A link between increased temperature and avian body condition in a logged tropical forest

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

鸟类环志漫谈

open access: yes, 2003
什么是鸟类环志鸟类环志就是把带有号码的环形标志(鸟环)戴到鸟腿上的一种标记方法。除脚环外,还有颈环、翅环和鼻环,但这些并不常用。鸟环通常用金属制作,若用彩色塑料片制作则称彩环,可远距离识别环志鸟而不必捕获,适用于长腿鸟类。环志方法在国外已有百余年历史,

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

鸟类环志的简介

open access: yes, 1983
(一)环志的意义鸟类环志(Bird-Banding)是获得有关鸟类迁徙资料的一种科学方法。通过环志可以了解和研究鸟类迁徙、散布、季节运动、归巢能力、死亡率、存活率、寿命、种群大小、种群结构、配育经久性、地点和场所、日活动,以及有关生境、行为等方面的基本数据。从环志所取得的大量资料,起码有两个方面的意义 ...

浙江省鸟类多样性与区系分析

open access: yes野生动物学报, 2019
综合文献报道以及本课题组积累的资料,严格核定近年来的浙江鸟类新增种以及全省各鸟种的居留型和区系类型,并按照鸟类最新分类系统编制《浙江省鸟类多样性名录》,这对于理解地区鸟类多样性及其分布现状具有重要意义。结果显示:浙江省鸟类共计22目87科266属519种及26亚种,比《浙江鸟类名录更新》多36种及2亚种。全省鸟类以雀形目为主(236种),非雀形目鸟类以鸻形目种数(86种)最多。浙江省水鸟共计168种,其中鸻形目种数最多(83种);海鸟共计42种,其中鸥科种数最多(28种);猛禽共计52种 ...

Effects of landscape context on avian specialist response to increased surface temperature in protected areas

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

鸟类的孵卵行为

open access: yes, 1991
鸟类是唯一的恒温产卵动物,其卵内胚胎需在接近体温的条件下才能形成和发育,因此孵卵是鸟类繁衍生存的关键。大多数鸟类由雌鸟孵卵,雄鸟则承担衔食饲喂雌鸟的任务。但在以雌鸟为主的孵卵“队列”中,却有许多巧夺天工的自然选择“佳作”。生活在云南南部的犀鸟,能用衔来的泥土杂物混上胃内分泌物,将孵卵雌鸟的洞口严加封闭,仅留可供雌鸟伸出嘴尖取食的缝隙,卵在雌鸟胸部散放的体热下孵化,经28—40天后,当雏鸟即将出飞时,雌鸟才获准“破门而出”重获自由。犀鸟这种“金屋藏娇 ...
