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 Cytogenetic Map of the Nile Crocodile (Crocodylus niloticus, Crocodylidae, Reptilia) with Fluorescence In Situ Localization of Major Repetitive DNAs. [PDF]

Int J Mol Sci, 2022
Tandemly arranged and dispersed repetitive DNA sequences are important structural and functional elements that make up a significant portion of vertebrate genomes. Using high throughput, low coverage whole genome sequencing followed by bioinformatics analysis, we have identified seven major tandem repetitive DNAs and two fragments of LTR ...

Clustering crocodylian dental morphology: Insights into functional adaptations, diet, and ontogeny. [PDF]

J Anat
Extant crocodylians may be divided into five clusters based on the residuals of four linear dental measurements (y‐axes) and their variation along the jaw (x‐axes). These clusters correlate to snout shape, prey preference, and feeding ecology, particularly prey size and the degree of processing necessary. Multiple families and subfamilies were found in

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.

Urban-Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador. [PDF]

Ecol Evol
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...

A new Crocodyloidea from the middle Eocene of Zamora (Duero Basin, Spain). [PDF]

Anat Rec (Hoboken)
Abstract The eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus.

Wild Encounters: Analyzing Human-Animal Interactions in British and Irish Association of Zoos and Aquariums Facilities. [PDF]

Zoo Biol
We investigated the quantity and diversity of animal–visitor interactions in BIAZA‐accredited facilities, finding 740 opportunities for interactions across a range of contexts including walkthroughs and handling. Meet and greets were the most offered and were influenced by the number of individual animals, cost of interaction, and animal popularity ...

Asian crocodile poaching: A review of molecular techniques developed for forensic identification

Journal of Forensic Science and Medicine, 2022
Crocodiles, gharials and alligators (order Crocodilia), are aquatic reptiles that live in the tropics of Asia, America, Africa, and Australia. Asian countries such as India, Indonesia, Malaysia, and tropics of Australia are the stronghold of the family ...

[Population ecology of Crocodylus acutus (Reptilia: Crocodylidae) in Palmasola lagoon, Oaxaca, Mexico].

Revista de biologia tropical, 2014
Population ecology of Crocodylus acutus (Reptilia: Crocodylidae) in Palmasola lagoon, Oaxaca, Mexico. Abundance and population structure are important parameters to evaluate and compare the conservation status of a population over time in a given area. This study describes the population abundance and structure of Crocodylus acutus in Palmasola lagoon,
