On the Importance of Expert‐Informed Variable Selection in Species Distribution Modelling

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Species Distribution Models (SDMs) are widely used to map species distribution and predict future responses to climate change. While the risk of selecting biologically non‐relevant predictors has been raised, numerous studies continue to fully rely on statistical approaches to automatically select predictors solely focusing on climate ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration

open access: yesPlant-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‐
