海藻令小海龜更難爬到海洋

September 11, 2025

研究人員針對三種幼海龜進行研究，發現由於海灘上馬尾藻數量增加，牠們爬入海中的總耗時延長了 54% 至 175%。幼海龜在海灘上停留的時間越長，遭受捕食、過熱及脫水的風險便越高。馬尾藻是一種漂浮於海洋中的海藻，其大規模藻華主要由氣候變遷與營養物質污染所引發。

Researchers studied three species of sea turtle hatchlings and found that their total crawl time to reach the ocean had increased by 54% to 175% due to the growing amount of sargassum on the beach. The longer these hatchlings remain on the beach, the greater their risk of predation, overheating, and dehydration. Sargassum is a type of seaweed that floats in the ocean, and its blooms are mainly driven by climate change and nutrient pollution.

設人造水源減衝突

August 28, 2025

虎貓是墨西哥的瀕危物種，主要受到棲息地喪失、捕獵以及氣候變遷的威脅。乾旱時期，虎貓常會進入人類居住範圍尋找水源，進而與人類發生衝突。為減少衝突，保育團體設計並建造了 13 套連接塑膠水槽的集水系統，並在人煙稀少的地點設置人造水源，提供虎貓飲用。除了虎貓之外，其他野生動物，例如長尾虎貓和彭氏鹿，也被觀察到使用這些水槽。

The ocelot is an endangered species in Mexico, threatened mainly by habitat loss, hunting, and climate change. During dry periods, ocelots often enter human settlements in search of water, leading to conflicts with people. To address this, NGOs designed and installed 13 water-collection systems with plastic troughs, placed in remote areas to provide ocelots with an alternative water source and reduce conflict. In addition to ocelots, other wildlife such as margays and Yucatán brown brockets have also been observed using these troughs.

極相似蝴蝶靠費洛蒙相認

August 26, 2025

超過400種綃蝶族蝴蝶分佈於中美及南美洲。牠們許多都具有相似的顏色圖案，以警告捕食者牠們有毒。研究發現，其中一些幾乎完全相同的蝴蝶是透過分泌獨特的費洛蒙，以吸引同類繁殖。這次研究鑑定出6個新物種，並發現這些蝴蝶演化如此迅速是因染色體重排頻率較高。研究人員希望這些發現能幫助未來的生物多樣性及保育研究。

There are over 400 species of glasswing butterflies across Central and South America. Many share similar color patterns that warn predators they are poisonous. A recent study discovered that some of these almost identical butterflies produce unique pheromones to attract mates from their own species. Researchers also identified six new species and found that these butterflies evolve rapidly due to high rates of chromosomal rearrangement. They hope these findings will support future biodiversity and conservation research.

水母爆發核電廠需暫停

August 22, 2025

法國最大的核電廠近日因大量水母卡在冷卻系統泵內而需要暫時關閉。專家解釋因氣候變化使水母得以繁衍生息，而過度捕撈導致一些水母的捕食者（如吞拿魚）消失。另外亦有入侵物種——海月水母的影響，牠們於2020年首次在該地區被發現。

The largest nuclear plant in France temporarily shut down due to numerous jellyfish clogging the cooling system pumps. Experts explain that climate change allows jellyfish to thrive and reproduce, while overfishing removes some of their natural predators, such as tuna. In addition, the introduction of invasive species like the Asian moon jellyfish—first sighted in the area in 2020—has contributed to the problem.

農田圍欄影響野生動物

August 9, 2025

自2021年，不丹一直在擴大圍欄以防止野生動物進入農田，造成農作物損失，減輕與人類造成衝突。然而，從長遠來看，這些圍欄限制了野生動物的活動，影響了牠們的遷徙、分隔種群並造成了棲息地的破碎化；亞洲象、孟加拉虎和喜馬拉雅鬣羚等物種都受到影響。

Since 2021, Bhutan has been expanding fencing around farmland to prevent crop damage and livestock loss. However, in the long term, these fences restrict wildlife movements, affect migrations, isolate populations, and cause habitat fragmentation. Species such as Asian elephants, Bengal tigers, and Himalayan serow are particularly affected.
