Many Plant Species in Europe Have Limited Capacity to Track Climate Change

open access: yesDiversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim No or unlimited dispersal capacities of species are commonly assumed in species distribution models (SDMs) used to assess potential impacts of climate change on biodiversity. However, these assumptions may lead to overly pessimistic or optimistic predictions.

Analysis of nocturnal urban heat advection using crowd weather stations

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 151, Issue 773, October 2025 Part B.
The urban heat island is often studied under calm conditions, where its development is strongest. However, effects of wind speed and direction need to be considered for a full understanding. We study the effects of urban heat advection in the urban canopy layer using crowd weather stations. Wind causes increased exposure to urban heat for areas located

Modelling the system behaviour of wet snow avalanches using an expert system approach for risk management on high alpine traffic roads [PDF]

open access: yes, 2005
The presented approach describes a model for a rule-based expert system calculating the temporal variability of the release of wet snow avalanches, using the assumption of avalanche triggering without the loading of new snow.

Volcano‐Tectonic Crisis of Mayotte (2018–2022): A Deformation Model for Geodetic Applications

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Volcano‐tectonic unrest during the 2018–2022 crisis of Mayotte (Comoros archipelago) generated an island‐wide surface displacement reaching ∼ ${\sim} $20 cm, with a relative (internal) deformation of the island of ∼ ${\sim} $10 cm. Correcting for these displacements, which exceed the required accuracy of geodetic network reference coordinates,
