The Link Between Range Size, Niche Specialisation and Diversification in One of the Most Successful Avian Radiations, the New World Flycatchers (Tyrannoidea)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Range size constitutes a fundamental characteristic of every species and is commonly believed to influence diversification rates. This relationship is potentially dependent on the mode of speciation and other intrinsic factors, including geographic setting and species attributes. Yet, not only the size of the geographic range, but also the

VLF waves from ground‐based transmitters observed by the Van Allen Probes: Statistical model and effects on plasmaspheric electrons

Geophysical Research Letters, 2017
Whistler mode very low frequency (VLF) waves from powerful ground‐based transmitters can resonantly scatter energetic plasmaspheric electrons and precipitate them into the atmosphere.

Molecular Phylogeny of Mouse‐Tailed Bats (Chiroptera: Rhinopomatidae): Evolutionary Insights Into a Desert‐Dwelling Family

Zoologica Scripta, Volume 54, Issue 6, Page 800-816, November 2025.
ABSTRACT The family Rhinopomatidae comprises six species of mouse‐tailed bats within the genus Rhinopoma, inhabiting arid regions of the Old World from western Africa to Myanmar. While their phylogenetic relationships have been explored through morphology and molecular analyses, many populations still remain insufficiently studied using molecular ...

Chorus Acceleration of Relativistic Electrons in Extremely Low L‐Shell During Geomagnetic Storm of August 2018

Geophysical Research Letters, 2020
Based on data from the Van Allen Probes and ZH‐1 satellites, relativistic electron enhancements in extremely low L‐shell regions (reaching L∼3) were observed during August 2018 major geomagnetic storm (minimum Dst≈−190 nT). Contrary to what occurs in the

Precession Affects the Timing and Duration of Summer and Rainy Season in East Asia

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract East Asia is a densely populated center whose economic and agricultural activities depend heavily on a suitable seasonality of temperature and precipitation. Geological records, like speleothems and lake sediments, show precession drives orbital‐scale temperature and precipitation variations in this region but lack seasonal detail.

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

Fine Structure of Relativistic Electron Precipitation Driven by EMIC Waves: CIRBE/REPTile‐2 Measurements and Physical Implications

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Electromagnetic ion cyclotron (EMIC) waves are commonly observed electromagnetic emissions in Earth's magnetosphere and are widely considered to efficiently scatter relativistic electrons into bounce loss cones. However, their precise scattering effects remain highly debated due to limited energy coverage and coarse resolution of previous ...

Extra Zebra Stripes Observed by Macao Science Satellite‐1 in the Inner Radiation Belt

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Zebra stripes, characterized by periodic banded structures in the energy‐L shell spectra of energetic electrons in the Earth's inner radiation belt, are understood to result from the azimuthal drift of electrons perturbed by prompt electric field perturbations.
