Phylogenetic Relationships of the Asian Box Turtles of the Genus Cuora Sensu Lato (Reptilia: Bataguridae) Inferred from Mitochondrial DNA Sequences
ZOOLOGICAL SCIENCE 19: 1305–1312 (2002) 2002 Zoological Society of Japan Phylogenetic Relationships of the Asian Box Turtles of the Genus Cuora sensu lato (Reptilia: Bataguridae) Inferred from Mitochondrial DNA Sequences Masanao Honda1*†, Yuichirou Yasukawa1, Ren Hirayama2 and Hidetoshi Ota1 1Tropical Biosphere Research Center, University of the Ryukyus, Nishihara, Okinawa 903-0213, Japan 2Faculty of Information, Teikyo Heisei University, Ichihara, Chiba 290-0193, Japan ABSTRACT—Phylogenetic relationships of the genus Cuora sensu lato (Cuora sensu stricto and Cisto- clemmys) and other testudinoid genera were inferred from variations in 882 base positions of mitochondrial 12S and 16S rRNA genes. Results yielded a robust support to the monophyly of a group (Cuora group) consisting of Cuora sensu lato and the monotypic Pyxidea. Within the Cuora group, the continental Cuora (sensu stricto) and the two subspecies of Ci. flavomarginata constituted two well-supported monophyletic groups. Distinctly small interspecific genetic distances in the former groups suggested that in the continent speciations in Cuora took place much later than the primary divergences in the Cuora group, or speciations in other related genera, such as Mauremys. Our analyses failed to provide a substantial support to the monophyly of any other combinations of taxa within the Cuora group, including Cuora in broad and strict senses, and Cistoclemmys as consisting of Ci. galbinifrons and Ci. flavomarginata. Besides these, our results also suggested the non-monophyly for the Batagurinae and the Geoemydinae, and sister relation- ships of the Bataguridae with Testudinidae rather than with the Emydidae.

Chelonian Perivitelline Membrane-Bound Sperm Detection: a New Breeding Management Tool
Zoo Biology 35: 95–103 (2016) RESEARCH ARTICLE Chelonian Perivitelline Membrane-Bound Sperm Detection: A New Breeding Management Tool Kaitlin Croyle,1,2 Paul Gibbons,3 Christine Light,3 Eric Goode,3 Barbara Durrant,1 and Thomas Jensen1* 1San Diego Zoo Institute for Conservation Research, Escondido, California 2Department of Biological Sciences, California State University San Marcos, San Marcos, California 3Turtle Conservancy, New York, New York Perivitelline membrane (PVM)-bound sperm detection has recently been incorporated into avian breeding programs to assess egg fertility, confirm successful copulation, and to evaluate male reproductive status and pair compatibility. Due to the similarities between avian and chelonian egg structure and development, and because fertility determination in chelonian eggs lacking embryonic growth is equally challenging, PVM-bound sperm detection may also be a promising tool for the reproductive management of turtles and tortoises. This study is the first to successfully demonstrate the use of PVM-bound sperm detection in chelonian eggs. Recovered membranes were stained with Hoechst 33342 and examined for sperm presence using fluorescence microscopy. Sperm were positively identified for up to 206 days post-oviposition, following storage, diapause, and/or incubation, in 52 opportunistically collected eggs representing 12 species. However, advanced microbial infection frequently hindered the ability to detect membrane-bound sperm. Fertile Centrochelys sulcata, Manouria emys,andStigmochelys pardalis eggs were used to evaluate the impact of incubation and storage on the ability to detect sperm. Storage at À20°C or in formalin were found to be the best methods for egg preservation prior to sperm detection. Additionally, sperm-derived mtDNA was isolated and PCR amplified from Astrochelys radiata, C. -

Meyer Building, D-01109 Dresden, Germany 4Corresponding author. E-mail: [email protected] Abstract Estuarine Batagur are among the most critically endangered chelonian species. We assess the taxonomic status of the recently discovered Cambodian relic population of Batagur by phylogenetic analyses of three mitochondrial (2096 bp) and three nuclear DNA fragments (1909 bp) using sequences from all other Batagur species and selected allied geoemydids. Furthermore, we calculated haplotype networks of the mitochondrial cytochrome b gene for Cambodian terrapins, B. affinis, B. baska, and B. kachuga and compare external morphology of estuarine Batagur populations. Genetically, Cambodian Batagur are closely related with, but distinct from B. affinis from Sumatra and the west coast of the Malay Peninsula. Morphologically, Cambodian Batagur resemble the distinctive B. affinis populations from the eastern Malay Peninsula that were not available for genetic study. We suggest that the Batagur populations from the eastern Malay Peninsula and Cambodia represent a new subspecies of B. affinis that once was distributed in estuaries surrounding the Gulf of Thailand (Batagur affinis edwardmolli subsp. -

Classification Order: Testudines Family: Chelydridae Genus: Chelydra Species: serpentina (Linnaeus, 1758) Previous research on Chelydra serpentina (Phillips et al., 1996) acknowledged four subspecies, C. s. serpentina (Northern U.S. and Figure 2.

Recent IUCN m. reclassification of chelonians based on genetic analyses (Rhodin et al., 2010) elevated C. s. rossignonii and C. s. acutirostris to species level and established C. s. osceola as a synonym for C. s. serpentina, thus eliminating subspecies within C. serpentina. Antiquated distinctions between the two formerly recognized North American subspecies were based on negligible morphometric variations between the two populations. Interbreeding in the overlapping range of the two populations was well documented, further discrediting the validity of the subspecies distinction (Feuer, 1971; Aresco and Gunzburger, 2007). Therefore, any emphasis of subspecies differentiation in the ensuing literature should be disregarded. Figure 3.

The species is a morphologi- cally distinctive morphotype, but has so far not been genetically distinguishable from the Aldabra tortoise, and is considered synonymous with that species by many researchers. Captive reared juveniles suggest that there may be a genetic basis for the morphotype and more detailed genetic work is needed to elucidate these relationships. The species is the only living saddle-backed tortoise in the Seychelles islands. It was apparently extirpated from the wild in the 1800s and believed to be extinct until recently purportedly rediscovered in captivity. The current population of this morphotype is 23 adults, including 18 captive adult males on Mahé Island, 5 adults recently in- troduced to Silhouette Island, and one free-ranging female on Cousine Island. Successful captive breeding has produced 138 juveniles to date. -

Mazzotti1 Abstract - Dermatemys mawii (Central American River Turtle), locally known in Belize as the “Hicatee” and in Guatemala and Mexico as Tortuga Blanca, is a large, highly aquatic freshwater turtle that has been extirpated from much of its historical range of southern Mex- ico, northern Guatemala, and lowland Belize. Throughout its restricted range, Dermatemys has been intensely harvested for its meat and eggs and sold in local markets. -
