A mosaic of colors: The influence of biotic and abiotic factors shaping flower color diversity across a tropical mountain ecosystem

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Flower color diversity within communities is shaped by biotic and abiotic factors. Pollinators often prefer specific colors, and floral pigments also help protect against abiotic factors such as ultraviolet (UV) radiation, precipitation, and temperature.

DarkGEO: a large-scale laser-interferometric axion detector

New Journal of Physics
Axions and axion-like particles (ALPs) are leading candidates for dark matter. They are well motivated in many extensions of the standard model and supported by astronomical observations.

Radio-loud Magnetars as Detectors for Axions and Axion-like Particles

, 2012
We show that, by studying the arrival times of radio pulses from highly-magnetized transient beamed sources, it may be possible to detect light pseudo-scalar particles, such as axions and axion-like particles, whose existence could have considerable ...

Microsatellite‐Based Genetic Analysis of a Wild Alpine Bumblebee and the Environmental Drivers of Its Genetic Diversity

Ecology and Evolution, Volume 16, Issue 1, January 2026.
High genetic diversity was detected in 539 B. kashmirensis individuals from 36 populations in Qinghai Province using 15 SSR markers. STRUCTURE, UPGMA, and PCoA analyses revealed east–west genetic clustering of populations. Environmental factors such as latitude, longitude, solar radiation, and vapor pressure influence genetic diversity. ABSTRACT Bombus

ALP-ine quests at the LHC: hunting axion-like particles via peaks and dips in $$ t\overline{t} $$ production

Journal of High Energy Physics
Abstract We present an analysis of the sensitivity of current and future LHC searches for new spin-0 particles in top–anti-top-quark $$ \left(t\overline{t}\right) $$ t t

Reintroduction Without Genetic Bottlenecks: Preserving Diversity in Restored Populations of the Critically Endangered Riverine Shrub Myricaria germanica

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Anthropogenic river regulation has severely reduced habitats of alpine floodplain specialists such as Myricaria germanica. Analyses of natural and restored populations along the Isar and Lech Rivers revealed that reintroduction from a single, genetically variable source can maintain local genetic diversity, with only modest differentiation from the ...

Probing axion-like particles at the Electron-Ion Collider

Journal of High Energy Physics
The Electron-Ion Collider (EIC), a forthcoming powerful high-luminosity facility, represents an exciting opportunity to explore new physics. In this article, we study the potential of the EIC to probe the coupling between axion-like particles (ALPs) and ...

Irregularity in gamma ray source spectra as a signature of axionlike particles

, 2012
Oscillations from high energy photons into light pseudoscalar particles in an external magnetic field are expected to occur in some extensions of the standard model.
