• Abstract

  Although only a few anurans had their chromosomes investigated up to now, the data yet obtained are exciting because it helps to clarify the mechanisms of karyotypic evolution. Classical, and more recently molecular markers have been used to investigate the chromosomal variation in anurans, improving the comparative cytogenetics. In the present work, the karyotypes of Phyllomedusa (sub-pr…

  Classical and molecular markers for chromosomal studies in anurans, AP.R

• Abstract

  Recently, the systematics of anurans has been modified based on DNA sequencing, external morphology and karyotype studies. In some anurans groups, intra- and intergeneric relationships remain uncertain. The goal of this project is provide new characters that can, in association with molecular and cytogenetic data, help to understand the intra- and intergeneric relationships of Pseudopalud…

  Comparative study of sperm ultrastructure of frog species of the subfamily Leiuperinae (Amphibia, Anura, Leptodactylidae), AP.R

• Abstract

  AbstractThe taxonomic and phylogenetic relationships of the genus Phyllomedusa have been amply discussed. The marked morphological similarities among some species hamper the reliable identification of specimens and may often lead to their incorrect taxonomic classification on the sole basis of morphological traits. Phenotypic variation was observed among populations assigned to either P. …

• Abstract

  The spermatozoa of the genus Codakia, Lucinidae family, will be described using the Transmission Electron Microscopy (TEM). There is controversy about the phylogenetic relationships in the superfamily Lucinoidea, which once included six families (Lucinidae, Fimbriidae, Thyasiridae, Ungulinidae, Mactromyidae and Cyrenoididae), however, by molecular analysis, currently comprises only two, L…

  Ultrastructure spermatozoa analysis of species of the genus Codakia (Lucinidae, Bivalvia) from North Coast of São Paulo state, BP.IC

• Abstract

  Comparative cytogenetic studies provide scenarios of the chromosomal evolution of related taxa and represent an important approach to the identification of chromosomal homologies among species, which is also useful for taxonomic approach. The taxonomic and phylogenetic relationships of the frogs of the genus Phyllomedusa have been amply discussed. The Phyllomedusa genus is an interesting …
