Landscape Connectivity and Wildlife Access to Water Across an International Border: Barriers and Opportunities for Facilitating Transboundary Movement

open access: yesGlobal Change Biology, Volume 32, Issue 5, May 2026.
The construction of barriers along international borders is increasing globally, including along the boundary between the United States and Mexico. We used a landscape connectivity model to investigate the effects of barriers on wildlife access to water within the Lower Rio Grande Valley (Texas, USA) across three scenarios: (1) without border barriers;

The Reactivity of Bispidine Ligand Based Iron(IV) and Iron(V) Oxido Species for the Demethylation of Acetic Acid

open access: yesJournal of Computational Chemistry, Volume 47, Issue 11, 30 April 2026.
In agreement with experiment, DFT shows that high‐valent iron bispidines readily react with acetic acid by HAA (hydrogen atom abstraction) to produce C1 products in various oxidation states. ABSTRACT The high valent bispidine iron‐oxido complexes LFeIV═O and LFeV═O show exceptionally high reactivity for C–H abstraction reactions.

Improved Simulation of Seasonal Variation of Arctic Low Clouds by Resolving Subgrid Open Water Fluxes to the Atmosphere in CESM2

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Open water in sea ice significantly influences Arctic low‐cloud formation. However, current global climate models (GCMs), constrained by grid‐scale coupling between the atmosphere and surface components, cannot resolve subgrid heat fluxes and clouds contrasts between open water and sea ice, contributing to biases in Arctic low‐cloud ...

Inorganic Nitrate Enhances Cloud Activation of Less Hygroscopic Aerosols at a Coastal Site in California

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Anthropogenic aerosols influence marine cloud properties in coastal regions, but their impacts remain poorly understood due to the complexity of sources and aerosol‐cloud interactions. To investigate how cloud processing affects aerosol composition, in situ measurements of aerosol properties were performed at Mt. Soledad in La Jolla, CA (251 m
