Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States
Conservation Biology, Volume 39, Issue 5, October 2025.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

On the normative roles of biodiversity and naturalness in conservation
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Nature is an opaque concept. Consequently, the term biodiversity conservation has replaced nature conservation in most conservation contexts. We review the conceptual indeterminacies that plague the terms nature and natural but then show that comparable difficulties plague biodiversity.

Wildlife Letters, Volume 3, Issue 3, Page 109-117, September 2025.We found that the Asian Openbill primarily roosted near waterbodies and frequently used farmland habitats, with significantly higher populations observed during the breeding season. Farmland and wetland areas exhibited a positive effect on the species' habitat use.

野生动物学报, 2006 2003年1月至2006年3月,对福建漳江口红树林国家级自然保护区水鸟资源进行了调查,共发现水鸟33种 （亚种）8 442只,其中小白鹭、绿翅鸭、红嘴鸥数量是本调查期所调查到数量最多的3种水鸟,分别占调查总数的 16.5％、23．5％和10.0％。另外,冬候鸟是本保护区水鸟中占优势的生态类群。随着保护区滩涂的高利用率,使水鸟食物种类及数量急剧减少,从而严重影响水鸟的栖息生存。因此,加强对保护区规范建设、科学管理和充分协调保护与利用之间的关系至关重要。

野生动物学报, 2020 2016—2018年11—12月，对西安市越冬水鸟种类、数量和分布进行了调查。结果表明，共记录到72种，27 357只，隶属10目16科45属。约占陕西省水鸟种数65.5%，约占全国的26.6%。受保护的鸟类有16种，包括国家Ⅰ级保护2种，国家Ⅱ级保护2种，省级重点保护12种。依鸟类区系划分，古北界种类53种，东洋界种类9种和广布种10种。其中鸻形目最多有6科28种，其次是雁形目共1科23种，但数量上鸻鹬类比雁鸭类相差很大。这可能与河流湿地适合鸻鹬类停歇地的滩涂面积大小有关。渭河湿地的多样性是最高的为1.

Reading Research Quarterly, Volume 60, Issue 1, January/February/March 2025.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 ...
