Oikos, EarlyView.Phenology plays a central role in regulating energy flow and nutrient cycling, yet remains insufficiently integrated into biodiversity–ecosystem functioning frameworks. This gap is especially relevant in strongly seasonal systems, where community‐wide synchrony in leaf litterfall may arise from either temporal niche differentiation among species or ...

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures
River Research and Applications, EarlyView.ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Seismic Fragility Analysis of Gravity Dams Considering the Fuzziness of Damage States Thresholds
工程科学与技术, 2020 Since the evolution of the structural damage states is a gradual transitional process and the fuzziness of cognition, the thresholds of damage states of the gravity dams are fuzzy, which will affect the evaluation results of damage states of gravity dams.
