上海市野生动物栖息地修复成效评价体系建立及应用

open access: yes野生动物学报, 2023
建设野生动物栖息地是应对城市化进程中野生动物及其生存环境逐渐消失、破碎化的关键手段,开展野生动物栖息地修复成效评价可以为后期维护管理提供科学支撑,是提升栖息地修复质量的有效机制。根据上海野生动物栖息地的特点,针对湿地、鸟类、蛙类和獐(Hydropotes inermis)4个典型修复类型,从修复目标、栖息地环境、生物质量和管护水平4个方面提出11个评价指标,基于层次分析法和专家评判法设置评价标准及分级体系,进行修复成效评价。研究表明:(1 ...

Vegetation characteristics of habitats used by Elliot's pheasant(白颈长尾雉栖息地的植被特征研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2001
构成白颈长尾雉阔叶林型栖息地的植被乔木层主要树种为壳斗科植物,灌木层植物以山茶科、禾本科和樟科等科的种类为主,草本层植物以蕨类、禾本科和莎草科为主.在针阔混交林型栖息地,壳斗科植物仍占乔木层主要树种的相当比例,但针叶树种的比例明显上升,该类型栖息地的灌木层和草本层植物组成特征与阔叶林型栖息地相似.在针叶林型栖息地中,乔木层的主要树种为马尾松、杉木、福建柏和圆柏等,并有较多的阔叶灌木树种构成灌木层,草本层中以蕨类为主.白颈长尾雉栖息地选择的最主要影响因素是乔木层盖度.

东北地区三种鹿科动物潜在栖息地预测与保护空缺分析

open access: yes野生动物学报, 2021
栖息地是野生动物赖以生存的根本,掌握物种潜在栖息地的空间分布及其与环境因子的关系可以加强对物种的保护。鹿科(Cervidae)动物是东北地区森林等生态系统不可或缺的一部分,本研究选取东北地区3种鹿科动物马鹿(Cervus elaphus)、梅花鹿(Cervus nippon)、驼鹿(Alces alces)为研究对象,通过查阅文献、全球生物多样性信息网络数据库(GBIF)以及部分外业数据得到物种分布点,运用MaxEnt软件对3种鹿科动物进行潜在栖息地预测,模型AUC值如下:马鹿0939,梅花鹿0 ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

open access: yesWildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Context‐Dependent Effects of Beavers (Castor spp.) on Freshwater Pearl Mussels (Margaritifera margaritifera) in European Rivers 河狸对欧洲河流中的淡水珍珠贝 (Margaritifera margaritifera) 存在情境依赖性影响

open access: yesWildlife Letters, EarlyView.
The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

Studies on the factors affecting patch use degree by Elliot's pheasant(白颈长尾雉栖息地小区利用度影响因子研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2002
1995年10月至1996年5月在浙江省开化县水坞山区采用无线电遥测技术和样方法对白颈长尾雉栖息地小区利用度影响因子进行研究,结果显示:(1)食物和水因子是决定白颈长尾雉栖息地利用度的最主要因子,随季节的变化,影响白颈长尾雉栖息地小区利用度的食物种类亦随之变化.(2)冬季,灌木层因子的作用大于草本层因子;春季,草本层因子的作用大于灌木层因子.(3)白颈长尾雉栖息地小区利用度多元回归模型:冬季: Y=0.044 438X1+0.003 519X2-0.001 542X3+0.074 533;冬末春初:Y ...

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

The collective application of shorebird tracking data to conservation

open access: yesConservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership
