Animal response to stressors such as harsh environmental conditions and demanding
biological processes requires energy generated through increased mitochondrial activity …

Sex differences in aging occur in many animal species, and they include sex differences in
lifespan, in the onset and progression of age‐associated decline, and in physiological and …

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 …

Social evolution is tightly linked to dispersal decisions, but the ecological and social factors
selecting for philopatry or dispersal often remain obscure. Elucidating selection mechanisms …

How can the stunning diversity of social systems and behaviours seen in nature be
explained? Drawing on social evolution theory, experimental evidence and studies …

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 …

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 …

Background The gut microbiome (GM) can influence many biological processes in the host,
impacting its health and survival, but the GM can also be influenced by the host's traits. In …

DNA methylation‐based biomarkers of ageing (epigenetic clocks) promise to lead to new
insights into evolutionary biology of ageing. Relatively little is known about how the natural …

Individual lifespans vary tremendously between and also within species, but the proximate
and ultimate causes of different ageing speeds are still not well understood. Sociality …
