Genital anatomy and copulatory interactions in the broad snouted Caiman (
AbstractThe broad snouted caiman is a crocodylian native to South America that is subject to extensive conservation management in both wild and farming environments. Although reproductive behaviors like egg laying and clutch care have been examined in this species, little else is known about their copulatory system.

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),

Detectability of Caiman latirostris (Crocodylia: Alligatoridae) in Night Count Surveys
South American Journal of Herpetology, 2022. Night count surveys are one of the most used methods to study distribution and population parameters in crocodilians. However, there are some methodological constraints that prevent the visualization of animals submerged or hidden behind vegetation. We

Ultraviolet radiation-induced genotoxic effects in the broad-snouted caiman, Caiman latirostris
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2010Ultraviolet radiation (UVR) has many positive effects, but overexposure of organisms can generate alterations in DNA, either directly or indirectly, inducing mutagenic and cytotoxic lesions. The aim of this study was to evaluate the genotoxic effects of UVA-B/visible light in the broad-snouted caiman (Caiman latirostris), using the micronucleus (MN ...

First record of twin hatchlings in Caiman latirostris (Daudin, 1802) in the Atlantic Forest, Brazil
Journal of Environmental Analysis and ProgressEmbryo twinning is quite common in reptiles, possibly due to atypical incubation conditions, although few specimens hatch and reach adulthood, especially in the wild.

Zoo Biology
The shell of crocodilian eggs is highly fragile, especially during the early stages of development, making them susceptible to cracking during laying or collection, often resulting in embryo mortality.

Environmental Science and Pollution Research
The molecular pathways involved in oviductal adenogenesis are highly conserved among vertebrates. In this work, we study the histomorphological changes and molecular pathways involved in Caiman latirostris oviductal adenogenesis and the effects of in ovo exposure to environmentally relevant doses of endosulfan (END) and atrazine (ATZ) on these ...

The sex ratio of a population dictates intraspecific interactions, including agonistic behaviours and mating. Moreover, discrepancies in the male-to-female proportion may reduce reproductive processes and threaten population maintenance.
