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 …

Following the discoveries of telomeres and of their implications in terms of health and
ageing, there has been a growing interest into the study of telomere dynamics in wild …

Background The vertebrate gut microbiome (GM) can vary substantially across individuals
within the same natural population. Although there is evidence linking the GM to health in …

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 …

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 …

Wild animals experience different challenges and opportunities as they mature, and this
variety of experiences can lead to different levels of welfare characterizing the day‐to‐day …

Telomeres have been advocated to be important markers of biological age in evolutionary
and ecological studies. Telomeres usually shorten with age and shortening is frequently …

Oxidative damage is predicted to be a mediator of trade-offs between current reproduction
and future reproduction or survival, but most studies fail to support such predictions. We …
