(A) Dynamics of serum testosterone concentration in the group of hedgehogs (n = 7) obtained in the period from May 22 to June 3, 2018. Blood samples were taken from 7:40 to 8:50. (B) Distribution of all obtained data of testosterone concentration by days of the 4-day period. The first day of the 4-day period included getting data on May 22, 26, 30 and June 3; the second, on May 23, 27 and 31; the third, on May 24 and 28 and June 1 and the fourth, on May 25 and 29 and June 2. The concentrations of testosterone in acrophase (the 2nd day) and bathyphase (the 4th day) were significantly different between each other, p = 0.027.
