Temperature variation in nests of Caiman crocodilus (Crocodylia: Alligatoridae)

open access: yesActa Herpetologica, 2007
Caiman crocodilus is a widely distributed species in the Neotropics; however, studies of incubation temperatures in wildlife are uncommon. Incubation temperature in four nests of Caiman crocodilus were measured with a digital thermometer, in the National

Hepatozoon caimani in Caiman crocodilus yacare (Crocodylia, Alligatoridae) from North Pantanal, Brazil [PDF]

open access: yesRevista Brasileira de Parasitologia Veterinária, 2017
Hepatozoon species are the most common intracellular hemoparasite found in reptiles. Hepatozoon caimani, whose vectors are Culex mosquitoes, has been detected in a high prevalence among caimans in Brazil by blood smears examinations.

Clutch size of Caiman latirostris (Crocodylia: Alligatoridae) varies on a latitudinal gradient [PDF]

open access: yes, 2009
The distribution of the Broad-Snouted Caiman (Caiman latirostris) ranges from 5°S to 32°S. Thus, caiman populations are exposed to different climatic conditions, and this latitudinal gradient could affect aspects of their reproduction.

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia. [PDF]

open access: yesJ Anat
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

Cloacal mycobiota in wild females of Caiman latirostris (Crocodylia: Alligatoridae)

open access: yesRevista Mexicana de Biodiversidad, 2013
There are few reports of cloacal mycobiota on wild reptiles, and in particular, fungal presence and functionin Caiman latirostris remains unknown. Our objective was to describe the fungal community present in the cloaca ofwild female broad-snouted caimans during their reproductive season determine whether the number of fungi has somerelationship with ...

Roars, Rumbles, and Resonance: A Systematic Review and Meta-Analysis of Crocodylian Acoustic Signals. [PDF]

open access: yesEcol Evol
Crocodylians are highly vocal reptiles, possessing a complex acoustic signalling system including vocal and non‐vocal signals used for courtship, mating, mediating conflict, and providing maternal care. Despite this, research on crocodylian acoustic signalling remains infrequent, with methodologies and terminology varying widely across studies.
