Key Concepts

Survivorship Curves

Survivorship curves are graphical representations that show the number or proportion of individuals from a birth cohort that survive to different ages. They are used in ecology and demography to understand mortality patterns and life history strategies within populations, illustrating how the likelihood of survival changes across the lifespan of a species.

Type I Survivorship Curve

Type I survivorship curves are characterized by high survival rates during early and middle life followed by a steep decline in survival in later years. This pattern indicates that most individuals survive to old age and then die at a relatively similar time, a pattern commonly observed in species that invest heavily in parental care and have fewer offspring, such as large mammals.

Type II Survivorship Curve

Type II survivorship curves indicate a relatively constant mortality rate throughout the life span of the organism. In this pattern, the chance of dying is nearly equal for individuals of any age, suggesting that mortality factors such as predation or disease affect the population uniformly over time.

Type III Survivorship Curve

Type III survivorship curves are marked by very high mortality rates in the early stages of life, with those few individuals that survive this early period experiencing relatively low mortality later on. This pattern is typical for species that produce a large number of offspring, many of which do not survive to adulthood, highlighting a strategy where high reproductive output compensates for high early mortality.
