The tadpoles of Hyla rufitela (Anura: Hylidae).

Prevalence of cadmium resistance in Staphylococcus sciuri isolated from the Gray Treefrog, Hyla chrysoscelis (Anura: Hylidae)

Conserved karyotypes in the Hyla pulchella species group (Anura, Hylidae).

Cytogenetic analyses were done on specimens of Hyla marginata and on three populations of H. semiguttata differing in morphology and in the physical parameters of their advertisement call, as well as in individuals of Hyla sp. (aff. semiguttata). All specimens had 2n=24 chromosomes with a morphology very similar to that of other 24-chromosome Hyla species. Hyla semiguttata and H. marginata show...

A molecular perspective on the phylogeny of the Hyla pulchella species group (Anura, Hylidae).

A molecular phylogenetic analysis of the Hyla pulchella species group was performed to test its monophyly, explore the interrelationships of its species, and evaluate the validity of the taxa that were considered subspecies of H. pulchella. Approximately 2.8 kb from the mitochondrial genes 12s, tRNA valine, 16s, and Cytochrome b were sequenced. The analysis included 50 terminals representing 10...

Bioacoustic analysis of advertisement call in Hyla nana and Hyla sanborni (Anura, Hylidae) in Botucatu, São Paulo, Brazil.

Vocal communication traits of Hyla nana and Hyla sanborni, of the nana species group, were studied from August 1997 until June 1999 in two large permanent ponds located in an open field in Botucatu, São Paulo State. One hundred thirty-one individuals, 71 of H. nana and 58 of H. sanborni, were recorded in the beginning of their vocalization activity and during chorus vocalization. The rhythms of...

The tadpole of Sphaenorhynchus caramaschii, with comments on larval morphology of Sphaenorhynchus (Anura: Hylidae).

We describe the tadpole of Sphaenorhynchus caramaschii. It differs from tadpoles of other species of Sphaenorhynchus in having a short spiracle, submarginal papillae, and alternating short and large marginal papillae in the oral disc. Some larval characteristics, like morphology and position of the nostrils, length of the spiracle, and size of the marginal papillae on the oral disc are discusse...
