AbstractDescribing osteological development is of great importance for understanding vertebrate phenotypic variations, form‐functional transitions and ecological adaptations. Anurans exhibit dramatic changes in their morphology, habitat preferences, diet and behaviour between the tadpole and frog stages. However, the anatomical details of their cranial

Abstract A comparative cytogenetic analysis showed that B. antartandica, B. leptopus, B. nibaldoi and B. taeniata share the same diploid number 2n = 26, but not the same fundamental number (FN), which was 52 in B. leptopus and 50 in the other three species. The karyotype of B. nibaldoi, including C‐band patterns and locations of the NORs, are described

AbstractA fossil gastric pellet from the Danian ‘Banco Negro Inferior’ of the Salamanca Formation at Punta Peligro Locality (Chubut, Argentina) and its 3D preserved fossil content is studied herein. The structure of the pellet and the condition of the enclosed bones suggest that it was produced by a bird of prey, although birds of any kind are as yet ...

New Species of Odontophrynus Reinhardt and Lütken 1862 (Anura: Neobatrachia) from Brazil and Uruguay
Journal of Herpetology, 2008Abstract A new species of the Neotropical frog genus Odontophrynus from coastal regions of Brazil and Uruguay is described. It is included in the americanus species group and has a diploid complement of 22 chromosomes. Odontophrynus sp. nov. is distinguished from the other species of the americanus group by having smaller size, head nearly as wide as ...

The tadpole of the endemic Chilean frog Eupsophus nahuelbutensis is described. The description includes external morphology, chondrocranium, and comments on natural history and systematics. This tadpole is endotrophic-nidicolous and unpigmented, resembling other larvae of the genus.

We describe a new species of Eupsophus from the Coastal Range of Southern Chile. The new taxon can be differentiated using an integrative taxonomic approach that includes advertisement call, reproductive mode, tadpoles, and mtDNA D-loop sequences. Based on karyological characters, the new species is assigned to the roseus Group (2N=30), and differs ...

Brachycephalus garbeanus is an aposematic toadlet, endemic to the Atlantic Forest in the mountains of the state of Rio de Janeiro, southeastern Brazil. Information regarding the ecology of species in this genus is scarce, with no information on most species, including B. garbeanus. We provide ecological information about B.
