种群比较

The nad4 sequences of six cestodes samples(MM11JT,TH29CS,TPW32CZ,TPW33CZ, TH45XX,TPW45) were obtained and their sequence length was 523bp.The six nad4 sequences comparison revealed that they separated into three population.

获得6个代表性样品(MM11JT，TH29CS，TPW32CZ，TPW33CZ，TH45XX，TPW45)的核苷酸序列，序列长度均为523bp，经核苷酸序列互对比较，结果显示它们存在三个种群，且其种间差异为2.1%～30.1%，比种内变异(2.2%)大。

The objectives of the present study was to examine sequence variation in a portion of the mitochondrial NADH dehydrogenase subunit 1 gene (pnad1) within and among Toxocara canis, T. cati, T. malaysiensis, T. vitulorum and Toxascaris leonina, and to study their systematics and population genetics.

本研究旨在对弓首属犬弓首蛔虫、猫弓首蛔虫、马来西亚弓首蛔虫、牛弓首蛔虫和狮弓属狮弓蛔虫线粒体DNA中烟酰胺脱氢酶亚基I（nad1）基因部分序列（pnad1）进行比较研究，分析它们之间的序列差异和种群遗传关系。

No significant seasonal differences were observed in plateau pikas aggressive and affiliative behaviors from either low or high density populations. Additionally, no significant differences existed between populations with different densities.

在高原鼠兔的社会行为中，亲昵行为和攻击行为强度在不同种群密度间比较均无显著差异；在同一密度条件下，亲昵行为和攻击行为强度也没有表现出明显的季节性变化。

For assessing impacts of Bt rice on the non-target insects, the population parameters of the white-backed planthopper, Sogatella furcifera fed on transgenic cry1Ab rice varieties KMD1 and KMD2 and their parent rice variety XS11 were assayed in the laboratory.

通过室内饲养实验及水稻氨基酸和碳、氮含量测定，比较研究了转cry1Ab水稻克螟稻(KMD1和KMD2)与其亲本秀水11对非靶标害虫白背飞虱种群增长的影响。

A pairwise comparison of paternity studies of bird populations in relation to genetic variability as determined by minisatellite band sharing coefficients among unrelated individuals was used to test the prediction that females should engage more frequently in extra pair copulations in populations with a greater amount of genetic variation.

小卫星共有谱带系数(minisatellitebandsharingcoefficient)可确定无亲源关系个体之间的遗传变异性，对与遗传变异性有关的雄性个体的父亲进行了成对比较以检验如下假说：在具有较多遗传变异的种群中，雌性个体更经常地进行配偶外交配。

Therefore, in this region, the E.

但是每年的种群数量都比较大。
