| 1 | 松嫩平原苍鹭秋季栖息地选择及适宜性分布显示文摘苍鹭(Ardea cinerea)是松嫩平原湿地的常见鸟种,松嫩平原也是苍鹭重要的栖息地。为了了解苍鹭潜在栖息地的适宜性分布,利用GPS/GSM卫星跟踪技术,结合遥感影像和地理信息系统,应用Maxent模型对松嫩平原苍鹭秋季潜在的栖息地进行了评价,并对其适宜性分布进行了分析。结果显示:水源距离和绿度指数是影响松嫩平原苍鹭秋季栖息地适宜性的重要环境变量;松嫩平原内苍鹭适宜栖息地面积为2761.06 km^(2)(占研究区域的1.24%),主要分布在大庆(756.86 km^(2),占适宜栖息地面积的27.41%)、白城(537.14 km^(2),占适宜栖息地面积的19.45%)、齐齐哈尔(439.43 km^(2),占适宜栖息地面积的15.92%)等地市行政区,以大庆市杜尔伯特蒙古族自治县(429.90 km^(2),占适宜栖息地面积的15.57%)、白城市镇赉县(334.92 km^(2),占适宜栖息地面积的12.13%)、大庆市肇源县(185.54 km^(2),占适宜栖息地面积的6.72%)等县级行政区为主;其中,15.79%的适宜栖息地依次受到莫莫格保护区(10.34%)、扎龙保护区(3.47%)、向海保护区(0.67%)、查干湖保护区(0.54%)、大布苏保护区(0.41%)、乌裕尔河保护区(0.36%)等国家级自然保护区的保护。建议对未受到保护的零星小面积栖息地给与更多关注。 | 孙雪莹 李祎斌 吴庆明 徐卓 高晓冬 李玉春 柳旭 邹红菲 李晓民 | 2021 | 生态学报2021，41，7： | 7 |
| 2 | 动物移动网络研究对景观生态学的贡献显示文摘景观生态学在其发展之初的20世纪80年代,提出了关于景观网络研究(包括景观网络概念、网络结构指数和景观连接度)的基本构想,这些构想需要在景观过程的研究中逐渐被落实和发展。动物移动过程因动物在斑块或廊道上有着独特丰富的属性特征、与周围资源环境之间存在复杂反馈而区别于无机物运移的景观过程,则动物移动网络研究在实现关于景观网络研究的基本构想、推动景观生态学发展中贡献独特。因此,总结动物移动网络研究的来源脉络及其对景观生态学的理论贡献对于景观网络领域和景观生态学学科的发展都具有重要意义。本文抓住景观生态学发展之初提出的关于景观网络研究的基本构想,寻找和剖析其中所蕴含的景观生态学思想,追踪这些思想如何被落实、发展、并形成目前的三个热点方向:动物移动网络模拟、重要值评价和景观连接度分析;总结这三个方向的研究进展,指出整合动物的空间行为特征是必然发展趋势;揭示出动物移动网络研究始终都以发掘斑块或廊道的动物有机体的属性特征(如种群数量)、以及描述这种属性在不同斑块或廊道之间的差异和联系为方向,正是这种属性的发掘有效地落实、发展和丰富了关于景观网络研究的最初构想,对景观生态学的贡献比其他过程更为独特。文章还总结了我国动物移动网络研究与国际研究相比较为滞后的现状,指出其暂时尚未显示出对我国景观生态学的独特贡献;强调发展源于跟踪定位数据的动物空间行为生态学研究是减小差距的重要、必要前提。期望本文能引发关于景观网络乃至景观生态学理论发展的方向性思考,为研究者提供参考。 | 李月辉 胡远满 | 2021 | 生物多样性2021，29，1： | 3 |
| 3 | Contrasting habitat use and conservation status of Chinese-wintering and other Eurasian Greater White-fronted Goose(Anser albifrons)populations显示文摘Background:GPS/GSM tracking data were used to contrast use of(i)habitats and(ii)protected areas between three Arctic-nesting Greater White-fronted Geese(Anser albifrons,GWFG)populations throughout the annual cycle.We wished to demonstrate that the East Asian Continental Population(which winters on natural wetlands in the Chinese Yangtze River floodplain and is currently declining)avoids using farmland at multiple wintering sites.We also gath-ered tracking evidence to support general observations from two increasing population of GWFG,the North Sea-Baltic(which winters in Europe)and the West Pacific(which winter in Korea and Japan)winter mostly within farmland landscapes,using wetlands only for safe night roosts.Methods:We tracked 156 GWFG throughout their annual cycle using GPS/GSM transmitters from these three popu-lations to determine migration routes and stopover staging patterns.We used Brownian Bridge Movement Models to generate summer,winter and migration stopover home ranges which we then overlaid in GIS with land cover and protected area boundary at national level to determine habitat use and degree of protection from nature conserva-tion designated areas.Results:Data confirmed that 73%of European wintering GWFG homes ranges were from within farmland,com-pared to 59%in Japan and Korea,but just 5%in China,confirming the heavy winter use of agricultural landscapes by GWFG away from China,and avoidance of farmland at multiple sites within the Yangtze River floodplain.The same GWFG used farmland in northeast China in spring and autumn,confirming their experience of exploiting such habi-tats at other stages of their annual cycle.Chinese wintering birds showed the greatest overlap with protected areas of all three populations,showing current levels of site safeguard are failing to protect this population.Conclusions:Results confirm the need for strategic planning to protect the East Asian Continental GWFG popu-lation.While the site protection network in place to protect the species seems adequate,it has failed to stop the declines.Buffalo grazing could serve as one simple strategy to improve the condition of feeding habitats at Dongting Lake and Poyang Lake in the Yangtze,where vast Carex meadows exist.In addition,while we warn against pushing GWFG to winter farmland feeding in China because of the long-term potential to conflict with agricultural interests,we recommend experimental sacrificial,disturbance-free farmland within designated refuge areas adjacent to the Yangtze River floodplain wetland reserves as a manipulative experiment to improve the conservation status of this population in years when natural food sources are limited. | Xueqin Deng Qingshan Zhao Junjian Zhang Andrea Kölzsch Diana Solovyeva Inga Bysykatova-Harmey Zhenggang Xu Helmut Kruckenberg Lei Cao Anthony David Fox | 2021 | Avian Research2021，12，4： | 1 |
| 4 | Organising a juvenile ratio monitoring programme for 10 key waterbird species in the Yangtze River floodplain:analysis and proposals显示文摘Background:In the face of continued degradation and loss of wetlands in the Yangtze River floodplain(YRF),there is an urgent need to monitor the abundance and distribution of wintering waterbirds.To understand fully observed annual changes,we need to monitor demographic rates to understand factors affecting global population size.Annual reproduction success contributes to dynamic changes in population size and age structure,so an assessment of the juvenile ratio(i.e.first winter birds as a proportion of total number aged)of overwintering waterbirds can be an important indicator of the reproductive success in the preceding breeding season.Methods:During 2016-2019,we sampled juvenile ratios among 10 key waterbird species from the wetlands in the YRF.Based on these data,we here attempt to establish a simple,efficient,focused and reliable juvenile ratio monitoring scheme,to assess consistently and accurately relative annual breeding success and its contribution to the age structure among these waterbird species.Results:We compared juvenile ratio data collected throughout the winter and found that the optimal time for undertaking these samples was in the early stages of arrival for migratory waterbirds reaching their wintering area(early to mid-December).We recommend counting consistently at key points(i.e.those where>1%biogeographical flyway population were counted)at sites of major flyway importance(Poyang Lake,East Dongting Lake,Shengjin Lake,Caizi Lake,Longgan Lake and Chen Lake).Based on this,the error rate of the programme(155 planned points,the count of 10 waterbird species is 826-8955)is less than 5%.Conclusions:We established a juvenile ratio monitoring programme for 10 key waterbird species in the wetlands of the YRF,and discuss the feasibility and necessity of implementing such a future programme,and how to use these data in our monitoring and understanding of the population dynamics of these waterbird populations. | Yuxi Wang Iderbat Damba Qingshan Zhao Yanbo Xie Xueqing Deng Rdi Ga Guanhua Liu Zhiwen Xu Yue Li Dali Gao Wenbin Xu Guoxun Chen Lei Cao | 2021 | Avian Research2021，12，4： | 1 |
| 5 | 滦河上游——白枕鹤西部种群的重要停歇地显示文摘白枕鹤(Grus vipio)为国家Ⅱ级重点保护野生动物,被IUCN列为易危(VU)物种。白枕鹤西部种群繁殖于中蒙俄交界处的达乌尔地区,数量呈下降趋势。我们于2017–2018年在蒙古国东部给白枕鹤西部种群的50只个体佩戴了GPS-GSM跟踪设备。截至2019年5月,获得春季和秋季迁徙路径各48条。分析结果显示:春季91.67%和秋季72.91%的跟踪个体在滦河上游(河北省沽源–内蒙古正蓝旗–多伦区域)停歇,春季停留时间36.16±15.00天、秋季20.26±11.08天,分别占春季和秋季迁徙时间的75%和67%,确定了这一区域是西部种群迁徙途中最重要的停歇地。迁徙路线栖息地选择模型结果显示,白枕鹤常在距离湖泊较近(<210 km)、海拔1,200–1,500 m,且坡度小(<1°)的区域停歇。而滦河上游和整条迁徙路线停歇位点比较的模型结果显示,滦河上游停歇地的海拔1,200–1,500 m与整条迁徙路线栖息地选择模型的结果一致;此外这个区域离河流更近(<70km),不仅有湿地和水体的栖息环境,还有草地和农田可供觅食和栖息。保护空缺分析发现滦河上游现有四处保护地,但在保护地内的迁徙停歇点不超过总位点的1.63%。综上,我们建议将滦河上游整体纳入保护地体系进行管理,为这一受胁物种及其栖息地管理和保护提供可靠保障。 | 郎雪敏 Gankhuyag Purev-Ochir Oyunchimeg Terbish Dashdorj Khurelbaatar Baasansuren Erdenechimeg Amarkhuu Gungaa 宓春荣 郭玉民 | 2020 | 生物多样性2020，28，10： | 1 |
| 6 | Seasonal and regional differences in migration patterns and conservation status of Swan Geese(Anser cygnoides)in the East Asian Flyway显示文摘Background:The Swan Goose(Anser cygnoides)breeds across Mongolia and adjacent China and Russia and winters exclusively in China.It is globally threatened,showing long-term major range contractions and declining abundance,linked to habitat loss and degradation.We remain ignorant about the biogeographical subpopulation structure of the species and potential differences in their migration timing,stopovers and schedules,information that could be vital to effective conservation of different elements of the species population,which we address here with results from a telemetry study.Methods:In 2017-2018,we attached GPS/GSM telemetry devices to 238 Swan Geese on moulting sites in three discrete parts of their summering area(Dauria International Protected Area,Central Mongolia and Western Mongolia),generating 104 complete spring and autumn migration episodes to compare migration speed and nature between birds of different summer provenances.Results:Birds from all three breeding areas used almost completely separate migration routes to winter sympatrically in the Yangtze River floodplain.Although many features of the spring and autumn migrations of the three groups were similar,despite the significantly longer migration routes taken by Western Mongolian tagged birds,birds from Dauria Region arrived significantly later in winter due to prolonged staging in coastal areas and took longer to reach their breeding areas in spring.Among birds of all breeding provenances,spring migration was approximately twice as fast as autumn migration.Areas used by staging Swan Geese(mainly wetlands)in autumn and spring almost never fell within national level protected areas,suggesting major site safeguard is necessary to protect these critical areas.Conclusions:This study showed the discreteness of migration routes taken by birds of different summer provenances and differences in their migratory patterns,highlighting key staging areas(Yalu River Estuary in China/North Korea for Dauria Region breeding birds,Daihai Lake for Central Mongolian and Ordos Basin for Western Mongolian birds).Based on this new knowledge of the biogeographical subpopulation structure of the Swan Goose,we need to combine data on subpopulation size,their distribution throughout the annual life cycle and conservation status,to develop more effective conservation strategies and measures to reverse population decline throughout the range. | Iderbat Damba Junjian Zhang Kunpeng Yi Huashan Dou Nyambayar Batbayar Tseveenmyadag Natsagdorj Batmunkh Davaasuren Lei Cao Anthony David Fox | 2021 | Avian Research2021，12，4： | 0 |
| 7 | 河南民权湿地公园青头潜鸭越冬栖息地适宜性评价显示文摘为了累积青头潜鸭栖息地适宜性方面的保护生物学信息,并为后续的迁地保护饲养繁育提供野外理论基础,基于最大熵(Maxent)模型,对河南民权黄河故道国家湿地公园青头潜鸭的越冬栖息地适宜性进行了分析与评价.结果表明:民权湿地公园内青头潜鸭适宜的越冬栖息地面积较小,仅占该区域总面积的4.66%,多集中于废弃鱼、藕塘等隐蔽性较好、食物较充足的小生境水域.应通过合理设置禁渔期、设立禁渔区、减少或杜绝人为干扰等,加强对该区域青头潜鸭的保护管理工作. | 孙雪莹 张琦 吴庆明 徐卓 邓文攸 NGO Thi kieu trang 徐炯 安凯滨 | 2023 | 东北师大学报(自然科学版)2023，55，3： | 0 |
| 8 | Differing migration patterns and year-round habitat-use of allopatric nesting Eastern Tundra Bean Geese(Anser fabalis serrirostris)in East Asia显示文摘Sympatric Chinese-wintering Eastern Tundra Bean Geese(Anser fabalis serrirostris,ETBG)breed in two widely separated Arctic areas(Central Russian Arctic and Anadyr region);South Korean-wintering birds(Chaun-South Korea)breed in a third discrete area between these two.Such winter/summer segregation likely structures the population,potentially resulting in distinct migration patterns and habitat-use throughout the annual cycle.We tracked individuals using GPS-GSM transmitters from all three of these geographically discrete ETBG subpopulations to see whether this was the case,testing for differences in migration patterns,seasonal and diurnal habitat-use using remotely sensed land-cover mapping.Mean migration distance of Central Arctic-China and Chaun-South Korea individuals did not differ significantly,but Anadyr-China birds travelled 15–24%further(mean:1140 km,P<0.001).Despite this,mean spring migration durations were longest among Central ArcticChina ETBG,significantly longer than Anadyr-China geese,due to significantly longer stopovers,which were significantly longer than Chaun-South Korea birds.Autumn migration duration of Central Arctic-China and Chaun-South Korea individuals was significantly shorter than in spring,with fewer,shorter stopovers.Lack of significant differences in migration and stopover duration or numbers of stopovers between spring and autumn among Anadyr-China ETBG confirms this is a plastic trait,differing between subpopulations responding to prevailing conditions.Migration patterns and habitat-use differed significantly between all three ETBG subpopulations,although all tended to use wetlands more at night and croplands more in daytime in winter,suggesting specific adaptations and responses to differing conditions encountered along their different migration routes.Although untestable,we speculate that differences in habitat-use may affect fitness levels and genetic exchange between subpopulations,but based on our observations,conclude clear differences in migration and foraging ecology between these elements of the same subspecies,even in winter sympatry. | Fanjuan Meng Jing Zhang Chang Li Qingshan Zhao Diana Solovyeva Hansoo Lee Liding Chen Lei Cao Anthony David Fox | 2022 | Avian Research2022，13，4： | 0 |
| 9 | Autumn migration routes of fledgling Chinese Egrets(Egretta eulophotes)in Northeast China and their implications for conservation显示文摘The Chinese Egret(Egretta eulophotes)is a globally threatened bird species living on the coast and islands of Liaoning,northeastern China,mainly in summer.To further protect the breeding population of Chinese Egrets,it is important to understand the current protection status of their distribution sites at pre-migration period and migration routes.Thirty-three individuals were tagged with satellite transmitters at Fantuo Island in Changhai and Xingren Island in Zhuanghe,Liaoning Province,northeastern China,in July of 2016,2017,and 2018,to identify important distribution sites during the pre-migration period,as well as detailed migration routes.The results showed that coastal mudflats in Liaoning and the west coast of North Korea were important feeding and roosting sites for fledgling Chinese Egrets from August to September.The home range sizes in August were significantly larger than in September.The eastern coast from Shandong to Guangdong,as well as Taiwan,China,and Manila Bay and Galileo Islands in the Philippines,were important stopover sites during fall migration.Specifically,we found that the egrets’autumn migration could be divided into four routes,i.e.,sea-crossing migration(SCM),coastal migration(CM),inland migration(IM),and mixed migration(MM).The migration distance,timing,speed,and straightness of the four routes also differed.The SCM routes were the straightest,and had the fastest migration speed and shortest travel time,while the IM routes had the lowest straightness and speed,and the longest duration.Manila Bay and Bohol Island in the Philippines,the west coast of Tanintharyi in Myanmar,and the Zengwun River Estuary in Taiwan,China,were wintering sites.Our findings on the key distribution sites along pre-migration and fall migration routes,including some stopover sites,have important implications for the conservation of and global action plan development for the vulnerable Chinese Egret. | Hongying Xu Zeyu Yang Dongping Liu Ru Jia Lixia Chen Boshi Liang Zhengwang Zhang Guogang Zhang | 2022 | Avian Research2022，13，1： | 0 |
