In this study, some life history traits such as age  <span style="font-size:.9em;">structure, age at sexual maturity, lifespan, body size, head length and head width were tested for two different altitude populations of Ophisops elegans. The  </span> <span style="font-size:.9em;">results suggest that the individuals from the high altitude (Sivas, 1595 m) population have a higher mean body size and longer and wider head structure than the  </span> <span style="font-size:.9em;">low-altitude (Çanakkale, 7 m) population. Although, the mean age of the highland population was higher than the lowland population, this case was not found  </span> <span style="font-size:.9em;">statistically significant. In this study, both females and males were estimated to reach sexual maturity at an average of 3 years. The expected positive correlation  </span> <span style="font-size:.9em;">between age and body size was recorded for only females of the Çanakkale population. </span> </p>}, number={1}, publisher={Bülent VEREP}
