Demographic and Structural Variability Modulate Growth Dynamics in European Beech Primary Forests

Global Change Biology, Volume 32, Issue 5, May 2026.
Climate change is increasing drought and heat stress on European beech (Fagus sylvatica L.), causing widespread tree vitality losses and growth declines across Europe. Using a large tree ring network from montane primary beech forests, we found that trees of various ages and sizes respond differently to climate warming, leading to contrasting within ...

Coloring and density theorems for configurations of a given volume

Proceedings of the London Mathematical Society, Volume 132, Issue 3, March 2026.
Abstract This is a treatise on finite point configurations spanning a fixed volume to be found in a single color‐class of an arbitrary finite (measurable) coloring of the Euclidean space Rn$\mathbb {R}^n$, or in a single large measurable subset A⊆Rn$A\subseteq \mathbb {R}^n$.

The Interplay of Climate Change, Urbanisation, and Species Traits Shapes European Butterfly Population Trends

Global Ecology and Biogeography, Volume 35, Issue 2, February 2026.
ABSTRACT Aim To examine how butterfly population trends respond to climate change and urbanisation at a continental scale, and whether responses differ between urban and rural environments. Location 869 sites across 12 European countries, spanning six bioclimatic zones. Time Period 1976–2021. Major Taxa Studied Butterflies (Lepidoptera).

SubeYa: A System for Predicting Passenger Demand at Train Stations

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study addresses the challenges of urban congestion and long wait times within EL1ML by introducing SubeYa, a web‐based platform designed to predict passenger demand. By utilizing the Prophet predictive model and analysing historical data from 2019 to 2025, the system achieves a global MAE of 259.10.

On QSPR Modeling and SAW‐Based Ranking of Laryngeal Cancer Drugs Using Temperature‐Based Topological Indices and Support Vector Regression

Complexity, Volume 2026, Issue 1, 2026.
QSPR modeling offers an effective tool for predicting the physicochemical properties of pharmaceutical molecules by applying molecular descriptors. In this research paper, a new QSPR method based on the temperature‐based topological indices in graph theory is presented for analyzing selected drugs that are relevant to laryngeal cancer.
