Review of the Cretaceous avian diversity of Antarctica:a changing scenario for the evolution of early Neornithine birds
2024年
The worldwide record of Cretaceous Neornithes and Neornithine-like birds is both controversial and poorly understood.However,in recent years,the Antarctic continent has yielded a substantial number of Maastrichtian avian specimens,contributing significantly to our understanding of the early evolution of this group.Simultaneously,the keen interest and collaborative efforts of various paleornithologists have resulted in a wealth of knowledge,which we have thoroughly reviewed,updated,and discussed in the context of recent discoveries.

Birds’Diversity in Kalfou Forest Reserve and Its Peripheral Zone, Far North, Cameroon
2024年
The Far North Region of Cameroon is home to a great diversity of bird species, which unfortunately remains very little explored. This work was initiated to establish an inventory of birds and the factors affecting their diversity and distribution for sustainable management in the Kalfou Forest Reserve (KFR) and its periphery. Two methods were used for sampling, linear strip transects from which direct counts and indirect observations were made and the mist netting to complement the first. In total, 2525 birds were observed, including 149 species, belonging to 20 orders and 55 families. Accipitridae had the greatest number of species (11). The species richness was greater in the KFR (117 species) compared to the periphery (95 species). The specific richness was higher in wooded savannah compared to other habitats. Shannon index was significantly higher in the KFR (3.99) compared to that obtained in the periphery (3.80). The value of the Simpson index was higher on the outskirts of the KFR than on the periphery. The indices of species diversity were greater in the wooded savannah compared to other vegetation types. The seasons had no influence on bird diversity. Among the human activities encountered, the pressure indices were more important for grazing (7.3 contacts/km). Human activities have resulted in a significant decrease in specific richness. Six endangered species were encountered, four belonging to the Accipitridae family. The greater bird diversity in the reserve compared to the periphery shows that protected areas are a long-term solution for biodiversity conservation.

Responses of birds to observers holding popguns:Hunting history infuences escape behavior of urban birds
2024年
Human activities affect bird behavior both directly and indirectly.Birds constantly regulate their behavior in response to human disturbance.Gun hunting,a major directional disturbance,puts enormous selection pressure on birds.In China,gun bans have been in place for nearly 30 years,and little hunting using guns occurs in modern cities.However,little attention has been paid to whether a history of hunting still affects the behavioral adaptations of urban birds.In this study,we compared the flight initiation distance(FiD)of the Eurasian tree sparrow Passer montanus,Azure-winged magpie Cyanopica cyanus,Common hoopoe Upupa epops and Eurasian magpie Pica pica in the presence of observers with or without popguns.The Eurasian tree sparrow,Azure-winged magpie,and Eurasian magpie effectively recognized the difference between the observers,and perceived the armed observer as a greater threat,exhibiting earlier escape behavior,but this phenomenon was not found in the Common hoopoe.The different expressions in FID of experimental bird species in China cities may be affected by the different levels of recognition of huntingpressuredue todifferent hunting histories.

Integrity and Size of Green Spaces Are Critical for the Functional Di-versity of Birds:Evidence from the Eastern and Northwestern Regions of China
2024年
Urbanization often changes bird species richness and affects the functional diversity.Therefore,understanding these changes helps city planners improve green space design and land use planning.Our study used multiple datasets to explore the effects of land-scape patterns and natural environments on the functional diversity of birds in urban parks and campuses in the eastern and northwest-ern regions of China.Firstly,we used the data to calculate birds of the functional richness(FRic),functional evenness(FEve),and functional divergence(FDiv)of 68 urban spaces in the eastern and northwestern regions of China.Further,we established generalized linear models of natural factors,human factors,and functional diversity.Results showed more bird species with unique traits were in the north-western region.This may be because the earlier urbanization in the eastern region filtered out urban-sensitive species,leaving behind urban adapters.Moreover,we found that the fractal dimension index was the most significant positive factor of FRic in the eastern region but the most significant negative factor of FDiv.Elevation was the most significant negative influence factor of FEve in the eastern region,but it was the most potent positive influence factor of FRic in the northwestern region.Population density had a significant positive effect on FDiv in the northwestern region.However,green space areas significantly negatively impacted FEve in the northwestern region.In addition,birds in parks in both regions had more functional traits than those on campuses,possibly because of the larger green space in parks,which may contain more fragments of native vegetation and reduce human interference.Our study suggests that preserving more original vegetation and reducing human disturbance in cities can increase the functional diversity of urban birds and im-prove urban ecosystem functions.

野生鸟类经济价值评估——以海南新盈红树林国家湿地公园鸟类为例
2024年
开展生物多样性尤其是野生鸟类经济价值评估是一项非常有意义而又难度较高的工作。本研究基于2017年颁布的《野生动物及其制品价值评估方法》中提供的相关鸟类基准价及其整体价值估算方法,利用文献提供的鸟类现场调查数据,并根据其最新的保护级别和濒危等级,对其基准价进行调整优化,量化了海南新盈红树林国家湿地公园2016年春、夏、秋、冬四季调查所发现鸟类的经济价值,结果发现:2016年春、夏、秋、冬4个季节调查发现的鸟类估值分别为144.28万元、13.00万元、1 043.82万元和1 044.99万元(2017年价),各季节间表现出较大差异。新盈红树林国家湿地公园对鸟类的承载作用冬季最大,秋季次之,夏季最小。从不同鸟类价值贡献看,重点应关注的鸟类为勺嘴鹬和黑脸琵鹭2种国家一级保护动物,其次是白鹭、大白鹭、中杓鹬和蒙古沙鸻等数量较多的鸟类。本研究提出的估值方法和传统生物多样性评估联合使用可更好了解调查区鸟类保护价值及其变化。

基于《野生动物及其制品价值评估方法》的湿地鸟类经济价值评估: 以江苏3片典型潮间带湿地鸟类为例
2024年
开展生物多样性尤其是野生鸟类经济价值评估是一项非常有意义而又难度较高的工作。本文基于2017年颁布的《野生动物及其制品价值评估方法》中提供的相关鸟类基准价及其整体价值估算方法,利用文献提供的鸟类现场调查数据,并根据其最新的保护级别和濒危等级,对其基准价进行调整优化,量化了江苏省南部滨海3片典型潮间带湿地2014年和2015年春秋两季珍稀濒危和其他重要鸟类的经济价值,结果发现:条子泥湿地鸟类2014年和2015年春秋两季估值分别为1.173×10^(8)元、5.682×10^(8)元和1.235×10^(8)元、3.938×10^(8)元(2017年价);洋口港2014年和2015年春秋两季估值分别为0.378×10^(8)元、1.041×10^(8)元和0.486×10^(8)元、0.788×10^(8)元;东凌港区域2014年和2015年春秋两季估值分别为0.584×10^(8)元、1.839×10^(8)元和0.472×10^(8)元、2.053×10^(8)元。从3片湿地鸟类经济估值结果看,条子泥是最重要的湿地;从不同野生鸟类经济价值大小和濒危程度综合看,勺嘴鹬、黑嘴鸥、小青脚鹬、白腰杓鹬和大滨鹬是3片调查区域最为重要的前5种鸟类。

从《中国鸟类分类与分布名录》看中国鸟类高级分类阶元的变迁——纪念郑光美院士逝世一周年
2024年
鸟类分类从传统的依据形态和解剖结构特征的Peters系统转换到以DNA分子为基础,从亲缘关系和演化时间推断的现代分类系统,各级阶元均发生了很大的变化。自2005年以来,郑光美院士主编出版了《中国鸟类分类与分布名录》第一至第四版,不仅报导了我国鸟类的物种及其分布,而且在分类体系上及时反映了鸟类分类系统的这种转变。本文基于4个版本的《中国鸟类分类与分布名录》,通过对比分析了我国鸟类目级阶元和科级阶元的变化及其原由。结果发现:第二版与第一版之间变化较小、第四版与第三版间变化也较小,主要变化发生在从第二版过渡到第三版;在目级阶元上,第三版比第二版新增加了4个目,即:鹲形目(PHAETHONTIFORMES)、鸨形目(OTIDIFORMES)、鲣鸟目(SULIFORMES)和隼形目(FALCONIFORMES),与此同时减少了雨燕目(APODIFORMES)和戴胜目(UPUPIFORMES)2个目;在科级阶元上,第三版新增加了14个科,减少了6个科。郑光美院士的系列著作为21世纪我国鸟类系统分类学奠定了基础,其博采众长、与时俱进的治学精神值得我们学习。作者谨以此文纪念郑光美院士逝世一周年。

江苏盐城湿地珍禽国家级自然保护区修复区越冬水鸟群落组成及栖息地利用
2024年
江苏盐城湿地珍禽国家级自然保护区是东亚—澳大利西亚迁徙路线上候鸟的重要停歇地和越冬地。于2022年11月至2023年2月(候鸟的越冬期),在该保护区的实验区的修复湿地中,对越冬水鸟资源进行持续监测,获取该区域越冬水鸟数量、群落组成等基础数据,并分析越冬水鸟的栖息地利用情况。研究结果表明,监测期间,共记录到水鸟36种,隶属于7目12科,累计数量23019只;其中,国家一级保护动物有4种,国家二级保护动物有3种;记录到IUCN濒危物种红色名录所列全球濒危(EN)物种东方白鹳(Ciconia boyciana),全球易危(VU)物种有3种,全球近危(NT)物种有2种;赤膀鸭(Mareca strepera)、绿头鸭(Anas platyrhyncho)、斑嘴鸭(Anas zonorhyncha)和白骨顶(Fulica atra)为修复区优势物种;修复区水鸟栖息地包括裸地、浅水区、深水区、芦苇(Phragmites australis)收割区、菖蒲(Acorus calamus)收割区和塘埂。不同栖息地中的水鸟数量和组成存在差异,在深水区中累计记录到的水鸟物种数(19种)和个体数量(18372只)都最多,其水鸟群落与裸地、芦苇收割区、菖蒲收割区、塘埂的水鸟群落的相似性指数都较低,浅水区的水鸟群落的物种多样性指数最大;积极开展水鸟监测、及时了解水鸟对栖息地利用的现状、关注修复湿地状况及其变化、针对栖息地水鸟资源的生态需求差异、维持修复区湿地内栖息地类型的多样性是提升保护区湿地及其水鸟资源管理能力的重要措施。
