O status taxonômico de Hyla cochranae Mertens e recaracterização de Aplastodiscus A. Lutz (Anura, Hylidae)

Abstract

ABSTRACT. The taxonomic status of the Hy/a cochranae Mertens and recharac· terization of Ap/astodisclIs A. Luiz (Anura, Hylidae). Hy/a cochranae Mertens, 1952 is revalidated and the description of the tadpole and vocalization is provided. Based on externai morphology, the genus Aplastodiscus A. Lutz, 1950 is recharacterized and a redescription of A. perviridis A. Lutz, 1950 is given. New data on geographical distribution and biology 0f both species are provided.

Vocalizações e interações acústicas em Hyla raniceps (Anura, Hylidae) durante a atividade reprodutiva

“…Neste trabalho, foi encontrada uma correlação significativa entre número de notas e temperatura do ar, duração de notas e peso do macho, duração de notas e temperatura do ar, taxa de repetição e CRC do macho vocalizante e entre a taxa de repetição e peso do macho vocalizante. De acordo com alguns autores (DUELLMAN & TRUEB, 1986;CRESPO et al, 1989;SULLIVAN & MALMOS, 1994;GARCIA et al, 2001), há forte influência da temperatura do ar na variação dos parâmetros acústicos em várias espécies de anuros, pois com o aumento da temperatura, aumenta a taxa de canto, com conseqüente aumento da taxa metabólica e gasto de energia (WELLS et al, 1996). Outros autores (GIACOMA et al, 1997;OVASKA & CALDBECK, 1997) …”

Diet of Aplastodiscus perviridis Lutz 1950 (Anura, Hylidae) in subtemperate forests of southern Brazil

“…Except for reproduction studies (Haddad and Prado, 2005;Zina et al, 2007), distribution notes (Both et al, 2006), taxonomy (Garcia et al, 2001) and cell biology (Carvalho et al, 2009), studies on the genus Aplastodiscus are scarce, and there are no records on feeding behavior. Considering the importance of natural history studies and the limited available knowledge about this genus, the aim of this study was to contribute to filling these gaps, describing and analysing the diet composition of A. perviridis during the breeding season in areas associated to Araucaria moist forests in Rio Grande do Sul, Brazil.…”

The first species of Aplastodiscus endemic to the Brazilian Cerrado (Anura, Hylidae)

“…The species are stream-breeding treefrogs, usually of green color and medium size. The Aplastodiscus perviridis species Group includes Aplastodiscus perviridis Lutz 1950 and Aplastodiscus cochranae (Mertens 1952), which share, among other characters, bicolored irises, no webbing between toes I and II, and reduced webbing among their remaining toes (Garcia et al 2001). …”
