Mating System Variation in Woodhouse's Toad (Bufo woodhousii)

摘要: Sexual selection and mating-system variation was studied in two disjunct populations of Woodhouse's toad (Bufo woodhousii) with dissimilar breeding-period durations. In spite the differences duration, nightly operational sex ratios were roughly equivalent strongly male biased both populations, ranging from 0 to 0.5 population a prolonged breeding period, 0.2 explosively form. Although similar, some males mated up three females an extended whereas none polygynously short season. Two alternative reproductive tactics, satellite active-searching behavior, only exhibited by under high densities period. mating success positively related call rate, but independent size or number nights participation chorus activity. equally low, random size, activity, rate for population.
