Anaerobic Codigestion of Municipal Wastewater, Landfill Leachate, and Crude Glycerin: Process Stability and Methane Yield Assessment Using a Screening Design

open access: yesWater Environment Research, Volume 98, Issue 2, February 2026.
Anaerobic codigestion of municipal wastewater with landfill leachate and crude glycerin can achieve near‐theoretical methane yields (0.349 L NCH4/g tCODadd). An optimal mixture of 2% leachate and 1% glycerin was identified, as higher glycerin content negatively impacted performance, highlighting the criticality of substrate balance for energy recovery.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Functional Guilds Mediate the Effects of Woody Encroachment on the Ground Layer in the Brazilian Cerrado

open access: yesJournal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
After 60 years without fire, as tree biomass increases, the Cerrado vegetation is still losing biodiversity. Exploring what happens at the ground layer, we found a strong functional bias in the battle among species to survive in the shade. There are clear losers and winners, the last driving the plant community to a forest structure, composition, and ...
