Understanding fine‐scale habitat use is essential for conservation of endangered freshwater cetaceans in large rivers. Although Yangtze finless porpoises ( Neophocaena asiaeorientalis ) are frequently observed near mid‐channel islands, their spatiotemporal use of different island geomorphic units remains poorly resolved. From January 2021 to July 2022, passive acoustic monitoring was used to investigate echolocation activity o...

Coastal saline-alkaline soils in China's Yellow River Delta represent vital yet underutilized arable reserves, where crop productivity is severely constrained by dynamic salinity-alkalinity stress, compounded by the scarcity of native stress-adapted biological resources for sustainable remediation. This study addressed this critical gap through in situ isolation of a novel halo-alkaliphilic microalga from saline waters, identi...
