Most research on mechanisms of aging is being conducted in a very limited number of
classical model species, ie, laboratory mouse (Mus musculus), rat (Rattus norvegicus …

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 …

Exceptionally long-lived species, including many bats, rarely show overt signs of aging,
making it difficult to determine why species differ in lifespan. Here, we use DNA methylation …

Various biological attributes associated with individual fitness in animals change predictably
over the lifespan of an organism. Therefore, the study of animal ecology and the work of …

Hibernation is linked with various hypotheses to explain the extended lifespan of hibernating
mammals compared with their non-hibernating counterparts. Studies on telomeres, markers …

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 …

Research on telomeres in the fields of ecology and evolution has been rapidly expanding
over the last two decades. This has resulted in the formulation of a multitude of, often name …

Although early‐life adversity has been associated with negative consequences during
adulthood, growing evidence shows that such adversity can also lead to subsequent stress …

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 …

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 …
