A network approach to prioritize conservation efforts for migratory birds. [PDF]

open access: yesConserv Biol, 2020
Abstract Habitat loss can trigger migration network collapse by isolating migratory bird breeding grounds from nonbreeding grounds. Theoretically, habitat loss can have vastly different impacts depending on the site's importance within the migratory corridor.

On the normative roles of biodiversity and naturalness in conservation. [PDF]

open access: yesConserv Biol
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.

桂东县冬候鸟种类和迁徙路线调查

open access: yes野生动物学报, 2006
2000-2004年的9-10月,通过对湖南省桂东县冬候鸟种类和迁徙路线的调查,表明桂东县冬候鸟资源较为丰富,主要停歇生境依次为森林灌丛、农田、湿地,共记录鸟类18科61种,其中国家Ⅱ级保护鸟类15种;秋季迁徙期间,冬候鸟从桂东县北面的(?)县和东面的江西省入境,形成“丫”字型迁徙路线,一条迁徙路线是大地→桥头→寒口→增口→新坊→普乐→东洛,另一条迁徙路线是黄洞→寒口→增口→新坊→普乐→东洛,确定了该地区候鸟主要种类和迁徙停歇地,为该地区鸟类资源的有效保护和管理提供了科学依据。

湖南鸟类分布新纪录——靴隼雕

open access: yes野生动物学报, 2021
2020年5月2日,在湖南壶瓶山国家级自然保护区内(29°58′2884″ N,110°52′2633″ E)观察并拍摄到1只鹰科(Accipitridae)鸟类。经查阅文献和对比该鸟的形态特征,鉴定为靴隼雕(Hieraaetus pennatus),为湖南省新纪录鸟种。靴隼雕在中国种群数量稀少,本次的分布位点位于其春季迁徙路线上,对研究其迁徙及其保护具有一定的参考价值。

Filling knowledge gaps in a threatened shorebird flyway through satellite tracking

open access: yesJournal of Applied Ecology, Volume 56, Issue 10, Page 2305-2315, October 2019., 2019
Satellite tracking highlighted coastal habitats that are potentially important for shorebirds but lack ecological information and conservation recognition, such as those in Southern China and Southeast Asia. At the same time, the distributional data of tracked individuals can direct on‐ground surveys at the lesser known sites to collect information on ...

基于公民科学数据分析环志水鸟迁徙连接——以广西北部湾沿海地区为例

open access: yes野生动物学报, 2023
广西北部湾沿海地区为东亚—澳大利西亚候鸟迁徙通道上的重要迁徙停歇地。基于公民科学数据,分析广西北部湾沿海地区记录到的异地环志水鸟与其越冬地、繁殖地及其他停歇地的迁徙连接。结果表明:2020年1月—2021年12月,广西北部湾沿海地区记录到澳大利亚塔斯马尼亚州、俄罗斯楚科奇及中国江苏等11个地点环志的10种水鸟,共计38只,其中,记录到数量较多的种类有勺嘴鹬(Calidris pygmaea)、铁嘴沙鸻(Charadrius leschenaultii)和大凤头燕鸥(Thalasseus bergii ...

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

open access: yesIntegrative 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.

鸟类迁徙若干理论问题

open access: yes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 ...

黄海湿地、鸻鹬鸟类和公众意识教育

open access: yes野生动物学报, 2005
黄海生态区是东亚-澳大利西亚水鸟迁徙路线的重要组成部分,独特的地理位置,优越的栖息环境,使其成为鸻鹬鸟类南、北迁徙的重要通道,对鸻鹬鸟类的成功迁徙、繁殖和种群维持具有举足轻重的作用。从1996年到至今的9年时间,湿地国际-中国办事处每年都要组织专家、保护区的专业人员以及大专院校的专业技术人员对黄海地区沿岸进行实地调查。调查采取样点统计和全面调查相结合的方法,记录实际统计的种类和数量。时间多集中在鸻鹬鸟类北迁期间的4-5月份。根据调查结果分析,北迁期间,估计该地区所支持的鸻鹬鸟类总量高达200万只之多 ...
