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

open access: yesActa 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.

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

open access: yesEnvironmental 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

Impacts of red imported fire ants Solenopsis invicta on survivorship of hatchlings of the broad-snouted caiman Caiman latirostris [PDF]

open access: yes, 2013
Background: Oviparous vertebrate species are often vulnerable to predation by red imported fire ants (RIFAs, Solenopsis invicta) in natural environments. The necrotic action of the venom can cause localized infections, with subsequent effects on survival

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

open access: yesJournal 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

Basal frequency of micronuclei and hematological parameters in the Side-necked Turtle, Phrynops hilarii (Duméril & Bibron, 1835) [PDF]

open access: yes, 2015
The present study aimed to evaluate basaleline frequency of micronuclei (MN) and reference values for hematological values parameters in adult Phrynops hilarii in order to propose this aquatic turtle, broadly distributed in our region, as a biological ...

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.

Broad snouted caiman (Caiman latirostris) growth under different rearing densities

open access: yesAquaculture, 2008
Abstract The effect of density on growth in body mass (BM) and total length (TL) of Caiman latirostris hatchlings raised in small pens (area 0.36 m2), for 3 months, was investigated. Twelve animals from each of three clutches were randomly distributed (1, 2 or 3 individuals) to two replicates at low rearing density (LRD: 0.12 m2/individual), medium ...

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

open access: yesAnais 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

DNA extraction from skins of wild (Hydrochoerus hydrochaeris and Pecari tajacu) and domestic (Sus scrofa domestica) species using a novel protocol. [PDF]

open access: yes, 2012
Sometimes, commercial products obtained from wild animals are sold as if they were from domestic animals and vice versa. At this point of the productive chain, legal control of possible wildlife products is difficult.
