Dynamics of chromosomal evolution in the genus Hypsiboas (Anura: Hylidae)
Genetics and Molecular Research, 2014 Hylidae is one of the most species-rich families of anurans, and 40% of representatives in this group occur in Brazil. In spite of such remarkable diversity, little is known about this family and its taxonomical and systematic features. Most hylids have 2n = 24, even though most of the cytogenetic data are mainly obtained based on the conventional ...

Thermal Tolerance in Anuran Embryos with Different Reproductive Modes: Relationship to Altitude
The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013 Anurans are ectothermic animals very sensitive to temperature, mainly during the embryonic stage. In addition, environmental temperature decreases with altitude, and the amphibian fauna changes. Therefore, we studied the relationship between the embryonic thermal tolerances of twelve species of anurans and the temperatures of their microhabitat along ...

Coloration of Anuran Tadpoles (Amphibia): Development, Dynamics, Function, and Hypotheses
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Colorations of anuran tadpoles surely function in many of the same ways that have been ascribed to color and pattern in other animals, but the paucity of data forces one to look to other groups to generate hypotheses. Such an action often occurs because of the difficulty of defining specific fitness parameters to larval forms.

The tadpole of Hypsiboas atlanticus (Anura, Hylidae) from northeastern Brazil [PDF]
Iheringia. Série Zoologia, 2009 The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1).

Colors and Some Morphological Traits as Defensive Mechanisms in Anurans
International Journal of Zoology, Volume 2009, Issue 1, 2009., 2009 Anurans may be brightly colored or completely cryptic. Generally, in the former situation, we are dealing with aposematism, and the latter is an example of camouflage. However, these are only simple views of what such colorations really mean and which defensive strategy is implied.
