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

Climate change is forecasted to generate a range of evolutionary changes and plastic
responses. One important aspect of avian responses to climate change is how weather …

Why and how we age are 2 intertwined questions that have fascinated scientists for many
decades. However, attempts to answer these questions remain compartmentalized …

Williams' evolutionary theory of senescence based on antagonistic pleiotropy has become a
landmark in evolutionary biology, and more recently in biogerontology and evolutionary …

What determines variation between individuals in how they senesce, and are environmental
conditions experienced during development relevant to late-life performance? We report a …

Understanding individual‐level variation in response to the environment is fundamental to
understanding life‐history evolution and population dynamics. Telomeres, the protective …

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 …

In most mammals, both sexes display different survival patterns, often involving faster
senescence in males. Being under intense sexual competition to secure mating …

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 …
