An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Nest Predation in the Canarian Houbara Bustard (Chlamydotis undulata fuertaventurae): An Experimental Study Using Artificial Nests

Ecological Research, Volume 41, Issue 3, May 2026.
We investigated nest predation in the endangered Canarian houbara bustard using 229 artificial nests and camera traps. Ravens were identified as the main predators, and predation rates were influenced by raven density, vegetation cover, stone cover, and road density.

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

Global 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

Journal 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.
