How much biotic nativeness matters across human demographic groups. [PDF]
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

湿地鸟类不仅是鸟类的重要组成部分,也是湿地环境质量变化的重要指示物种。根据陕西安康瀛湖湿地保护区湿地生境状况,将研究区划分为河流湿地、水库湿地、沼泽和草甸湿地3种类型,于2016年9月—2019年8月,采用样线法与样点法对瀛湖湿地保护区水鸟群落特征和多样性进行调查,共记录到湿地水鸟68种,隶属8目17科,其中,旅鸟25种,冬候鸟20种,夏候鸟13种,留鸟9种,迷鸟1种;国家一级保护水鸟2种,国家二级保护水鸟5种,省级重点保护水鸟12种,“三有”水鸟43种;广性分布水鸟11种,中性分布水鸟23种 ...

剑湖是云贵高原重要的水鸟越冬地,掌握其冬季水鸟群落特征对水鸟保护以及湿地资源管理具有重要指导意义。于2017年和2018年冬季采用样点法对剑湖进行了水鸟多样性调查。共记录到水鸟6目9科36种,种类组成上以雁形目鸭科鸟类为主(16种),但数量上以秧鸡科骨顶鸡(36.53%)和紫水鸡(17.09%)为优势。根据物种丰富度非参数估计,剑湖水鸟丰富度为42.80 ± 0.86。从居留类型上来看,剑湖水鸟以冬候鸟为主,占总记录种数的72.22%。对比两冬季数据发现剑湖水鸟多样性存在显著的年际变化 ...

2016年9月—2019年3月,采用样点法在水鸟的南迁期(8—10月)、越冬期(11月—次年1月)、北迁期(2—3月)对云南省泸沽湖省级自然保护区迁徙水鸟进行监测。共记录水鸟7目10科38种,其中有国家二级重点保护野生鸟类3种、云南省省级重点保护野生鸟类1种。研究期内,保护区内越冬水鸟优势种累计记录10种,分别为赤麻鸭(Tadorna ferruginea)、绿头鸭(Anas platyrhynchos)、赤颈鸭(Mareca penelope)、罗纹鸭(M.falcata)、赤膀鸭(M ...

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

Effects of restoration practices on biodiversity in temperate and boreal forests
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

A link between increased temperature and avian body condition in a logged tropical forest
Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.
