每日英語跟讀 Ep.981: About Nature - Key to butterfly climate survival may be colour coded
A butterfly’s ability to absorb or reflect heat from the sun with its wings could be a matter of life and death in a warming world, according to British research published Thursday calling for gardens, parks and farms to host shady, cooling-off spots.
根據英國研究機構週四發布的研究報告,由於全球日益暖化,蝴蝶翅膀吸收與反射太陽熱能的能力,可能攸關該物種的生死存亡, 呼籲花園、公園與農場設置遮陽、降溫設施。
While all butterflies are ectotherms - they cannot generate their own body heat - the ability to regulate temperature varies significantly, researchers said.
研究人員指出,雖然所有蝴蝶都是變溫動物,不能自體發熱,但蝴蝶調節溫度的能力差別很大。
The study found that bigger, pale-coloured butterflies, like the Large White or Brimstone species, are better at thermoregulation because they can angle their wings to reflect the sun’s heat either away from them or onto their bodies to attain the right temperature.
研究發現,體型較大、淺白色的蝴蝶,像是歐洲粉蝶(Large White)或是鉤粉蝶(Brimstone),比較能夠調節體溫,因為牠們能調整翅膀的角度,反射或吸收太陽的熱量,以調節合適體溫。

Gray parrots separated at zoo after swearing a blue streak 動物園灰鸚鵡因髒話不斷而被分開
A British zoo has had to separate five foul-mouthed parrots who keepers say were encouraging each other to swear.
英國一家動物園已不得不將5隻出口成「髒」的鸚鵡分隔開來,負責照顧鸚鵡的工作人員說,這些鸚鵡相互慫恿飆髒話。
Billy, Eric, Tyson, Jade and Elsie joined Lincolnshire Wildlife Centre’s colony of 200 gray parrots in August, and soon revealed a penchant for blue language.
比利、艾瑞克、泰森、傑德與艾爾西(今年)8月加入林肯郡野生動物中心的200隻灰鸚鵡大家族,但牠們很快就顯露對髒話的熱愛。
"We are quite used to parrots swearing, but we’ve never had five at the same time," said the zoo’s chief executive, Steve Nichols. "Most parrots clam up outside, but for some reason these five relish it." Nichols said no visitors had complained about the parrots, and most found the situation funny.
「我們很習慣鸚鵡說髒話,但從來沒有5隻同時飆髒話,」該動物園首席執行長史蒂夫.尼可斯說。「大多數鸚鵡在外頭就會冷靜下來,但這5隻不知為何仍對飆髒話樂此不疲。」尼可斯說,沒有訪客抱怨鸚鵡說髒話,大多數人覺得這情況很好笑。
