Hibernation provides a means of escaping the metabolic challenges associated with seasonality, yet the ability of mammals to prolong or re-enter seasonal dormancy in response to extreme weather events is unclear. Here, we show that arctic ground squirrels in northern Alaska exhibited sex-dependent p...

Hibernation provides a means of escaping the metabolic challenges associated with seasonality, yet the ability of mammals to prolong or re-enter seasonal dormancy in response to extreme weather events is unclear.

Females and non-reproductive males responded to the >1 month delay in snow-melt by extending heterothermy or re-entering hibernation after several days of euthermy, leading to a >2-week delay in reproduction compared to surrounding years.
