A genomic framework to assist conservation breeding and translocation success: A case study of a critically endangered turtle

Conservation Science and Practice, Volume 6, Issue 10, October 2024.
Conservation breeding programs often follow six stages proposed by Dick Frankham and colleagues. Although this framework is useful, it is challenging for conservation managers to understand the value of using genetic data for their management actions. Here, we aim to assist managers to incorporate genetic and genomic data into actionable conservation ...

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

Chondrocranial anatomy of Testudo hermanni (Testudinidae, Testudines) with a comparison to other turtles

Journal of Morphology, Volume 285, Issue 7, July 2024.
Histology‐based 3D reconstructions of the chondrocrania (blue), palatoquadrates (purple), and columellae (yellow) of a younger (top) and an older (below) specimen of Hermann's tortoise, Testudo hermanni (Testudines), in ventral views. The first vertebra (green) is partially reconstructed. Based on Figure 3.

Sex chromosome evolution in the clam shrimp Eulimnadia texana

Invertebrate Biology, Volume 143, Issue 2, June 2024.
Abstract Sex chromosome degeneration is documented in various animal taxa and is predicted to be due, in part, to a buildup of transposable elements (TE) on the non‐recombining sex chromosome (Y in mammals and W in many crustaceans). Recombination in XX (or ZZ) individuals is predicted to reduce the buildup of TEs on the X (Z), but because there are no
