Benefits of protected areas for nonbreeding waterbirds adjusting their distributions under climate warming. [PDF]
Abstract Climate warming is driving changes in species distributions and community composition. Many species have a so‐called climatic debt, that is, shifts in range lag behind shifts in temperature isoclines. Inside protected areas (PAs), community changes in response to climate warming can be facilitated by greater colonization rates by warm‐dwelling

Finding floral and faunal species richness optima among active fire regimes. [PDF]
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Effects of forest fragmentation on avian breeding activity
Abstract Biodiversity declines and ecosystem decay follow forest fragmentation; initially, abundant species may become rare or be extirpated. Underlying mechanisms behind delayed extirpation of certain species following forest fragmentation are unknown.

Oaks are often removed as part of longleaf pine restoration; however, it is unclear if oak patches produce important resources for native wildlife. We studied wildlife use of the transition between longleaf pine woodlands and hardwood hammocks. We found these areas support a variety of wildlife species and future management and restoration of longleaf ...

The rainforests of Southeast Asia have a high diversity of animals, many of which eat fruit and disperse the seeds of forest plants. Several large‐bodied species occur in these forests; these animals are predicted to have especially important seed dispersal roles but are also among the species most threatened by defaunation.

Lessons from seabird conservation in Alaskan longline fisheries
Abstract Although bycatch of seabirds and other long‐lived species is a critical conservation issue in world fisheries, case studies documenting significant reductions in the mortality of these low‐productivity species in a fishery are rare. We studied progress toward seabird conservation in the Alaskan longline fisheries, one of the largest and most ...

园林鸟类是城市环境质量的重要指标,也是城市自然保护和生态建设的重要组成部分.1997年10月至1998年12月,通过选取杭州市区20个主要园林,根据季节每月一至两次调查园林鸟类的物种和数量,对杭州市园林鸟类的群落结构及其季节变化进行了分析探讨,结果显示:全部园林中共记录到鸟类82种,其中迁徙鸟类50种,占61%,留鸟32种,占39% ;园林鸟类群落呈现出较强的季节性,从全部园林总体上看,物种数和总数量呈现春秋两个高峰,夏季最低;从单个园林来看,多数园林鸟类群落物种数的最高峰集中在冬季 ...

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 ...

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 ...

城市森林公园是繁殖季节鸟类的重要栖息地,研究鸟类群落的变化规律,能为鸟类保护和公园的规划管理提供科学的依据。2014—2018年,采用固定样线法对南京老山国家森林公园繁殖期鸟类组成及年间变化进行了研究,共记录鸟类90种,隶属10目34科,以留鸟(55.6%)和夏候鸟(32.2%)为主,其中国家Ⅱ级重点保护鸟类8种。从月份变化上看,5月和6月繁殖季鸟类种数和密度无显著性差异;从年间变化上看,5年间鸟类物种数在46—68种之间波动,数量在752—1063只之间波动;鸟类群落多样性指数年间变化为3.268—3.
