    Abstract:
    A model based on heat conduction and heat generation is used to predict temperature profiles in swarms. The model is applicable only at low values of the ambient temperature Ta. Guided by the experimental observations of Heinrich, the analysis is varied out mainly for non-spherical swarms. For Ta = 5 and 9°C, results based on a modified version of the heat generation function are in reasonable agreement with measurements. Results obtained with heat generation function of Myerscough are qualitatively similar with obtained with Southwick's function, but the error is more in the former case. The results suggest that the bees near the periphery generate more heat that those near the core, in accord with conjecture of Heinrich.
