1. Contenção farmacológica de jacaré-tinga Caiman crocodilus Linnaeus, 1758 com cetamina S (+) e cetamina racêmica, isolada ou em associação com o midazolam
CHAPTER 2: This work was developed with the purpose of evaluating and comparing two different dosages of ketamine and midazolam in Caiman crocodilus. We used twelve common caiman divided into two groups of six animals. Group 1 received midazolam 2 mg/kg IM and ketamine 20 mg/kg IM, as in group 2, we used the same dosage of midazolam with ketamine at 40 mg/kg

2. Cranial sexual discrimination in hatchling broad-snouted caiman (Caiman latirostris)
Broad-snouted caiman (Caiman latirostris) hatchlings present a consistent sexual dimorphism in their cranium shape and size. Male hatchlings have smaller crania than females. Using multivariate statistical analyses it is possible to discriminate sex in broad-snouted caiman hatchlings by their cranial shape with a reasonable efficiency. The understanding of s

3. Detection of Antibodies to a Pathogenic Mycoplasma in American Alligators (Alligator mississippiensis), Broad-Nosed Caimans (Caiman latirostris), and Siamese Crocodiles (Crocodylus siamensis)
An epidemic of pneumonia with fibrinous polyserositis and multifocal arthritis emerged in captive American alligators (Alligator mississippiensis) in Florida, United States, in 1995. Mycoplasma alligatoris sp. nov. was cultured from multiple organs, peripheral blood, synovial fluid, and cerebrospinal fluid of affected alligators. In a subsequent experimental

4. Molecular evidence for the origin of birds.
The major groups of amniote vertebrates appeared during a relatively short time span at the end of the Paleozoic Era, a fact that has caused difficulty in estimating their relationships. The fossil record suggests that crocodilians are the closest living relatives of birds. However, morphological characters and molecular sequence data from living amniotes ha

5. Incremental lines of von Ebner in dinosaurs and the assessment of tooth replacement rates using growth line counts
Dinosaur dentine exhibits growth lines that are tens of micrometers in width. These laminations are homologous to incremental lines of von Ebner found in extant mammal and crocodilian teeth (i.e., those of amniotes). The lines likely reflect daily dentine formation, and they were used to infer tooth development and replacement rates. In general, dinosau

6. The mitochondrial genomes of the iguana (Iguana iguana) and the caiman (Caiman crocodylus): implications for amniote phylogeny.
The complete mitochondrial genomes of two reptiles, the common iguana (Iguana iguana) and the caiman (Caiman crocodylus), were sequenced in order to investigate phylogenetic questions of tetrapod evolution. The addition of the two species allows analysis of reptilian relationships using data sets other than those including only fast-evolving species. The cro

7. Generic affinities among crocodilians as revealed by DNA fingerprinting with a Bkm-derived probe.
Genetic fingerprint profiles have been successfully used for establishing biological relationships, in linkage analysis, and in studies of population structure but have not so far been used for ascertaining phylogenetic relationships among related groups of species and genera. This is largely because these profiles are thought to evolve too rapidly to be inf

8. Beta-keratins of turtle shell are glycine-proline-tyrosine rich proteins similar to those of crocodilians and birds
This study presents, for the first time, sequences of five beta-keratin cDNAs from turtle epidermis obtained by means of 5′- and 3′-rapid amplification of cDNA ends (RACE) analyses. The deduced amino acid sequences correspond to distinct glycine-proline-serine-tyrosine rich proteins containing 122–174 amino acids. In situ hybridization shows that beta-
