Adelie penguin population sees rapid decline: Scientists_我的网站

金牌调解

A | Canberra, Oct 12 (UNI) Australia's top Antarctic scientists have reported a rapid decline in a population of Adelie penguins.

According to research published by the Australian Antarctic Division (AAD) on Tuesday, a large Adelie population off the East Antarctic coast has declined by 43 per cent over the last decade.

Ecologists from the AAD, led by Louise Emmerson and Colin Southwell, surveyed 52 islands along the 100-km coastline.

They found the number of occupied nests fell from 176,622 to 99,946 in that period.
Their findings are contrary to other Adelie penguin populations in east Antarctica where numbers have been stable.

The most widespread penguin species, the Adelie is found along the entire Antarctic coast. Models had predicted the particular population observed by the AAD would continue to grow.

Researchers concluded a change in environmental conditions was the cause of the decline.

"We think this population decline was initially triggered by five years of extensive summer sea ice adjacent to the colony in the mid-2000s, which hampered access to the adults' foraging areas and saw virtually no chicks survive," Emmerson said in a media release.

"The frequency of these unfavorable breeding conditions subsequently remained high, and fledgling survival also began to decrease. These two processes together resulted in a more rapid population decline than would be expected if they had been acting in isolation."

She warned that the smaller the population becomes the harder it will be for individuals to survive.

"It may be that the old adage of safety in numbers is playing out for the fledglings in the vast and harsh Southern Ocean, although exactly why and how needs further investigation," Emmerson said.

俄罗斯总统普京将于明天（16日）起展开对中国的国事访问。如何进一步夯实双方政治互信，推动务实合作，将成为普京此访的重要议题。

普京总统在新任期开始之初随即访华，双方将就两国关系和共同关心的战略性问题展开深入交流。如此关键时间点进行的此轮中俄高层互动，也将为两国关系发展和未来合作，作出战略性规划和顶层设计。

2023年中俄双边贸易额达到创纪录的2401.1亿美元。

C | 今年一季度，两国双边贸易额达566.8亿美元，同比增长5.2%，继续保持良好发展势头。在乌克兰危机延宕的背景下，“加强务实合作”无疑是普京此访的一个关键议题。而对于发展中俄关系，中方也明确表示，维护好、发展好中俄关系，既是中俄作为两大邻国的必然选择，也完全符合两国人民根本利益。

D | 中俄之间的合作既不针对第三方，也不受第三方干扰和胁迫。

中国国际问题研究院欧亚所所长李自国：对这次普京访华的期待，首先我觉得对俄罗斯来说、对中国来说，都要再一次明确中俄关系的性质。

E | 中俄关系是一个稳定的、可持续的、自主性的双边关系。中俄关系的基础是睦邻友好、相互尊重、平等相待、合作共赢。再就是务实合作领域，可能是双方需要关注的一个重点，可能也是亮点。包括中俄双边已经有一个比较大的贸易额。

F | 大项目里面，比如交通物流领域、能源领域、创新和科学领域，我想这些领域（合作成果）可能会在普京访华当中体现出来。

俄罗斯是今年金砖国家轮值主席国，而中国也将在下半年接任上合组织轮值主席国。除了双边关系之外，普京总统访华期间，中俄如何就重大国际和地区热点问题开展沟通协调，同样备受外界高度关注。

中国国际问题研究院欧亚所所长李自国：大家都觉得世界进入一个动荡变革期，而这种动荡变革期会怎么样，需要（中俄）双方进行对表。

G | 我们需要了解对方如何建设一个公平合理的国际秩序。这是我觉得除中俄双边（话题）之外重要的一个话题。还有一个就是，比如地区冲突，中东地区的危机、巴以冲突的危机、乌克兰的危机，包括俄罗斯也是当事方之一。这种地区冲突的不确定、不稳定性的因素如何去消减，应该是双方对话的一个内容。
