Senescence in natural populations of animals: widespread evidence and its implications for bio-gerontology
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 …

Reproductive senescence: new perspectives in the wild
JF Lemaître, JM Gaillard - Biological Reviews, 2017 - Wiley Online Library
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 …

The hidden ageing costs of sperm competition
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 …

Are old males still good males and can females tell the difference? Do hidden advantages of mating with old males off‐set costs related to fertility, or are we missing …
SL Johnson, NJ Gemmell - Bioessays, 2012 - Wiley Online Library
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 …

Population biology of aging in the wild
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 …

Male sperm storage impairs sperm quality in the zebrafish
S Cattelan, C Gasparini - Scientific reports, 2021 - nature.com
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 …

Evidence that fertility trades off with early offspring fitness as males age
SL Johnson, S Zellhuber-McMillan… - … of the Royal …, 2018 - royalsocietypublishing.org
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 …

Parental age and lifespan influence offspring recruitment: a long-term study in a seabird
Recent studies of wild populations provide compelling evidence that survival and
reproduction decrease with age because of senescence, a decline in functional capacities at …

Male age alone predicts paternity success under sperm competition when effects of age and past mating effort are experimentally separated
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 …

Aging and Senescence across Reproductive Traits and Survival in Superb Fairy-Wrens (Malurus cyaneus)
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 …
