A Taxa de conversão do alimento (FCR) do Caiman latirostris é mais eficiente a temperaturas mais elevadas [PDF]

open access: yes, 2009
The effects of temperature on the growth of Caiman latirostris were investigated in order to evaluate the efficiency of food conversion at 29 and 33°C. Sixty-eight captive raised animals, two months old, taken from four nests, were used.

Trifold origin of the reptilian ear ossicle and its relation to the evolutionary modification of the temporal skull region

open access: yesJournal of Anatomy, Volume 246, Issue 3, Page 402-414, March 2025.
The columella‐complex in reptile middle ears involves the footplate, columella shaft, and extracolumella. The latter is partly of quadrate developmental origin, whereas the footplate derives from the mesodermal otic capsule, the shaft and another part of the extracolumella from the hyoid arch.

Histological and immunohistochemical study of the ovaries and oviducts of the juvenile female of Caiman latirostris (Crocodilia: Alligatoridae)

open access: yesZoologia (Curitiba), 2015
The purpose of this study was to examine the ovaries and the oviduct of juvenile females of the broad-snouted caiman, Caiman latirostris (Daudin, 1802), using light microscopy, histochemical and immunocytochemical techniques.

Gharial acoustic signaling: Novel underwater pops are temporally based, context‐dependent, seasonally stable, male‐specific, and individually distinctive

open access: yesJournal of Anatomy, Volume 246, Issue 3, Page 415-443, March 2025.
Male gharials (Gavialis gangeticus) produce loud underwater POPs by rapid jaw clapping 1–3×. POPs are temporally based, context‐dependent, seasonally stable, and individually distinctive. The bulbous, cartilaginous “ghara” atop the snout is a sexually dimorphic unique feature.

Biomechanical modeling of musculoskeletal function related to the terrestrial locomotion of Riojasuchus tenuisceps (Archosauria: Ornithosuchidae)

open access: yesThe Anatomical Record, Volume 308, Issue 2, Page 369-393, February 2025.
Abstract Riojasuchus tenuisceps was a pseudosuchian archosaur from the Late Triassic period in Argentina. Like other ornithosuchids, it had unusual morphology such as a unique “crocodile‐reversed” ankle joint, a lesser trochanter as in dinosaurs and a few other archosaurs, robust vertebrae, and somewhat shortened, gracile forelimbs.

Ultraviolet Radiation on Innate Immunity and Growth of Broad‐Snouted Caiman ( Caiman latirostris ): Implications for Facilities Design [PDF]

open access: yes, 2011
Sunlight is a key environmental factor in almost all ecosystems, and it is necessary for many physiological functions. Many vertebrates require ultraviolet radiation (UV) to perform different physiological processes.

Integrative paleophysiology of the metriorhynchoid Pelagosaurus typus (Pseudosuchia, Thalattosuchia)

open access: yesThe Anatomical Record, Volume 308, Issue 2, Page 394-411, February 2025.
Abstract Paleophysiology is an emergent discipline. Organismic (integrative) approaches seem more appropriate than studies focusing on the variation of specific features because traits are tightly related in actual organisms. Here, we used such an organismic approach (including lifestyle, thermometabolism, and hunting behavior) to understand the ...
