Abstract

I studied the reproductive behaviour of a population of prolonged-breeding Bufo woodhousei in central Arizona. Choruses formed in discrete and consistent areas of ponds, and males actively defended calling sites within these aggregations. Call rate and calling site residency, but not size, were important factors determining the outcome of male-male disputes within choruses. Females visited choruses to select males, and oviposition occurred away from the calling site of selected males. Natural and experimental observations revealed that females prefer males with a high call rate. Preliminary results indicated that large males did not achieve greater reproductive success, nor was there any suggestion of assortative mating in size of mated pairs. It is concluded that B. woodhousei has a lek mating system, possible because of its prolonged breeding period. These results are discussed in relation to other anuran mating systems and sexual selection in general.
