Hematological data of Batrachuperus tibetanus

Intraspecific variation is a common phenomenon in nature, but to date, research on such variation in hematological traits of urodeles remains scarce. To compare intraspecific variation in hematological traits among populations, and explore whether snout-vent length (SVL) and body mass influence hematological traits, we analyzed hematological parameters and erythrocyte size in 58 mature Batrachuperus tibetanus specimens belonging to three populations (Xihe, Meixian and Taibai) in northwestern China. There were no sexual differences in any hematological trait for all populations. No hematological traits differed significantly between the Meixian and Taibai populations, but significantly lower values of erythrocyte count (RBC), hemoglobin (Hb), hematocrit (Hct), erythrocyte length (L), and erythrocyte area (A), as well as a significantly higher leukocyte count (WBC) were observed in the Xihe population compared with the other two. Linear regression analyses showed that significant relation...
