Physiological and morphological responses to feeding in broad-nosed caiman (Caiman latirostris) [PDF]

Journal of Experimental Biology, 2007
SUMMARY Broad nosed caiman are ectotherm sauropsids that naturally experience long fasting intervals. We have studied the postprandial responses by measuring oxygen consumption using respirometry, the size changes of the duodenum, the distal small intestine, and the liver, using repeated non-invasive ultrasonography, and by investigating

Comparison of plasma dipeptidyl peptidase IV activity in two caiman species: Caiman latirostris and Caiman yacare (Crocodylia, Alligatoridae) [PDF]

, 2011
Dipeptidyl peptidase IV (DPPIV) is a well-characterized protease with broad substrate specificity, functionally-related to the activity of many bioactive peptides.

Biomarkers of genotoxicity, immunotoxicity and oxidative stress on Caiman latirostris (Broad-snouted caiman) hatchlings exposed to pesticide formulations and mixtures widely used in agriculture

Environmental Advances, 2021
Pesticide formulations are currently considered as one of the main factors responsible for environmental contamination worldwide. Consequently, several wild species can be affected by the over use of pesticides related to agriculture activity. The aim of

Immunotoxicity of commercial-mixed glyphosate in broad snouted caiman (Caiman latirostris)

Chemico-Biological Interactions, 2016
The expansion and intensification of agriculture during the past 50 years is unprecedented, and thus environmental problems have been triggered at different scales. These transformations have caused the loss of habitat and biodiversity, and disruption of the structure and functioning of ecosystems.

Intraspecific isotopic niche variation in broad-snouted caiman (Caiman latirostris)

Isotopes in Environmental and Health Studies, 2013
Strategies to minimise intraspecific competition are common in wild animals. For example, individuals may exploit food resources at different levels of the food chain. Analyses of stable isotopes are particularly useful for confirming variations in an intraspecific niche because the chemical composition of animals tends to reflect both the food ...

The relationship between nesting habitat and hatching success in Caiman latirostris (Crocodylia, Alligatoridae) [PDF]

Phyllomedusa: Journal of Herpetology, 2006
The Broad-snouted Caiman uses different habitats for nesting; it has temperature-dependent sex determination (TSD) and nesting habitat selection by females could affect sex and other hatchlings characteristics.

Caiman yacare (Yacare Caiman): Triplets [PDF]

, 2021
The Broadsnouted Caiman (Caiman latirostris) and Yacare Caiman (Caiman yacare) are the two crocodilian species that inhabit Argentina (Prado et al. 2012. Cuad. Herpetol. 26. Suppl 1:403– 410).

Presence of red fire ants (Solenopsis invicta Buren) in broad-snouted Caiman (Caiman latirostris) nests [PDF]

, 2012
The presence of Solenopsis invicta in Caiman latirostris nests is suspected to be a possible cause of death in caiman hatchlings, but this has not been documented within the native distribution of this ant. In crocodilian ranching programs, wild eggs are

Morphological comparison of the larynx and trachea of Chelonia mydas (Linnaeus, 1758), Caiman yacare (Daudin, 1802) and Caiman latirostris (Daudin, 1802) [PDF]

Anais da Academia Brasileira de Ciências
The larynx is in the lower respiratory tract and has the function of protecting the airways, controlling, and modulating breathing, assisting the circulatory system, and vocalizing. This study aims to describe the anatomy and histology of the skeleton of

Nest-sharing behavior of captive Broad-snouted caimans (Caiman latirostris): cooperation or exploitation?

Amphibia-Reptilia, 2022
Abstract Communal egg-laying is not frequently observed in crocodilians that exhibit nest attendance. However, it has been reported for both wild and captive Caiman latirostris. To understand the proximate causes of communal nesting, we aim to describe the nesting behavior of caimans during communal egg-laying in a captive population.
