中新网重庆2月14日电 题："生态守岁人"护山三十五载 续写世遗生灵"家谱" 作者 梁钦卿 "每次巡护，既要查看是否有人为破坏痕迹，也要观察植物长势与动物活动踪迹，同时排查火灾隐患， 发现问题还要及时反馈。"周厚林说，自己每年要进山七八十次，一年的徒步里程至少500公里，累计爬 升高度近10万米。常年在深山穿梭，他的裤子总被磨得起毛，鞋一年也要穿坏五六双。 沿着崎岖小路深入群山腹地，一侧是苍翠树木恣意生长，另一侧便是陡直垂落的断崖。崖下数十米处， 湍急河水奔腾不息。这样的险径，周厚林走得从容稳当。 周厚林在重庆五里坡国家级自然保护区中巡山。中新网记者 何蓬磊 摄 2月9日， 周厚林正在采集大叶桂樱的枝叶。中新网记者 何蓬磊 摄 清晨的雾尚未散尽，重庆五里坡国家级自然保护区高级工程师周厚林已换上登山鞋、穿好冲锋衣，利落 地背上背包，手握一根磨得发亮的竹杖，再次走进五里坡的深山之中。 五里坡地处巫山县东北部，总面积逾3.5万公顷。2021年，五里坡通过湖北神农架世界自然遗产地边界 微调，成功跻身世界自然遗产行列。这里地形复杂，沟壑纵横、重峦叠嶂，海拔落差大，成为众多珍稀 动植物的隐秘家园。 2月9日， 近日，笔者 ...

科研团队于2025年在花坪保护区内海拔1200至1400米的山间溪流及周边森林地表采集到该物种标本。通 过形态比较和分子系统发育分析（基于线粒体16S rRNA基因）方法，研究人员确认该种群构成一个独 立且高支持率的进化支系，其姐妹种为分布于广西猫儿山的猫儿山掌突蟾（L.maoershanensis），两者 间的遗传距离（p-距离）达3.0%，高于或接近许多已被广泛承认的掌突蟾物种对之间的差异，形态特征 亦具有明显差异，符合新物种界定标准。 花坪掌突蟾体型较小，雄性体长25.0毫米至27.6毫米，雌性29.2毫米。其背部呈黄褐色至深褐色，散布 深棕色斑纹，腹部乳白色，眼睛虹膜为双色，上半部棕色、下半部银色，具有明显的鼓膜和不发达的黑 色颞褶线纹。该物种指、趾侧均具窄缘膜，趾间蹼退化，背部皮肤粗糙具小疣粒，无皮肤棱。 经济观察网 据央视新闻客户端消息，近日，广西自然博物馆、广东环境保护工程职业学院及中国科学 院成都生物研究所等多家单位的科研人员在国际动物分类学权威期刊《Zootaxa》上联合发表论文，正 式描述并命名了一种发现于广西花坪国家级自然保护区的两栖动物新种——花坪掌突蟾（Leptobrachella ...

Core Insights - A research team has discovered three new species in Danxia Mountain, Guangdong Province: Danxia Blue, Danxia Chicken Oil Mushroom, and Danxia Micro Water Beetle, highlighting the area's biodiversity and ecological significance [2][3][4] Group 1: New Species Discovery - Danxia Blue is a perennial herb that grows in humid sandstone environments at altitudes of 250-450 meters, blooming with purple-blue flowers for only two weeks each year [4] - Danxia Chicken Oil Mushroom is a rare edible fungus with a golden color, found under broadleaf forests, and has the potential to be cultivated for culinary use [5] - Danxia Micro Water Beetle is the smallest known member of the dragonfly family in China, measuring only 1.7-1.8 millimeters, and serves as an indicator species for the purity of the micro aquatic environment [5][6] Group 2: Ecological Importance of Danxia Mountain - Danxia Mountain is home to over 2,000 species of higher plants, 500 species of vertebrates, and thousands of insect fungi, with estimates suggesting that this may only represent 60%-70% of the actual species present [9][10] - The unique geographical structure and ecological environment of Danxia Mountain create isolated "island-like" habitats that promote independent evolution of species, leading to high biodiversity [10] - The area is described as an "evolutionary island," where species have developed distinct characteristics due to physical barriers, making each new species discovery significant in understanding life's resilience [10]

Core Insights - A recent study indicates that the "life map" of Earth is far from complete, entering a "golden age" of species discovery, with over 16,000 new species recorded annually, significantly outpacing extinction rates [1] - The research, published in the latest issue of *Science Advances*, analyzed data from approximately 2 million confirmed species, revealing that from 2015 to 2020, more than 16,000 new species were documented each year, including over 10,000 animals (primarily arthropods and insects), 2,500 plants, and 2,000 fungi [1] - The study challenges the old notion that species discovery is nearing exhaustion, suggesting that there may still be tens of thousands of unknown fish and amphibian species, with the total number of plant species potentially exceeding 500,000 [1] Methodology and Implications - Although new technologies like DNA analysis are accelerating the discovery of "hidden species," most new species are still identified through traditional morphological methods [2] - The discovery of new species is not only crucial for scientific understanding but also has significant practical implications, as only scientifically described species can be effectively protected [2] - New species discoveries often lead to breakthroughs in medicine and technology, such as weight-loss drugs derived from lizard venom and super-adhesive materials inspired by gecko feet [2] Future Directions - The research team plans to focus on analyzing geographic hotspots for species discovery in their next steps [3]

Core Viewpoint - A new species of the genus "Zanxia," named "Muli Zanxia," has been discovered in the Yalong River basin of Muli County, Sichuan, and this finding has been published in the journal Phytotaxa [1][4]. Group 1: Discovery and Characteristics - The new species "Muli Zanxia" is an annual herbaceous plant characterized by yellow-green flowers with purple-brown veins and elongated oval-shaped nectar glands [2][3]. - It primarily grows in the river valley shrubland of the Yalong River basin at an altitude of 2200-2400 meters [3]. Group 2: Collaborative Efforts - The successful publication of this research is attributed to the close collaboration between local enthusiasts and the research team, who collected and sent complete flowering specimens for identification [4]. - Muli County has been recognized as a traditional biodiversity center in the Hengduan Mountains, with several new species, including "Muli Chinese lettuce" and "Muli yellow wild vegetable," being discovered in recent years [4].

Core Viewpoint - The discovery of a new species of the genus Euphorbia, named "Xishui Bajianglian," adds valuable samples to the medicinal plant resource database and highlights the rich biodiversity of medicinal plants in Guizhou Province [1][2] Group 1: Discovery and Characteristics - A unique species of the Euphorbia genus was discovered in the Xishui National Nature Reserve, confirmed as a new species through morphological comparison and molecular evidence [1] - The "Xishui Bajianglian" grows in the valley areas of evergreen broadleaf forests, with distinct morphological features such as smooth, hairless leaf backs, flower stalks, and sepals, and flower clusters ranging from 8 to 20 [1] - The wild population of this species is limited to over 200 individuals, indicating its rarity and specialized habitat [1] Group 2: Conservation and Research Significance - All species of the Euphorbia genus are classified as nationally protected wild plants, with the discovery contributing to the total of 258 recorded species of nationally protected wild plants in Guizhou Province [2] - The active components of Euphorbia species, including euphorbia toxin, have therapeutic effects on various ailments and potential development value in fields such as anti-tumor and anti-venom research [1] - The discovery is part of a project organized by the National Forestry and Grassland Administration and the Guizhou Provincial Forestry Bureau, emphasizing the importance of conservation efforts in the region [2]
