Mating fiddler crabs use several types of sexual selection. males battle each other for territory using their greatly enlarged claws. the territories preferred by females are those in the most physiologically stressful area, and only healthy males can maintain them for long. the males also raise their claws to signal females; those that reach the greatest heights are most noticeable because females are attuned to look upwards for predators. which model of sexual selection is least likely to impact this mating system?

Direct benefits

Explanation:

The direct benefits model of sexual selection refers to the selection by females based on the personal needs and requirements of the female. These personal requirements often refer to the sexual needs and nuptial gifts like a material that improves the health of the female etc. Here, the provided description refers to the physical aspects of the male and the territory the male possess. Therefore, the personal needs of the female are not considered in the described sexual selection for mating between fiddler crabs hence, direct benefits model is least likely to impact this mating system.

i disagree that there is little difference between adult female development and adult male development. sociological studies comparing female and male pathways to adulthood, revelead that there are sustancial differences between them. particularly, female and male differ from timing of marriage, when they began to live with children and the likelihood of combining wife/husband and parent roles.
