No Evidence That Life History Strategies Shape Within-Body Mosaics of Ageing.

ABSTRACT: Tissues across the body may age at different rates, which creates within-body mosaic ageing. Life history strategies shape ageing patterns at the inter- and intra-specific level, but the impact of life history strategies on mosaic-ageing patterns within individuals remains unknown. Reproductive tissues in individuals selected to prioritise reproduction may age faster than somatic tissues because of increased 'wear and tear'. Alternatively, individuals that prioritise reproduction may specially protect reproductive tissues at the expense of somatic tissues to allow for increased reproductive function. Here, we used Japanese quail (Coturnix japonica) artificially selected for increased versus reduced reproductive investment (egg size) to test how reproductive strategies modulate within-body
