Répteis do município de Duque de Caxias, Baixada Fluminense, Rio de Janeiro, Sudeste do Brasil

Biotemas, 2010
O município de Duque de Caxias está situado na Baixada Fluminense do Rio de Janeiro, nos domínios da Mata Atlântica Ombrófila Densa. A herpetofauna local foi bastante estudada na década de 40, entretanto, o inventário da região nunca foi realizado ...

Population structure of the broad-snouted caiman (Caiman latirostris) in natural and man-made water bodies associated with a silvicultural landscape [PDF]

, 2016
The broad-snouted caiman (Caiman latirostris) is a South American crocodilian with a wide geographical distribution. Water bodies originally occupied by the species have suffered extreme anthropogenic pressure; however, the broad-snouted caiman has a ...

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

Conservation Science and Practice, EarlyView.
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, EarlyView.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.
