Micronuclei and Nuclear Buds Induced by Cyclophosphamide in Crocodylus moreletii as Useful Biomarkers in Aquatic Environments [PDF]
Animals, 2021 Micronuclei (MN) are used to assess genotoxic exposure, whereas nuclear buds (NBs) have been linked to genotoxic events. Crocodylus moreletii was studied to identify MN and NBs.

Variation in the Diet of Hatchling Morelet’s Crocodile (Crocodylus moreletii) in the Wild [PDF]
AnimalsThe relationship between diet and behavior is essential to understanding an animal’s strategies to obtain food, considering ontogenical changes. In reptiles, there is a relationship between the length of the individual and the size of the prey it ...

N-mixture models provide informative crocodile (Crocodylus moreletii) abundance estimates in dynamic environments [PDF]
PeerJ, 2022 Estimates of animal abundance provide essential information for population ecological studies. However, the recording of individuals in the field can be challenging, and accurate estimates require analytical techniques which account for imperfect ...

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

Integrating molecular, phenotypic and environmental data to elucidate patterns of crocodile hybridization in Belize [PDF]
Royal Society Open Science, 2015 The genus Crocodylus comprises 12 currently recognized species, many of which can be difficult to differentiate phenotypically. Interspecific hybridization among crocodiles is known to occur in captivity and has been documented between some species in ...
