Coy Males and Seductive Females in Cyrtophora citricola Spider

This scientific study explores the behavior of sexually cannibalistic colonial spiders, specifically focusing on the mating dynamics between males and females. The research examines the preferences of male spiders and investigates the factors that contribute to male choosiness. The study also examines the effects of sexual cannibalism on both male and female reproductive success.

  4. Discussion Questions • Describe the three categories of females listed in the figure. • Which category do males prefer? • Provide evidence from the figure. • Why does this figure use a stacked bar graph instead of a double bar graph that shows the light and dark bars side-by-side?

  5. Discussion Questions • What features would make females of a particular reproductive status more or less appealing to males? • Do you think younger or older males would be choosier about their mates? Use the concept of reproductive success to explain your answer.

  6. Discussion Questions • How do you think sexual cannibalism affects female and male reproductive success? • Scientists hypothesize that both sexual cannibalism and colonial living contributed to the evolution of male choosiness in C. citricola. Describe how both factors might contribute to the evolution of this behavioral strategy.

  7. Discussion Questions • Can you think of other factors that could cause male choosiness to evolve? Use the concept of reproductive success to support your answers.
