Predicting surface abundance of federally threatened Jollyville Plateau Salamanders (Eurycea tonkawae) to inform management activities at a highly modified urban spring [PDF]

open access: yesPeerJ, 2022
Urban expansion has contributed to the loss of habitat for range restricted species across the globe. Managing wildlife populations within these urban settings presents the challenge of balancing human and wildlife needs.

Corrigenda: New occurrence records for stygobiontic invertebrates from the Edwards and Trinity aquifers in west-central Texas, USA. Subterranean Biology 28: 1–13. https://doi.org/10.3897/subtbiol.28.29282 [PDF]

open access: yesSubterranean Biology, 2019
It has come to our attention that in Table 2, four records of Cirolanides sp. were mistakenly labeled as having been catalogued in the University of Texas Insect Collections (UTIC), when in fact they are catalogued in the Aquifer Biology Collection at ...

Subterranean movement inferred by temporary emigration in Barton Springs salamanders (Eurycea sosorum) [PDF]

open access: yesPeerJ, 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.

Karst Groundwater Vulnerability Determined by Modeled Age and Residence Time Tracers

open access: yesGeophysical 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.

Toward Reproducible Environmental Modeling for Decision Support: A Worked Example

open access: yesFrontiers 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 ...

Chemolithoautotrophic contributions to stygofaunal food webs in the Barton Springs Segment of the Edwards Aquifer, Texas [PDF]

open access: yesSubterranean Biology
Karst groundwater ecosystems can rely on organic matter (OM) sourced from the surface, but dependance on this can be unreliable depending on how surface water recharges the subsurface.

Tracer testing in the Edwards Aquifer [PDF]

open access: yes, 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.
