An exploratory and empirical study of the hibernation phenomenon, one of the adaptive strategies used by a population of Atelerix algirus to adapt to seasonal conditions, is presented in this work. The research was carried out between 2011 and 2019. A total of 231 hedgehogs were captured and weighed in the El Kala National Park localities of Raml Souk, El Aioun, Berrihane, El Kala, and Bougous in northeastern Algeria. Localities are distinguished by their useful surface area (forests and farmland) and degree of urbanization. The findings highlight the significance of environmental temperature in the onset of hibernation in Algerian hedgehogs. Furthermore, like the European species, hibernation in Atelerix algirus is brief, lasting no more than two months. Monthly weight status analysis of captured hedgehogs revealed no significant difference in this parameter before and after the ostensible hibernation period, implying that hedgehogs do not fatten up and thus do not prepare for hibernation.
