帕米尔原鸽与信鸽的形态学性状相似性与差异性研究

Study on the Morphological Traits Similarities and Dissimilarities between the Pamir Rock Pigeons and the Domesticated Carriers

根据帕米尔原鸽21羽样本与信鸽30羽样本之间形态学性状定量分析,帕米尔原鸽与信鸽样本之间初级飞羽数量和初级飞羽长度(P≥0.098)及次级飞羽数量和次级飞羽长度(P≥0.114)、躯体长度(P=0.091)均尚未发生显著变化。较帕米尔原鸽,信鸽嘴峰长、嘴峰宽、鼻长、鼻宽、鼻高、喙长、喙宽、喙高、眼宽、眼高、头长、头宽、头深(P≤0.049)显著增长,尾羽数、尾羽长增长显著(P<0.001),跗长增长显著(P<0.001),体重增重显著(P<0.001)。根据42项形态学性状主成分分析,鼻宽、头长、鼻高、右尾羽长、喙宽、喙长和左尾羽长合计7项性状为主要贡献性状,人工驯养显著增加信鸽鼻、头、喙和尾羽的长度(P≤0.049)。

The morphological traits comparisons between the Pamir rock pigeon 21 samples and the domesticated carrier 30 samples are manifested the following.The primary remiges numbers and lengths vary insignificantly between the Pamir rock pigeon samples and the domesticated carriers samples,P≥0.098,the secondary remiges numbers and lengths vary insignificantly between two group samples,P≥0.114 and the body lengths vary insignificantly between two group samples,P≥0.091 as well.The culmen lengths,culmen widths,nasal widths,nasal depths,nasal lengths,beak lengths,beak widths,beak depths,eyeball heights,eyeball widths,head lengths,head widths and head depths increase significantly in rock pigeon samples,P≤0.049,the tail feather numbers and their lengths increase significantly in rock pigeon samples,P<0.001,tarsus length increase significantly in rock pigeon samples,P<0.001,biomass increase significantly in rock pigeon samples,P<0.001.According to the 42 morphological traits PCA analysis,in which 7 traits as nasal breadths,head lengths,nasal depths,right side tail lengths,beak widths,beak lengths and right side tail lengths prove the principal contributing factors,the results manifest that the carriers nasal size,beak size,head size and tail lengths increased significantly under domestication.
