Unveiling the Hidden Drivers: How Vegetation Cover, Season and Forest Management Shape the Soil Microbial Community in Two Mediterranean Forest Ecosystems

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Forest management affects microbial community composition depending on forest type. Vegetation type has the strongest effect on microbial composition, while management alters community structure without affecting function, highlighting the importance of vegetation in forest soil ecosystem dynamics.

Juno Observations of Langmuir Waves in Association with Interplanetary Shocks from ~1.3 to ~5.4 au

The Astrophysical Journal Letters
Langmuir waves are often observed upstream of planetary bow shocks and interplanetary (IP) shocks. Waveform capture (WFC) measurements, obtained during Juno’s cruise phase, reveal the occurrence of Langmuir waves, as well as other wave modes, in ...

Mild Warming Induces Divergent Plastic Responses in Gene Expression Among Populations of a Temperate Butterfly

Molecular Ecology, Volume 35, Issue 7, April 2026.
ABSTRACT In response to potentially stressful conditions, for example due to climate change, organisms can move, adjust through phenotypic plasticity and evolve. Evolution can act on mean trait values, or on plasticity itself. Whether phenotypic plasticity, evolution, or evolution of plasticity is the dominant response to environmental change is still ...

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...

Prospects for Detection of Exoplanet Magnetic Fields Through Bow-Shock Observations During Transits

, 2010
An asymmetry between the ingress and egress times was observed in the near-UV light curve of the transit planet WASP-12b. Such asymmetry led us to suggest that the early ingress in the UV light curve of WASP-12b, compared to the optical observations, is ...

Electron Acceleration by Multiple Fast Fermi Reflections at Earth’s Bow Shock

The Astrophysical Journal
The generation of energetic particles in the Universe is an important topic in astrophysical and space physics. Although the diffusive shock acceleration has been acknowledged to play an essential role in particle acceleration, the injection problem has ...

Shock formation around planets orbiting M-dwarf stars

, 2011
Bow shocks can be formed around planets due to their interaction with the coronal medium of the host stars. The net velocity of the particles impacting on the planet determines the orientation of the shock. At the Earth's orbit, the (mainly radial) solar

Multimission Observations of Relativistic Electrons and High-speed Jets Linked to Shock-generated Transients

The Astrophysical Journal Letters
Shock-generated transients, such as hot flow anomalies (HFAs), upstream of planetary bow shocks, play a critical role in electron acceleration. Using multimission data from NASA’s Magnetospheric Multiscale and ESA’s Cluster missions, we demonstrate the ...

Compressive Structures in the Foreshock of Collisionless Shocks

The Astrophysical Journal Letters
Collisionless shocks are fundamental accelerators of energetic particles, yet the observations of nonlinear foreshock structures, which are essential in acceleration processes, differ significantly between interplanetary (IP) shocks and planetary bow ...

Classification of magnetized star--planet interactions: bow shocks, tails, and inspiraling flows

, 2015
Close-in exoplanets interact with their host stars gravitationally as well as via their magnetized plasma outflows. The rich dynamics that arises may result in distinct observable features.
