New and revised groundwater snails (Mollusca, Caenogastropoda, Cochliopidae) from karst and associated hyporheic habitats in western Texas and northern Mexico [PDF]

open access: yesSubterranean Biology
The freshwater gastropod family Cochliopidae is a diverse component of the subterranean fauna in the karst and hyporheic habitats of western Texas and northern Mexico, with 11 genera and 27 described species found in the region.

Prediction, time variance, and classification of hydraulic response to recharge in two karst aquifers [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Many karst aquifers are rapidly filled and depleted and therefore are likely to be susceptible to changes in short-term climate variability. Here we explore methods that could be applied to model site-specific hydraulic responses, with the intent of ...

Comparison of Real Versus Synthetic NOM on Lead and Copper Release Using Dump and Fill Studies

open access: yesAWWA Water Science, Volume 7, Issue 5, September/October 2025.
ABSTRACT The main objective of this study was to evaluate and compare the impact of real and synthetic NOM on lead and copper release from galvanic corrosion. A 21‐week “dump and fill” experiment was completed using test pieces with new lead and copper pipes exposed to various drinking waters.

Environmental controls on organic matter production and transport across surface-subsurface and geochemical boundaries in the Edwards aquifer, Texas, USA

open access: yesActa Carsologica, 2013
Karst aquifer phreatic zones are energy limited habitats supported by organic matter (OM) flow across physical and geochemical boundaries. Photosynthetic OM enters the Edwards Aquifer of Central Texas via streams sinking along its northeastern border ...

Topical application of hormone gonadotropin‐releasing hormone (GnRH‐A) stimulates reproduction in the endangered Texas blind salamander (Eurycea rathbuni)

open access: yesConservation Science and Practice, 2022
We present a landmark success of a pilot study in the noninvasive, topical hormonal stimulation of reproduction of salamanders using Texas blind salamanders (Eurycea rathbuni) as a model species.

Do environmental fluctuations during development affect trait variation? An experimental test with salinity

open access: yesOikos, Volume 2025, Issue 9, September 2025.
Human‐induced climate change is a driver of extinction, with extreme events occurring more frequently. It increases both the amount and fluctuations in environmental stress that organisms experience. In such environments, greater intra‐specific trait variation creates more potential for adaptation through natural selection.

Recent Advances in Tracer‐Aided Mixing Modeling of Water in the Critical Zone

open access: yesReviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Safeguarding water resources for society and ecosystems requires a comprehensive understanding of hydrological fluxes within the Critical Zone, Earth's living skin where the atmosphere, hydrosphere, biosphere, and lithosphere meet. For decades, tracer‐aided mixing models have been used to track water flow paths through the Critical Zone ...

Geomechanics of Flooding‐Induced Microseismicity—Implications for Post‐Mining Environments

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Seismicity related to mining has gained considerable public attention in the last decades and is one of the reasons for mine closures in Germany. The seismicity in the Ruhr coal mining district of Germany has been monitored by different regional and (temporal) local networks and is classified as purely mining‐induced without evidence for ...
