Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

SOS Cocodrilo Tampico: First‐responder actions to human–crocodile interactions in Northeastern Mexico

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Grupo S.O.S. Cocodrilo Tampico (GSOS‐T), a multi‐agency response team in Tampico, Mexico, documented four human–crocodile interactions with Crocodylus moreletii between 2021 and 2022—two fatal, two non‐fatal—revealing that homeless adults face the greatest risk.

Filogeografia del cocodrilo aguja (Crocodylus acutus) en Colombia basado en secuencias de ADN mitocondrial [PDF]

, 2016
El cocodrilo americano (Crocodylus acutus), fue un habitante natural de hábitats acuáticos de gran parte del neotrópico. Sin embargo, actividades humanas han impactado severamente sus poblaciones en todo el rango distribucional.

Density Estimates of Endangered Endemic Rodents Suggest Broader Impacts of Invasive Burmese Pythons Following a Category 4 Hurricane in the Florida Keys

Biological Diversity, Volume 3, Issue 2, Page 88-98, June 2026.
Density estimates of two endangered rodent subspecies, endemic to Key Largo, Florida, USA. These findings illustrate the contrasting dynamics of two native species associated with the prevalence of invasive Burmese pythons and global change. The woodrats' decline emphasizes its potential risk of extinction as global change continues to impact island ...

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.

Exploring the morphological variation of the hybrids between Crocodylus acutus and Crocodylus moreletii in the Mexican Caribbean through a 2D geometrics morphometric approach [PDF]

, 2023
Hybridization between species has been a controversial topic and it has attracted the attention of different areas in evolutionary biology. In México, this process is present in two crocodile species, Crocodylus acutus and Crocodylus moreletii.
