Radio-tracking study reveals seasonal home ranges and survival in juvenile hedgehogs, indicating suburban habitats support overwinter success.

Key Points

To investigate the seasonal home ranges, first-year survival, body mass changes, and hibernation behavior of juvenile European hedgehogs inhabiting suburban environments.
Monitored N=35 juvenile European hedgehogs using radio tracking across their first year of life (September 2014 to July 2015) in suburban western Copenhagen, Denmark.
Estimated 95% minimum convex polygon (MCP) home range sizes across autumn and spring/summer seasons.
Tracked body mass dynamics before, during, and after hibernation alongside survival probabilities and hibernation onset timing.
Autumn 95% MCP home ranges were 1.33 ha (95% CI: 0.88–2.00) for males and 1.40 ha (95% CI: 0.84–2.32) for females; spring/summer ranges expanded to 6.54 ha (95% CI: 3.76–11.38) for males and 1.51 ha (95% CI: 0.63–3.63) for females.
Juvenile survival probabilities were 0.79 for males and 0.56 for females from September 2014 to July 2015.
Healthy juveniles consistently gained weight prior to winter and survived hibernation with minimal body mass loss, though an unusually mild autumn delayed hibernation entry by up to one month.
