Aging is a complex process that affects multiple organs. Modeling aging and age-related
diseases in the lab is challenging because classical vertebrate models have relatively long …

In many cooperatively breeding animal societies, breeders outlive non-breeding
subordinates, despite investing heavily in reproduction [1–3]. In eusocial insects, the …

Development of functional genomics tools has made it possible to define the aging process
by performing genome-wide scans for transcriptional differences between the young and the …

For several decades, senescence was considered as non-existing in free-ranging
mammalian populations simply because most animals were expected to die from …

Empirical evidence for declines in fitness components (survival and reproductive
performance) with age has recently accumulated in wild populations, highlighting that the …

Research on the physiological causes of senescence aim to identify common physiological
mechanisms that explain age-related declines in fitness across taxonomic groups …

Here, we review recent empirical advances that have improved our understanding of why
and when sex change occurs. We show that sex-changing animals use a greater diversity of …

The realization that senescence, age-dependent declines in survival and reproductive
performance [1–4], pervades natural populations has brought its evolutionary significance …

Reproductive senescence is a central and defining life‐history characteristic of every known
mammal. Within the scope of human senescence research, attention has been mainly …

Sex differences in lifespan are well recognized in the majority of animal species. For
example, in male versus female Drosophila melanogaster there are significant differences in …
