Effective population size of broad-snouted caiman (Caiman latirostris) in Brazil: A historical and spatial perspective

open access: yesGlobal Ecology and Conservation, 2021
Caiman latirostris has a large geographic distribution, that includes Argentina, Bolivia, Brazil, Paraguay, and Uruguay. In Brazil illegal hunting and land use change have caused population decline, relatively well documented in the last three decades ...

Oculocardiac Reflex and Autonomic Modulation in a Broad-Snouted Caiman (Caiman latirostris)

open access: yesActa Scientiae Veterinariae
Background: The oculocardiac reflex (OCR) is a neurophysiological response mediated by the vagus nerve, triggering changes in heart rate and rhythm in response to pressure applied to the ocular globe.

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

open access: yesVeterinární 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

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

open access: yesSouth 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

Environmental challenges influencing maternal care and nesting success in the Broad-snouted Caiman

open access: yesGlobal Ecology and Conservation
Maternal care and nesting success are critical components of the reproductive cycle in crocodilians, and are strongly influenced by environmental conditions.

Effects of change in temperature on the cardiac contractility of broad-snouted caiman (Caiman latirostris) during digestion.

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, 2021
In many reptiles, digestion has been associated with the selection of higher body temperatures, the so-called post-prandial thermophilic response. This study aimed to investigate the excitation-contraction (E-C) coupling in postprandial broad-snouted ...

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

open access: yesPhyllomedusa: 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.

Systematization, Description and Territory of The Middle and Rostral Cerebral Arteries in Broad-Snouted Caimans (Caiman latirostris) [PDF]

open access: yesActa Scientiae Veterinariae, 2018
Background:  : : Information on the arterial vascularization of the broad-snouted caimans’ brain (Caiman latirostris), a specie from the Brazilian fauna, is inexistent and the literature consulted yielded only one description about the development of ...

Roars, Rumbles, and Resonance: A Systematic Review and Meta-Analysis of Crocodylian Acoustic Signals. [PDF]

open access: yesEcol Evol
Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care. Despite this, research on crocodylian acoustic signalling remains infrequent, with methodologies and terminology varying widely across studies.

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny. [PDF]

open access: yesJ Anat
Extant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in
