關於河馬的寓言故事：我與河馬The Hippo and IA hippo lives in the zoo. I like him very much. I often go to see him. He often thinks of me, too. Today is Sunday. It is fine day. I go to see him again. After I leave the zoo, he follows me to my house. I give him lettuce, cabbages, bananas, apples and other food. He eats them up. When I sing songs, he stays in the pool. He is as quite as a rabbit.
In the evening, he jumps onto my bed with me. My mum tells him to go home. He has to pack his bag and go back to the zoo. My mum lets me see him every week.
河馬住在動物園裏，我很喜歡他。他經常去看它，他也經常想我。
今天是星期日，是個好天氣，我又一次去看望它。在我離開動物園之後，他跟隨到我的家。我給他萵苣、生菜、香蕉、蘋果和其他食物。他都吃了。
當我唱歌是，它待在水池裏，像兔子一樣安靜。
晚上，他跳到牀上同我睡覺在一起睡。
媽媽要它回家。它不得不背起包回到動物園。媽媽允許我每週去看它。
關於河馬的英文閱讀：河馬對生態系統的意義A new study says the hippopotamus is very important to the health of Africa’s rivers and lakes. That’s because hippos produce a key ingredient for aquatic life -- and a lot of it. But researchers warn that hippo populations are on the decline and that could damage ecosystems.
The mighty hippopotamus is the third largest land mammal following the elephant and rhinoceros. Its name is derived from the ancient Greek for river horse. Hippos spend up to 16 hours a day in the water and venture on to land at night to feed. They eat tropical grasses, more than 200 kilograms per meal. And what goes in must come out. And there is the magic ingredient for Africa’s aquatic ecosystems – dung.
Douglas McCauley and his colleagues decided to study it.
“Well, we started looking at hippopotamus and realized that a big part of the story was their poop – was this vast amount of nutrients and energy that are moved across systems via their eating and their defecation,” he said.
McCauley is an assistant professor of ecology, evolution and marine biology at the University of California Santa Barbara. He said hippos cross the boundaries of ecosystems.
“Transiting between two different domains – between land, the terrestrial world, and then the aquatic world – means that there are also these important nutrient vectors. Because their eating lots and lots of stuff on land and then taking that all back to the place where they rest in the water -- in lakes and rivers -- and then basically dunging that all out. And it turns out when you start crunching the numbers to be a huge amount of material and energy and nutrients of this sort of natural fertilizer that is moved across these boundaries,” he said.
So, each hippo contributes, if you will, over 60,000 kilograms of dung to African lakes and rivers every year.
“It’s a big animal,” he said, “We’re talking about an animal that’s about 4,000 to 8,000 pounds. So, it’s got a big appetite. When you look across the entire continent and our estimate of how many hippos we now have in sub-Saharan Africa that comes out to millions of kilograms.”
So, by now you understand it’s a tremendous amount of dung. But did you know that hippo dung looks like straw?
“That’s right. So, they are mostly feeding on grass, sort of a straw-like grass. In fact, a lot of African grasses are used as straw and forage for cattle in places like America. So, they have these wonderfully well-developed lips that they use like a lawnmower to go across these short grass lawns that they actually manicure. And they keep them short because it seems to keep this resource accessible just to them,” said McCauley.
McCauley said it’s even used as a communication device.
“They actually use dung as a kind of signal amongst themselves. So, a male animal will dung at a sub-dominant male. They actually fling it back and forth with their paddle-like tail.”
But the really important thing about hippo dung is its place in the food chain.
“Well, there’s a lot of good stuff in dung. There’s a lot of nitrogen, carbon, even a bit of phosphorus. And some of these nutrients can be limiting in river systems. These are sort of the building blocks of life in some cases. So it really is injecting more of this food into these rivers. And a lot of the animals it seems in the rivers are quite happy to receive it. Some of them eat it up directly and some consumers, like fish, will eat insects that started their lives feeding on dung,” he said.
McCauley actually described it as a life force in Africa’s rivers and lakes. But he said if the water flow is too low, the dung could overwhelm the ecosystem and be a pollutant. Too much water and its value is diluted.
But as researchers learn more about the importance of hippos, there are fewer of them.
“Hippos are declining across sub-Saharan Africa. In the past decade or so, we’ve seen about a 10 to 20 percent decline in their numbers. And beyond how many there are they’re in a lot fewer places. There are entire countries that have completely lost hippopotamus -- Egypt, for example. Hippos used to be an iconic god. It was the god of birth in Egypt. You see the hippo god. It’s a goddess turning up on amulets and wands and swords,” he said.
McCauley said humans are responsible for most of the decline in the hippo population through hunting and habitat loss as human populations spread.
“They have to have water. Well, guess what? Everybody else wants water. And it’s really unfortunate if you’ve tied your fate to water because when you compete with humans for water you often lose. So, people want water from rivers and lakes for building out cities – for helping to cool turbines– or damming rivers,” he said.
It’s estimated hippos kill about 3,000 people a year. The animals may attack, for example, if people get too near a mother and calf.
McCauley said careful thought must be given to the management of water, both for humans and wildlife. He says if managed intelligently, there should be plenty of water to go around, adding that the fates of humans, wildlife and ecosystems are closely tied together.
The study appeared in the journal Ecosphere.
一項新研究表明河馬對於非洲河流湖泊的健康來說很重要，這是因爲河馬能爲水生物製造大量的關鍵物質。但研究者警告稱河馬的數量正在下降，這將有損生態系統。
龐大的河馬是僅次於大象和犀牛的第三大陸生哺乳動物，其名字來源於古代希臘的河馬。河馬一天要在水中16小時，然後晚上冒險上岸覓食。它們吃大量的熱帶雜草，每頓要吃200多公斤。吃下去就要排泄，這就是非洲水生態系統中的神奇成分—糞便。
道格拉斯·麥考利和同事們決定研究河馬的糞便。
“我們研究河馬時意識到它們的糞便非常重要，有大量的營養物質和能量通過它們的飲食和排泄來在生態系統內循環。”
麥考利是加州大學聖巴巴拉校區生態、演化和海洋生物學助理教授，他說河馬參與了不同的生態系統。
“河馬在兩個不同的領域—陸上和水中進行活動，這意味這些重要的營養物質也在水陸之間傳輸，因爲它們吃大量的陸上食物，然後在水中休息時帶到水中，基本上是在河水和湖中將糞便排泄出來。所以如果進行計算，就會發現這種天然糞便中有非常大體量的物質、能量和營養物質在不同的系統間運輸。”
所以，每頭河馬每年向非洲的河流湖泊中排泄超過6萬公斤的糞便。
“這種動物很龐大，有4000到8000磅，所以它們胃口很大。所以着眼於整個非洲大陸，我們估計現在撒哈拉南部非洲的河馬能製造數百萬公民的糞便。”
這樣現在你就明白這些糞便有多少了，但你知道嗎?河馬的糞便看上去很像乾草嗎?
“那就對了，河馬主要以雜草爲生，有點像乾草的那種草。事實上，美國等地方會使用很多非洲雜草做爲乾草和飼料。所以，它們的嘴脣很發達，在吃短草坪時很像除草機那樣修剪雜草，它們讓雜草保持啃得很短，因爲似乎只有它們自己能吃到這麼短的草。”
麥考利說河馬甚至使用糞便來作爲通訊工具。
“它們使用糞便作爲自己族羣中的信號，所以，一頭雄河馬會在地位低的雄河馬身上排便，它們會用船槳似的尾巴把糞便拋來拋去。”
但河馬糞便真正重要的意義在於其在食物鏈中的地位。
“糞便裏有很多好東西，有大量的氮、碳、甚至還有磷，一些營養物質在河流系統中很有限，在一些情況下它們是構成生命的元素。所以河馬是在向河流排出大量的食物，而且似乎河中的很多動物都很喜歡這些糞便，有的動物直接吃糞便，像魚類這樣的捕食者會以食用糞便的昆蟲爲生。”
麥考利稱河馬糞便是非洲河流湖泊的生命物質，但他說如果河水流動太慢，糞便就會破壞生態系統，就成了污染物質，如果水太多，糞便的價值就會被稀釋。
但就在研究者對河馬的重要性有更多瞭解時，河馬的數量卻在減少。
“整個撒哈拉南部非洲的河馬數量都在減少，在過去10來年間，我們看到河馬數量減少了10%到20%。除了整體數量減少外，它們的棲息地數量也在減少。有的國家已經完全沒有了河馬，比如埃及。河馬過去被當做偶像崇拜的神，在埃及河馬是出生之神，你能看到有河馬神，護身符、權杖和刀劍上都有這種女神。”
麥考利說人類要對河馬數量減少負很大責任，隨着人口的流動，人類的狩獵和佔領棲息地導致河馬減少。
“河馬一定得有水，你猜怎麼着?大家都需要水，如果你的命運與水有關，那就很不幸，因爲你跟人類競爭時通常會輸。人們想獲得河流湖泊裏的水來建造城市，來冷卻渦輪或在河流上築壩。”
據估計河馬每年導致大約3000人喪生，比如，如果人距離母河馬和河馬幼崽太近，人類就會被襲擊。
麥考利說必須認真管理水，無論是爲人類還是爲野生物。他說如果管理得當，應該有大量的水可供使用，因爲人類、野生物和生態系統的命運是密切關聯的。
