The impacts of habitat heterogeneity of mangroves on mollusks diversity at Dongzhaigang Bay, Hainan [PDF]
, 2016 包括软体动物在内的大型底栖动物是红树林生态系统的重要组成部分，几乎在所有的红树林生境类型中都能够发现它们的存在，其在红树林中占据了重要的生态位，通过穴居、取食等活动改变着红树林有机物循环的物理和化学过程，对红树林生态系统的结构和功能的维持具有非常重要的作用，是红树林生态系统中食物网的重要环节。本文选取了海南省东寨港国家级自然保护区内三个不同地点的红树林从空间尺度方面对其中的软体动物分布进行了研究。此外还比较了不同地点的红树植物群落内软体动物分布的特点。 选择了海南东寨港的湾口(塔市)、中部(后排 ...

Methods in Ecology and Evolution, EarlyView.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Shuitu Baochi Xuebao, 2022 为探讨物种多样性与地上生物量的相关性以及物种多样性的垂直变化特征。以阿尔泰山布尔津林区5种草地类型为研究对象, 通过对布尔津林区各草地类型的调查, 分析了阿尔泰山布尔津林区各草地类型的物种多样性变化特征。结果表明: (1)5个草地群落类型地上生物量差异明显, 荒漠草原和山地草甸草原较低, 山地草原最高, 而山地草甸和高寒草甸处于两者之间。(2)各草地类型群落间的物种多样性指数、优势度指数、丰富度指数和均匀度指数有明显差异, 高寒草甸的物种优势度、多样性和均匀度的情况最好 ...

Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, EarlyView.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

大器能成由别慧,人谋有补赖天工——生物学家威尔逊和他的科学成就
野生动物学报, 2003 2001年,联合国做出决议,将国际生物多样性日由原来的12月29日改为5月22日。“生物多样性”这个名词对许多中国人来说已经非常熟悉了,但知道这一名词的重要传播者是谁,恐怕寥寥无几。在生物多样性保护领域,不能不提及下面这位响当当的人物,而他对生物多样性保护的贡献只是其科学贡献的一小部分。他就是——

Conservation Biology, EarlyView.Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

Mangrove restoration by water quality improvement: A case of Dongzhaigang Bay, Hainan, China [PDF]
, 2016 受自然和人为活动的威胁，全球红树林严重退化，不仅红树林面积锐减，而且红树植物群落退化、生态功能受损。近几十年来红树林恢复得到广泛关注，世界各地开展了广泛的红树林恢复活动。人工造林是最常用的红树林恢复手段，但不适宜的造林不能有效地恢复红树林，而且中国红树林的宜林地面积有限，除人工造林外，还应该考虑其他手段。本研究以东寨港红树林为例，探讨不通过造林的红树林生态恢复措施。 2008年以来，东寨港红树林由于水产养殖和禽畜养殖的污染而严重退化。为改善东寨港的环境状况，2012年以来 ...

Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...
