The reproductive dynamics of temperate amphibians: a review.

Abstract

The annual life cycle of pond breeding amphibians is characterized by periodical migrations between three critical habitats: breeding, post breeding - feeding - and hibernating. The breeding season starts with the migration of the reproductive adults toward the breeding site and is characterized by intense manifestations in behavior and development of secondary sexual characters. Time spent in the water is strongly influenced by the outcome of success in courtship, insemination and/or fertilization. The aim of this review is to summarize some major findings of the main research directions regarding the reproductive dynamics of temperate (and especially European) amphibians. These are presented in detail for the most studied European species: Triturus vulgaris, Bufo bufo, B. calamita and Rana temporaria.
