Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States [PDF]
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 [PDF]
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.

, 1989 苍鹭（Ardea Cinerea Linnaeus）是属于鹳形目鹭科的常见涉禽,是典型的沼生鸟类。1985年至1986年,我们在牡丹江鹭岛对其进行了环志迁徙研究。我们共环志雏鸟100只（1985年环志87只1986年环志13只）除4只死亡外,其余全部迁离鹭岛。至1988年底,共回收脚环8只（其中4只在鹭岛回收。回收率达8%）。从回收信息得知,苍鹭越冬迁徙可远达海南省,迁徙路程达3000公里以上,为我国环志鸟类迁徙最远记录 ...

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
Integrative Conservation, Volume 3, Issue 4, Page 382-397, December 2024.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.

, 2022 对影响动物季节性迁徙的因素及其神经机制进行综述，不同类群的动物习性不同，影响迁徙的因素也存在差异，因此较多地探讨了鸟类的迁徙行为。通过研究发现了多种影响动物迁徙的相关神经机制，如光周期视觉神经机制、磁感受神经机制及嗅觉神经机制等。动物迁徙的起源、迁徙原因、如何确定迁徙时间、迁徙导航机制等研究成果，为更深入了解动物的迁徙策略提供了重要的见解，对于进一步研究动物迁徙机制 ...

, 2012 借助于Multinomial Logistic回归模型,文章探讨了产品价格与消费者渠道迁徙路径之间的关系。实证结果发现,产品价格是引起消费者渠道迁徙路径发生改变的重要因素,这不仅可以说明产品价格能引起消费者对于信息搜索渠道和购买渠道的选择,还能反应中国消费者对于消费渠道选择的一种谨慎消费的态度,即为了规避风险 ...

野生动物学报, 1993 迁徙是候鸟生活中主要组成部分。鸟类在漫长的演化过程中逐渐形成一套自己的迁徙习性,如迁徙的天气和时间、迁飞路线、迁飞的速度、迁飞的方式、能量利用、迁飞高度和方向等。迁徙的天气和时间鸟类迁徙的强度在白天和晚间是不同的。这主要取决于气候条件。近几十年利用雷达监测鸟类迁飞与天气的关系的方法已被广泛应用。春天 ...
