Fig. 2 in Individual Growth Rates of Nikolsky's Viper, Vipera berus nikolskii (Squamata, Viperidae)
Fig. 2. Individual growth curves of males and females of V. b. nikolskii approximated with the Von Bertalanffy growth curves. Solid lines connect observed SVL of recaptured specimens. Dashed lines represent the Von Bertalanffy growth curve. Horizontal solid line is the size of maturation. X-axis measures time in days, hibernations are indicated by numbers. The duration of active period before first hibernation was assumed to be 45 days; all consecutive active periods lasted 184 days, except for 164 days in adult males.
