对于有卵的物种或有幼崽的物种，导出了一个给出瞬时出生率的公式。结果表明，当卵子比例或怀孕率和发育时间已知时，可以计算瞬时出生率。将新方法与Edmondson和Caswell的早期方法进行了比较：后者错误地应用了Leslie的早期公式，而Edmondson的公式给出了有偏差的结果，偏差取决于开发时间的长短。
A formula giving the instantaneous birth rate is derived for egg bearing species or species which bear their young. It is shown that the instantaneous birth rate can be calculated when the egg ratio or pregnancy rate and the development time are known. The new method is compared with earlier ones by Edmondson and Caswell: the latter applies incorrectly an earlier formula by Leslie while Edmondson’s formula gives biased results, the bias depending on the length of the development time.
