Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Abstract The IUCN (International Union for Conservation of Nature) Red List categories and criteria are the most widely used framework for assessing the relative extinction risk of species. The criteria are based on quantitative thresholds relating to the size, trends, and structure of species’ distributions and populations.

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

The edge densities of cropland, developed land, and water bodies (panel a) predict the spatial probability of mammalian predation on wild turkeys (panel b) using Mahalanobis distance factor analysis in Quitman County, Mississippi, United States. The three habitat fragmentation variables are represented by three arrows, respectively.

Long‐Distance Corridors Facilitate Asian Elephant Adaptation to Climate Change 长距离廊道有助于亚洲象适应气候变化
Climate change presents significant challenges for Asian elephants, forcing them to either remain in degraded habitats or seek new ones. But, remaining would lead to resource shortages, while moving is hindered by movement barriers. This study integrates species distribution models (MaxEnt) and the minimum cumulative resistance (MCR) model to construct

Knowledge of the reproductive success of organisms in urban habitat fragments is needed to conserve biodiversity in our urbanizing world. We found that differences in nest success among birds in urban forest patches is explained by factors on three distinct spatial scales even across a limited urban development gradient.

Abstract Tibetan Buddhist monasteries are widely distributed throughout the Qinghai–Tibet Plateau and are significant locations for human–wildlife coexistence. Given the significance of their historical and contemporary social influence, it is crucial to ascertain whether there exists a non‐negligible correlation between these monasteries and their ...

景观连接度度量了物种在斑块之间的运动不受阻碍的连通性,对生境质量和破碎化研究有重要意义。本文基于2004年和2013年扎龙自然保护区遥感影像的解译分类,采用基于图论法的面积权重指数(AWF)划定巢址景观连接度等级,然后对不同景观连接度区域的景观格局特征指数进行分析。结果显示:2004年高景观连接度的丹顶鹤生境斑块面积为522.16 km2,而2013年高景观连接度斑块下降为432.82 km2,高景观连接度斑块集中分布于核心区内部; 2013年高景观连接度斑块的平均斑块周长面积比明显高于其他斑块 ...

气候变暖是全球气候变化最主要的表现形式。由于人类活动的影响,全球气候变暖已成为不可逆转的趋势,严重影响物种的生存和繁衍。大熊猫作为世界珍稀濒危物种中的旗舰保护种,具有扩散、繁殖能力低、食物单一、分布范围窄、生境破碎化严重等特点,对气候变化较为敏感,气候变化极有可能成为大熊猫新的生存危机。因此,掌握气候变化形势、科学认识气候变化对大熊猫的影响,对大熊猫的保护工作有重要的理论和现实意义。文章总结了目前气候变化对大熊猫影响的研究进展,提出了一些存在的问题及建议。目前,关于气候变化对大熊猫影响的研究初有成果 ...
