The Biology of Plethodontid Salamanders

The chapter describes sperm competition as a major factor in the sexual behavior of many species. This is clearly a major factor that has led to the evolution in males of a variety of behavior patterns, morphological features and physiological processes that serve to reduce its impact, such as mate-guarding and sexual dimorphism. The potential for sperm competition may have shaped the evolution of anuran sexual behavior. In particular, amplexus, by which males sequester and guard females has evolved as an adaptation that prevents sperm competition. Among urodeles, the necessary conditions for sperm competition, internal fertilization, multiple mating by females and sperm storage are widespread, and several recent studies provide evidence that it has been very important in the evolution of urodele sexual behavior. A female strategy that incorporates multiple mating and sperm competition imposes a strong selection on how much males invest in sperm production and in the way that males allocate sperm to individual matings. This also leads to a diverse array of behavioral patterns and other adaptations.
