Geospatial and AHP based identification of potential zones for groundwater recharge in Haridwar District of India

open access: yesFrontiers in Environmental Science
Demarcation of the groundwater recharge prospective zones can be the foremost step in facilitating groundwater recharge in any terrain, as most nations have a major concern about unreasonable use of groundwater and declining the water table.

Notes From the Era of Pre‐Modern Fishing in the Baltic Sea Reveal an Extensive and Resilient Fishing Mode

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT In the past half‐century, fishing in one regional part of the Baltic Sea, the Stockholm Archipelago, has almost disappeared due to falling fish abundance, especially of herring (Clupea harengus). By examining published observations and archived material on historical fishing patterns, we found evidence of a remarkably continuous high level of ...

Polygonal tepee structures of Arabia

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

INTEGRAÇÃO ENTRE DADOS ÓPTICOS E RADAR (SRTM) PARA A CARACTERIZAÇÃO GEOAMBIENTAL DA COSTA SETENTRIONAL DO RIO GRANDE DO NORTE / RADAR (SRTM) AND OPTICAL DATA COMBINATION FOR GEOENVIRONMENTAL CHARACTERIZATION OF THE RIO GRANDE DO NORTE NOTHERN COAST

open access: yesRevista Geográfica Acadêmica, 2008
The demand for energetic resources on the country increased the exploration of hydrocarbon andconsequently the risk of oil spill on environmentally sensible areas located on the Rio Grande do Nortenorthern coast.

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

Ephemeropteran and Trichopteran Assemblages Vary Across a Subtropical Rainforest Altitudinal Gradient: Useful Indicators for Climate Change

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This figure provides the elevation distribution of Trichoptera and Ephemeroptera across the elevational gradient and clearly shows how specific morphospecies can be used as indicators. ABSTRACT The subtropical rainforests of eastern Australia are expected to be greatly affected by climate change, with several studies predicting an upward shift in ...

Palaeoglacier reconstruction and dynamics of Cordillera Vilcanota in the tropical high Peruvian Andes

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

JAMES BUTTLE REVIEW: A Synthesis of Riparian Plant Water Use Over Two Decades in North American Drylands

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Using the most complete summary of 20 years of riparian plant water use studies in North American drylands to date, we examine broad patterns of plant water use by vegetation type and across climate gradients. Marshes, cottonwood‐willow stands and tamarisk use larger amounts of water than other communities, and all communities have higher water use in ...

Impacts of a Century‐Old Urban Dam on Water Quality and Habitat Composition, Flint River, Flint, MI

open access: yesRiver Research and Applications, Volume 42, Issue 2, Page 432-443, February 2026.
ABSTRACT Dams significantly influence river ecosystems worldwide, fragmenting habitats, altering sediment transport, and reducing biodiversity. Urban rivers are especially vulnerable, where dams compound stressors such as channelization, pollution, and degraded riparian zones. In response, dam removals are a growing restoration tool globally.
