When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Preliminary Studies on the Nestling Growth,Hatching and Reproductivity of Three Specices of Herons [PDF]

open access: yes, 2009
本实验于2006~2008年间在厦门的鸡屿、大屿、大兔屿,漳浦的菜屿列岛和福鼎的日屿岛初步调查了黄嘴白鹭(Egrettaeulophotes)、白鹭(Egrettagarzetta)和池鹭(Ardeolabacchus)的繁殖生态,取得了三种鹭的窝卵数、卵的大小、孵化率和成活率等生物学数据,对白鹭进行了鹭鸟卵和雏鸟的识别实验,对白鹭和池鹭研究了窝卵数人为改变对亲鸟繁殖行为及雏鸟成活的影响,对黄嘴白鹭卵进行了人工孵化和雏鸟人工养殖的探讨。 三种鹭的窝卵数分别是白鹭3.69±0.70枚(n=16),池鹭3 ...

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, EarlyView.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Studies on Migration of Bursaphlenchus xylophilus and the Extracts from medium cultured with Botrytis cinerea and it's inducing activity to B.xylophilus [PDF]

open access: yes, 2007
摘要“松材线虫早期检测管诊断管”能从松树上诱引到松材线虫(Bx),为了研究其作用的机理,本论文设计了一条新的思路,分别以灭菌的淡水沙和水琼脂平板为基质,研究了各种因素对Bx移行的影响,并从灰葡萄孢发酵液中逐级分离提取各种组分,以滤纸片法分析其中对Bx移行起诱引作用的物质。主要结果如下:病木对Bx的诱引力较强,经高压灭菌后诱引能力虽有所下降,但差值不大,说明在病木中对Bx起诱引作用的物质并没有因高压灭菌而完全失去,这与某些人“吸引物质为挥发性物质”的推测相左;但松皮浸出液对Bx并没有什么明显的吸引作用 ...

Extent of threats to marine fish from the online aquarium trade in the United States

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...

Mechanisms of Heavy metals enriching and excreting in Egretta eulophote and Impact of Colonial Breeding on Heronry Soils [PDF]

open access: yes, 2010
本研究采用电感耦合等离子质谱(ICP-MS)对取得的相关样品进行了钒(V)、铬(Cr)、锰(Mn)、镍(Ni)、铜(Cu)、锌(Zn)、砷(As)、硒(Se)、镉(Cd)和铅(Pb)等10种重金属元素含量的测定。 为了研究黄嘴白鹭体内各重金属富集的主要部位、重金属排除的机制及在其食物链中富集规律,我们对厦门大屿岛白鹭自然保护区内人工养殖过程中自然死亡的8只黄嘴白鹭(Egrettaeulophotes)(约30日龄)的肝脏、肾脏、肌肉、心脏、骨骼、卵壳和羽毛等组织器官以及饲喂的水样、食物 ...

Non‐Passerine Birds in Zoos: A Global Approach on Distribution Patterns of Threatened Birds in Zoological Institutions 动物园中非雀形目鸟类:全球动物机构中受威胁鸟类的分布模式研究

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 600-615, December 2025.
Only 1541 (34.2%) of 4503 recognized non‐passerine bird species are held in ZIMS institutions worldwide. Approximately ~83% of the species kept globally are classified as non‐threatened and ~16% as threatened. To improve the conservation of threatened birds, a shift toward keeping threatened species should be considered within ex situ management ...

Novel Natural History Observations on the Reproductive Biology of King Cobra (Ophiophagus hannah) From Yunnan Province, China 云南省眼镜王蛇繁殖生物学的野外观察

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 523-526, December 2025.
Here we report three cases of nesting behavior in Yunnan Province, China. Our observations confirmed the presence of multi‐individual participation during the nest guarding, and this behavior was associated with an exceptionally high clutch size. ABSTRACT Although the King Cobra (Ophiophagus hannah) has received considerable conservation attention ...
