Long-term effects of in ovo exposure to an environmentally relevant dose of atrazine on the thyroid gland of Caiman latirostris.

Environmental Research, 2020
The increased incidence of human thyroid disorders, particularly in women, suggests that the exposure to endocrine-disrupting compounds (EDCs) together with sex-related factors could play a role in thyroid dysregulation. Since the herbicide atrazine (ATZ)

Genital anatomy and copulatory interactions in the broad snouted Caiman (Caiman latirostris)

The Anatomical Record, 2021
The broad snouted caiman is a crocodylian native to South America that is subject to extensive conservation management in both wild and farming environments.

On the dependence on metabolism of the cochlear potentials in Caiman (Caiman crocodilus)

Zeitschrift f�r Vergleichende Physiologie, 1971
Investigation of the cochlear potentials in a reptile shows that the microphonics contain 2 components as previously observed in birds. The potentials depend to varying degrees and in a similar way as in birds on metabolism; the time course is expanded by a factor of 20.

CEPHALOSPORIOSIS IN THREE CAIMANS

Journal of Wildlife Diseases, 1972
A fatal diffuse granulomatous pneumonia and focal necrotizing hepatitis were found at necropsy of three 6-month old caimans. Centers of the widely disseminated, discrete lesions in the lungs had a branching fungus with septate hyphae, chlamydospores, and elliptical and cigar-shaped conidia.

Caiman latirostris meat characterization: Evaluation of the nutritional, physical and chemical properties of meat from sustainable ranching program in Argentina

, 2020
The scientific community has made considerable efforts to improve the production of protein from traditional sources. Currently it has also been focused on non-conventional protein sources, such as those produced in conservation and sustainable use ...

The Hearing of the Caiman, Caiman crocodilus

1990
The caiman is an alligator which, together with the crocodiles and gavials, form the few remaining reptilian descendents of the huge group of ruling diapsid reptiles of the Mesozoic period, the archosaurs (Fig. 1.2). They are closely related to the birds, a relationship which is immediately apparent in a comparison of the structure of the inner ear ...

Growth rates of black caiman Melanosuchus niger and spectacled caiman Caiman crocodilus, and the recruitment of breeders in hunted caiman populations

Biological Conservation, 1991
Abstract Hunted populations of black caiman Melanosuchus niger are unable to persist, but many hunted populations of spectacled caiman Caiman crocodilus appear to be maintaining their numbers. Previous authors explained these observations by noting that black and spectacled caiman differ in the length of time that individuals are highly ...

Cochlear potentials and auditory evoked potentials in the caiman (Caiman crocodilus (L.))

Electroencephalography and Clinical Neurophysiology, 1990
Brain-stem auditory evoked potentials (BAEPs) and round window compound action potentials (CAPs) in response to rarefaction and condensation clicks were recorded from anaesthetized and artificially respired caiman. The recorded wave forms were substantially different from the brain-stem and round window potentials recorded in mammals, including man. In

Effects of stress and ACTH on plasma corticosterone levels in the caiman Caiman crocodilus

General and Comparative Endocrinology, 1976
Abstract Corticosterone levels in blood plasma of the caiman were measured in response to the collection of blood and to the administration of mammalian ACTH. Blood collection resulted in an increase in plasma corticosterone levels; the highest levels of corticosterone were observed 2 hr after the initial sample, and corticosterone levels declined ...

Detection of Leptospira spp. in Captive Broad-Snouted Caiman (Caiman latirostris)

EcoHealth, 2019
Leptospira sp. is an important waterborne zoonotic bacterium, known to cause infection in animals and humans worldwide. The role of reptiles in the transmission of this microorganism is poorly understood and historically neglected. This study aimed to investigate the presence of anti-Leptospira spp.
