Description of a new clutch of Nanhsiungoolithus chuetienensis reveals possible parataxonomic affiliation of dromaeosaurid egg

Xufeng Zhu, Yu Li, Qiang Wang, Rui Qiu et autres

A new clutch of a rarely described oospecies, Nanhsiungoolithus chuetienensis is detailed in this work. The clutch contains 14 eggs radially arranged in two concentric rings, representing the most complete clutch of N. chuetienensis yet described. The morphology and microstructure of this …

Variation characteristics of joint frequency for compound extreme hydrological events under the background of urbanization in the Taihu Basin

Chen Song, Qiang Wang, Youpeng Xu, Yi He et autres

随着气候变化和城镇化影响的加剧，极端复合水文事件频发，威胁人民生命财产安全，揭示极端水文事件的联合频率特征及其变化机制对水安全保障至关重要。本研究基于联合分布理论分析了太湖平原地区极端雨洪、洪潮和雨潮复合事件的联合频率变化特征，揭示了不同城镇化阶段极端水文事件遭遇概率的变化规律。结果表明：相比城镇化早期，城镇化高速期极端水位、潮位和降雨等水文要素均有所增加，年最大1日降水增幅达15%以上，年最大1日水位增幅达6%以上；武澄锡虞区各水文要素的均值均大于阳澄淀泖区。武澄锡虞区遭遇极端雨洪复合事件的风险较大，而阳澄淀泖区遭遇极端雨潮和洪潮复合事件的风险相对较大。太湖平原地区极端水文复合事件受到城镇化程度的显著影响，城镇化高速期遭遇复合极端水文事件的概率均增大约2倍，其中武澄锡虞区重现期变化率大于阳澄淀泖区。研究结果可为太湖平原及类似快速城镇化地区的工程水文设计和防洪减灾提供科学参考。

Low dinosaur biodiversity in central China 2 million years prior to the end-Cretaceous mass extinction

Fei Han, Qiang Wang, Huapei Wang, Xufeng Zhu et autres

Whether or not nonavian dinosaur biodiversity declined prior to the end-Cretaceous mass extinction remains controversial as the result of sampling biases in the fossil record, differences in the analytical approaches used, and the rarity of high-precision geochronological dating of dinosaur fossils. Using …
