4种生态类群中10种鸟消化系统的形态学比较

本文从生态类群角度,对游禽(绿头鸭、秋沙鸭、鹊鸭、斑嘴鸭)、鸣禽(红尾伯劳、白头鹀、白眉鹀)、猛禽(雕鸮、金雕)和涉禽(苍鹭)这4种生态类群中10种鸟的消化系统形态结构进行了比较分析.研究获得各项基础数据,通过比较表明,4种生态类群10种鸟类消化系统形态多处存在明显差异.对于不同生态类群的鸟类来说,食性、食物的质量及活动特点等是影响消化系统形态的重要因素.

Morphological Comparison of the Digestive Systems from 10 Species of Birds in 4 Kinds of Ecological Groups

The digestive systems from 10 species of birds in 4 kinds of ecological groups were compared mophologically.The four groups were swimming birds(Anas platyrhynchos,Mergus merganser,Bucephala clangula,Anas poecilorhyncha),song birds(Lanius cristatus,Emberiza leucicephala,Emberiza laucocephala),birds of prey(Bubo bubo,Aguila chrysaetos),and wading birds(Ardea einerea),There are a number of significant differences in morphology between the digestive systems of these birds.Feeding habits,the quality of food and ...
