蟒河国家级自然保护区华北豹栖息地选择

open access: yes, 2022
华北豹(Panthera pardus japonensis)作为我国特有的豹亚种,是华北地区森林生态系统中的顶级捕食者之一,在维持生态系统的结构稳定和功能发挥中起着不可或缺的生态作用,但目前国内外对于华北豹种群空间分布及其栖息地选择等基本生态学规律了解依然十分不足,严重限制了科学保护策略的制定。本研究基于自动相机监测数据,应用资源选择函数模型(RSFs)对山西阳城蟒河国家级自然保护区内的华北豹种群空间分布和栖息地选择进行了分析,探讨华北豹的潜在猎物、自然环境 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

open access: yesConservation Biology, EarlyView.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

open access: yesConservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Modeling seed germination data to meet biodiversity conservation needs in the Mediterranean

open access: yesConservation Biology, EarlyView.
Workflow to assess the availability and quality of germination data and assign species' thermal risk in the Mediterranean. (a) Assessment of data availability, including the phylogenetic distribution of the number of records (i.e. available germination data); (b) data quality assessment; and (c) assignment of climate risk categories for species that ...

基于红外相机监测的色达县赤狐适宜栖息地评价

open access: yes野生动物学报
赤狐(Vulpes vulpes)是国家二级重点保护野生动物,也是色达县棘球绦虫(Echinococcus)等恶性疾病的重要传播源,掌握该物种时空利用特征可促进其有效管护。2023年5月—2024年6月,利用红外相机监测四川省甘孜州色达县赤狐活动,并对其栖息地影响因子、适宜栖息地和日活动节律进行分析,结果显示:赤狐的日活动强度分布不均匀(α > 0.042),其在05:00、20:00和24:00出现活动峰值,在09:00—15:00活动较少,呈夜行性(β = 0.09);年均降水量、土地覆盖类型、

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau

open access: yesPeople and Nature, Volume 8, Issue 7, Page 2186-2199, July 2026.
Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

黄渤海斑海豹种群现状调查

open access: yes野生动物学报, 2008
2003~2007年,对斑海豹在渤海的繁殖区和辽东湾北部双台子河口、大连旅顺虎平岛及渤海海峡的庙岛群岛3个栖息地,分别进行了斑海豹种群数量调查,并对黄海北部韩国白翎岛斑海豹度夏栖息地进行了现场考察。调查结果表明:渤海3个栖息地斑海豹数量处于动态变化之中,空间分布格局虽未发生明显变化,但斑海豹种群数量有下降趋势。白翎岛栖息地斑海豹数量波动与渤海3个栖息地斑海豹数量密切相关。由于生态环境不断恶化,尤其近年偷猎现象增多,严重威胁着本种群的生存。为此,亟待加强对斑海豹资源的保护。

子午沙鼠的微栖息地选择特征及其对采食行为研究

open access: yes, 2010
选择吐鲁番盆地沙质荒漠区,以子午沙鼠为模型研究典型荒漠鼠种的微栖息地选择和取食对策。结合网格样方法和人工食物盘法通过对目标种采食点与灌木(高度在1m以上)的距离(≤1m,≤2m和>2m),采食点地形地貌(土质-沙质,谷地-沙丘)的分析确定目标种的微栖息地选择;通过目标种对食物盘的取食强度(放弃密度GUD)确定目标种的微栖息地选择偏好。结果显示,目标种对距灌木≤2m点和≤1m点的选择差异不显著,对于≤1m和>2m的点选择差异显著;对于≤2m点和>2m点的选择差异显著 ...
