Comparison of the Single-Cell Immune Landscape of Testudines From Different Habitats

open access: yesCells, 2022
Testudines, also known as living fossils, have evolved diversely and comprise many species that occupy a variety of ecological niches. However, the immune adaptation of testudines to the different ecological niches remains poorly understood.

Middle Ear Cavity Morphology Is Consistent With an Aquatic Origin for Testudines [PDF]

open access: yesPLoS ONE, 2013
The position of testudines in vertebrate phylogeny is being re-evaluated. At present, testudine morphological and molecular data conflict when reconstructing phylogenetic relationships.

Aging dynamics in captive sea turtles reflect conserved life-history patterns across the testudine phylogeny [PDF]

open access: yesCommunications Biology
Recent work has shown testudines can escape actuarial senescence for extended periods. However, understanding how the interplay between somatic aging and reproductive investment in highly fecund, long-lived ectotherms align with broader phylogenetic ...

Detection of zoonotic bacteria in wild Australian freshwater turtles. [PDF]

open access: yesAust Vet J
Freshwater turtles are long‐lived, abundant components of Australian aquatic ecosystems, yet little is known about the diversity and prevalence of zoonotic bacteria they may carry. In this study, we conducted one of the most comprehensive surveys to date of zoonotic microorganisms associated with wild Australian freshwater turtles.

Cladistic Relationships and Landscape Genetics of the Endangered Indian Peacock Softshell Turtle Nilssonia hurum (Gray, 1830): Implications for Strategic Conservation Planning [PDF]

open access: yesEcology and Evolution
The endangered Peacock Softshell Turtle Nilssonia hurum (Gray, 1830) has undergone a steep population decline in recent decades because of habitat loss and anthropogenic pressures, highlighting the urgent need for scientific intervention to ensure its ...

Spinal Deformities in Wild Reptiles: A Systematic Review and Meta-Analysis [PDF]

open access: yesBiology
Spinal deformities—such as kyphosis, scoliosis, and lordosis—are observed across all major vertebrate groups. Reports in wild reptiles are increasing but are mainly published in natural history notes as curiosities, with little exploration of their ...

Comparison of four different protocols using levobupivacaine for spinal anesthesia in red-footed tortoises (Chelonoidis carbonarius) [PDF]

open access: yesOpen Veterinary Journal
Background: The popularity of tortoises kept in captivity is increasing and has caused concern regarding the necessity to establish safe and straightforward anesthesia for those reptiles.

Mitochondrial DNA and Distribution Modelling Evidenced the Lost Genetic Diversity and Wild-Residence of Star Tortoise, Geochelone elegans (Testudines: Testudinidae) in India

open access: yesAnimals, 2022
The Indian star tortoise (Geochelone elegans) is a massively traded animal in South Asia. To mitigate this risk, the conservation agencies recommended guidelines to safeguard this charismatic species in nature.

A new model of forelimb ecomorphology for predicting the ancient habitats of fossil turtles

open access: yesEcology and Evolution, 2021
Various morphological proxies have been used to infer habitat preferences among fossil turtles and their early ancestors, but most are tightly linked to phylogeny, thereby minimizing their predictive power. One particularly widely used model incorporates
