Heat and Tectonics of the Canadian Cordillera From the Seismically Constrained Inversion of Gravity Data

Tectonics, Volume 45, Issue 2, February 2026.
Abstract An updated approach to seismically constrained modeling of gravity data reveals two broad, NW‐trending low‐density zones in the mantle lithosphere beneath the Canadian Cordillera. The low‐density zones coincide with a shallow lithosphere‐asthenosphere boundary (LAB), a shallow Curie‐point depth, and the location of Quaternary volcanoes.

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

Sedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Estimating Soil Electrical Parameters in the Canadian High Arctic From Impedance Measurements of the MIST Antenna Above the Surface

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The MIST experiment aims to detect the cosmological 21‐cm signal through sky observations at 25–125 MHz using a wide‐beam antenna. The antenna is mounted above the soil and the beam characteristics are highly dependent on the soil's electrical properties.

Decadal‐Scale In Situ Scanning of a Stalagmite From Southwest China Reveals Blake Geomagnetic Excursion Structure

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present a decadal‐scale paleomagnetic analysis of a stalagmite collected from Shuixi Cave, southwest China, spanning 89−123 ka. Our findings include: (a) Magnetite is the dominant magnetic mineral, and paleomagnetic directions can be obtained via demagnetization; (b) Magnetic scanning at 0.1‐mm resolution captures key magnetic features ...

The state and fate of Glaciar Perito Moreno Patagonia

Communications Earth & Environment
Glaciar Perito Moreno, located in the Southern Patagonian Icefields, has long been considered stable despite widespread regional glacier retreat. Unlike neighboring glaciers, its frontal position and surface elevation remained relatively unchanged ...
