It describes a thermal reaction norm of developmental rate to temperature and has two main parameters, lower temperature threshold and sum of degree-days. Until recently, these parameters have been considered constant within species. Here we study thermal reaction norms for egg development to temperature in two leaf beetle species. There is a significant variation of the lower temperature threshold and sum of degree-days among the offspring of different females of two leaf beetle species. A parthenogenetic population exhibits a notably lower level of this variation. Refs 42. Figs 3. Tables 4.</p> ER -
