Fertility of the European Brown Hare Across Plain, Hill and Mountain Environments in the Italian Peninsula

Abstract

This study examines the reproductive performance of the European brown hare in Italy, focusing on four hunting districts in Basilicata (A1, A2) and Emilia–Romagna (A3, A4) and using the number of endometrial scars as a fertility indicator. Fertility, measured as the number of scars during the entire reproductive period, was highest in A1 (11.50 ± 1.64) and A4 (11.43 ± 1.01), followed by A3 (9.56 ± 1.09) and A2 (6.08 ± 1.34). Significant differences were found when comparing the mountain area (A2) with A4 (p p r = 0.532; p = 0.036) between the Kerner Oceanity Index (with values of 16.87, 15.00, 8.45, and 11.11 in A1, A2, A3, and A4, respectively) and the number of scars per pregnancy across the four study areas. Understanding species’ reproductive dynamics is vital for assessing habitat suitability and creating strategies to sustain hare populations and their ecosystem roles.
