survivorship curve

Then they drew a "survivorship curve" based on the proportions of individuals that died during each life stage.

One example of a species that follows this type of survivorship curve is the Octopus.

Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table.

In mathematical statistics, the survival function is one specific form of survivorship curve and plays a basic part in survival analysis.

The survivorship curve of box turtles is therefore probably similar to that of other long-living turtles.

Their survivorship curve is known as type III because hatchlings endure high mortality rates, while adults thrive.

A survivorship curve is a graph showing the number or proportion of individuals surviving at each age for a given species or group (e.g. males/females).

D. edule exemplifies a Type III survivorship curve and clumped distributions.

Type I survivorship curves are characterized by high survival in early and middle life, followed by a rapid decline in survivorship in later life.

From this he could obtain survivorship curves for cohorts of leaves born in the same time period and record some of the causes of death or damage within the populations (Fig. 16.5).

There are three generalized types of survivorship curve, which are simply referred to as Type I, Type II and Type III curves.

Thus Van Valen (1973) applied the survivorship curve technique of population biologists to the study of extinction rates for numerous fossil taxa, and claimed to demonstrate a general approximation to linearity in his curves, which are cumulative frequency distributions of taxonomic durations with logarithmic ordinates.
