Microfabric controls on the preservation and erosion of Late Pleistocene freshwater microbialites in northwestern Patagonia, Argentina

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
Microfabric distribution controls porosity, preservation and erosion in Late Pleistocene microbialites from the Maquinchao Basin (Argentina). Differential preservation of laminated and shrub fabrics shapes the present morphology of the carbonate build‐ups and influences their palaeoenvironmental interpretation.

A GIS-Based Spatiotemporal Impact Assessment of Droughts in the Hyper-Saline Urmia Lake Basin on the Hydro-Geochemical Quality of Nearby Aquifers

open access: yesRemote Sensing, 2022
Urmia Lake is a hyper-saline lake in northwestern Iran that has been drying up since 2005. The main objective of this study was to evaluate the water quality in aquifers that are the main source of fresh water for the eastern plains Urmia Lake, which has

Delineation of Flow Components in a Tropical Region With Carbonate Rocks of Southeastern Mexico

open access: yesHydrological Processes, Volume 40, Issue 9, September 2026.
Hydrochemistry and statistical methods help to delimit the flow components in carbonate rocks with marine intrusion. ABSTRACT This study analyses groundwater flow systems in a tropical karst aquifer of the Yucatán Peninsula, Mexico, where population growth and tourism are concerns due to increasing urbanisation.

Abundant production of dimethylsulfoniopropionate as a cryoprotectant by freshwater phytoplanktonic dinoflagellates in ice-covered Lake Baikal

open access: yesCommunications Biology, 2023
Phytoplanktonic dinoflagellates form colonies between vertical ice crystals during the ice-melting season in Lake Baikal, but how the plankton survive the freezing conditions is not known.

Warm‐wet transition restructures arid lake microbiomes and functional potential

open access: yesiMetaOmics, Volume 3, Issue 3, September 2026.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

Effects of model complexity on karst catchment runoff modeling for flood warning systems

open access: yesJournal of Hydrology X
Severe flood events are deemed more frequent in the near future with a changing climate. Headwater catchments, especially when karstified, exhibit a pronounced susceptibility to swift and substantial responses to precipitation events, leading to flooding.

A Method for Identifying Rainfall‐Runoff Events at Sub‐Hourly Time Scales: Applications for Nature‐Based Solutions and Water Resources

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1586-1603, September 2026.
ABSTRACT Understanding how changes in catchment conditions affect ecohydrology in response to rainfall‐runoff events is crucial when developing informed strategies to enhance flow resilience, restore natural habitats, interpret water quality data or reduce flood risk.

Monitoring of Polychlorinated Biphenyls in the Transboundary Ile River and Characteristics of Its Transformations Along the River’s Discharge

open access: yesApplied Sciences
This study presents the level of polychlorinated biphenyl (PCB) pollution in the transboundary Ile River in 2015, 2018, 2019, 2023, and 2024. PCB contamination of water, as well as the presence of a large number of individual congeners, including ...
