Calorimetric investigations of the pollination biology of the thermogenic inflorescences of the dragon lily (Dracunculus vulgaris) and its pollinator (Protaetia cretica) on Crete
This paper concerns thermometric and direct and indirect investigations of the heat produced by the thermogenic dragon lily (Dracunculus vulgaris) and its main pollinating beetle Protaetia (formerly named Potosia) cretica. The experiments were performed on scented and scentless populations at Panormo, Therisos and Lassithi on the North coast of Crete in the springs of 2007 and 2008. D. vulgaris in
