Data from: Reduced mitochondrial respiration in hybrid asexual lizards

The scarcity of asexual reproduction in vertebrates alludes to an inherent
cost. Several groups of asexual vertebrates exhibit lower endurance
capacity (a trait predominantly sourced by mitochondrial respiration)
compared to congeneric sexual species. Here we measure endurance capacity
in five species of Aspidoscelis lizards and examine mitochondrial
respiration between sexual and asexual species using
mitochondrial respirometry. Our results show reduced endurance capacity,
mitochondrial respiration, and phenotypic variability in asexual species
compared to parental sexual species along with a positive relationship
between endurance capacity and mitochondrial respiration. Results of lower
endurance capacity and lower mitochondrial respiration in asexual
Aspidoscelis are consistent with hypotheses involving mitonuclear
incompatibility. This repository includes files with DNA sequence
alignments, evolutionary relationships, mitochondrial respiration, and
endurance measurements for five species of whiptail lizards. Code used to
analyze the data in the context of the study is also included.
