通緝外來鬣蜥

April 29, 2026

在台灣，入侵物種綠鬣蜥（𝘐𝘨𝘶𝘢𝘯𝘢 𝘪𝘨𝘶𝘢𝘯𝘢）與當地原生物種爭奪資源，破壞生態系統，並影響當地農業。當地政府培訓專業獵人協助捕捉這些鬣蜥，並以獎金作為回報；去年共捕獲26萬隻鬣蜥。綠鬣蜥最初透過寵物交易被引入台灣，相信是因意外逃脫或原主人棄養而被放生。

In Taiwan, the invasive green iguana (𝘐𝘨𝘶𝘢𝘯𝘢 𝘪𝘨𝘶𝘢𝘯𝘢) competes with native species for resources, damaging ecosystems and local agriculture. The local government trains and rewards certified hunters to capture these iguanas; 260,000 were captured last year. Green iguanas were introduced to Taiwan through the pet trade, likely after escaping or being released by former owners.

雲霧林中的離地公廁

April 28, 2026

研究發現，哥斯達黎加雲霧林中的多種哺乳動物會利用絞殺榕（𝘍𝘪𝘤𝘶𝘴 𝘵𝘶𝘦𝘳𝘤𝘬𝘩𝘦𝘪𝘮𝘪𝘪）的特定樹枝交界處作為公共廁所。絞殺榕獨特的生長形態形成許多平坦的高空平台；研究人員以紅外線相機記錄到17種不同的哺乳動物會到訪這些平台排便，並透過氣味交換社交訊息。

Researchers found that various cloud-forest mammals in Costa Rica use specific tree junctions of the strangler fig (𝘍𝘪𝘤𝘶𝘴 𝘵𝘶𝘦𝘳𝘤𝘬𝘩𝘦𝘪𝘮𝘪𝘪) as shared latrines. The strangler fig’s unique growth form creates flat platforms high in the canopy. Using camera traps, researchers recorded 17 different mammal species visiting these sites to defecate and to exchange social information via scent.

全球暖化再讓兩物種列瀕危

April 28, 2026

皇帝企鵝與南極毛皮海獅現已被列為瀕危物種。全球暖化是導致牠們數量下降的主要原因。海水溫度上升與海冰減少影響海獅主要食物來源——南極磷蝦的數量。企鵝的繁殖、孵卵與育雛都依賴海冰，因此海冰減少也使牠們的繁殖成功率下降，進而面臨滅絕風險。

The emperor penguin and the Antarctic fur seal are now listed as endangered. Global warming is a major cause of their population declines. Rising ocean temperatures and reduced sea ice are affecting the availability of the seals’ main food source, Antarctic krill. As sea ice disappears and fewer reliable platforms are available for penguins to breed, incubate eggs, and rear chicks, their breeding success rate declines, putting them at risk of extinction.

放歸前缺乏研究導致死亡

April 7, 2026

研究發現，將獲救的孟加拉懶猴放歸野外常導致死亡。研究追蹤了被放歸的懶猴，發現9隻中有7隻在放歸後數週內死亡，其中多數是被其他懶猴殺死。這表明目前的放歸方式缺乏對棲息地飽和度與懶猴社會行為的研究。研究建議，相較於試圖修正放歸計畫，打擊非法販運與防止棲息地喪失更為有效。

A study found that releasing rescued Bengal slow lorises into the wild often results in fatalities. The researchers tracked released lorises and found that seven of nine died within weeks of release, most killed by other slow lorises. This indicates that current reintroduction methods lack research on habitat saturation and the species’ social behavior. The study suggests that combating illegal trafficking and preventing habitat loss is more effective than trying to fix the release program.

社交群組用暗號販賣動物

March 31, 2026

透過調查與臥底行動，記者揭露了印尼多個販售瀕危野生動物的 Facebook 群組，其中包括犀鳥、銀長臂猿等受保護物種。這些平台使用暗語以規避網絡審核。Meta 以違反禁止交易受限物品的政策為由，關閉了九個涉事群組。

Through investigations and undercover operations, reporters exposed multiple Facebook groups in Indonesia that were trafficking protected, endangered wildlife, including rhinoceros hornbills and Javan silvery gibbons. These platforms used coded language to evade moderation. Meta deactivated nine implicated groups, saying they violated its policy prohibiting the trade of restricted items.
