Ageing refers to the loss of organismal functionality with age, a process that is characterised
by decreased reproduction and survival probability. In natural populations, it is expected that …

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 …

Telomere length (TL) is considered an important biomarker of whole-organism health and
aging. Across humans and other vertebrates, short telomeres are associated with increased …

Telomere dynamics are linked with both cellular and organismal senescence, and life
history, individual quality and health. Telomere dynamics, particularly telomere length, have …

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 …

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 …

Telomere length and telomere shortening predict survival in many organisms. This raises
the question of the contribution of genetic and environmental effects to variation in these …

Telomeres, the nucleotide sequences that protect the ends of eukaryotic chromosomes,
shorten with each cell division and telomere loss may be influenced by environmental …

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 …

Understanding where genetic variation exists, and how it influences fitness within
populations is important from an evolutionary and conservation perspective. Signatures of …
