北京市区流浪猫密度的初步抽样调查

open access: yes野生动物学报, 2007
城市中日益增多的流浪宠物正在成为一个困扰人们的问题。2006年3月至2006年5月,我们开展了北京市流浪猫的抽样调查,总计随机调查52个地点。这些调查地点分布于北京市五环内,一般每个调查地点调查1个样点,有4个地点调查了2个调查样点。调查样点以居民区为主。通过询问、样线调查等方式,获得了样点内流浪猫数量、繁殖情况和喂饲状况等数据。

Study on coordinated development of environmental quality and land use degree based on remote sensing ecological index: A case study of Zhejiang province(基于遥感生态指数的土地利用程度与环境质量协调发展研究——以浙江省为例)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
将遥感生态指数应用于土地利用程度与生态环境质量协调研究,结合耦合协调度模型和空间自相关分析,研究了2008,2013,2018年浙江省89个区县的土地利用程度与生态环境质量协调发展时空特征,结果表明:(1)在空间尺度上,浙江省土地利用程度呈东高西低、北高南低的分布态势,各区县发展差距较大。在时间尺度上,各区县土地利用程度均有不同程度的提高,东高西低的趋势越发显著。(2)浙江省由于自然地理条件优越,生态环境质量总体保持较高水平,十年来生态文明建设取得了较大成果。(3)结合土地利用程度与生态环境质量评价结果,

Data currency evaluation method of the second national land survey(第二次全国土地调查成果现势性评估方法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2016
第二次全国土地调查(以下简称二次调查)成果的现势性是评价二次调查成果质量的重要指标之一.针对现势性评估理论模型缺乏的现状,提出了利用建设用地现势性指数和建设用地占用耕地变更正确性指数来评估二次调查成果的现势性.并对杭州市9区(县)的二次调查成果进行了现势性评估,结果表明,该方法科学可靠,适用于评估二次调查成果的现势性.

Winter Track Survey of the Amur Tiger (Panthera tigris altaica) in the Southwest Primorsky Province of Russia 俄罗斯滨海边疆区西南部东北虎 (Panthera tigris altaica) 冬季足迹调查

open access: yesWildlife Letters, EarlyView.
In the winter of 2021/2022, a winter track survey revealed 43–46 tigers (without cubs) in 5.4 thousand km2 of suitable habitats in the Southwest Primorsky Province of Russia. In the same period, a network of camera traps registered 54 adult/subadult tigers here.

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

open access: yesWildlife Letters, EarlyView.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

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

Inferring alternative ecosystem states with field survey data

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

open access: yesConservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, EarlyView.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate
