Genetic and morphometric variability in Caiman latirostris (broad‐snouted caiman), Reptilia, Alligatoridae [PDF]

Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2009
AbstractCaiman latirostris (broad‐snouted caiman) is a crocodilian species from Argentina subject of management plans. The goal of this study was estimating the distribution of genetic variability using RAPD markers and quantitative traits in wild populations of C. latirostris from Santa Fe province, Argentina.

Ultraviolet radiation-induced genotoxic effects in the broad-snouted caiman, Caiman latirostris

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2010
Ultraviolet 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 ...

Growth Curves of Wild and Reintroduced Broad-Snouted Caimans (Caiman latirostris) and Their Management Implications [PDF]

South American Journal of Herpetology, 2020
We describe body growth functions of broad-snouted caimans (Caiman latirostris) for wild and reintroduced individuals. Snout–vent length (SVL, cm) and age of young individuals and adult females were recorded for two different groups: (Py) animals born in the Proyecto Yacare ranching program, from eggs collected in the wild; and (Wy) wild caimans Class ...

Light microscopic and immunohistochemical study of the trachea of the broad-snouted caiman (Caiman latirostris) [PDF]

Veterinární Medicína, 2011
The purpose of this study was to examine the tracheal structure of the crocodile Caiman latirostris using light microscopy, histochemical and immunocytochemical techniques. The tracheal epithelium of C. latirostris consists of a ciliated pseudostratified

ISOLATION OF SALMONELLA SPP. FROM YACARE CAIMAN (CAIMAN YACARE) AND BROAD-SNOUTED CAIMAN (CAIMAN LATIROSTRIS) FROM THE ARGENTINE CHACO

Journal of Wildlife Diseases, 2011
Presence of Salmonella spp. was evaluated in yacare caiman (Caiman yacare) and broad-snouted caiman (Caiman latirostris) from a ranching facility in the Argentine Chaco. Crocodilian ranching programs are based on captive breeding of wild-harvested eggs and release of excess hatchlings into the wild.

Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA [PDF]

Genetics and Molecular Biology, 2009
In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo,

Histological and immunohistochemical study of the thyroid gland of the broad-snouted caiman (Caiman latirostris) - doi: 10.4025/actascibiolsci.v35i4.18444

Acta Scientiarum: Biological Sciences, 2013
The broad-snouted caiman, Caiman latirostris, is widely distributed in countries of South America. In Brazil it is considered an endangered species because of natural habitat destruction and illegal hunting.
