Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

A recipe for recovery: diet as a decisive tool in species conservation

Oikos, EarlyView.
Animals consume foods in specific quantities and ratios to meet a multi‐dimensional nutrient target that maximizes their fitness. Attempts to reach this target in an ever‐changing nutritional landscape often influence animal foraging behavior, habitat choice, and food‐web interactions. Consequently, understanding the nutritional ecology of a species is
