外文摘要：Species distribution models have been constructed successfully for modelling habitat suitability coastal habitats including salt marsh vegetation. Here, an ensemble model was constructed to assess the recovery of Suaeda Salsa on the two following years after extreme climate events in 2018 such as anomalous high temperatures and reduced precipitation in summer which potentially caused an important decline of this species abundance on the eastern coast of the Liaohe Estuary wetland (Bohai Sea, China). Additionally, the resilience of the ecosystem was evaluated analyzing the evolution of density and morphology indices of S. salsa. Ensemble model exhibits exceptional performance in predicting habitat suitability, achieving scores above 0.95 for both true statistic skill and area under the curve verification criteria. The primary constraints for the recovery of S. salsa were tidal elevation and soil salinity, while sand content was the most influential factor determining its expansion. Two years after the extreme events unsuitable habitat for S. salsa decreased significantly from 61.64% to 34.53%, and a clear recovery was observed in terms of density and above-ground biomass suggesting a potential resilience of salt-marsh vegetation. In contrast, the magnitude of below-ground biomass exhibited a decrease of one-third which is anticipated to result in a diminishment of resilience in S. salsa towards future disturbances given that below-ground reserves serve as the foundation for the tolerance of salt-marsh halophytes. Our results suggest (i) the ensemble model to be a promising tool for supporting managing strategies towards the protection and restoration of areas of salt-marsh halophytes in estuarine wetlands, and (ii) the optimization of freshwater irrigation and the implementation of artificially constructed tidal channels as efficacious strategies for forthcoming restoration endeavors. ? 2024, The Authors.
