东北兔(Lepus mandshuricun Radde)野外种群三种年龄鉴定指标的比较

The comparision of three indexes to distinguish age of Manchurian Hare(Lepus mandshuricun Radde)population in field

东北兔各年龄组间体重、体长均有极显著差异,表明随年龄增长东北兔的体重、体长也相应增长.对不同年龄组的东北兔晶体质量与体重、体长做相关分析,结果表明,Ⅰ,Ⅱ,Ⅲ龄组的东北兔晶体质量与体重、体长之间相关非常显著,可以认为它们是同步增长的;Ⅳ龄组的东北兔晶体质量与体重、体长之间的相关不显著,可以认为它们不是同步增长的.

The body weight and the body length of each group Northeast Hare had more different,this indicated that the body weight and the body length of Northeast Hare increased with the increasing age.The results of the correlation analysis between lens weight and body weight and body length in each goup Northeast Hare showed that significant correlation in Ⅰ,Ⅱ,Ⅲ group.This suggested that these indexes increased synchronously.In groupⅣ,the correlation between lens weight and body weight of Northeast Hare were not significant,this suggested that these indexes increased non-synchronously.
