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

Journal 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.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

The Bulletin of the Ecological Society of America, Volume 107, Issue 2, April 2026.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

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 ...

Efecto de los llamados preeclosionales de Crocodylus moreletii en la duración y el número de eclosiones

Acta Universitaria, 2019
Diferentes nidadas ex situde Crocodylus moreletiise sometieron a sesiones de playbacks. Estos variaron con base en la vocalización que emiten, ya sea al inicio o al final del proceso de eclosión, así como en la tasa de repetición (rápida o lenta).

Conquering the crush: A novel tool for holding crocodilian jaws open

Wildlife Society Bulletin, Volume 48, Issue 3, September 2024.
Crocodilians possess the strongest bite force of all extant animals, and this jaw‐closing pressure poses a challenge and safety risk for people working with them. We designed and tested a device for holding alligator jaws open that allows for safe positioning within the mouth and is adaptable to both widen and collapse the gape of the mouth.

Genomic and environmental insights and conservation challenges for two hybridizing iconic crocodile species across Mexico: Crocodylus acutus and C. moreletii

Animal Conservation, Volume 27, Issue 3, Page 308-323, June 2024.
Understanding hybridization is key for conservation of wild species, yet it is still a controversial issue in conservation. We discern geographic and temporal patterns of introgression, migration, and demography for Crocodylus acutus, C. moreletii, and their hybrid lineages.

Digestive proteases of Morelet’s crocodile (Crocodylus moreletii) in three life stages

Revista de Biología Tropical
Introduction: Morelet’s crocodile (Crocodylus moreletii) is a species distributed in the Mexican southeast and threatened due to multiple pressures. Objective: To characterize the digestive proteases in the acid phase (stomach) and alkaline phase (intestine) of three life stages of C. moreletii in captivity (hatchling, juvenile, and adult).
