With their round bodies, big ears, and cute name, pikas are often called the “real-life Pikachu.” Though often mistaken for rodents, pikas are actually close relatives of rabbits and hares. Pikas typically grow about to 20cm in length, with short limbs and no visible tail. They live in high-altitude regions across North America and Asia, where freezing temperatures and rocks define their world. Luckily, their dense fur helps them survive the cold in these extreme environments.
Pikas are known for their calls, which sound surprisingly loud for their size. Their calls resemble the high-pitched cry of a lamb, only much sharper and higher. These communications not only serve as warnings but also attract potential mates.
Beyond their vocal behavior, pikas impress scientists and nature-lovers with their lifestyle. Unlike hibernating animals, pikas remain active all year round. In summer, they collect and dry grasses, wildflowers and mosses as food to prepare for the harsh winter. This behavior ensures their survival and demonstrates their ability to adapt to environments with limited resources.

Unfortunately, climate change is making life harder for pikas. With thick fur and high body temperatures, they cannot tolerate heat exceeding 25oC. As global warming intensifies, their cool habitats are shrinking. Human interference further compounds these challenges. On the Tibetan Plateau, large pika groups are seen as pests that eat grass meant for livestock. In response, the Chinese government has implemented large-scale poisoning campaigns to control their numbers. Many wildlife experts worry about the long-term ecological impact of this practice.
Although pikas as a whole are not classified as endangered, many local populations are quietly disappearing, such as the Ili pika. Their story reminds us that species loss often begins without notice. Protecting them means acting before decline turns into disappearance. In doing so, we also preserve the delicate mountain habitats they live in.
鼠兔有著圓滾滾的身體、大大的耳朵和可愛的名字，常被稱為「真實版的皮卡丘」。雖然經常被誤認為是囓齒動物，但鼠兔實際上是兔子和野兔的近親。鼠兔的體長大約可達20公分，四肢短小且沒有明顯的尾巴。牠們生活在北美和亞洲的高海拔地區，那裡嚴寒的氣溫和岩石構成了牠們的世界。幸運的是，濃密的皮毛幫助牠們在極端環境中抵禦寒冷並生存下來。
鼠兔以其叫聲而聞名，相對於牠們的體型來說，叫聲響亮得令人驚訝。牠們的叫聲類似於小羊的尖銳叫聲，只是更銳利、更高亢。這些叫聲不僅可作為警告，還能吸引潛在的配偶。
除了聲音行為之外，鼠兔的生活方式也讓科學家和大自然愛好者印象深刻。和會冬眠的動物不同，鼠兔全年都很活躍。在夏季，牠們會採集並曬乾草、野花和苔蘚，作為寒冬時的糧食。這種行為確保了牠們的生存，也展現了牠們適應資源有限環境的能力。
不幸的是，氣候變遷正讓鼠兔的生存變得更加艱難。由於擁有厚實的皮毛和較高的體溫，牠們無法忍受超過攝氏 25 度的氣溫。隨著全球暖化加劇，牠們涼爽的棲息地正在縮小。人類的干預更使問題雪上加霜。在青藏高原，大群鼠兔被視為有害的動物，因為牠們會搶吃原本要留給牲畜食用的草。為此，中國政府實施了大規模的毒殺活動，以控制鼠兔的數量。許多野生動物專家擔心這樣的做法對生態環境的長期影響。
雖然鼠兔整體而言並未被列為瀕臨絕種的，但許多當地族群正在悄悄消失，例如伊犁鼠兔。牠們的故事提醒我們，物種滅絕往往在不知不覺中開始。保護牠們意味著在數量下降演變成滅絕之前採取行動。這樣做，我們也是在守護牠們賴以生存的脆弱山區棲息地。

A: The Danjiang Bridge in New Taipei City is to open on May 12, and the MRT Sanying Line (Light Blue Line) will also open in June. Isn’t that great? B: Is that the bridge connecting the city’s Tamsui and Bali Districts? What’s so special about this new landmark spanning the Tamsui River? A: The Danjiang Bridge will become the world’s longest-span single-mast asymmetric cable-stayed bridge — with a total river-crossing section of 920 meters and main span of 450 meters. B: The news says there are sidewalks and bike lanes on both sides. Watching the sunset from the
Few sea creatures of their size have as much destructive power as pistol shrimp. These small animals, usually measuring around four centimeters long, produce shock waves that can stun or even kill their prey. The attack begins when the shrimp opens its specialized claw, allowing water to fill a chamber inside. Then the claw closes rapidly. A bump on the claw strikes the chamber, forcing the trapped water out through a narrow opening at a high speed of about 25 meters per second. The rapid movement forms a bubble in the water that collapses almost instantly under the pressure of the
In the dense forests of Tanzania, a young researcher sat quietly among the trees, her gaze fixed on a troop of chimpanzees. It was 1960, and Jane Goodall, armed with nothing but a notebook and endless curiosity, was about to change science forever. Inspired by childhood stories like the Dr. Dolittle series, she had dreamed of Africa — and now, thanks to the encouragement of anthropologist Louis Leakey, she was there, face-to-face with the wild. What Jane discovered shocked the world. Chimpanzees weren’t mere creatures of instinct; they were individuals with emotions, families, and even the capacity for tool
