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 …

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 …

Aging, for virtually all life, is inescapable. However, within populations, biological aging rates
vary. Understanding sources of variation in this process is central to understanding the …

The distribution of age classes is a key demographic parameter of populations and thus
proper age estimation is crucial for fisheries management and for conservation biology. Age …

Age‐based demography is fundamental to management of wild fish populations. Age
estimates for individuals can determine rates of change in key life‐history parameters such …

Age‐related changes in DNA methylation do occur. Taking advantage of this, mammalian
and avian epigenetic clocks have been constructed to predict age. In fish, studies on age …

Age is a fundamental life history attribute that is used to understand the dynamics of wild
animal populations. Unfortunately, most animals do not have a practical or nonlethal method …

Biological ageing and its mechanistic underpinnings are of immense biomedical and
ecological significance. Ageing involves the decline of diverse biological functions and …

Abstract Changes in DNA methylation at specific CpG sites have been used to build
predictive models to estimate animal age, predominantly in mammals. Little testing for this …

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 …
