Abstract
The inability to capture the age structure of a population using non-invasive faecal sampling has limited the scope of genetic analyses for wildlife research and conservation efforts. To overcome this, faecal morphometrics were examined to determine if differences exist between faeces size and the age of the individual producing it. Using faeces from known age caribou, pellet length distinguished calf and yearling age-classes from adult animals. Pellet width could only discern the calf age-class. Although this data is both area and species specific, gathering baseline data from known age animals prior to non-invasive collections may generate similar results and is recommended.
