That senescence is rarely, if ever, observed in natural populations is an oft-quoted fallacy
within bio-gerontology. We identify the roots of this fallacy in the otherwise seminal works of …

According to recent empirical studies, reproductive senescence, the decline in reproductive
success with increasing age, seems to be nearly ubiquitous in the wild. However, a clear …

Ageing and sexual selection are intimately linked. There is by now compelling evidence
from studies performed across diverse organisms that males allocating resources to mating …

Sperm function generally declines with male age. Paradoxically, females of many species
still choose to mate with old males rather than young males. Females choosing old mates …

Empirical studies reveal aging occurs in wild populations. Consideration of the ecological
and evolutionary consequences of these findings is critical for many areas of research …

Variation in sperm traits is widely documented both at inter-and intraspecific level. However,
sperm traits vary also between ejaculates of the same male, due for example, to fluctuations …

Models of ageing predict that sperm function and fertility should decline with age as sperm
are exposed to free radical damage and mutation accumulation. However, theory also …

Recent studies of wild populations provide compelling evidence that survival and
reproduction decrease with age because of senescence, a decline in functional capacities at …

Older males often perform poorly under post-copulatory sexual selection. It is unclear,
however, whether reproductive senescence is because of male age itself or the …

Why do senescence rates of fitness-related traits often vary dramatically? By considering the
full aging trajectories of multiple traits, we can better understand how a species' life history …
