Abstract

Stable individual variation in ventral spotting patterns in Phyllomedusa trinitatis (Anura: Phyllomedusidae) and other Phyllomedusa species: a minimally invasive method for recognizing individuals. We describe a distinctive pattern of individually variable white ‘islands’ and dots on the ventral surfaces of the throat and forearm regions of male and female Phyllomedusa trinitatis. Crucially, we report from captive-reared individuals that these patterns are ontogenetically stable. We have used these patterns to recognize individual frogs in populations of 60 and more. Examination of the ventral surfaces of other Phyllomedusa species in museum specimens and from published accounts suggests that use of these patterns provides a generally useful, minimally invasive recognition method in this genus. We fnd that species previously classed as Phyllomedusa but now regarded as belonging to different genera lack these patterns.

Abstract

Variacao individual estavel no padrao de manchas ventrais em Phyllomedusa trinitatis (Anura: Phyllomedusidae) e em outras especies de Phyllomedusa: um metodo minimamente invasivo para o reconhecimento de individuos. Descrevemos aqui um padrao distintivo de “ilhas” e pontos brancos individualmente variaveis nas superficies ventrais das regioes da garganta e do antebraco de machos e femeas de Phyllomedusa trinitatis. Crucialmente, a partir de individuos criados em cativeiro relatamos que esses padroes sao ontogeneticamente estaveis. Usamos esses padroes para reconhecer pererecas individuais em populacoes de 60 ou mais individuos. O exame das superficies ventrais de outras especies de Phyllomedusa em especimes de museus e de relatos publicados sugere que o uso desses padroes fornece um metodo de reconhecimento minimamente invasivo e geralmente util nesse genero. Descobrimos que especies anteriormente classifcadas como Phyllomedusa, mas agora consideradas pertencentes a diferentes generos, nao possuem esses padroes.
