Coupled Thermosphere–Ionosphere Dynamics During the 17 January 2013 Storm: GITM–TIDAS Comparison With Millstone Hill ISR Measurements

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This article analyzes a weak geomagnetic storm on January 17–18, 2013, using a first‐principles model (Global Ionosphere Thermosphere Model (GITM) with an empirical assimilative ionospheric model (TIDAS), evaluated against observations in the form of Millstone Hill (MH) incoherent scatter radar (ISR) altitude profiles and global navigation ...

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...

Mapping Global GNSS Vertical Velocities to Solid Earth Figure Change

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Earth's figure evolves in response to glacial isostatic adjustment (GIA), surface‐mass redistribution, and rotational and mantle‐driven processes. While temporal changes in the geoid's flattening are monitored through low‐degree gravity field harmonics, the geometric response of the solid Earth can be assessed independently from GNSS ...

Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

open access: yesJournal of Animal Ecology, Volume 95, Issue 9, Page 1539-1557, September 2026.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

Fine‐scale spatial variation in eastern grey squirrel melanism across a complex urban landscape

open access: yesJournal of Animal Ecology, Volume 95, Issue 9, Page 1778-1792, September 2026.
By sampling 197 parks, the study demonstrates how natural geography creates divergence within cities. The findings reveal that the St. Lawrence River and its tributaries act as barriers, disrupting urban melanism clines in grey squirrels. Ultimately, the research indicates that natural features still dictate evolutionary rules in anthropogenic ...
