Abstract—

The variability of craniological characters has been studied for anadromous and lacustrine forms of whitefish Coregonus lavaretus (Linnaeus, 1758) from waterbodies of the Karelian coast of the White Sea. The significant phenotypic plasticity of craniological characters of the whitefish depends on the environmental conditions. Moreover, there is a correlation between indexes of the craniological traits (except for the index of the snout length) and the body and/or head length (allometric effect). These results suggest that it is unreasonable to separate anadromous and lacustrine forms of C. lavaretus as distinct taxonomical units and argues for the invalidity of C. pidschian and C. oxyrinchus species.

白鲑Coregonus lavaretus（Linnaeus，1758）的反形态和湖相形式的表型可塑性和动物学特征的变种，表明了Coregonus pidschian的错误物种状态

摘要-

从白海卡累利阿海岸的水体中研究了白水鱼的无性和湖相形式的颅骨特征的变异性（Linnaeus，1758年）。白鱼颅骨特征的显着表型可塑性取决于环境条件。此外，颅骨性状的指标（鼻子长度的指标除外）与身体和/或头部的长度（异味效应）之间存在相关性。这些结果表明，这是不合理的分离的溯河和湖形式C. lavaretus作为不同的分类学单元和主张的无效C. pidschian和C. oxyrinchus物种。
