Natural Source Zone Depletion of Crude Oil in the Subsurface: Processes Controlling Mass Losses of Individual Compounds

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract At many petroleum hydrocarbon spill sites, residual spilled product forms a long‐term source of groundwater contamination. The phrase source zone natural depletion is used to refer to the mass loss rates. Overall mass lost under environmental conditions was analyzed using conservative biomarker concentrations for a 1979 oil spill in northern ...

Evolutionary Isolation and Ecological Stasis in the Endangered Comal Springs Dryopid Beetle (Stygoparnus comalensis)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The Comal Springs dryopid beetle (Stygoparnus comalensis) (Coleoptera: Dryopidae) is an endangered, subterranean‐obligate, long‐toed water beetle known only from three spring complexes in the Edwards Aquifer region of Texas. Due to their small size and reliance on groundwater karst habitats, little is known of the biology of these beetles. The

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions. In total, 15,299 cryoconite holes and 1 600 structures were geospatially analyzed, which indicate that ...

Direct Numerical Simulation of Solute Transport in Bioclogged Porous Media

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Biofilms in porous media significantly impact solute transport, beyond their role in reducing permeability through bioclogging. Experimental evidence has shown that biofilms can induce anomalous transport behaviors such as increased dispersion and pronounced tailing.
