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 ...

In vitro evaluation of synergistic activity between ciprofloxacin and broad snouted caiman serum against Escherichia coli [PDF]

, 2015
The in vitro synergistic activity between ciprofloxacin and serum of broad snouted caiman on Escherichia coli was studied. The estimated MIC value of ciprofloxacin was 0.0188 Μg/ml, and two assays of kill curve during 5 hours were performed: the first ...

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 ...

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.

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 ...

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 ...
