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.

B | 明米集团创始人雷军周四在接受彭博社采访时表示，下一代5G网络的到来有望刺激该公司对智能手机的需求。

C | 他也忽视了小米库存的抛售。仅在过去三个交易日，小米的市值就蒸发了60亿美元。雷军在接受采访时表示，公司目前的重点是向高端市场进军，同时向欧洲扩张，并停止进入美国市场。他没有概述避开美国市场的原因。美国是世界上最大的经济体，曾经被认为是一个有前途的小米市场，但对中国企业越来越不友好。”“在过去的两三年里，我们已经进入了大约80个国家和地区，”雷军说。我们希望这种势头将继续下去。”周四，小米宣布推出自己品牌的更便宜的红米手机，以便开始提高其旗舰手机的价格和配置。小米进入高端市场之际，智能手机市场正处于鼎盛时期，中国经济增长正在放缓。然而，华为和其他竞争对手已经在高端手机市场占据了一席之地，并开始占领苹果的领地。尽管雷军拒绝透露经济放缓对小米业务可能产生的影响，但他表示，5G不仅可以促进智能手机的需求，还可以促进小米互联网服务的发展。小米互联网服务现在覆盖了从在线音乐到电影的所有服务领域，共服务2.2亿用户。”智能手机在中国的普及率已经很高了。但我认为，我们正处在5G的前夕，我相信，当5G手机流行时，中国对智能手机的总体需求将恢复。自从周二数十亿股限制性股票被提升以来，小米的市值蒸发了17%。几位分析师本周下调了小米目标股价和预期。

D | 小米曾经被认为价值1000亿美元，但现在只相当于这个价值的三分之一。然而，小米自诞生以来发展迅速。自第一轮融资以来持有小米股份的股东可以获得可观的利润。Millet在其招股说明书中表示，在2010年推出的一轮融资中，投资者认购了39亿股股票，低于每股2港元。
