Optimal body mass-length ratio during hibernation for Emys orbicularis (Linnaeus, 1758) - European Pond Turtle.

ABSTRACT: The aim of this study was to determine optimal body mass/length ratios of Emys orbicularis before hibernation. We obtained 213 measurements of wild-caught and captive-bred turtles during 9 years (2011-2019) and determined regression curves that show intervals for optimal or suboptimal body mass/length ratios before winter dormancy. Using this data we designed an online calculator that facilitates the process of establishing if a turtle has an optimal body mass/length ratio before hibernation. We also gathered 45 measurements at the end of the hibernation period which showed an average body mass loss of 5.32%. The present study offers practical means of assessing if an Emys orbicularis individual is fit for hibernation.
