BACKGROUND Whereas early studies of animal evolution focused principally on the
adaptations of different species to their physical environment, more recent studies have …

Patterns of ageing across the tree of life are much more diverse than previously thought. Yet,
we still do not adequately understand how, why and where across the tree of life a particular …

Age-related changes in fertility have increasingly been documented in wild animal
populations: In many species the youngest and oldest reproducers are disadvantaged …

Female reproductive health has been historically understudied and underfunded. Here, we
present the advantages of using a free-living nematode, Caenorhabditis elegans, as an …

A wave of studies has recently emphasized the influence of sex chromosomes on both
lifespan and actuarial senescence patterns across vertebrates and invertebrates. Basically …

Male reproductive traits such as ejaculate size and quality, are expected to decline with
advancing age due to senescence. It is however unclear whether this expectation is upheld …

Our understanding on how widespread reproductive senescence is in the wild and how the
onset and rate of reproductive senescence vary among species in relation to life histories …

Age‐specific fertility trajectories are fundamental to understanding population structure and
the evolutionary ecology of diverse life histories. However, characterizing reproductive …

Reproductive senescence is an age‐associated decline in reproductive performance, which
often arises as a trade‐off between current and future reproduction. Given that mortality is …

Reproduction is one of the most energetically demanding life-history stages. As a result,
breeding individuals often experience trade-offs, where energy is diverted away from …
