Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Population genetics implications for the conservation of the Philippine Crocodile Crocodylus mindorensis Schmidt, 1935 (Crocodylia: Crocodylidae)

open access: yesJournal of Threatened Taxa, 2014
Limited information is available on the Philippine Crocodile, Crocodylus mindorensis, concerning levels of genetic diversity either relative to other crocodilian species or among populations of the species itself.

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

open access: yesThe Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

A genetic linkage map for the saltwater crocodile (Crocodylus porosus)

open access: yesBMC Genomics, 2009
Background Genome elucidation is now in high gear for many organisms, and whilst genetic maps have been developed for a broad array of species, surprisingly, no such maps exist for a crocodilian, or indeed any other non-avian member of the Class Reptilia.

Human–crocodilian interactions in Latin America and the Caribbean region

open access: yesConservation Science and Practice, 2021
Mitigating harmful interactions with wildlife requires an understanding of the interactions between predators, domesticated animals and humans. Large‐scale transformations of crocodilian habitats across the Latin America and Caribbean region, alongside ...

First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

open access: yesThe Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...

A check-list of the pentastomid parasites of crocodilians and freshwater chelonians

open access: yesOnderstepoort Journal of Veterinary Research, 2006
Based on published records and own data a summary is given of the geographical distribution of the currently known species of pentastomid parasites infecting crocodiles and alligators, as well as freshwater chelonians.

Crafter preferences for alligator leather in an online hypothetical and real discrete choice experiment

open access: yesJournal of the Agricultural and Applied Economics Association, EarlyView.
Abstract A decrease in the price of alligator hides has led to identifying new markets for wild alligator leather. This study investigates crafters' preferences for using alligator leather as a crafting material. In an online survey, we implement hypothetical and real Discrete Choice Experiments to assess crafters' willingness to pay for alligator ...

Volume of the crocodilian brain and endocast during ontogeny. [PDF]

open access: yesPLoS ONE, 2017
Understanding complex situations and planning difficult actions require a brain of appropriate size. Animal encephalisation provides an indirect information about these abilities.
