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 ...

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
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
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
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 ...
