Survivorship and rK Strategies

Type II survivorship curve implies:

“Constant mortality throughout life” for type ii survivorship curve implies. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Selection favors the schedule that increases lifetime reproductive success under local mortality and resource conditions. Body size, development time, fecundity, parental investment, and generation length consequently tend to covary. The remaining alternatives—“High early life survival”, “Steep late-life mortality”, “Irregular death patterns”—refer to different states, proce

A population grows slowly and stabilizes at K. Which survivorship curve fits?

“Type I” for a population grows slowly and stabilizes at k. which survivorship curve fits. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Selection favors the schedule that increases lifetime reproductive success under local mortality and resource conditions. Body size, development time, fecundity, parental investment, and generation length consequently tend to covary. The remaining alternatives—“Type II”, “Type III”, “Logistic”—refer to different states, processes, or scales and therefore do not
