□吴倩倩 遇到困境不可怕,可怕的是你没有做出努力。 在中国数字植物标本馆(CVH)这个平台,输入"普陀鹅耳枥"会看到50条检索记录,按照时间排序,最早的采 集记录来自于1930年,这是时年62岁的钟观光先生1930年5月15日在浙江普陀佛顶山采集的。这次采集一 共制作成三份标本,两份是有花无果的完整枝条,另一份只有零散的几片叶子,猜测是做标本时掉落或者剪 切下来的小枝,舍不得扔,也做成了一份标本。 这是国人对于普陀鹅耳枥的第一份记录。 1932年,在中国科学社生物研究所任职的郑万钧先生接触到了那两份标本,经过郑先生鉴定,认定其为桦木 科鹅耳枥属中的一个新种,因其采自普陀,便将其命名为"普陀鹅耳枥",学名为Carpinus putoensis W. C. Cheng,文章发表在中国科学社生物研究所丛刊。其中Carpinus为其属名,意为鹅耳枥属,putoensis为其 种名,为中文"普陀"的拉丁化写法,W.C. Cheng即为郑万钧先生姓名的威氏拼音写法,这是我国在1958年 推广汉语拼音方案前,用拉丁字母注音汉字的方式。 仔细查看,你会发现这里面隐藏着很多信息。首先是标本的完整度和精美度,不得不说,再回看那3 ...

Core Viewpoint - The successful flowering of the critically endangered Guangxi Fire Paulownia in Nanning Tree Garden marks a significant achievement in conservation efforts for this rare species, highlighting its ecological importance and the need for ongoing protection [1][2] Group 1: Ecological Significance - Guangxi Fire Paulownia is a unique and critically endangered tree species endemic to China, characterized by its tall trunk and "flowers before leaves" growth habit, which offers high ornamental value [1] - Its extensive root system plays a crucial role in stabilizing poor limestone soils and maintaining regional ecological balance, making it an essential ecological guardian [1] Group 2: Conservation Status - The species has a very narrow natural distribution, primarily found in the limestone areas of central to southern Guangxi, with a sparse population and significant challenges in natural regeneration [1] - It is classified as critically endangered (CR) by the International Union for Conservation of Nature and is included in China's biodiversity red list, as well as being designated as a national key protected wild plant [1] Group 3: Research and Development - The flowering of Guangxi Fire Paulownia is part of a forestry research project funded by the Nanning Tree Garden, which began in 2020 and involved the collection and preservation of 35 germplasm samples [2] - The establishment of a 30-acre introduction and acclimatization trial forest aims to provide valuable samples for studying the species' adaptability to ex-situ conservation and for developing large-scale artificial propagation methods [2]

Core Points - The article highlights the ecological, scientific, and cultural significance of the rare species, the milu deer, in China, particularly in the Dongting Lake National Nature Reserve [2] - The Dongting Lake management has established a rescue center for injured or sick milu deer, equipped with professional medical facilities and staff to ensure timely assistance [2] - The management has also constructed flood refuge platforms to protect milu deer from frequent flooding during the rainy season [2] - In 2016, 16 milu deer were introduced from Jiangsu to enhance genetic diversity and adapt to environmental changes, contributing to the ecological balance in the region [3] - The population of milu deer in the reserve has increased to 323, showing significant growth since the initial protection efforts began [3]
