Hasumi, M.: Reproductive behavior of the salamander Hynobius nigrescens: monopoly of egg sacs during scramble competition. Journal of Herpetology (USA, International) 28(2): 264-267, June 1994. doi: 10.2307/1564635

Abstract: The major findings in this study were as follows: (1) momentarily forming a spawning pair just before scramble competition, (2) no correlation between male size and monopolization potential of egg sacs during scramble competition, and (3) a negative correlation between the monopolist male's SVL and head width and the length of time the mating balls with scrambler males last (mating ball duration).
