Living in the Hedge: Farmland Reptile Diversity Is Driven by Hedgerow Structural Complexity and Landscape Connectivity

Animal Conservation, Volume 28, Issue 6, Page 817-831, December 2025.
Agricultural intensification is responsible for biodiversity decline, but high‐quality field margins may mitigate these effects. We studied reptile species richness in a farming landscape in western France with a focus on hedgerows structure and density.

On General Axial Gauges for QCD [PDF]

, 1998
General Axial Gauges within a perturbative approach to QCD are plagued by 'spurious' propagator singularities. Their regularisation has to face major conceptual and technical problems. We show that this obstacle is naturally absent within a Wilsonian or '

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

Plant-Environment Interactions, Volume 6, Issue 5, October 2025.
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Optical probes of the quantum vacuum: The photon polarization tensor in external fields

, 2012
The photon polarization tensor is the central building block of an effective theory description of photon propagation in the quantum vacuum. It accounts for the vacuum fluctuations of the underlying theory, and in the presence of external electromagnetic
