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 ...

Interaction Between Age and Individual Heterogeneity Shapes Breeding Probability in a Long-Lived Marine Ectotherm. [PDF]

open access: yesEcol Evol
Using a 52‐year dataset on captive green turtles, our study reveals that individual quality and age are the primary drivers of reproductive patterns. We found that high‐quality turtles bred more consistently throughout their lives and that females maintained a high reproductive value into old age despite evidence of physical aging.

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 ...

Review of the tetrapod skull-neck boundary: implications for the evolution of the atlas-axis complex. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT This review describes variation in modern and fossil occiput–atlas–axis complex anatomy of total group Tetrapoda with the aim of documenting the range of structural variation throughout their evolutionary history to establish grounds for comparison of the complex between tetrapod clades.

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 ...
