Health Biomarkers of Pesticide Exposure in Rural Populations of Santa Fe, Argentina: Oxidative Stress and Genotoxicity

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...

Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
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

Behavioral thermoregulation in the spectacled caiman (Caiman sclerops) [PDF]

open access: yesBehavior Research Methods & Instrumentation, 1976
This report describes an operant conditioning technique for studying crocodilians. As experimental subjects, crocodilians present some special problems. For example, their size limits direct handling. Further, because they may go for prolonged periods without eating, food probably is not an effective reinforcer.

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

open access: yesJournal 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.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

En ‘Tierra de Caimanes’: imaginarios geográficos, literatura ilustrada y tropicalidad del río Orinoco en las obras de Jules Crevaux (1883) y Jean Chaffanjon (1889)

open access: yesHistoria Crítica, 2023
Objective/context: In France’s second half of the 19th century, magazines such as Le Tour du Monde and illustrated novels were used to promote geographical sciences and educational and political propaganda of the Third Republic and its economic interests

Climatic Niche Modelling Reveals Limited Phylogenetic Niche Conservatism in New World Crocodylians

open access: yesJournal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim Phylogenetic niche conservatism, the tendency of closely related species to retain ancestral ecological traits, has gained considerable interest, yet the lack of integration across independent evaluation methods has hindered our understanding of whether niches are conserved or dynamic.
