黑线姬鼠形态特征变化规律

为掌握黑线姬鼠不同性别、不同年龄组、不同季节、不同生境形态特征的变化规律。对贵州省播州区2016—2022年捕获的1040只黑线姬鼠不同性别、不同年龄组、不同季节、不同生境的形态特征进行统计分析。结果表明：黑线姬鼠平均体重为(28.85±6.09)g，平均胴体重为(20.65±4.46)g，平均体长为(93.49±9.70)mm，平均尾长为(72.01±9.43)mm，平均后足长为(19.13±1.50)mm，平均耳高为(10.86±2.37)mm。不同性别形态特征的差异极显著，不同年龄组之间形态特征差异极显著，随着年龄的不断增长而不断增加，不同季节形态特征存在一定差异，旱作区各项形态指标均高于稻田区。

Changes of morphological characteristics of Apodemus agrarius

In order to master the morphological changes of Apodemus agrarius in different sexes, different age groups, different seasons and different habitats. The morphological characteristics of 1040 A.agrarius captured in Bozhou District of Guizhou Province from 2016 to 2022 were statistically analyzed in different sexes, different age groups, different seasons and different habitats. The results showed that the average body weight of A. agrarius was (28.85± 6.09) g, the average carcass weight was (20.65 ±4.46) g, the average body length was (93.49±9.70)mm, the average tail length was (72.01±9.43)mm, and the average hind foot length was (19.13±1.50) mm. The difference of morphological characteristics between different genders is extremely significant, and the difference of morphological characteristics between different age groups is extremely significant, which increases with the increase of age. There are certain differences in morphological characteristics in different seasons. The morphological indicators in dry farming areas are higher than those in paddy fields.
