Age-dependent changes in cuticular color and pteridine levels in a clonal ant

Hartmann, Clara ; Heinze, Jürgen ; Bernadou, Abel


Social insects are emerging models for studying aging and the longevity/fecundity trade-off. Research on the demography of colonies and populations are hampered by the lack of reliable age markers. Here we investigate the suitability of cuticular pigmentation and pteridine fluorescence for age grading individuals of the clonal ant Platythyrea punctata. We found that both traits varied with age. ...
