Effects of Incubation and Rearing Temperatures on Caiman latirostris Growth [PDF]

, 2010
Different studies found that incubation temperature has an influence on the size of Caiman latirostris hatchlings and determines their gonadal sex. Experimental manipulations revealed that the effects of temperature on growth are independent of sex ...

Population genetic analysis of Caiman crocodilus (Linnaeus, 1758) from South America

Genetics and Molecular Biology, 2006
The genetic structure of Caiman crocodilus was investigated using a 1085 bp mtDNA fragment of the cytochrome b gene. Inferences were based on 125 individuals from nine localities in Peru, Brazil and French Guiana.

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 ...

Population ecology of the spectacled caiman (Caiman crocodilus) in the Apaporis River middle basin

Ecosphere, 2021
Population ecology studies on spectacled caimans (Caiman crocodilus) in Colombia have been few and far between with many covering short periods and defining population parameters based on relative indices (i.e., individuals/km).

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.

Lingual Salt Glands in Crocodylus acutus and C. johnstoni and Their Absence from Alligator mississipiensis and Caiman crocodilus [PDF]

, 1982
1. Lingual salt glands, secreting hyperosmotic Na/K solutions in response to methacholine, are present in Crocodylus acutus and C. johnstoni but apparently absent from the alligatorids, Alligator mississipiensis and Caiman crocodilus. 2.
