Relative abundance of atropisomer pairs in metolachlor metabolites, MESA and MOXA, vary with slope and hydric soils in subwatersheds of the Choptank River watershed, Maryland.

Metolachlor is the most heavily used member of acetanilide herbicides, which are noted for forming highly soluble metabolites in root zone soils soon after field application. The two primary metabolites of metolachlor, metolachlor ethane sulfonic acid (MESA) and metolachlor oxanilic acid (MOXA), retain the same chiral chemistry as their source and are important tracers of nitrate loading from agricultural cropland. New analytical methods for separating the isomers of MESA and MOXA, enable studies assessing changes in the abundance of atropisomer pairs of the carbon chiral enantiomers in environmental samples.

Flooding remains a critical issue in urban catchments, driven by complex interactions between land use changes, hydrological dynamics, and environmental factors. This study aims to investigate how modifications in Landscape Hydric Potential (LHP) affect flood behavior in the Drwinka River catchment in Krakow, Poland. Given the rapid urbanization and its impacts on hydrological systems, understanding these changes is essential for effective flood management and mitigation.

Maintaining stable hydric and thermal states are dual challenges for reptiles that inhabit terrestrial environments with variable conditions across time and space. Under some conditions, reptiles face a conundrum where both physiological parameters cannot be simultaneously maintained at preferred levels by behavioral or physiological means. Prioritization of behavioral regulation of hydric or thermal state, and at which point this prioritization changes, was tested for nine species of congeneric tropical geckos by assessing their use of microhabitats with distinct thermal and hydric conditions in a controlled environment.

Hydric stress is a leading cause of atypical aging (ATA) in wine, characterized by unpleasant olfactory notes. The main sensorial and chemical marker of ATA is 2-aminoacetophenone (AAP). Early detection of ATA before the second fermentation in sparkling wines (SWs) is crucial for producing high-quality products.

Mammals use burrows to behaviourally thermoregulate, save water, and avoid predation. The advantages of burrows vary not only seasonally but also with burrow depth. To quantify these effects, we used biophysical ecological models, which predict an animal's energetic and hydric costs within a characterised microclimate.
