All of the following scenarios are examples of barriers that distinguish separate species. Which is not a post-zygotic barrier? * Two species of ladybugs live in the same habitat. Although they mate at the same time of year, their genitals are physically incompatible. Two species of fish inhabit the same stream. They are capable of mating and producing healthy offspring. The offspring, however, are infertile. Two species of opossums inhabit the same forest. Although they are capable of mating, no offspring ever survive development. Two species of mice coexist in a forest habitat. They are capable of mating and producing offspring. The offspring, however, are frail and die young.

Is the following case study an r-strategist or a K-strategist? American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.

In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.
Satellite and attached male horseshoe crabs do not have the same reproductive success. Why hasn’t sexual selection eliminated the low-payoff satellite option if males exercising this option do not leave as many descendants as attached males do? Please don't write from any online source.
