Survivorship curve
…intermediate between Types I and III, where roughly constant mortality rate/survival probability is experienced regardless of age. Some birds and some lizards follow this pattern. Type III or convex curves have the greatest mortality (lowest age-specific survival) early in life, with relatively low rates of…
