Instantaneous death rate

Nettet1. nov. 2024 · The rate of net change g is due to instantaneous mortality rate m (> 0) and per-capita instantaneous recruitment rate r (> 0), such that g = r − m. To describe mortality, from N0 to N s T during the period T, we employ Equation 1 with r = 0 for the submodel of a pure death process, thus m = ln ( N0 / N s T )/ T as Equation 2 in Table 1.
