Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

Integrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Earths Radiation Belts with Safe Zone Orbit

, 2004
Spacecraft orbiting in the Safe Zone, between two and three Earth radii, can be subjected to high levels of harmful radiation as the radiation belts fluctuate in response to space weather events.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Observations of Relativistic Electron Enhancement and Butterfly Pitch Angle Distributions at Low L (<3)

Geophysical Research Letters
Electrons in Earth's outer radiation belt are highly dynamic, with fluxes changing by up to orders of magnitude. The penetration of electrons from the outer belt to the inner belt is one such change observed during geomagnetic storms and was previously ...

Comparing Electron Radiation Belts and New Lessons from Jupiter

, 2019
We revisit comparisons between the electron radiation belts of all of the strongly magnetized planets of the solar system; specifically those of Earth, Jupiter, Saturn, Uranus, and Neptune.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

Archaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Exploring Outer Radiation Belt Losses From the International Space Station

Geophysical Research Letters
The precipitation of energetic electrons from the outer radiation belt plays a crucial role in regulating their flux dynamics and influencing ionospheric properties.
