The residual reproductive value represents an organism's future reproduction through its investment in growth and survivorship.

Beyond its sexual and reproductive value, oxytocyin appears to be a fraternizing compound as well.

Let us consider the reproductive value of these offspring at the moment when this parental expenditure on their behalf has just ceased.

First, there is an inexorable decline in probability of an organism's existence, and, therefore, in what he terms "reproductive value."

The monogynous female is dominant over the males and has great reproductive value.

Females are not the only ones assessing their partner's reproductive value.

Females that lay larger and brighter eggs are in better condition and have greater reproductive value.

There is an increase in cannibalism when broods have low reproductive value.

Smaller broods that are still early in the development cycle have relatively low reproductive value and are more likely to be cannibalized.
