What characteristic of roe deer populations reflects the heavy, early-life attrition?

Answer

A surprisingly low median age, perhaps only 3 to 4 years.

Because a high proportion of the population dies very young, the median age, representing the midpoint of the population's age distribution, remains low even though individuals can live much longer.
