Life history trade-offs in co-operative breeders
Co-operative breeders are an interesting case study for life history theory, with the apparent load-lightening effects of helpers granting reproductive individuals high levels of fecundity across unusually long lives. Yet, the high reproductive success of a select few females also creates intense competition for breeding rights. Through my meerkat work, I investigate the relative influence of helping versus competition in shaping individual life history trajectories, with particular emphasis upon sex differences in rates of ageing.
