Recent vegetation shifts in the French Alps with winners outnumbering losers

Journal of Ecology, EarlyView.
Analysing 11 million records of 4250 French Alps plant species over 30 years shows that one‐third expanded their range, dominated by thermophilic and fast‐colonizing species, while 13% declined. Most species showed little response, with potential shifts lagging behind climate change. Our study deepens our understanding of the complex dynamics of recent

Aiming for tops of ALPs with a muon collider

Journal of High Energy Physics
Future muon colliders with center-of-mass energy of O $$ \mathcal{O} $$ (1 − 10) TeV can provide a clean high-energy environment with advantages in searches for TeV-scale axion-like particles (ALPs), pseudo-Nambu-Goldstone bosons associated with ...

Cosmic Analogues of the Stern-Gerlach Experiment and the Detection of Light Bosons

, 2008
We show that, by studying the arrival times of radio pulses from highly-magnetized pulsars, it may be possible to detect light spin-0 bosons (such as axions and axion-like particles) with a much greater sensitivity, over a broad particle mass range than ...

Revisiting the SN1987A gamma-ray limit on ultralight axion-like particles [PDF]

, 2014
We revise the bound from the supernova SN1987A on the coupling of ultralight axion-like particles (ALPs) to photons. In a core-collapse supernova, ALPs would be emitted via the Primakoff process, and eventually convert into gamma rays in the magnetic ...

CAMELIA: Enhancing species assemblage predictions by integrating structural and functional indices: A case study on plant communities in the French Alps

Methods in Ecology and Evolution, EarlyView.
Abstract Addressing the challenge of predicting biodiversity requires models that fully capture the complex dynamics of species and communities. While species distribution models (SDMs) predict individual species' distributions based on environmental variables, they often fail to reconstruct realistic communities.

Small instantons and the post-inflationary QCD axion in a special product GUT

Journal of High Energy Physics
We present a new framework of grand unification that is equipped with an axion solution to the strong CP problem without a domain wall problem when the Peccei-Quinn (PQ) symmetry is spontaneously broken after inflation.

ALPINIST: Axion-Like Particles In Numerous Interactions Simulated and Tabulated

Journal of High Energy Physics, 2022
Proton beam dump experiments are among the most promising strategies to search for light and feebly interacting states such as axion-like particles (ALPs). The interpretation of these experiments is however complicated by the wide range of ALP models and

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

High quality QCD axion via electric-magnetic duality

Journal of High Energy Physics
We propose a novel paradigm for the QCD axion with high-quality Peccei-Quinn (PQ) symmetry on the basis of electric-magnetic duality in the conformal window of a supersymmetric gauge theory.

Lights and Landscapes: More‐Than‐Human Nature in Near‐Death Experiences as Reconciliation in a Time of Ecological Crisis

Dialog, EarlyView.
ABSTRACT This paper explores lights and landscapes as depicted in near‐death experiences (NDEs). NDEs are specific experiences, which human beings with a (perceived) close brush with death may have and later recall, often including seeing a brilliant light and sometimes traveling to unearthly dimensions, which may or may not include landscapes.
