暖化,生態影響

摘要或動機

此研究是探討在目前全球因聖嬰現象後北極暖化,造成溫度持續在三十年內以每年上升攝氏零點五度,目前多數資料以顯示,對於地球內的生物生態產生了微妙的變化,在本文中將引述著名雜誌─科學人雜誌所刊登之關於全球暖化造成的生態環境影響;然而早在三億五千萬年前就已存在地球上的古老生物─蟑螂,順利的度過了多次的大滅絕,走過冥霜與煉獄。但是否會因為暖化作用而造成其生態影響呢?他又會不會成為少數存留並且大量繁殖的征服者呢?所以我們開始查詢白堊紀之資料,在研究、討論並製作改造完成實驗室氣溫控制冷熱溫差調節器,並從專業研究蟑螂生態的業界專業實驗室取得同一時期的實驗蟑螂物種,以期待本實驗更能具有更高的正確可信度;於特殊自行改造的觀察箱內進行整個實驗,已改變溫度並測量其進食狀況,瞭解蟑螂在溫度變化下的生態狀況。\r

It’s easy to find the cockroach at any corner, such as school or house. They also hide in the refrigerator and stove.Thus,we are curious why they have durable vitality. This is the reason why we want to uncover the mysterious veil. According to data, we are curious about the environment of the cockroach and the temperature.Therefore,we want to imitate the situation of the ecosystem temperature at that time and inquire into its mystery. The purpose of Research is to make the violent changes, then discussing the meal which has attained its biggest existence rate. This uncontrolled experiment will influence the accuracy by factors.Therefore,we go to visit the laboratory personally and obtain some species of cockroach. Through the professional explanation and introductions, we make sure the direction of this experiment further. In this experiment we measure their appetite and the controls of the temperature everyday. They almost can crawl quickly along any material. We adopt the professional suggestion to measure with CO2 and O2.When the cockroach inhales CO2,we can observe the construction of the each part carefully. Through long-term observation, the food of the cockroach decreases, when the temperature rises to 20.6℃ or declines to 16.3℃,and it will stop moving when the temperature rises to 31.8℃ or declines to 8.7℃. When the temperature rises rapidly or reduce more than 15℃,the cockroach will look for shelter. Besides they easily get fainted when cockroach inhales CO2 without soil. The dinosaur were all buried underground, but why can the cockroach survive up to now? Probably, large land is their savior! Our conclusion is (1)The temperature that cockroach can exist from 49℃ to 3℃.(2)The suitable environment of cockroach growth is between 28.5℃ and 25℃.(3)The cockroach maintains their existence by eating under the low temperature 20℃ to 15 ℃.(4)Above 32℃ and under 7℃ the antenna is close to ground, its life is weaker.(5)The cockroach almost can live at any dilemma. But it can’t keep the prosperous life when it’s short of water.(6)From the above cockroach will be king of the world forever.
