The Staurotypus Turtles and Aves Share the Same Origin of Sex Chromosomes but Evolved Different Types of Heterogametic Sex Determination
The Staurotypus Turtles and Aves Share the Same Origin of Sex Chromosomes but Evolved Different Types of Heterogametic Sex Determination Taiki Kawagoshi1, Yoshinobu Uno1, Chizuko Nishida2, Yoichi Matsuda1,3* 1 Laboratory of Animal Genetics, Department of Applied Molecular Biosciences, Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, Japan, 2 Department of Natural History Sciences, Faculty of Science, Hokkaido University, Sapporo, Japan, 3 Avian Bioscience Research Center, Graduate School of Bioagricultural Sciences, Nagoya University, Nagoya, Japan Abstract Reptiles have a wide diversity of sex-determining mechanisms and types of sex chromosomes. Turtles exhibit temperature- dependent sex determination and genotypic sex determination, with male heterogametic (XX/XY) and female heterogametic (ZZ/ZW) sex chromosomes. Identification of sex chromosomes in many turtle species and their comparative genomic analysis are of great significance to understand the evolutionary processes of sex determination and sex chromosome differentiation in Testudines. The Mexican giant musk turtle (Staurotypus triporcatus, Kinosternidae, Testudines) and the giant musk turtle (Staurotypus salvinii) have heteromorphic XY sex chromosomes with a low degree of morphological differentiation; however, their origin and linkage group are still unknown. Cross-species chromosome painting with chromosome-specific DNA from Chinese soft-shelled turtle (Pelodiscus sinensis) revealed that the X and Y chromosomes of S. triporcatus have homology with P. sinensis chromosome 6, which corresponds to the chicken Z chromosome. We cloned cDNA fragments of S. triporcatus homologs of 16 chicken Z-linked genes and mapped them to S. triporcatus and S. salvinii chromosomes using fluorescence in situ hybridization. Sixteen genes were localized to the X and Y long arms in the same order in both species. -
Taxonomy and Phylogeny of the Higher Categories of Cryptodiran Turtles Based on a Cladistic Analysis of Chromosomal Data
Copein, 1983(4), pp. 918-932 Taxonomy and Phylogeny of the Higher Categories of Cryptodiran Turtles Based on a Cladistic Analysis of Chromosomal Data John W. Bickham and John L. Carr Karyological data are available for 55% of all cryptodiran turtle species including members of all but one family. Cladistic analysis of these data, as well as con sideration of other taxonomic studies, lead us to propose a formal classification and phylogeny not greatly different from that suggested by other workers. We recognize 11 families and three superfamilies. The platysternid and staurotypid turtles are recognized at the familial level. Patterns and models of karyotypic evolution in turtles are reviewed and discussed. OVER the past 10 years knowledge of turtle and the relationship between the shell and pel karyology has grown to such an extent vic girdle. In the cryptodires ("hidden-necked" that the order Testudines is one of the better turtles), the neck is withdrawn into the body in known groups of lower vertebrates (Bickham, a vertical plane and the pelvis is not fused to 1983). Nondifferentially stained karyotypes are either the plastron or carapace, whereas in the known for 55% of cryptodiran turtle species pleurodires ("side-necked" turtles) the pelvic and banded karyotypes for approximately 25% girdle is fused to both the plastron and carapace (Bickham, 1981). From this body of knowledge, and the neck is folded back against the body in as well as a consideration of the morphological a horizontal plane. Cope's suborder Athecae variation in the order, we herein present a gen includes only the Dermochelyidae and is no eral review of the cryptodiran karyological lit longer recognized. -

EDWIN R. CADENA1-3, CARLOS M. JARAMILLO1 AND MARIA PARAMO2 ' Center for Tropical Paleoecology and Archeology, Smithsonian Tropical Research Institute, Balboa, Ancon, Panama. 2 Museo Geologico Jose Royo y Gomez, Instituto Colombiano de Geologia y Mineria IINGEOMINAS, Bogota, Colombia. 3 Corresponding Author: [email protected] ABSTRACT: The first fossil record of Kinosternon turtles in South America, from the late Pleistocene (16500 years before present) at the Pubenza locality, Department of Cundinamarca, in the Bogota River basin of Colombia is described. The fossil material is com- posed of an epiplastron, a hypoplastron, a peripheral, two costals, and a neural bone, which suggest an affinity to the Kinosterninae subfamily based upon the absence of an entoplastron and an abdominal scale. The presence of a hinge in the anterior and posterior plastral lobe and a large epiplastron longer than wide indicate an affinity to the genus Kinosternon. The presence of a marked scar for the insertion of the cervico-plastral ligament on the visceral surface of the epiplastron indicates a close relationship to Kinosternon leucostomum and Kinosternon scorpioides. More shell and cranial material must be found in order to define precisely if the Kinosternon of Pubenza corresponds to some extant species, or if it is a new extinct species. KEYWORDS: Kinosternidae, Kinosternon, late Pleistocene, Colombia. INTRODUCTION that it is closely related to the family Dermatemydi- dae (Shaffer etal, 1997; Krenz etal, 2005; Joyce, The turtle family Kinosternidae is endemic to 2007). -

This time period offers a rare chance to observe dramatic climatic changes, such as sudden warming trends. The site is sedimentologically and stratigraphically consistent with the Mascall Formation of the John Day Basin to the north and east of Hawk Rim. Hawk Rim preserves taxa such as canids Cynarctoides acridens and Paratomarctus temerarius, the felid Pseudaelurus skinneri, castorids Anchitheriomys and Monosaulax, tortoises and the remains of both cormorants and owls. -
