Reproducción en cautiverio de Crocodylus moreletii en Tabasco, México [PDF]

Revista Mexicana de Biodiversidad, 2011
Entre 1990 y 1993 se estudió la reproducción de Crocodylus moreletii en cautiverio, con 27 machos y 109 hembras. Las hembras resultaron en longitud hocico-cloaca (LHC) más grandes (60 a 140 cm) que lo previamente conocido.

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 ...

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 ...

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.

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

'Ear stones' in crocodylians: a cross-species comparative and ontogenetic survey of otolith structures. [PDF]

R Soc Open Sci, 2022
The vestibular system of the inner ear is a crucial sensory organ, involved in the sensation of balance and equilibrium. It consists of three semicircular canals that sense angular rotations of the head and the vestibule that detects linear acceleration ...

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.
