Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Individual Variation in Overwintering Strategies of the Great Evening Bat (Ia io) in Subtropical China 中国亚热带地区大足蝠 (Ia io) 越冬策略的个体差异

open access: yesWildlife Letters, Volume 4, Issue 2, Page 66-72, June 2026.
Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

Mistimed surveys lead to underestimated migratory bird impacts from wind farms

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Current guidance and approaches to surveying migratory birds at windfarm developments in Australia are insufficient. Evidence‐based alignment with seasonal presence is needed to improve biodiversity assessment standards, ensuring renewable energy expansion proceeds in a way that better safeguards migratory species and supports global biodiversity and ...

Mountains Without Borders: Scaling up Conservation Success for Snow Leopards

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 1-4, March 2026.
This special issue assembles pioneering research addressing three critical and interconnected challenges: establishing where viable populations persist at range edges, advancing methods to monitor this cryptic species and its prey effectively, and evaluating whether landscapes remain connected across political boundaries.

Conservation grounded in traditional ecological knowledge, culture and hunting

open access: yesPeople and Nature, Volume 8, Issue 1, Page 256-266, January 2026.
Abstract For millennia, traditional hunting practices have provided a means of subsistence for numerous indigenous peoples worldwide. Not only do managed traditional hunting practices perpetuate Traditional Ecological Knowledge (TEK), but they also promote the sustainable utilization of natural resources.

畲族迁徙“外因说”质疑 [PDF]

open access: yes, 1999
文章针对目前学术界所主张的畲族迁徒原因“外因说”提出质疑,指出历史上畲族不断迁徙的原因是极其复杂的,若将畲族迁徙的主要动力归结为外因,则很难对畲族为何形成特殊的移动规律、移动方向以及为何在明清封建压迫更加强化之时反而转向定居等问题作出圆满的解释。文章还指出 ...

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 ...

鸟类学——第十讲 鸟类的迁徙

open access: yes野生动物学报, 1985
鸟类的迁徙是自然界中引人注目的生物学问题。动物的迁徙中,鸟类的迁徙研究一直居于领先地位。凡是在繁殖区和越冬区进行定期迁飞活动的称为候鸟,而迁徙是候鸟一年一度的往返旅行。一般说来,候鸟常常在它分布最冷的地区繁殖,最暖的地区越冬。世界上候鸟约占全部鸟类的三分之一,而参加迁徙活动的鸟类有一百亿只以上。北半球多数的鸟类,每年都参加迁徙,甚至可以飞过赤道进入非洲,澳洲和拉丁美洲越冬;但是,南半球的鸟类 ...

Is the Asian Openbill Migratory? Population Status and Habitat Use in Eastern Nepal 钳嘴鹳是否迁徙?尼泊尔东部地区的种群现状与栖息地利用

open access: yesWildlife 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.
