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

Wildlife Pathogens and Zoonotic Disease Risk Assessment in Vietnam: A Wildlife Trade Hotspot. [PDF]

Transbound Emerg Dis
Vietnam is a wildlife trade hotspot presenting multiple high‐risk interfaces for pathogen spillover from wildlife to humans. However, the zoonotic disease risk remains poorly characterized in the country and needs to be assessed to better inform policy dialog and legislative reforms.

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 ...

Epidermal scale growth, allometry and function in non-avian dinosaurs and extant reptiles. [PDF]

J Anat
Scale shapes in non‐avian dinosaurs and extant reptiles are mostly retained through growth. However, positive scale allometry and proportional differences in scale breadth are also detected, which are likely associated with changing body proportions. Based on their generally conserved morphology and impracticality for visual display, the enlarged size ...

Distribución y estado de conservación del cocodrilo americano (Crocodylidae: Crocodylus acutus) en El Salvador

Cuadernos de investigación UNED, 2022
Introducción: El cocodrilo americano (Crocodylus acutus) es un depredador de alto nivel y puede ser considerado una especie clave en sus ecosistemas. Aunque la especie se ha estudiado a menudo en otros lugares, hay poca información sobre su distribución
