Girinos de espécies de Hyla do grupo "Albosignata" (Amphibia, Anura, Hylidae)
Tadpoles of the five Hyla species belonging to the "albosignata" group were studied and illustrated, and their shared characters used to define the group. Tadpoles of the "albosignata" group were shown to be associated with mountain streams from 800m to higher elevation. Two groups of tadpoles have …

New research methods for the analysis of fossil Anura ilia and their utility for reconstructing the palaeoenvironment of Swartkrans Cave
Anura fossils are relatively common amongst microfauna assemblages but remain largely unanalysed because of a lack of expertise. This is unfortunate since Anura are effective indicators of environmental conditions as their life cycles and breeding patterns are integrally linked with temperature and …

Revisão taxonômica de espécies de Scinax duartei (B. Lutz, 1951) (Anura, Hylidae)
A taxonomic population study of the Scinax duartei species complex was undertaken using morphological and morphometrical characters analyses from adults, tadpoles, as well as vocalization parameters. I recognize the complex to be formed by four species: S. duartei (B. Lutz, 1951 ), S. caldarum (B. …

Anura of Eastern South Dakota: Their Distribution and Characteristics of Their Wetland Habitats, 1997-1998
… associated with wetlands used by breeding Anura and to determine anuran distribution within eastern South Dakota. The chorus frog (Pseudacris triseriata triseriata and P. t. maculata), northern leopard frog (Rana pipiens) and great plains toad (Bufo cognatus) were cosmopolitan in …

Osteology of Calluella guttulata (Blyth 1855) and Associated Commentary on Evolution in the Family Microhylidae (Anura)
Microhylid osteology is a morass of unusual structures and repetitive convergent evolution. The available phylogenetic information is limited, and the osteological information barely scratches the surface of the diversity present in the group, but even this much is enough to begin to identify …

Estudo da atividade reprodutiva de hyla truncata Izecksohn, 1959 (Anura, Hylidae) na Restinga de Maricá, RJ
… between ovary and fat body weight , like many anurans from temperate zone. The results suggest that fat body changes were not influenced directly by reproduction, and probably varied due to nutrition. Spermatogenesis and ovogenesis were continuous, and the treefrogs were physiologically capable …

Interrelationships of conspecific responses to call quality and body size of male Rana clamitans (Anura: Ranidae)
The vocal behavior of male Rana clamitans was studied during the summers of 1974-1976 near Blacksburg, Montgomery Co., Virginia to test the hypothesis that call quality varies among callers and this variation produces different responses in recipient conspecifics. The studied call repertoire …

Taxonomia das espécies de Hyla pertencentes ao grupo de H. Rubicundula Reinhardt & Lutken, 1862 (Amphibia, Anura, Hylidae)
The Hyla rubicundula group is currently composed by three species: H. rubicundula Reinhardt & Lütken. 1862; H. tritaeniata Bokermann. 1965; H. anataliasiasi Bokermann, 1972. We can add to these H. elongata Lutz, 1925, considered junior synonym of H. rubicundula. The absence of strong diagnostic …

Taxonomia, variação morfológica e distribuição geográfica das espécies do grupo Hyla circumdata (Cope, 1870) (Amphibia, Anura, Hylidae)
The Hyla circumdata species group currently comprises eleven species, which are distributed over mountain stream habitats in Atlantic Tropical Forest, with altimetric range over 500 m. This group is diagnosed by transverse bands on the posterior surface of thighs and hypertrophied prepollex. …
