Summary Introduction

To review:

The selective pressure which influence an individual to be a helper instead of allowing it to involve in reproduction.

Introduction:

Social interactions play an important role in increasing the fitness of an individual and it can be either direct or indirect fitness. Direct fitness involves reproduction of an individual to have their own offspring whereas, indirect fitness involves nonreproductive or helping behavior of an individual. Inclusive fitness includes direct and indirect fitness where a helper increases the reproductive success of parents or relatives, which also helps to increase possibility of shared alleles to pass into next generations.

Many factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care. [Select] [Select] protogynous hermaphrodite continuous hermaphrodite protoandrous hermaphrodite
In an iteroparous species lifetime fitness is maximized at investment, while in semelparous species level of reproductive an intermediate maximal effort is exerted in a single reproductive event Maximal an intermediate effort is exerted in one of many reproductive events an intermediate minimal effort is exerted in a single reproductive event maximal an intermediate effort is exerted in a single reproductive event an intermediate maximal effort is exerted in one of many reproductive events
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.
