Nan Fang Nong Cun Bao· 2025-05-22 06:36
Core Viewpoint - The discovery of the rare plant Eulophia zollingeri (leafless beauty orchid) in Guangdong Hongshan Forest Park highlights the park's high ecological environment and biodiversity, emphasizing its role as an urban ecological green lung [3][8][10]. Group 1: Discovery and Characteristics - Two rare specimens of Eulophia zollingeri were discovered for the first time in Guangdong Hongshan Forest Park [3]. - This plant is notable for its unique leafless feature and its reliance on underground tubers and symbiotic fungi for survival [4][5]. - The survival conditions for Eulophia zollingeri are extremely harsh, typically found only in unpolluted mountainous forests [7]. Group 2: Ecological Significance - The discovery indicates a high level of coordination and balance among the park's fungal communities, pollinating insects, and microclimate conditions, serving as strong evidence of ecosystem integrity [8][9]. - The presence of this species adds a unique ecological profile to Hongshan Forest Park and provides valuable samples for studying the adaptive evolution of orchids [13][14]. Group 3: Conservation Efforts - The park management plans to enhance ecological monitoring and explore more natural mysteries while conducting various educational activities to raise public awareness about endangered plants [16][17]. - Visitors are urged not to touch or pick rare plants to help protect this natural heritage [19][24]. Group 4: Protection Status - Although Eulophia zollingeri is not listed in the National Key Protected Wild Plant Directory, it is included in CITES Appendix II, indicating its status as a species under international protection [21]. - Its short flowering period (April to June) and unique survival mechanism make it a marker of high-quality ecological environments [22].

Core Viewpoint - The article emphasizes the importance of biodiversity and the urgent need for its protection, highlighting the interconnectedness of human fate and the survival of diverse species on Earth [2][7]. Group 1: Evolution of Life's Colors - The early Earth was predominantly brown, gray, and green, but has evolved into a vibrant world filled with colors due to various evolutionary processes [2][5]. - The evolution of vision played a crucial role in this color explosion, with the development of trichromatic vision around 541 million years ago coinciding with the Cambrian explosion, allowing organisms to better navigate their environments [4][5]. Group 2: Color Revolution in Flora and Fauna - The first color revolution was led by plants, which evolved colorful fruits and flowers approximately 300 to 377 million years ago to attract animals for seed dispersal and pollination [5][6]. - Animal color evolution began around 140 million years ago, with bright colors serving as survival signals for mating, deterring predators, or establishing dominance [5][6]. Group 3: Genetic Diversity and Endangered Species - The loss of genetic diversity is accelerating globally, particularly among birds and mammals, due to habitat destruction, disease, and human activities [10][11]. - A study involving 57 scientists from 20 countries assessed genetic diversity changes in 622 species over 30 years, revealing alarming trends but also highlighting the potential for effective conservation strategies [10][11]. Group 4: Strategies for Conservation - Five key strategies to maintain or restore genetic diversity in endangered species include: 1. **Population Supplementation**: Introducing new individuals to existing populations has shown significant positive effects on genetic diversity, especially in birds [11]. 2. **Population Control**: Removing individuals can sometimes enhance population health by reducing resource competition [12]. 3. **Ecosystem Restoration**: Restoring habitats can help maintain and even increase genetic diversity over time [13]. 4. **Control of Invasive Species**: Managing invasive species can aid in the recovery of endangered populations by reducing competition [14]. 5. **Conservation Translocation**: Establishing populations in new areas or reintroducing them to former habitats can be effective if managed properly [15]. Group 5: Individual Actions for Biodiversity - Individuals can contribute to biodiversity conservation through simple actions such as creating diverse gardens, protecting traditional crop varieties, participating in community conservation efforts, and being responsible in nature [17][18].
国际生物多样性日|守护“神话之鸟”
Zhong Guo Zi Ran Zi Yuan Bao· 2025-05-21 09:43
编者按:你刷到过"最诗意岗位"的新闻吗?每年夏天,都会有几名志愿者登上浙江的无人岛,守护被称为"神话之鸟"的中华凤头燕鸥——不仅能保护濒 危动物,还能享受海岛美景。2024年夏天,志愿者徐博文从3000多名报名者中脱颖而出,当了两个月的"孤岛守鸟人"。 2003年,陈水华带领团队调查了舟山群岛1300多座岛屿,发现了燕鸥家族的其他成员,但没能找到中华凤头燕鸥。2004年8月1日,调查团队在宁波市象 山县韭山列岛一座名为将军帽的无人岛上,找到了混群在近4000只大凤头燕鸥中的15只中华凤头燕鸥。 这两种燕鸥,同是鸥科凤头燕鸥属的近亲,体型相似。它们外形上的区别在于,中华凤头燕鸥羽色更白,喙大部分是橙黄色,喙尖黑色,曾被称为黑嘴 端凤头燕鸥。 然而,2004年夏季的两场台风使燕鸥群繁殖失败并再次消失。直到2007年6月,8只中华凤头燕鸥才又回到了将军帽岛。象山韭山列岛国家级自然保护区 专门派了一艘船守在小岛边,但在护岛船补充物资的空当,有不法分子趁夜盗走了所有鸟蛋。台风、人为干扰,以及蛇、鼠、游隼等天敌捕食是导致燕鸥等 野生海鸟种群繁殖失败的主要威胁因素。天灾人祸接踵而来,中华凤头燕鸥种群日益凋零。 幸好,200 ...

同步进行的还有鱼类调查。"去年我们对阳澄湖重要水域进行过调查,鱼类很丰富,希望这次有新的惊 喜。"赵冬福说,春末夏初是调查浮游动物、底栖动物、水生植物、鱼类的好时期,此次鱼类调查自然 收获不少,短时间内就发现了多条昂刺鱼和鳜鱼。 午后的阳澄湖在阳光的映衬下波光粼粼,几只水鸟掠过湖面。约30分钟后,两艘双体船缓缓停靠在阳澄 湖退养水域。南京大学环规院的调查人员快速拿出工具,在船尾寻找目标。调查员赵冬福拿出索伯网和 采泥器,扣好绳索慢慢沉入水中,待触底"咬住"底泥再拉上来。"采泥之后还得用湖水冲洗几遍,才能 将含有生物的底泥放进采样袋里,拿回去检测,检测结束后还要做好样本分析和整理。"赵冬福向记者 说道。 不远处,调查员郑孙元正用水草耙打捞水生植物。很快,一株3米多长的穗状狐尾藻被他高高举起,晶 莹的水珠顺着墨绿色茎秆滚落。"这是沉水植物优势种,为吸收到阳光,它们能长到惊人的长度。"郑孙 元和助手对多株水生植物进行称重记录后,将样本放入袋中封存。郑孙元说,阳澄湖沉水植物的种类较 丰富,其中不乏我们耳熟能详的苦草、荇菜、金鱼藻、菹草等。这些沉水植物在水中形成了翠绿而幽静 的"水下森林"。 昨天(5月14日)下午,苏 ...
