Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

Behavioral and demographic effects of open‐pit mining on Central Mountain Caribou in British Columbia

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
The demographic manifestation of mining effects on caribou, a species listed as Vulnerable on the IUCN Red List of Threatened Species, has been disputed. We characterized a cascade of events for caribou associated with open‐pit coal mining beginning with maladaptive behavior responses leading to negative demographic outcomes for the affected caribou ...

Mountain‐top spherules: Criteria to identify natural and synthetic particles

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 5, Page 898-913, May 2026.
Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1510-1521, May 2026.
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Adsorption Preceding Wetting Front Controls Seismic Velocity

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Rock elasticity varies with both humidity and water saturation, yet their combined effects remain poorly understood, although in nature vapor adsorption and liquid infiltration occur simultaneously. Here, we present experimental data of P‐wave velocity and volume expansion in a free‐standing sandstone subject to progressive wetting.
