English term or phrase: take each day that the male was alive
I then created a simple index of male breeding opportunities by taking each day that the male was alive and discounting his likelihood of breeding by the number of ripe females in the population per male on that day, and summing this over his lifespan.

是怎样一个公式?

计算方式如下


Explanation:
举个例子:假设某一天内,在观察范围之内,一共有3尾成熟的雌鱼和5尾雄鱼,在该天来说,每一条雄鱼的繁殖机会{likelihood of breeding}就被假设为五分之三。如此类推,把受观察雄鱼每一天在生的繁殖机会{likelihood of breeding}加起来{summing this over his lifespan},就可以达到笔者所要求的目的:simple index of male breeding opportunities .......

回应:一天是一个整数,再用上面“三尾雌鱼可供五尾雄鱼交配”的例子,当天的概率就该由“一”{discount}到五分之三,这个从“一”调为五分之三的运算,就叫做{discount}。

理解如下


Explanation:
这里计算的是雄性的繁殖机会,他的指标考虑了雄性生命周期的每一天。雄性某一天的生殖机会为当日在整个群体中雄性平均可以交配到的成熟雌性数,也就是说这一天中,一个雄性可以分配到多少个成熟雌性。既然他用的是discount, 说明不到一个,小于1。

那么雄性生命周期的每一天都如是计算/统计,得出的所有数字一平均,就是雄性繁殖的机会。
