黑面琵鷺瀕危 臺灣為最愛棲息地之一 | Taiwan – the endangered black-faced spoonbill’s favorite place

TAIPEI (The China Post) – Black-faced spoonbills, a water bird species, migrate to Taiwan every year as one of their wintering sites. The population of the endangered bird once falls to 300 and now it is 4,000 left in the world.

黑面琵鷺每年都會過境台灣,台灣是這種濱危鳥類的中繼休息站,但這種全球剩4000隻的鳥類,曾經群體數量降到不到300隻。

The black-faced spoonbill seems to love Taiwan’s environment dearly. In January, 2,500 birds were spotted twice in Taiwan, including three locations, 469 birds in Tucheng, Tainan, 389 birds in Budai, Chiayi County, and 267 birds in Qigu, Tainan.

黑面琵鷺似乎十分喜愛台灣的環境,但今年1月時,在台灣的兩次觀測中,都觀測到2500隻左右的黑面琵鷺,而台南土城觀測到469隻、嘉義布袋389隻、台南七股267隻,是數量最多的前三名。

On March 7, the Taiwan Council of Agriculture’s Endemic Species Research Institute published the research results conducted with the School of Life Science of National Taiwan Normal University (NTNU).

今(7)日臺灣農委會特生中心公開研究,此次與台灣師範大學生命科學專業學院合作。

The research team took two years to complete the world’s first sequencing of the genome of the black-faced spoonbill and around 1.19 billion draft genomes were discovered. It is hoped that the information and data obtained could make better contributions to the conservation and rehabilitative work.

歷經兩年時間,完成全球首度對黑面琵鷺基因組的完整定序,獲得黑面琵鷺約11.9億個鹼基對的基因組草圖,可望透過黑面琵鷺基因圖譜的揭露,更充分掌握保育和復育工作所需的資訊。

The number of black-faced spoonbills was as high as 50,000 in the Ice Age. The main reason for its decrease dates back from the 1990s’ war and the use of DDP insecticides.

冰河時期黑面琵鷺的數量高達5萬隻,但在1990年代減少的主因,主要是因為戰爭與DDP殺蟲劑的使用。

The deadly product could prevent water birds from breeding healthy offspring by causing the absorption of calcium to reduce and the frangibility of the eggshell. The findings could be speculated by observing the changes in genotypes along with historical events.

由於DDP會讓鈣質吸收減少,造成鳥類蛋殼易碎,讓黑面琵鷺無法健康的繁衍後代,而這些都能從基因型態的變化,再加上歷史事件的演變對比推估而成。
