A method for investigating heat exchange in a honeybee winter cluster



A method for investigating heat exchange in a honeybee winter cluster



Doklady Vsesoyuznoi Akademii Sel' skokhozyaistvennykh Nauk im VI Lenina (4): 36-38



A theoretical analysis of heat transfer in the cluster shows that when air temperature decreases to between +5 and -10 deg C, the cluster contracts to reduce the heat exchange surface; the rate at which heat is given off remains almost constant. When the cluster can contract no further, any increased heat loss as a result of falling air temperature is compensated for by increased heat production in the colony.
