A High‐Efficiency Multivariable TEC‐SOFTS Model for Ionospheric TEC Prediction: Validation Over China Area During Low and High Solar Activity Periods

Space Weather, Volume 24, Issue 5, May 2026.
Abstract The ionospheric Total Electron Content (TEC) is a key parameter for characterizing the ionospheric properties. In this study, an efficient multivariable time series prediction model, TEC‐Series Core Fusion and efficient multivariable time series (TEC‐SOFTS), was constructed by combining multiple geomagnetic and solar activity indices ...

Introducing Reflected GNSS TEC Data Into ANCHOR Ionospheric Data Assimilation Model

Space Weather, Volume 24, Issue 5, May 2026.
Abstract ANCHOR is a novel data assimilation (DA) algorithm developed at the U.S. Naval Research Laboratory to improve ionospheric nowcasting by increasing accuracy and decreasing computational cost. As a parameterized DA model, ANCHOR represents the ionosphere using physical parameters such as the F2 layer peak (Nm $Nm$F2), which characterizes a ...

Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Climatic origin and plasticity shape emergence timing and fitness in bees and wasps under experimental climate regimes

Functional Ecology, Volume 40, Issue 5, Page 1461-1474, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming threatens the persistence of insect populations by forcing them to adjust their phenology—responses that may be constrained by local adaptation and involve physiological trade‐offs.

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...
