Geographic distribution and conservation status of Caiman latirostris (Crocodylia, Alligatoridae) in Uruguay [PDF]

Phyllomedusa: Journal of Herpetology, 2006
Populations of Caiman latirostris are known to occur in Uruguay but their geographic distribution remains uncertain. This work presents an update of the species distribution and conservation status in Uruguay.

Hematology and Blood Biochemistry of Young Healthy Broad-Snouted Caimans (Caiman latirostris)

Journal of Herpetology, 2011
Abstract Caiman latirostris (Broad-Snouted Caiman) is widely distributed in wetlands and rivers of South America. Hematological and blood chemistry reference values are necessary for detecting the effects of environmental, infectious, parasitic, or toxicological stress on C. latirostris health.

Allometry of reproduction in broad-snouted caiman (Caiman latirostris)

Brazilian Journal of Biology
In the present study regression equations are established between broad-snouted caiman (Caiman latirostris) captive reproductive females snout-vent length (SVL) and body mass (BM) and the following clutch characteristics: egg mass, egg "length" (maximal ...

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

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

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, 2021
AbstractIn 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 caimans (Caiman latirostris) in response to acute warming within a preferred body temperature ...

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, EarlyView.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

BASELINE DATA ON HEMATOLOGICAL AND BIOCHEMICAL PARAMETERS FOR THE USE OF WILD JUVENILE BROAD-SNOUTED CAIMAN (Caiman latirostris) AS BIOINDICATORS IN ATLANTIC FOREST, SOUTHEASTERN BRAZIL

, 2022
Crocodilians are considered as good indicators of ecosystem health since environmental conditions will influence them at individual (body condition and health parameters) and populational levels (population dynamics and behavior). Despite that, there are

Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

Journal of Anatomy, EarlyView.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Comparison of complement system activity amongst wild and domestic animals

Acta Herpetologica, 2020
Multiple mechanisms have evolved for the defensive recognition of foreign components, such as microorganisms. The majority of immunological studies with vertebrates have been focused on endothermic species, and relatively little attention has been ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
