About this book

Language: Bilingual in English and Italian

Tadpoles of Italy is contributes to the recognition and biology of larval stages of Italian Anurans. The book's framework is built on two fundamental resources: an innovative iconography combining scientific accuracy and aesthetically pleasing images on the one hand, and a synthetic text offering an updated overview of the ecology and behaviour of Anuran larvae, on the other. This monograph is a useful tool for live tadpole identification through observation of external morphology, colouration and behaviour. To this end, it includes a dichotomous key to be used in the field, which does not take into account some features used in amphibian larvae identification, as such as horned teeth. Tadpoles have been mainly represented in Gosner developmental stages 35-39, which are widely considered the most significant for species identification. In order to avoid mistakes in depicting and describing the larvae, for a few genera (for instance Rana and Pelophylax), species determination was verified after metamorphosis and/or genetical analysis. A special effort has been made to showing variations in shape and colouration regarding Anuran species whose larvae are known to display a high degree of polymorphism due to variations of environmental parameters.

Summary in Italian:
Girini d’Italia vuole essere una proposta di approfondimento sul riconoscimento e sulla biologia delle forme larvali degli Anuri italiani. E’ articolato su due punti fondamentali: una iconografia innovativa nella rappresentazione dei girini che coniuga, all’imprescindibile rigore naturalistico, la bellezza del segno e della sfumatura e un testo, quasi didascalico, in grado di fornire un quadro aggiornato sui principali aspetti della vita delle larve degli Anuri italiani. Il volume, inoltre, vuole essere un efficace strumento per la determinazione dei girini sulla base della loro attenta osservazione dal vivo delle forme e delle cromie. A tale riguardo è stata elaborata una nuova chiave dicotomica che - pur non considerando caratteristiche consuete nella determinazione specifica delle forme larvali degli Anuri (es. cheratodonti) - sia in grado comunque di condurre alla corretta individuazione delle diverse specie (o generi).  Le forme larvali sono state rappresentate principalmente negli stadi Gosner 35-39, ritenuti i più significativi al fine della determinazione specifica delle larve. Per non incorrere in errate raffigurazioni e attribuzioni, per alcuni generi (es. Rana e Pelophylax) la determinazione specifica è avvenuta al termine della metamorfosi o sulla base di analisi genetiche delle forme larvali. Inoltre, laddove ritenuto significativo, sono state rappresentate variazioni nella forma e nei colori dei girini, all’interno della stessa specie, al fine di sottolineare l’importante grado di plasticità che possono mostrare le forme larvali degli Anuri  al variare di alcuni parametri ambientali.
