Abstract: Closely-related species can exhibit similar thermal requirements despite inhabiting different environments. Hybrid species between them can exhibit a diversity of thermal requirements, or can be similar to parental species. In this study, we investigated thermal preference and efficiency in parthenogenetic Aspidoscelis cozumela complex lizards (A. cozumela, A. rodecki, A. maslini) and their parental species (A. angusticeps and A. deppii), to determine whether thermal preferences are conservative. We found that thermal preferences are similar among species and determined by phylogenetic relationships. Aspidoscelis deppii (paternal species), A. cozumela and A. maslinishowed similar thermal preferences, whereas A. rodecki was similar to the maternal species (A. angusticeps). These results suggest that thermal preferences of parthenogenetic lineages match with one of the parental species and are not restricted to one gender. These findings support the “frozen niche variation” hypothesis.
