Using epigenetic clocks to investigate changes in the age structure of critically endangered Māui dolphins.

The age of an individual is an essential demographic parameter but is difficult to estimate without long-term monitoring or invasive sampling. Epigenetic approaches are increasingly used to age organisms, including nonmodel organisms such as cetaceans. Māui dolphins () are a critically endangered subspecies endemic to Aotearoa New Zealand, and the age structure of this population is important for informing conservation.
