美國(guó)dpowerslab鳥類能量代謝研究案例

開放式呼吸計(jì)（open-flow respirometry）是測(cè)量生物能量代謝比較常用的方法，受到世界各國(guó)動(dòng)物生理生態(tài)學(xué)、生物醫(yī)學(xué)等領(lǐng)域科學(xué)家的長(zhǎng)久青睞。

北京易科泰生態(tài)技術(shù)有限公司代理的美國(guó)Sable Systems International品牌是世界上專業(yè)的動(dòng)物能量代謝測(cè)量技術(shù)公司，其產(chǎn)品以高靈敏度、高分辨率等性能應(yīng)用于很多特殊呼吸模式的野生動(dòng)物、各種實(shí)驗(yàn)動(dòng)物及經(jīng)濟(jì)動(dòng)物等生物，如具有間歇式呼吸的昆蟲、爆發(fā)式呼吸的潛水動(dòng)物、特定行為代謝的野生及實(shí)驗(yàn)動(dòng)物等，并有大量的研究文獻(xiàn)及實(shí)驗(yàn)方法、案例供參考。

本案例僅以美國(guó)喬治�？怂勾髮W(xué)知名的動(dòng)物能量學(xué)實(shí)驗(yàn)室Powers Research Lab ~ Studies in Animal Energetics (http://www.dpowerslab.com/) 研究蜂鳥、蛇及蜥蜴為案例介紹動(dòng)物能量學(xué)測(cè)量技術(shù)，包括針對(duì)不同的研究動(dòng)物，選擇不同的SSI呼吸代謝監(jiān)測(cè)模塊，以及特殊呼吸室的制作。

蜂鳥是世界上最小的鳥，體重甚至不足2克，能夠通過(guò)快速拍打翅膀而懸停在空中，也是是唯一可以向后飛的鳥。為維持極速飛行、上下翻飛、高速俯沖等日常活動(dòng)，蜂鳥的能量消耗及食物利用效率是非常驚人的。

作為動(dòng)物能量學(xué)研究特別是蜂鳥代謝研究的權(quán)威機(jī)構(gòu)，dpowerslab實(shí)驗(yàn)室選購(gòu)了不同的SSI動(dòng)物呼吸代謝監(jiān)測(cè)系統(tǒng)以滿足不同動(dòng)物研究的需要，如FOXBOX-C便攜式氣體分析儀，可直接帶到野外測(cè)量動(dòng)物的代謝率；Field Metabolic Systems便攜式動(dòng)物代謝儀，可監(jiān)測(cè)動(dòng)物能量代謝及水代謝；SSI模塊式動(dòng)物呼吸代謝測(cè)量系統(tǒng)，可根據(jù)研究目的，選擇不同的差分式氧氣分析儀、高靈敏度及分辨率的溫度檢測(cè)儀等模塊，研究動(dòng)物在不同行為狀態(tài)時(shí)的能量消耗。呼吸室的靈活性選擇使得SSI便攜式、模塊化代謝測(cè)量系統(tǒng)可以研究從單只果蠅到大型鯨魚的能量學(xué)研究。

以下為dpowerslab實(shí)驗(yàn)室用于蜂鳥、蛇類及蜥蜴的SSI便攜式及模塊式動(dòng)物代謝測(cè)量系統(tǒng)的圖片展示：
