Amphibians and Reptiles Exhibit Different Ecological and Evolutionary Spatial Patterns in the Amazon Basin

Ecology and Evolution, Volume 15, Issue 3, March 2025.
This study investigates the spatial variability of ecological and evolutionary patterns in amphibian and reptile lineages within the Amazon Basin. Our findings highlight distinct diversity patterns across lineages and ecoregions. ABSTRACT Understanding spatial variability in ecological and evolutionary patterns is key to Amazonian biodiversity ...

Levantamento de ninhos de jacarés em savanas inundáveis, Brasil. [PDF]

, 2011
As planícies de inundação ocorrem no Brasil e em outras áreas na América do Sul. Algumas dessas são imensas, como é o caso do Pantanal, do "cerrado" no Estado de Rondônia e das Ilhas do Bananal, mas a maioria se espalha entre mosaicos ao longo de rios ...

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

Journal 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.

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

Journal 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)

The 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.

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

Zoologia (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.

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

, 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.

First evidence for a latitudinal body mass effect in extant Crocodylia and the relationships of their reproductive characters [PDF]

, 2020
Relationships between distribution patterns and body size have been documented in many endothermic taxa. However, the evidence for these trends in ectotherms generally is equivocal, and there have been no studies of effects in crocodylians specifically ...
