Animals living in seasonal environments experience regular changes in their climatic conditions. Ambient temperatures and humidity might vary considerably between the hot and cold season, leading to differences in food availability. During the cold season, when most energy is required for endogenous heat production, food availability is often at its lowest. Maintaining homeostasis is a necessity for endothermic animals to allow proper cell function, normal behaviour and reproduction (Martín, 2001). Among the endotherms, heterothermic animals switch between poikilothermic and homeothermic strategies to minimise their energy expenditures during times of low food or water availability, alterations in food quality or increased food competition (Blanco et al., 2018; Dausmann, 2014; Streicher et al., 2017; Vuarin and Henry, 2014).
