Nondestructive Evaluation of Metal Bioaccumulation and Biochemical Biomarkers in Blood of Broad‐Snouted Caiman (Caiman latirostris) from Northeastern Brasil

Environmental Toxicology and Chemistry
Studies on the bioaccumulation and toxicity of contaminants in Crocodylians are scarce. We evaluated alterations in concentrations of the nondestructive biomarkers butyrylcholinesterase (BChE), glutathione‐S‐transferase (GST), superoxide dismutase (SOD),

Artisanal fishing affects the local distribution of broad‐snouted caiman (Caiman latirostris) within the Atlantic Forest of Brazil

Aquatic conservation
Artisanal fishing is an important subsistence practice in freshwater habitats worldwide, but overexploitation threatens the conservation of several nontarget species including crocodylians.

Prevalence of injuries in a Caiman crocodilus chiapasius (Bocourt 1876) population from the South Pacific coast of Mexico

Studies on Neotropical Fauna and Environment
Crocodilians injuries are indicators of their health and social interactions. We analyzed the prevalence and distribution of injuries in spectacled caiman (Caiman crocodilus chiapasius) from the Biosphere Reserve of La Encrucijada (BRLE) in relation to ...

Unexpected but unsurprising lineage diversity within the most widespread Neotropical crocodilian genus Caiman (Crocodylia, Alligatoridae)

, 2020
Species discovery methods utilizing coalescent-based approaches are powerful tools for detecting cryptic lineages within morphological conservative groups, thus being an important methodology of integrative taxonomic research.

From the river to the ocean: mitochondrial DNA analyses provide evidence of spectacled caimans (Caiman crocodilus Linnaeus 1758) mainland–insular dispersal

Biological Journal of the Linnean Society, 2021
There are few studies that have investigated the evolutionary history of large vertebrates on islands off the Caribbean coast of South America. Here we use the spectacled caiman (Caiman crocodilus) to investigate among- and within-population patterns ...

Studies on chromoproteins of cardiac and skeletal muscle of caimans (Caiman sclerops)

Pfl�gers Archiv European Journal of Physiology, 1975
In a number of caimans (Caiman sclerops) we were unable to find traces of myoglobin in any of the histologically clearly cross-striated cardiac and skeletal muscles using spectrometric methods. The red colour of the heart is due to a high concentration of cytochrome c.

Antioxidant effect of acerola fruit powder, rosemary and licorice extract in caiman meat nuggets containing mechanically separated caiman meat.

Meat Science, 2020
The aim of this work was to evaluate the antioxidant effect of acerola fruit powder, rosemary and licorice extract in caiman meat nuggets containing high amounts of mechanically separated caiman meat (MSCM) during 120 days of frozen storage.

Biomarkers of geno- and cytotoxicity in the native broad-snouted caiman (Caiman latirostris): Chromosomal aberrations and mitotic index.

Mutation research, 2021
We evaluated the sensitivity of the chromosomal aberration (CA) and mitotic index (MI) assays on peripheral blood lymphocytes (PBLs) of Caiman latirostris, following ex vivo exposure to the alkylating agent, MMS.
