Observations on nests of Crocodylus moreletii in San Luis Potosí, Mexico Observaciones sobre nidos de Crocodylus moreletii en San Luis Potosí, México

Revista Mexicana de Biodiversidad, 2011
Nesting ecology of Morelet's crocodile (Crocodylus moreletii) has been documented since 1940. However, only 2 nests constructed on floating vegetation have been recorded.

Duración y éxito de eclosión en diferentes tamaños de nidadas de Crocodylus moreletii (Crocodylia: Crocodilidae) [PDF]

Hidrobiológica, 2018
Background. The Crocodylia begin their life by overcoming the incubation stage with group hatching. Incubation temperature is important for the development of the embryos and the duration of the hatching process, during which they emit sounds. Goals. The

Variabilidad genética de poblaciones en cautiverio de Crocodylus moreletii (Crocodylia: Crocodylidae) mediante el uso de marcadores microsatelitales Genetic variability in captive populations of Crocodylus moreletii (Crocodylia: Crocodylidae) using microsatellites markers

Revista de Biología Tropical, 2012
Crocodylus moreletii representa un emblema para los ecosistemas tropicales de México pero actualmente está amenazada por extinción. Sorprendentemente, hay una falta de información de su constitución genética, que debe ser evaluada para un manejo ...

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

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.

Neuroanatomy of the crocodylomorph Portugalosuchus azenhae from the late cretaceous of Portugal. [PDF]

J Anat, 2023
Detailed braincase anatomical description and neuroanatomical study of Portugalosuchus azenhae, from the Cenomanian (Late Cretaceous) of Portugal. Abstract We present the first detailed braincase anatomical description and neuroanatomical study of Portugalosuchus azenhae, from the Cenomanian (Late Cretaceous) of Portugal.

Cave-dwelling crocodiles of Central Belize

International Journal of Speleology, 2023
We provide the results on the first systematic effort to study cave-dwelling crocodiles in central Belize. For nearly three decades, managers at Runaway Creek Nature Reserve have frequently observed crocodile tracks and trackways in caves, while ...

Saurocoría en cocodrilos no favorece la dispersión y viabilidad de semillas

Acta Biológica Colombiana, 2021
La dispersión de semillas por reptiles (saurocoría) ha recibido atención recientemente y se ha reportado el consumo de frutos y semillas en cocodrilianos, actuando como potenciales dispersores de semillas.
