酷带英语｜双语精读：拯救海南长臂猿

Study aims to boost Hainan gibbon numbers

我是小酷，一起精读这篇新闻报道吧~

文章导读：

本文聚焦于海南长臂猿这一濒危物种的保护，介绍了范团队的研究成果。文章探讨了海南长臂猿面临的生存挑战，如栖息地退化、种群数量稀少及遗传多样性低等问题，并提出了基于科学的保护建议，如建设栖息地走廊和谨慎开展圈养育种计划。这些措施旨在为海南长臂猿的种群恢复提供新希望，也为全球生物多样性保护提供了有益参考。

第一部分：

Titled“Science-based suggestions to save the world's rarest primate species Nomascus hainanus”, it offers a fresh perspective on the Hainan gibbon's situation and a glimmer of hope for the species' future.

它标题为“基于科学的建议，旨在拯救世界上最稀有的灵长类动物Nomascus Hainanus”，它为海南长臂猿的处境提供了新的视角，并对该物种的未来充满希望。

Fan and his team believe that despite the gibbons' dwindling numbers, the quality of their current habitat is surprisingly not poor. Instead of focusing solely on improving the existing environment, they argue that the priority should be expanding the gibbons' accessible habitat.

范和他的团队认为，尽管吉本斯的数字减少，但他们目前的栖息地的质量令人惊讶地并不贫穷。他们认为，优先级应该扩大长臂猿的可及栖息地，而不是仅仅专注于改善现有环境。

They suggest building habitat corridors to rapidly increase the habitat available to the gibbons, a vital step in mitigating the chances of inbreeding — a significant threat given their low genetic diversity.

他们建议建造栖息地走廊，以迅速增加长臂猿可用的栖息地，这是减轻近亲繁殖机会的重要一步，鉴于它们的遗传多样性低，这是一个重大威胁。

第二部分：

The team emphasizes that capturing wild gibbons to establish a captive breeding program should be approached with extreme caution. Such an action could diminish the already limited genetic diversity of the population, exacerbating the risk of inbreeding depression — the reduced survival and fertility of offspring from related individuals.

该团队强调，对于捕获野生长臂猿以建立圈养繁殖项目这一举措，必须极其谨慎地对待。这样的行为可能会降低本就有限的种群遗传多样性，加剧近亲繁殖衰退的风险——近亲个体所产生的后代，其生存能力和繁殖能力会降低。

Their recommendations are rooted in robust analysis of years of data.

他们的建议植根于对多年数据的强大分析。

“The protection of biodiversity is one of humanity's core tasks,” Fan told China Daily. “Saving critically endangered species with tiny populations is a key, yet extremely challenging, aspect of biodiversity conservation, and there are few successful cases.”

范说：“保护生物多样性是人类的核心任务之一。” “以微小的种群拯救濒临灭绝的物种是生物多样性保护的关键，但极具挑战性的方面，几乎没有成功的案例。”

He explained that when a population falls below a certain threshold, it enters an extinction vortex, where random events such as fluctuations in population size, environmental instability and genetic drift — change in gene variant frequencies in a population from generation to generation that occurs due to chance events — continually threaten its survival.

他解释说，当一个种群数量下降到一定阈值以下时，它就会陷入灭绝旋涡。在这种情况下，诸如种群规模波动、环境不稳定以及遗传漂变（即种群中基因变异频率因偶然事件而逐代发生的变化）等随机事件会持续威胁到该种群的生存。

第三部分：

Habitat degradation and accompanied nutritional deprivation, genetic issues such as inbreeding depression and genetic bottlenecks, and extreme events like severe weather can accelerate extinction or impede population recovery.

栖息地退化以及随之而来的营养匮乏、近亲繁殖衰退和遗传瓶颈等遗传问题，还有诸如恶劣天气之类的极端事件，都可能加速物种灭绝或阻碍种群数量的恢复。

In such dire circumstances, human intervention, such as habitat restoration and captive breeding, becomes essential, Fan said.

范说，在这种严峻的情况下，人类干预，例如栖息地恢复和圈养繁殖，变得至关重要。

“But these interventions must be based on solid scientific evidence,” he added. “Otherwise, significant resources may be wasted on inefficient or ineffective conservation efforts, and may even have a negative impact on the species.”

他补充说：“但是这些干预措施必须基于可靠的科学证据。”“否则，可能会浪费大量资源来浪费效率低下或无效的保护工作，甚至可能对该物种产生负面影响。”

测一测：

1. What is the main goal of the study mentioned in the article?

A. To improve the existing habitat quality of the Hainan gibbon

B. To expand the accessible habitat range of the Hainan gibbon

C. To establish a captive breeding program for the Hainan gibbon

D. To increase the genetic diversity of the Hainan gibbon

2. According to the article, what is one of the biggest threats facing the Hainan gibbon?

A. Poor habitat quality

B. Inbreeding

C. Hunting

D. Climate change

答案1：B

解析：文章中提到，范和他的团队认为，尽管海南长臂猿的数量在减少，但其目前的栖息地质量并不差。他们建议优先扩大长臂猿的可及栖息地范围，而不是仅仅专注于改善现有的栖息地环境。因此，研究的主要目标是扩大栖息地范围，以帮助长臂猿的生存和繁衍。

答案2：B

解析：文章指出，海南长臂猿面临的重大威胁之一是近亲繁殖（inbreeding）。由于种群数量稀少，遗传多样性低，近亲繁殖会导致后代的生存能力和生育能力下降，进一步威胁其种群的延续。
