Environmental DNA-based biomonitoring of Cuban Crocodylus and their accompanying vertebrate fauna from Zapata Swamp, Cuba [PDF]

Scientific Reports, 2023
Crocodylians globally face considerable challenges, including population decline and extensive habitat modification. Close monitoring of crocodylian populations and their habitats is imperative for the timely detection of population trends, especially in

Hybridization and Immunology in Animals: A Review. [PDF]

Ecol Evol
Hybridization 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.

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

The velar chord and dynamic integration of the gular valve in crocodylians. [PDF]

Anat Rec (Hoboken)
Crocodilians have a unique gular valve that forms a seal between the oral cavity and the pharynx. The gular valve has traditionally been treated as two parts: a mobile ventral flap associated with the tongue and a fixed dorsal velum palatini. This work describes a connective tissue band, the velar chord, which functionally integrates the two parts of ...

Illegal trade of crocodylians in Colombia: Spatiotemporal dynamics and implications on conservation efforts

Conservation Science and Practice
Crocodylian conservation efforts have encountered significant obstacles from species overhunting to negative local perception. While conservation strategies such as sustainable use have helped the recovery of several crocodylian species around the world,
