Studies on sleep patterns and sleep homeostasis in birds:An ecological approach [PDF]

open access: yes, 2021
Sleep is a complex phenomenon that consists of two completely different and alternating states, slow-wave sleep (SWS) and rapid-eye-movement sleep (REM sleep).

An ecologically sound and participatory monitoring network for pan-Arctic seabirds. [PDF]

open access: yesConserv Biol
Abstract In a warming Arctic, circumpolar long‐term monitoring programs are key to advancing ecological knowledge and informing environmental policies. Calls for better involvement of Arctic peoples in all stages of the monitoring process are widespread, although such transformation of Arctic science is still in its infancy.

On the normative roles of biodiversity and naturalness in conservation

open access: yesConservation Biology, EarlyView.
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.

Finding floral and faunal species richness optima among active fire regimes

open access: yesConservation Biology, EarlyView.
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

The structure and phylogenesis of olfactory receptor gene OR14J1 in ardeid birds [PDF]

open access: yes, 2016
动物嗅觉受体(OlfactoryReceptor,OR)分布于嗅觉上皮而直接影响着嗅觉功能。哺乳类OR基因家族中位点相连于主要组织相容性复合体(MajorHistocompatibilityComplex,MHC)的基因比例最大,且邻近MHC的最常见OR14J1基因具有与MHC相关联的作用,动物通过嗅觉选择配偶能够有利于提高其免疫力和适应性。鸟类嗅觉以往被认为较弱而没有得到重视,近年来有关鸟类嗅觉基因的研究正在开始起步。 本论文在设计鹭科鸟类OR14J1通用引物的基础上,扩增鹭科鸟类OR14J1片段 ...

Evaluating protected areas’ coverage of threats to terrestrial biodiversity

open access: yesConservation Biology, EarlyView.
Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

The study of Mitochondrial DNA Gene Rearrangement in 4 species of birds(Aves: Falconiformes) [PDF]

open access: yes, 2016
线粒体控制区由于进化速率快,被作为分子标记广泛应用于种群遗传学和保护生物学等领域的研究。但最近在许多鸟类的线粒体中都发现控制区存在重复拷贝,并且2个控制区拷贝之间的碱基相似度较高。因此在扩增其中一个控制区基因时可能受到另一个控制区的干扰,而对研究结果产生影响。本研究主要针对隼形目鸟类线粒体DNA(mtDNA)基因组中控制区重复及由此产生的基因重排现象进行研究,初步探讨控制区重复和基因重排产生的过程和机制。 本次实验首次对鹰科中的白头鹞(Circusaeruginosus)、日本松雀鹰 ...

Applying Bergmann's Rule to Species Conservation Planning 贝格曼法则在物种保护规划中的应用

open access: yesIntegrative Conservation, Volume 4, Issue 2, Page 120-125, June 2025.
Although Bergman's rule has extensively been studied, its implications in species conservation have not been clear, especially in the context of climate change (global warming). Here, we discuss the potential applications of the “rule” based on IUCN's (2022) Red List and suggest species' body size to be an important ecological indicator in future long ...

Agricultural Lands as Important Wintering Habitats for the Critically Endangered Yellow‐Breasted Bunting in Nepal 尼泊尔农业用地作为极危黄胸鹀的重要越冬栖息地

open access: yesIntegrative Conservation, Volume 4, Issue 2, Page 134-142, June 2025.
Our study addresses the significant knowledge gap regarding the wintering population and habitat utilization of the Yellow‐breasted Bunting (Emberiza aureola) in Nepal, providing crucial insights that can aid in the conservation of this critically endangered species in wintering grounds.

Including the urbanization gradient in people‐centered wildlife conservation in Amazonia

open access: yesConservation Biology, Volume 39, Issue 3, June 2025.
Abstract Conservation policy in the Amazon traditionally focuses on rural areas, overlooking the socioecological roles of urban populations. This oversight can hinder sustainability by neglecting rural–urban connections. We compared the prevalence and quantity of wild meat consumed, bartered, and traded commercially in rural, peri‐urban, and urban ...
