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.

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Color and Near‐Infrared Reflectance Covary in Distinct Ways Across Taxa [PDF]

open access: yesEcol Evol
Solar reflectance across ultraviolet, visible, and near‐infrared wavelengths was analyzed in integuments and eggs of 322 species. We found consistent positive correlations between UV and visible reflectance, while visible‐NIR associations varied across taxa, with differences in baseline reflectance suggesting structural or compositional influences ...

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 ...

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 ...

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.

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 ...

The complete mitochondrial genome of the endangered Assam Roofed Turtle, Pangshura sylhetensis (Testudines: Geoemydidae): Genomic features and phylogeny.

open access: yesPLoS ONE, 2020
The Assam Roofed Turtle, Pangshura sylhetensis is an endangered and least studied species endemic to India and Bangladesh. The present study decodes the first complete mitochondrial genome of P. sylhetensis (16,568 bp) by using next-generation sequencing.
