The type of survivorship curve obtained from the plot of the number of birds surviving with age from the data given in the table. Given: The number of female birds surviving to a particular age for a cohort is given in Table 1 below. Table 1: Number of female birds surviving to a particular age for a cohort. Year Age ( x ) Number of female birds (N x ) Survivorship (l x ) 2012 0 100 1 2013 1 50 0.5 2014 2 40 0.4 2015 3 30 0.3 Introduction: There are three types of survivorship curves. Type I survivorship curves are concave and these species have a high survivorship through their adulthood and a steep decline in old age. Species with a type II survivorship curve face a constant risk of death throughout their life. Type III survivorship curves are convex and such species have a high mortality rate early in their life and become stable on reaching maturity.
