Journal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.Abstract Accurate microscale flow simulations are essential for assessing wind characteristics in complex terrain. This study evaluates a large ensemble of multiscale simulations, including large‐eddy simulations (LES), using the Weather Research and Forecasting model (WRF) over Perdigão, Portugal, driven by boundary conditions from multiple global ...

Ecography, Volume 2025, Issue 8, August 2025.The species–area relationship (SAR) on islands describes how the numbers of species increase with increasing island size (or island‐like habitat, such as lakes). Despite its conceptual importance, there is considerable uncertainty surrounding its shape in freshwater lakes, as well as the potential mechanisms that underlie the SAR.
