E-mail: [email protected] Abstract We review competing taxonomic classifications and hypotheses for the phylogeny of emydine turtles. The formerly rec- ognized genus Clemmys sensu lato clearly is paraphyletic. Two of its former species, now Glyptemys insculpta and G. muhlenbergii, constitute a well-supported basal clade within the Emydinae. However, the phylogenetic position of the oth- er two species traditionally placed in Clemmys remains controversial. Mitochondrial data suggest a clade embracing Actinemys (formerly Clemmys) marmorata, Emydoidea and Emys and as its sister either another clade (Clemmys guttata + Terrapene) or Terrapene alone. In contrast, nuclear genomic data yield conflicting results, depending on which genes are used. Either Clemmys guttata is revealed as sister to ((Emydoidea + Emys) + Actinemys) + Terrapene or Clemmys gut- tata is sister to Actinemys marmorata and these two species together are the sister group of (Emydoidea + Emys); Terra- pene appears then as sister to (Actinemys marmorata + Clemmys guttata) + (Emydoidea + Emys). The contradictory branching patterns depending from the selected loci are suggestive of lineage sorting problems. Ignoring the unclear phy- logenetic position of Actinemys marmorata, one recently proposed classification scheme placed Actinemys marmorata, Emydoidea blandingii, Emys orbicularis, and Emys trinacris in one genus (Emys), while another classification scheme treats Actinemys, Emydoidea, and Emys as distinct genera.

Email: [email protected] The Willow Creek Riparian Preserve (Preserve) is a privately owned 130-acre site located 30 miles east of Kingman, Arizona. The Preserve was formally established in 2007 with the purchase of 10-acres and an agreement with the eastern adjoining private landowner to add an additional 120-acres. The Preserve location was unfenced and wholly accessible by livestock, off-road vehicle use, and hunting. In October of 2008 the Preserve was fenced with volunteer efforts from the local Rotary Club and Boy Scout Troop 66. Additional financial assistance came through a large discount in the cost of fencing materials from Kingman Ace Hardware. A total of 0.5-linear mile of new wildlife friendly fencing (barbless top wire and 18-inches above-ground bottom wire) was installed along the south and west sides and connected to existing Arizona State Lands cattle allotment fencing. Baseline and on-going studies and data collection have occurred since 2004. These have included small mammal live trapping; chiropteran surveys with the use of Anabat; migratory, breeding, and winter avian surveys; amphibian and reptile surveys; deployment of game cameras; animal track and sign identification and movement patterns; vegetation and plant surveys; and a wetland delineation.

  • 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.

Read Full License Page 1/14 Abstract The Red-crowned roofed turtle (Batagur kachuga) and Three-striped roofed turtle (B. dhongoka) are ‘critically endangered’ turtles in the Geoemydidae family. Herein, we generated the novel mitochondrial genome sequence of B. kachuga (16,155) and B. dhongoka (15,620) and compared it with other turtles species. Batagur mitogenome has 22 transfer RNAs (tRNAs), 13 protein-coding genes (PCGs), two ribosomal RNAs (rRNAs), and one control region (CR). The genome composition was biased toward A + T, with positive AT-skew and negative GC-skew. In the examined species, all 13 PCGs were started by ATG codons, except COI gene, which was initiated by GTG. The majority of mito-genes were encoded on the heavy strand, except eight tRNAs and the ND6 region. We observed a typical cloverleaf structure for all tRNA, excluding tRNASer (AGN), where the base pairs of the dihydrouridine (DHU) arm were abridged. Bayesian Inference (BI) based phylogenetic analysis was constructed among 39 species from six Testudines families, exhibited a close genetic relationship between Batagur and Pangshura with a high supporting value (PP ~ 0.99).

  • Aspects of the Life History of the Texas Map Turtle (Graptemys Versa)
    Am. Midl. Nat. 153:378–388 Aspects of the Life History of the Texas Map Turtle (Graptemys versa) PETER V. LINDEMAN1 Department of Biology and Health Services, 150 Cooper Hall, Edinboro University of Pennsylvania, Edinboro 16444 ABSTRACT.—The Texas map turtle (Graptemys versa) is endemic to the Colorado River drainage in southcentral Texas. A study of its life history was undertaken using data collected in 1998–2000 from a population in the South Llano River, southernmost tributary of the Colorado drainage, and data from museum specimens that had been collected from the South Llano River in 1949. Compared to congeners, G. versa is a small-bodied species. Its small body size is, predictably, linked to relatively small clutch size, small egg size, rapid growth toward asymptotic size and early maturation. As many as four clutches may be laid during an active season, although the effects of follicular atresia on clutch frequency are not known. Both clutch size and egg width were positively correlated with female body size, with the former relationship having a log-log slope significantly less than the expected value of 3, probably due to the latter relationship. Analyses were consistent with the hypothesis of anatomical constraint on egg size, with at least smaller females laying eggs that are of less than optimal size. No differences were found in body size or clutch size between 1949 and 1998–2000 despite a large- scale change in diet associated with invasion of the river by Asian clams (Corbicula sp.). However, body size is substantially reduced in the South Llano River compared to other sections of the Colorado drainage, a finding mimicked by at least one other turtle species in the drainage, Pseudemys texana.

Ernst 2 1 4430 Richmond Park Drive East, Jacksonville, FL, 32224, USA and Department of Biological Sciences, Marshall University, Huntington, WV, USA; [email protected] — 2 Division of Amphibians and Reptiles, mrc 162, Smithsonian Institution, P.O. Box 37012, Washington, D.C. 200137012, USA; [email protected] Accepted 19.ix.2016. Published online at www.senckenberg.de / vertebrate-zoology on 27.vi.2016. Abstract Family Emydidae is a large and diverse group of turtles comprised of 50 – 60 extant species. After a long history of taxonomic revision, the family is presently recognized as a monophyletic group defined by unique skeletal and molecular character states. Emydids are believed to have originated in the Eocene, 42 – 56 million years ago. They are mostly native to North America, but one genus, Trachemys, occurs in South America and a second, Emys, ranges over parts of Europe, western Asia, and northern Africa. Some of the species are threatened and their future survival depends in part on understanding their systematic relationships and habitat requirements. The present treatise provides a synthesis and update of studies which define diversity and classification of the Emydidae. A review of family nomenclature indicates that RAFINESQUE, 1815 should be credited for the family name Emydidae. Early taxonomic studies of these turtles were based primarily on morphological data, including some fossil material. More recent work has relied heavily on phylogenetic analyses using molecular data, mostly DNA. The bulk of current evidence supports two major lineages: the subfamily Emydinae which has mostly semi-terrestrial forms ( genera Actinemys, Clemmys, Emydoidea, Emys, Glyptemys, Terrapene) and the more aquatic subfamily Deirochelyinae ( genera Chrysemys, Deirochelys, Graptemys, Malaclemys, Pseudemys, Trachemys).

Blood samples were taken from two male and two female turtles. Standard T-lymphocyte cell culture at 26°C for 96 h was ap- plied. The mitotic chromosomes were harvested by colchicine-hypotonic-fixation-air drying tech- nique. Conventional staining and GTG-banding techniques were applied to stain the chromosomes with 20% Giemsa’s solution. Results showed that the number of diploid chromosomes was 2n=50, while the fundamental number (NF) was 40 in both males and females. The types of macrochromo- somes were 4 metacentric, 8 submetacentric, 6 acrocentric, 4 telocentric chromosomes, and 28 mi- crochromosomes. The GTG-banding technique showed that each chromosome pairs could be clearly differentiated and the numbers of bands in the M. macrocephala was 99. There is no observation of strangely size chromosomes related to sex. The karyotype formula is as follows: m sm a m sm a t 2n (50)=L2 +L2 +M2+S2 +S6 +S4+S4+28 microchromosomes Key words Malayan snail-eating turtle, Malayemys macrocephala, Karyotype, Idiogram.
