Observations

Field studies have failed to find statistical differences between the mortality rates and reproductive outputs of young and old painted turtles [0006]. As such, this has been considered a species with negligible senescence. However, in one study on >1000 wild painted turtles successful reproduction and survival declined with age in females. Despite high reproductive output, the produced eggs had reduced hatching success. These findings were attributed to possible human disruption [1187].
