Abstract: Snout-vent lengths of large samples of natterjacks were measured at four relatively isolated sand-dune breeding sites in two successive years. It was hoped t hat the size distributions would indicate whether satisfactory recruitment into t he breeding cohort was taking place. Significant differences were found between males and females. between the four sites and between years. It is inferred that one group consists mainly of young individuals. reflecting high toad let product ion. while the other three groups have a large proportion of older adults as a consequence of poorer breeding success. The possible reasons for these differences are discussed.
