Presidential Extra‐Territorialization: How Presidents Go Abroad to Bypass Domestic Constraint

Presidential Studies Quarterly, Volume 56, Issue 1, March 2026.
ABSTRACT This paper introduces the concept of presidential extra‐territorialization—the process whereby presidents act through or within a foreign jurisdiction in order to achieve a policy goal which implicates the rights commonly held by US citizens or residents.

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Groundwater Age and Nonpoint Source Pollutant Mixing in Alluvial Aquifer Wells: Comparing the Role of Diffusion, Dispersion, Aquifer Heterogeneity, and Well Screen Length

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Understanding the mixing of groundwater age and of nonpoint source (NPS) pollutants in water samples is crucial for interpreting age tracer and NPS pollutant data from production wells. Traditionally, diffusion and mechanical dispersion have been key mixing processes embedded in physical models for simulating and interpreting age tracer and ...

A Robust and Efficient Continuous‐Differentiable Seepage Face Boundary Condition for Dynamic Groundwater Modeling

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Seepage boundary conditions are commonly used in groundwater simulations to allow groundwater to discharge at the upper surface of the model when groundwater head exceeds atmospheric pressure. However, the extent and transient behavior of the seepage zone are often unknown a priori and difficult to predict.

Three‐Dimensional Geostatistical Inverse Analyses of Transient Head and Temperature Data From a Long‐Term Heat Tracer Test

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Improving the accuracy of subsurface heterogeneity characterization remains a key component in better understanding groundwater flow and contaminant transport. Heat tracer tests can provide temperature measurements, in addition to head data, that can be used for mapping heterogeneity.

Diagnosing the Flocculation–Transport Dynamics of Suspended Particulate Matter Using a Two‐Class Population Balance Model and Bayesian Calibration

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract The dynamics of suspended particulate matter (SPM) plays a crucial role in determining water quality, sediment transport, and biogeochemical cycles in inland, estuarine, and coastal water resources. Flocculation processes strongly influence the SPM dynamics via aggregation and breakage under various hydrodynamic and biogeochemical conditions ...

Non‐Invasive Imaging of Solute Redistribution Below Evaporating Surfaces Using 23Na‐MRI

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Saline water evaporation from porous media is a key phenomenon in the terrestrial environment and is linked to problems such as soil salinization and weathering of building materials. Recent modeling studies suggest the development of local instabilities due to density differences during evaporation in case of saturated porous media with high ...
