Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the

鄂尔多斯遗鸥国家级自然保护区湿地鸟类群落结构及其对水环境的响应
2016—2019年对内蒙古鄂尔多斯遗鸥国家级自然保护区的鸟类物种多样性及群落结构进行了调查,同时对水质指标进行了年度监测。保护区共记录到鸟类51种,隶属于9目13科,其中夏候鸟23种,旅鸟24种,留鸟4种。在鸟类区系方面,古北界鸟种1种,广布种50种。湿地鸟类群落物种丰富度、多样性指数和均匀度指数均从2016年开始呈下降趋势,2018年开始回升,但未恢复到初始水平。水质指标测量结果显示,保护区水环境总体质量较差。虽然鸟类多样性和污染物综合指标变化相关性并不显著,但是从总体上看 ...

Abstract Previous studies uncover that vocabulary knowledge may be related to compound structure awareness (the awareness of relational structure embedded in compound words), and they both contribute to reading comprehension. Yet, limited studies have examined the dynamic relationship between vocabulary knowledge and compound structure awareness, or ...

Guanotrophy: Waterbirds Pay for Using Resources at Their Wintering Habitats 鸟粪营养学 :水鸟在越冬栖息地使用资源后留下回报
Significant waterbird colonisation was recorded in the wintering period (October through March in 2018–2019 and 2019–2020) in wetlands on Central Asian and East Australasian Flyways. Different limnochemical conditions influenced nitrate and phosphate concentrations.
