Giant Panda's Movement And Teeth Skeleton System Function Morphology Analyze And The Environment Problem It Reflects

As the proper wildness rarity animal, the habitats of panda take on fragmentized distribution on account of jamming, their populations distribut in Qinling of Shanxi, Minjiang of Sichuan, Qionglai Mountain, Daliang Mountain and Xiaoliang Mountain, dispersedly. Nature and man-made factors cause the difference of living condision, so populations are different at living behaviour and nourishment tactic in order to adapt circumstance during long anagenesis process conduce the representation. According to the oneness of conformation and function, investigate panda locomotion and bones syetem of tooth, integrating ecological character under the wild state, discussing pertinence between thenm in order to offer scientific gist for panda protection.Former investigate exhaustively describe bones of panda but tooth character correlation with eating habit limited in population age structure's ascertainment and investigate with pertinence between different population bones or tooth form and different bamboo sort eating is very little. This article analysis the pertinence form and entironment, vegetation, food etc. through contrast investigate on panda bones and tooth of geographical population Shanxi, Gansu, Sichuan in order to get new ingathering and validate Fang Guo-sheng's viewpoint about panda subspecies analysised by genetic order measure and bones analytical method.The content of the research include:(1)According to compare bones of population and modality of armature,to discuss the establishment of giant panda subspecies from the view of function morphologic by stat analysis based on subspecies form theory,(2)After measuring the anatomy characteristic of giant panda armature of differ population and differ age , The paper discuss the adaptability of giant panda to taking-food specialityalong with the study on giant panda taking-food ecology.1 According to main component analysis on the morphology measurement original data of giant panda,to filter avaiability index of main factors and merger,make it become the most main character factor:the first main factor represent the integer length and broad as well as the form variable of cheekboneof craniology.The second main factor represent the variable between Crista sagittalis groove and Skull basilar. The third main factor represent the length of Crista sagittalis,length of .The fourth main factor represent the Crista nuchalis variable.The fifth main factor represent the angle of Arcus zygomaticus and teeth row., palate length, upper neurocranium length.2 According to comparative analysis on the armature, the modality characteristic of craniology of giant panda with other area,the size of craniology holomorphy in Qinling and Minshan is near, Qionglai mountain's is bigger.The snout of giant panda in Qinling is shorter.the sizes of Minshan and Qionglai mountain are near longer.In the five variables , between Qinling and Minshan have three variables exist markedness difference, between Qinling and Qionglai mountain have five variables exist markedness difference, between Minshan and Qionglai mountain have four variables exist markedness difference.Based on above analysis , the size characteristic of snout of giant panda in Qinling has obvious distinguish with other mountain system.the size of morphology and other morphology classify characteristics have no obvious gap.The results indicate that the Qinling subspecies's existence, is short of sufficient evidence.3 The adaptability of giant panda armature to taking-food speciality represent that the increase of dentition.the augment of chaw area of premolar and cheek tooth as well as the aggrandizement of the exterior space between of zygomorphous dentition.4 The adaptability of giant panda morphology to taking-food speciality represent that upgrowth of crista sagittalis> crista nuchalis, the expanse of cheekbone,the thundering upgrowth of fossa temporalis,which so as to accommodate more chaw muscle , the granualte occipital surface can accrete mightiness muscle,the mandible is firmly and massiness.5 The form of hind legs skeleton of giant panda is shorter and thicker than black bear's collectivity.The black bear always climb precipitous slope, but the giant panda also choose gently country to move about restricted by bones form in certain . It is related to giant panda also adhibit squat posture that the girdle bone is expanse and firmly.
