How long do we live? How long do individuals in other species live? Do most individuals die young or live to ripe old ages? Survivorship curves visually answer these demographic questions. Imagine a ...

The species survivorship curve for Cenozoic planktonic foraminifera was fitted to exponential (age-independent) and Weibull (age-dependent) models. Model fits that account for censorship bias have ...

Taxonomic survivorship curves may reflect stratigraphic as well as biologic factors. The approximately lognormal distribution of lengths of Phanerozoic time intervals ...
