New research suggests that pandas may be at risk of dying out because they are too comfortable. Experts say too much happiness can stop the bears from searching for new mates.

新研究表明，大熊猫可能因为过于舒适而面临灭绝风险。专家表示，过多的幸福感会阻止这些熊寻找新伴侣。

Environmentalists have long believed that building roads or homes near the bears may threaten their survival by reducing or fragmenting their natural habitat, The Times reported. But the new research suggests that a "modest degree of discomfort and fragmentation" may actually help preserve panda populations.

据《泰晤士报》报道，环保主义者长期以来认为，在大熊猫附近修建道路或住宅可能会通过减少或分割其自然栖息地而威胁到它们的生存。但新研究表明，适度的不适和碎片化实际上可能有助于保护大熊猫种群。

The research was conducted by scientists from Michigan State University. It concluded that pandas fail to wander off in search of new mates if they find their habitat too comfortable, resulting in a lack of vital genetic diversity.

这项研究由密歇根州立大学的科学家进行。研究得出结论，如果大熊猫发现自己的栖息地过于舒适，它们就不会四处游荡寻找新伴侣，从而导致缺乏重要的遗传多样性。

For their study—outlined in a paper in the journal Conservation Biology—the team looked at genetic diversity and spread among a Chinese panda population. The ideal level of perfectly livable habitat was found to be only 80% of an area, with the remainder either too harsh or too affected by human activity.

在他们的研究中——概述在《保护生物学》杂志的一篇论文中——团队观察了中国大熊猫种群中的遗传多样性和分布。研究发现，理想情况下，完全适宜居住的栖息地只占一个区域的80%，其余部分要么过于恶劣，要么受人类活动影响过大。

The experts concluded that pandas should ideally "be happy enough to thrive, but not so content that they don't want to move around and find new mates".

专家们得出结论，理想情况下，大熊猫应该“快乐到足以繁衍，但不应满足到不想四处走动寻找新伴侣”。

Their conclusions about what The Guardian described as this "sweet spot" are in line with the so-called Goldilocks principle: that there can be just the right amount of something. The concept has been applied to a wide range of disciplines, from developmental psychology to economics and engineering.

他们关于《卫报》所描述的这个“最佳点”的结论，符合所谓的金发姑娘原则：即某物可以恰到好处。这一概念已被应用于广泛学科，从发展心理学到经济学和工程学。

Claudio Sillero, a professor of conservation biology at Oxford University, told the newspaper that the new findings could have implications beyond panda conservation.

牛津大学保护生物学教授克劳迪奥·西列罗告诉该报，这些新发现可能对大熊猫保护以外的领域具有启示意义。

"Most large animals that eat meat live in increasingly fragmented landscapes," said Sillero, who was not involved in the research. "It may well be that the messy nature of their relationship with human efforts induce more animals to scatter or travel further, and might result in greater genetic connectivity and enhanced population persistence."

“大多数肉食性大型动物生活在日益碎片化的景观中，”西列罗说，他并未参与这项研究。“很可能，它们与人类努力之间的混乱关系性质，促使更多动物分散或走得更远，并可能导致更大的遗传连通性和增强的种群持久性。”

The most recent count of pandas found that there were more than 1,800 left in the wild, putting them on the list of vulnerable, but not endangered, species.

最近一次大熊猫统计发现，野外仍有超过1800只大熊猫，使它们被列入易危但非濒危物种名单。
