Changes in the transformative potential of action proposals in Finnish Red Lists from 1986 to 2019

open access: yesConservation Biology, EarlyView.
Abstract Red lists provide critical knowledge regarding biodiversity decline, especially in Finland, where broad assessments have been made regularly since the 1980s. They deliver information on the threat status of species and ecosystems, propose actions to guide conservation policy, and have the potential to spur transformative change.

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 ...

厦门市春夏两季鸟类多样性研究

open access: yes野生动物学报, 2007
通过对代表厦门5种不同生境类型的8个样地进行鸟类调查,共记录到鸟类17目49科242种,占全国鸟类总种数的19.5%,占福建省鸟类总种数的44.7%。与全国鸟类组成相比,厦门鸣禽和涉禽的物种多样性相对比较丰富;比较5种代表性的生境鸟类多样性,农田物种多样性最丰富(Shannon-Wiener指数H′=5.549 63),但是其科属多样性却最低(G-F指数DFG=0.53568);森林生境中科属多样性最高(G-F指数D(FG)=0.872282),特别是科多样性显著高于其他生境(F指数DF=15.8911)

Twelve principles for successful governance of community‐based coastal marine restoration

open access: yesConservation Biology, EarlyView.
Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

Effects of restoration practices on biodiversity in temperate and boreal forests

open access: yesConservation Biology, EarlyView.
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.

利用红外相机调查四川卧龙国家级自然保护区鸟兽多样性

open access: yes, 2017
卧龙国家级自然保护区位于邛崃山脉东南坡,地处邛崃山自然保护区群的核心地带。2014–2016年,我们在卧龙保护区内使用红外相机技术开展大中型兽类与鸟类的本底调查。经过10,961个相机工作日的调查,完成有效调查位点83个,覆盖58个公里网格。共鉴定出分属6目15科的32种野生兽类和4种家畜,探测数总计2,095次,其中国家一、二级重点保护野生动物分别有5、11种,被IUCN红色名录评估为濒危(EN)、易危(VU)、近危(NT)的动物分别有4、6、4种。野生兽类中,食肉目物种数最多,共6科16种 ...

矿区侵蚀土壤的微生物活性及其群落功能多样性研究

open access: yesShuitu Baochi Xuebao, 2003
通过对浙江省天台铅锌银矿区侵蚀土壤的微生物活性以及微生物群落功能多样性研究,结果表明:人为开矿使矿区土壤环境呈现不同层次的加速侵蚀特征。矿区侵蚀土壤的几种重金属含量比无明显侵蚀土壤有明显的增加,且其基本理化性质相应变差。矿区侵蚀土壤微生物特征发生了显著的变化,与无明显侵蚀土壤相比,微生物生物量和可培养细菌数量显著降低,但土壤基础呼吸和微生物代谢商(qCO2)值却明显升高。Biolog测试结果显示,随着土壤侵蚀程度的加剧,其微生物群落结构亦发生了相应改变,侵蚀土壤微生物群落的丰富度、多样性指数 ...

威海市斑块冬季鸟类多样性与生境的关系

open access: yes野生动物学报, 2012
近年来,威海一直致力于生态城市的建设。物种多样性是生态城市的重要指标,而在物种多样性中,城市鸟类多样性起着重要的作用。本文调查了冬季威海7个斑块(2个校园和5个典型生活小区)的鸟类多样性,对其物种多样性指数以及均匀度指数进行分析,得出山东大学校园和哈尔滨工业大学校园的鸟类多样性高于5个小区斑块,而且2个校园斑块的均匀度在7个斑块中也处于较高水平。另外,结合实际情况,文章从绿化面积、城市栖息地的空间异质性、生境破碎化程度以及人为干扰4个方面对城市鸟类丰富度与多样性的影响因素做出讨论 ...

Assessing and strengthening community‐based coastal governance

open access: yesConservation Biology, EarlyView.
Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

遥感在生物多样性研究中的应用进展

open access: yes, 2018
随着人口的持续增长,人类经济活动对自然资源的利用强度不断升级以及全球气候变暖,全球物种正以前所未有的速度丧失,生物多样性成为了全球关注的热点问题。传统生物多样性研究以地面调查方法为主,重点关注物种或样地水平,但无法满足景观尺度、区域尺度以及全球尺度的生物多样性保护和评估需求。遥感作为获取生物多样性信息的另一种手段,近年来在生物多样性领域发展迅速,其覆盖广、序列性以及可重复性等特点使之在大尺度生物多样性监测和制图以及评估方面具有极大优势。本文主要通过文献收集整理,从观测手段、研究尺度 ...
