Grey Hill Zircon – A Natural High 176Yb/177Hf Zircon Reference Material for LA‐MC‐ICP‐MS Hf Isotope Measurement

Geostandards and Geoanalytical Research, EarlyView.
Key Points New natural high REE/Hf zircon reference material for in situ Hf isotopic measurement. Hf isotope ratio is independent of zircon textural domains. Stable Hf isotope ratio despite Pb and REE variability. Accurate measurements of Hf isotope ratios in zircon rely on adequate correction for isobaric interferences, which increase in complexity as

A Categorical Machine Learning Approach to Predicting Areas of Shallow Coastal Groundwater

Groundwater, EarlyView.
Abstract Coastal lowlands are increasingly vulnerable to threats from sea‐level and associated groundwater rise. This study introduces a categorical modeling framework that redefines groundwater depth estimation as a classification problem rather than a continuous prediction task. By dividing groundwater occurrence into multiple depth thresholds (0.9–2.

Aquitardifer: A New Hydrogeologic Term for Geologic Materials with both Aquitard and Aquifer Properties

Groundwater, EarlyView.
Abstract We propose that a new term, aquitardifer, be added to the hydrogeologic nomenclature. Aquitardifer, a blend of the terms aquitard and aquifer, accounts for geologic materials that have properties of both as traditionally defined. Several examples of aquitardifers are provided, as is justification for and applicability of the term.

The Dry‐Climate Hypothesis: Identifying the Environmental Drivers of Terrestrial Viviparous Salamanders

Journal of Biogeography, EarlyView.
ABSTRACT Aim The evolution of adaptive innovations carries strong eco‐evolutionary implications, allowing organisms to explore novel ecological opportunities, which facilitates lineage diversification. The remarkable diversity of reproductive strategies in amphibians provides a natural laboratory for identifying ecological mechanisms driving ...
