Functional traits explain growth response to successive hotter droughts across a wide set of common and future tree species in Europe

Plant Biology, EarlyView.
Functional traits can explain significant tree growth reductions in response to the 2018–2020 drought for a wide set of 71 species including angiosperms and gymnosperms. Moreover, four distinct response types emerged: ‘Sufferer’, ‘Late sufferer’, ‘Recoverer’ and ‘Resister’, with gymnosperms predominately appearing as ‘Sufferer’ and ‘Late sufferer ...

Soil health as nonequilibrium flow: Bridging a persistent conceptual‐to‐computational inconsistency

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Soil health concepts emphasize soil aggregation and structure as central indicators of healthy, functioning soils, yet this emphasis carries an implicit acknowledgment rarely made explicit in models: aggregated soils exhibit nonequilibrium water flow behaviors through preferential pathways.

Soil hydraulic properties of a Nitisol in Kabete, Kenya [PDF]

, 2012
Water relations are among the most important physical phenomena that affect the use of soils for agricultural, ecological, environmental, and engineering purposes. To formulate soil-water relationships, soil hydraulic properties are required as essential

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Investigation of Semi-Empirical Model of Unsaturated Hydraulic Conductivity Based on Some Measurable Physical Soil Properties, Case Study: Baghin Plain, Kerman [PDF]

مهندسی منابع آب, 2013
Unsaturated hydraulic conductivity is one of the basic properties of soil that governs the water movement in the field. As application of any of the various available methods in the field deemed impracticable due to its difficulty of implication and high

Migration of Per‐ and Polyfluoroalkyl Substances in Soil Under Rainfall Simulation

CLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
A rainfall simulation is conducted to evaluate the migration of PFAS in soil spiked with aqueous‐film‐forming foam during rainfall. Most PFAS migrate via leaching, followed by runoff. High PFAS concentration in soil (⩾30 mg/kg) could alter soil hydraulic conductivity and inhibits leaching.

Predicting the Unsaturated Hydraulic Conductivity of Compacted Polyurethane–Clay Using the Filter Paper Method

Applied Sciences
Sanitary landfill covers are exposed to varying environmental conditions; hence, the state of the clay layer also changes from saturated to unsaturated. The study aimed to predict the unsaturated hydraulic conductivity of the locally available compacted ...
