on the groundwater resources across Montérégie. Using the GR4J+CemaNeige model, and multi‐decadal hydroclimatic records, the study shows the watershed's variability and identifies seasons and land cover scenarios where groundwater recharge ...

Higher Trophic Status Leads to More Diverse and Divergent Microeukaryote Communities Over Time in Urban Lakes From the Greater Paris (France). [PDF]

open access: yesEnviron Microbiol Rep
Microeukaryote dynamics across a eutrophication gradient in Greater Paris region lakes showed richness peaking at intermediate trophic levels and communities becoming more modular, variable, and less connected with higher trophic status compared to oligo‐to‐mesotrophic lakes.
