Serum concentrations of corticosterone and sex hormones and their relationship in farmed Morelet’s crocodile (Crocodylus moreletii)

Revista Colombiana de Ciencias Pecuarias, 2022
Background: Crocodile farming aims to produce high-quality skins from captive crocodilians. Captivity usually exposes the animals to stressful conditions, resulting in increased serum corticosterone (CORT) levels that correlate negatively with those of ...

High levels of population genetic differentiation in the American crocodile (Crocodylus acutus). [PDF]

PLoS One, 2020
The American crocodile (Crocodylus acutus) is a widely distributed species across coastal and brackish areas of the Neotropical region of the Americas and the Greater Antilles. Available information on patterns of genetic differentiation in C.

CHARACTERIZATION OF MORPHOLOGICAL TRAITS OF COMMERCIAL INTEREST IN THE MORELET'S CROCODILE (Crocodylus moreletii)

Tropical and Subtropical Agroecosystems, 2011
Crocodylus moreletii is a species of commercial interest based on its skin. In this study, five morphological traits of commercial interest were characterized in 125 captivity-raised specimens of C.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia. [PDF]

J Anat
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

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

Ecol 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.

Hybridization and Immunology in Animals: A Review. [PDF]

Ecol Evol
Hybridization can reshape immune function by introducing novel genetic variation and combining parental immune traits. Across animal taxa, this process may influence resistance, tolerance, and pathogen dynamics, with important implications for disease ecology and One Health.

How many fathers? Study design implications when inferring multiple paternity in crocodilians. [PDF]

Ecol Evol, 2022
Up to ten males have been reported to sire clutches of crocodilian eggs but review of the underlying study designs raised questions of potential upward bias of inferred sire numbers. Using a known dataset from 1:1 male:female matings, an impossible 7 sires were inferred by limiting the genotypic information using a particular statistical package ...

The comparative energetics of the turtles and crocodiles. [PDF]

Ecol Evol, 2022
This paper discusses patterns in Dynamic Energy Budget parameters and implied traits that we found for turtles and crocodiles. We explain, for instance, why the proportionality of weight at birth with the square root of ultimate weight points to problems with water loss and nitrogen‐waste accumulation.
