数十年来,阿富汗境内发生的战争与非法捕猎使得雪豹列入濒危物种名单。


美国国务院国际信息局(IIP)«美国参考» 从华盛顿报道,发现1000万种生命形式、对其进行描述并编目分类是一项浩繁的工程,但一群国际科学家们在生命科学杂志《系统学与生物多样性》(Systematics and Biodiversity)上刊登的一篇文章中提出了这项挑战。这39位科学家、学者和工程师建议:在无数生命形式遭到灭绝之前,今后50年内应对地球生物圈中的物种进行编目分类。

今年3月30日发表的这篇文章说:“事实证明,即使经过多个世纪的探索,地球的生物圈仍属于有待探索的广阔领域,对此我们仍然所知不多。探索生物圈与探索宇宙十分相像。我们知道得越多,生物圈及其历史就显得越复杂、越令人惊讶。”

已知的地球物种有200万种,新发现的物种按每年约18,000种的速度增加。专家们估计,还有1000万个物种既没有被科学发现、又没有编目分类。成千上万个物种可能遭受栖息地丧失或被其他物种或人类活动侵占的威胁。

据美国一位著名的生物多样性专家、密苏里植物园(Missouri Botanical Garden)退休园长彼得·雷文(Peter Raven)说,约30%的地球物种可能在本世纪灭绝。“物种灭绝的速度有可能在人类历史上第一次超过物种发现的速度。”

撰写这篇文章的作者们来自一系列学术机构和自然历史机构。他们呼吁“担当起探索并记录地球物种的全面重任。他们还呼吁建立不仅包括生态学家和生物学家而且包括信息科学家和工业项目经理在内的广泛伙伴合作关系。

柏林自然历史博物馆(Museum of Natural History in Berlin)馆长约翰内斯·福格尔(Johannes Vogel)说:“我们具有为了实现一项十分崇高的事业——发现和了解我们生活居住的星球——综合利用科学、工业和社会力量迅速发现生物多样性所需的知识和技术能力。”

作者们还强调在扩大人类对生物圈了解方面取得进展的迫切性。

文章作者的第一署名人、在亚利桑那州立大学(Arizona State University)全球可持续性研究所(Global Institute of Sustainability)工作的一名可持续性研究领域资深科学家昆廷·惠勒(Quentin Wheeler)说:“环境变化和物种灭绝的速度表明我们需要一份全面的物种清单,而且现在就要。如果不对地球的物种继续探索、描述和分类,我们有可能错过从自然选择中理解如何解决无数与我们自己可持续生存有关问题的许多绝佳的机会。”

许多物种遭到灭绝的可能性迫在眉睫,增加了这个项目的紧迫性;同样迫切需要解决的问题是,接近退休的动植物科学专家还没有来得及把他们的知识传授给下一代。

文章作者之一、在西班牙马德里国家自然科学博物馆(National Museum of Natural Sciences)工作的安东尼奥·瓦尔德卡萨斯 (Antonio G. Valdecasas)说:“没有这类信息与技能,对自然的研究就像是在黑箱中进行调查。”

文章提出了一项行动计划,要求建立一套标准程序指导收集与描述工作,把从此刻起收集的物种添加至已收集到的物种中。它还要求增加这项工作的人力资源,包括业余爱好者和专业人员,在研究基础设施中应用数码技术,并在国际科学界和自然历史博物馆之间实行进一步协调。

合作撰写这份研究报告的科学家分别属于不同的机构,其中包括:马萨诸塞州伍兹·霍尔海洋生物学实验室(Woods Hole Marine Biology Laboratory)、纽约植物园(New York Botanical Garden)、纽约美国自然历史博物馆(American Museum of Natural History, New York)、美国农业部(U.S. Department of Agriculture)、维也纳大学(University of Vienna)。

《系统学和生物多样性》(Systematics and Biodiversity)是伦敦自然历史博物馆(London’s Natural History Museum)出版的一份生命科学杂志。

Understanding All Earth’s Life Forms Is Urgent Task to Begin

06 April 2012

Decades of war and illegal hunting in Afghanistan have put the snow leopard on the endangered species list.

 

Washington — Discovering, describing and cataloging 10 million life forms is a tremendously large undertaking, but an international group of scientists presents that challenge in an article in the life sciences journal Systematics and Biodiversity. This group of 39 scientists, scholars and engineers proposes that Earth’s biosphere be fully cataloged in 50 years before untold numbers of life forms are driven extinct.

“Earth’s biosphere has proven to be a vast frontier that, even after centuries of exploration, remains largely uncharted,” the March 30 article says. “Exploring the biosphere is much like exploring the universe. The more we learn, the more complex and surprising the biosphere and its story turn out to be.”

Two million of Earth’s species are known, and new discoveries increase that number by about 18,000 each year. Experts estimate that another 10 million species are neither recognized nor cataloged by science. Thousands of species are potentially threatened by loss of habitat, encroachment of other species or human activity.

Approximately 30 percent of Earth’s species could become extinct this century, according to one prominent U.S. expert on biodiversity, Peter Raven, president emeritus of the Missouri Botanical Garden. “For the first time in human history, the rate of species extinction may exceed that of species discovery.”

The article’s authors, hailing from a range of academic and natural history institutions, call for a “comprehensive mission to explore and document Earth’s species.” They call for a wide-ranging partnership including ecologists and biologists, but also information scientists and industrial project managers.

“We have all the intellectual and technological capacity for rapid biodiversity discovery, combining the power of science, industry and society for a most noble cause: discovering and understanding the planet we inhabit,” said Johannes Vogel, director of the Museum of Natural History in Berlin.

The authors also emphasize the urgency for progress in broadening human understanding of the biosphere.

“The pace of environmental change and species extinctions indicates that we need a comprehensive inventory of species and we need it now,” said Quentin Wheeler, the lead author of the article and a senior sustainability scientist at the Global Institute of Sustainability at Arizona State University. “Without exploring, describing and classifying Earth’s species we may miss many of our best opportunities to learn from natural selection how to solve countless problems related to our own sustainable survival.”

The looming potential extinction of many species adds urgency to the project, as does the near-term retirement of a generation of scientific experts in flora and fauna who have not passed their knowledge to a new generation.

“Without this information and these skills, studying nature will be like introducing a probe into a black box,” said article co-author Antonio G. Valdecasas, with the National Museum of Natural Sciences in Madrid, Spain.

The article lays out an action plan, calling for a standard set of procedures for collection and description of all specimens added to collections from this point forward. It also calls for a broader workforce to be applied to the work, including amateurs and professionals, the implementation of digital technologies in research infrastructure and greater coordination among international scientists and natural history museums.

Scientists who co-authored the study are affiliated with a range of institutions, including the Woods Hole Marine Biology Laboratory in Massachusetts; the New York Botanical Garden; the American Museum of Natural History, New York; the U.S. Department of Agriculture; and the University of Vienna.

Systematics and Biodiversity is a life science journal published for London’s Natural History Museum.
