The taxonomic status of Farlowella colombiensis Retzer & Page 1997 with comments on species of the F. acus species group (Loricariidae: Loricariinae)

Journal of Fish Biology, Volume 107, Issue 5, Page 1669-1684, November 2025.
Abstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such

From eggs to hatchlings: nest site taphonomy of american crocodile (Crocodylus acutus) and broad snouted caiman (Caiman latirostris) [PDF]

, 2017
Nesting behaviors of extant vertebrates can serve as taphonomic models for interpreting extinct archosaurian reproduction. Past studies have examined birds with open nests and nest-bound young and tortoises with buried nests and precocial young.

“Are there caimans here?” Influence of multiple drivers on local ecological knowledge about an apex predator

Frontiers in Amphibian and Reptile Science
IntroductionLocal Ecological Knowledge (LEK) regarding apex predators, such as crocodilians, is crucial for understanding human–wildlife dynamics and supporting conservation strategies.

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

Wildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Osteohistological signal from the smallest known phytosaur femur reveals slow growth and new insights into the evolution of growth in Archosauria

Journal of Anatomy, Volume 247, Issue 3-4, Page 556-575, September/October 2025.
The paucity of small, skeletally immature individuals representing the earliest ontogenetic stages of extinct archosaurs complicates our understanding of the growth dynamics within and between species. The opportune finding of the smallest phytosaur femora reveals slow growth, a surprising signal considering that larger phytosaurs in North America have

Evolution of growth strategy in alligators and caimans informed by osteohistology of the late Eocene early‐diverging alligatoroid crocodylian Diplocynodon hantoniensis

Journal of Anatomy, Volume 247, Issue 1, Page 165-178, July 2025.
Living alligatoroids (alligators and caimans) share osteohistological features and display similar overall growth rates. However, it is unclear if these shared patterns are the result of convergent responses or reflect an ancestral condition. In this study, we histologically sampled nine femora of the fossil alligatoroid Diplocynodon hantoniensis to ...

Systematization, Description and Territory of The Middle and Rostral Cerebral Arteries in Broad-Snouted Caimans (Caiman latirostris)

Acta Scientiae Veterinariae, 2018
Background: Information on the arterial vascularization of the broad-snouted caimans’ brain (Caiman latirostris), a specie from the Brazilian fauna, is inexistent and the literature consulted yielded only one description about the development of embryonic circulation and post-birth cerebrovascular alterations in the brain of three caymans.

A new Crocodyloidea from the middle Eocene of Zamora (Duero Basin, Spain)

The Anatomical Record, Volume 308, Issue 6, Page 1692-1706, June 2025.
Abstract The eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus.

Effects of climatic conditions on sex ratios in nests of broad‐snouted caiman

Journal of Zoology, 2014
AbstractCaiman latirostris has temperature‐dependent sex determination and is potentially susceptible to environmental temperature fluctuations and, thus, to the global climate change phenomena. Considering the potential consequences of increasing temperatures for Ca.
