Rayleigh wave and well head response to calculate porosity in the Edwards aquifer of south-central Texas, USA [PDF]
Acta Carsologica, 2020 We use the magnitude and centroid period of Rayleigh wave along with the amplitude of fluctuations of water level in a well to calculate effective porosity of a karst aquifer at the site scale.

Subterranean environments contribute to three‐quarters of classified ecosystem services [PDF]
Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Extensive Admixture Among Karst‐Obligate Salamanders Reveals Evidence of Recent Divergence and Gene Exchange Through Aquifers [PDF]
Ecology and EvolutionKarst ecosystems often contain extraordinary biodiversity, but the complex underground aquifers of karst regions present challenges for assessing and conserving stygobiont diversity and investigating their evolutionary history.

The Chalk Streams of Southern England and Northern France Harbour Substantial Unique Components of the Overall Genetic Diversity of Atlantic Salmon (Salmo salar L.) [PDF]
Evolutionary Applications, Volume 19, Issue 4, April 2026.ABSTRACT Populations of Atlantic salmon continue to suffer marked declines in abundance due to stressors acting in both their freshwater and marine habitats. It is therefore an imperative to identify populations in need of increased conservation intervention, with the aim of preserving as much as possible the genetic diversity present within the ...

Subterranean movement inferred by temporary emigration in Barton Springs salamanders (Eurycea sosorum) [PDF]
PeerJ, 2021 Movement behavior is an important aspect of animal ecology but is challenging to study in species that are unobservable for some portion of their lives, such as those inhabiting subterranean environments.

Toward Reproducible Environmental Modeling for Decision Support: A Worked Example
Frontiers in Earth Science, 2020 A fully worked example of decision-support-scale uncertainty quantification (UQ) and parameter estimation (PE) is presented. The analyses are implemented for an existing groundwater flow model of the Edwards aquifer, Texas, USA, and are completed in a ...

Karst Groundwater Vulnerability Determined by Modeled Age and Residence Time Tracers
Geophysical Research Letters, 2023 Karst aquifers are a vital groundwater resource globally, but features such as rapid recharge and conduit flow make them highly vulnerable to land‐surface contamination.

Tracer testing in the Edwards Aquifer [PDF]
, 2019 ABSTRACT Tracer testing is established as one of the best techniques for determining groundwater velocities and identifying groundwater flow directions in karstic systems. It has been employed in the Edwards (Balcones Fault Zone) Aquifer since the mid-1980s.
