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.

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 ...

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 ...

Adaptive evolution of major histocompatibility complex class I immune genes and disease associations in coastal juvenile sea turtles

open access: yesRoyal Society Open Science, 2022
Characterizing polymorphism at the major histocompatibility complex (MHC) genes is key to understanding the vertebrate immune response to disease. Despite being globally afflicted by the infectious tumour disease fibropapillomatosis (FP), immunogenetic ...

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.
