Studies in the reproductive Physiology of the Amphibia
The changes occurring in the red blood cells in infective illness are amongst the least carefully studied problems of haematology. In spite of the fact that these anamias are extremely common, it is difficult to find adequate literature to make possible even a clear description of the blood picture …

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 …

The chromatic function in Xenopus Laevis
In few Amphibia is the extent of visible pigmentary effector activity as striking as in the case of the South African clawed toad. Nevertheless, there is no account on record of the phenomena of colour response in this species.

Dieta de Eleutherodactylus binotatus (Spix, 1824) Amphibia, Leptodactylidae) em um fragmento de mata de Belmiro Braga, Zona da Mata, MG, Brasil
Diet studies in anurans have used pre-established concepts, based on anecdotal cases, generally developed in assemblages with similar features. Nevertheless, few authors tested such concepts and classifications. lt is well known that anuran size is correlated to the size of the ingested preys. Many …
