Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Utilizing NASA's Operation IceBridge Airborne SWE and Precipitation Products to Assess Surface Snow Over Alaskan Glaciers

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

From Resistivity to Hydraulic Properties: Calibrating a Groundwater Flow Model by Integrating Airborne Electromagnetic and Borehole Data Into a Probabilistic Multi‐Texture Framework

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Airborne electromagnetic (AEM) surveys offer rapid, cost‐effective subsurface imaging, yet converting their electrical resistivity (ER) models into physically meaningful hydraulic property fields for groundwater models remains a challenge. We develop and demonstrate a data‐driven workflow for an unconsolidated sedimentary aquifer system in ...

Comparison of Remotely‐Sensed Orbital and Rover‐Based In Situ Surface Orientation Analyses in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Satellite data have been used to estimate the three‐dimensional orientation of features on Mars inferred to be bedding planes to support interpretations of deposit characteristics and depositional environments. Opportunities to ground‐truth these estimates and to understand the geologic information recorded by surfaces measured from orbit are ...

Democratizing Hydroclimate Science for Just and Resilient Futures

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Hydroclimatic extremes are intensifying, escalating risks to ecosystems, infrastructure, and vulnerable communities. Rapid technological innovation and scientific discovery offer powerful tools to address these challenges, yet a gap remains between hydroclimate knowledge production and its use in decision‐making.
