Both short photoperiod and communal social living conserve metabolic energy by deer mice held in thermal neutral ambient temperatures. Initial socialization was energetically more costly than solitary living, but huddling behaviors reduced thermal conductance and mass specific metabolic rate by 30% within 5 days. While short photoperiod reduced metabolic energy expenditure by decreasing thermoregulatory demand, huddling mediated behavioral conservation was achieved with hyperthermic core temperatures.
在热中性环境温度下饲养的鹿鼠，短光照周期和群居生活都能节省代谢能量。最初的社交活动在能量消耗上比独居生活更高，但聚堆行为在5天内使热传导和单位质量代谢率降低了30%。虽然短光照周期通过降低体温调节需求来减少代谢能量消耗，但聚堆介导的行为节能是在核心体温升高的情况下实现的。
