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

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...

Natural History Museum The University of Kansas 24 Septem ber 1997 Number

Andean hylid frogs of the genus Hyla are reviewed. Eight groups of Hyla recognized in the Andes are defined; the species in two of these groups are treated in detail. The large H. armata, characterized by hypertrophied forelimbs and clumps of nuptial spines on the prepoUex and humerus in males, and a stream-adapted tadpole with a LTRF up to 15/17, is the sole recognized species in the H. armata...

Evaluating the karyotypic diversity in species of Hyla (Anura; Hylidae) with 2n = 30 chromosomes based on the analysis of ten species.

Ten species of Hyla with 2n = 30 from Brazilian fauna were analysed cytogenetically. Hyla minuta is the unique presenting all bi-armed metacentric or submetacentric chromosomes in the karyotype, therefore, with the highest FN = 60. The remaining species have a variable number of uni-armed telocentric or subtelocentric chromosomes: H. cruzi, H. elianeae, and H. rubicundula with three pairs (FN =...

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...
