Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

野生动物学报, 2016 水位不仅直接关系着湿地的存在,更关系着湿地水鸟的栖息利用。关于湿地水鸟栖息水位的测量,一直是难以解决的关键问题。目前在科研中普遍采用相对水位测量,但多难以反映水鸟所在位置的真实水位和真实的科研成果。为了更为深入地掌握湿地水鸟栖息水位的真实数据,对鸟体形态指标法和水文水位法进行了方法步骤、优缺点等方面的详细介绍,并初步认为:鸟体形态指标法理论上更适合湿地水鸟栖息水位的测量,且是可行的,建议尝试使用鸟体形态指标法进行实践验证和推广。

Integrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

野生动物学报, 2008 红碱淖湿地位于中国候鸟迁徙的主要路线上,水鸟分布较为集中,是遗鸥、大天鹅等珍稀水鸟的重要迁徙停歇地和繁殖地。通过对红碱淖湿地遗鸥及水鸟的种群和分布进行了8 a的实地调查和研究,统计分析了红碱淖2001～2007年的遗鸥和水鸟的种群数量动态变化。研究结果表明2007年红碱淖湿地的遗鸥繁殖巢数达5 036巢,种群数量10 072只,已成为全球最大遗鸥种群,在此基础上,还总结了红碱淖湿地7目14科55种水鸟的分布和保护价值,为水鸟的保护和管理提供了依据,对红碱淖湿地遗鸥及水鸟的保护具有重要意义。

Integrative Conservation, Volume 5, Issue 1, Page 74-85, March 2026.This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

鄂尔多斯遗鸥国家级自然保护区湿地鸟类群落结构及其对水环境的响应
野生动物学报, 2022 2016—2019年对内蒙古鄂尔多斯遗鸥国家级自然保护区的鸟类物种多样性及群落结构进行了调查,同时对水质指标进行了年度监测。保护区共记录到鸟类51种,隶属于9目13科,其中夏候鸟23种,旅鸟24种,留鸟4种。在鸟类区系方面,古北界鸟种1种,广布种50种。湿地鸟类群落物种丰富度、多样性指数和均匀度指数均从2016年开始呈下降趋势,2018年开始回升,但未恢复到初始水平。水质指标测量结果显示,保护区水环境总体质量较差。虽然鸟类多样性和污染物综合指标变化相关性并不显著,但是从总体上看 ...

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...
