Senescence–the progressive age-dependent decline in performance–occurs in most
organisms. There is considerable variation in the onset and rate of senescence between …

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 …

Explaining variation in life expectancy between individuals of the same age is fundamental
to our understanding of population ecology and life history evolution. Variation in the length …

The degree to which changes in lifespan are coupled to changes in senescence in different
physiological systems and phenotypic traits is a central question in biogerontology. It is …

Helping by group members is predicted to lead to delayed senescence by affecting the trade-
off between current reproduction and future survival for dominant breeders. Here we …

In humans, gut microbiome (GM) differences are often correlated with, and sometimes
causally implicated in, ageing. However, it is unclear how these findings translate in wild …

Individual variation in telomere length is predictive of health and mortality risk across a
range of species. However, the relative influence of environmental and genetic variation on …

Several hypotheses have been put forward to explain the evolution of senescence. One of
the leading hypotheses, the disposable soma hypothesis, predicts a trade‐off, whereby early …

While life‐history theory predicts a tradeoff between reproduction and survival, positive
covariance, indicative of heterogeneity in individual quality, is often reported among …

In socially monogamous species, sexual selection not only depends on initial mate choice
but also mate switching. To date, studies lack assessment of (1) differences between …
