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.

A genetic and morphometric study of populations of Zoogoneticus quitzeoensis (Bean, 1898) from the Lerma and Ameca basins and Cuitzeo, Zacapu and Chapala Lakes in Central Mexico was conducted. For the genetic analysis, 7 populations were sampled and 2 monophyletic groups were identifi ed with a genetic difference of DHKY= 3.4% (3-3.8%), one being the populations from the lower Lerma basin, Ameca and Chapala Lake, and the other populations from Zacapu and Cuitzeo Lakes. For the morphometric analysis, 4 populations were sampled and 2 morphotypes identifi ed, 1 from La Luz Spring in the lower Lerma basin and the other from Zacapu and Cuitzeo Lakes drainages. Using these 2 sources of evidence, the population from La Luz is regarded as a new species Zoogoneticus purhepechus sp. nov. _The new species differs from its sister species Zoogoneticus quitzeoensis_ in having a shorter preorbital distance (Prol/SL x = 0.056, SD = 0.01), longer dorsal fi n base length (DFL/SL x = 0.18, SD = 0.03) and 13-14 rays in the dorsal fi n. -
The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N. Reznick1 The evolution of the placenta from a non-placental ancestor causes a species produce large, ‘costly’ (that is, fully provisioned) eggs5,6, gaining shift of maternal investment from pre- to post-fertilization, creating most reproductive benefits by carefully selecting suitable mates based a venue for parent–offspring conflicts during pregnancy1–4. Theory on phenotype or behaviour2. These females, however, run the risk of mat- predicts that the rise of these conflicts should drive a shift from a ing with genetically inferior (for example, closely related or dishonestly reliance on pre-copulatory female mate choice to polyandry in conjunc- signalling) males, because genetically incompatible males are generally tion with post-zygotic mechanisms of sexual selection2. This hypoth- not discernable at the phenotypic level10. Placental females may reduce esis has not yet been empirically tested. Here we apply comparative these risks by producing tiny, inexpensive eggs and creating large mixed- methods to test a key prediction of this hypothesis, which is that the paternity litters by mating with multiple males. They may then rely on evolution of placentation is associated with reduced pre-copulatory the expression of the paternal genomes to induce differential patterns of female mate choice. We exploit a unique quality of the livebearing fish post-zygotic maternal investment among the embryos and, in extreme family Poeciliidae: placentas have repeatedly evolved or been lost, cases, divert resources from genetically defective (incompatible) to viable creating diversity among closely related lineages in the presence or embryos1–4,6,11. -

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. -

TRAFFIC Recommendations on the Proposals to Amend the CITES Appendices at the 16th Meeting of the Conference of the Parties Proposal #/ Species covered by the RECOMMENDATION Proposal Proponent proposal # 38 Aspideretes leithii, Chitra Inclusion of Aspideretes leithii, Dogania With the exception of Palea steindachneri, Pelodiscus maackii and Pelodiscus parviformis, these species chitra,C. vandijki, Dogania subplana, Nilssonia formosa, Palea are threatened to varying degrees by poorly regulated international trade, largely to meet demand in China and subplana, Nilssonia steindachneri, Pelodiscus axenaria, China for food and use in traditional medicines. Some species are heavily traded: Dogania subplana is USA formosa, Palea steindachneri, P. maackii, P. parviformis, and Rafetus traded from Indonesia in large volumes, and to a lesser extent, from Malaysia and the Philippines. Pelodiscus axenaria, P. maackii, swinhoei in Appendix II. Transfer ofChitra Exporters in Indonesia are also known to send large volumes of the look-alike species Amyda P. parviformis, andRafetus chitra and C. vandijki from Appendix II to cartilaginea (currently listed in Appendix II) falsely declared as D. subplana. These species are swinhoei. Appendix I exceptionally difficult for enforcement officers to differentiate from one another, and therefore including all Softshell turtles of them in this proposal on lookalike reasons is warranted. Rafetus swinhoei is one of the rarest chelonians alive. It no longer appears to be found in trade and while inclusion in Appendix II would have been beneficial at an earlier stage, listing now would at least allow for trade controls if specimens are once again found in trade.

(January 2018). 1 1 Native Range and Status in the United States Native Range From Fuller (2018): “This species is confined to a very small area, the Río Ameca basin, on the Pacific Slope of western Mexico (Miller and Fitzsimons 1971).” From Goodeid Working Group (2018): “This species comes from the Pacific Slope and inhabits the Río Ameca and its tributary, the Río Teuchitlán in Jalisco. More habitats in the ichthyological [sic] closely connected Sayula valley have been detected quite recently.” Status in the United States From Fuller (2018): “Reported from Nevada. Records are more than 25 years old and the current status is not known to us. One individual was taken in November 1981 (museum specimen) and another in August 1983 from Rodgers Spring, Nevada (Courtenay and Deacon 1983, Deacon and Williams 1984). Others were seen and not collected (Courtenay, personal communication).” From Goodeid Working Group (2018): “Miller reported, that on 6 May 1982, this species was collected in Roger's Spring, Clark County, Nevada, (pers. comm. to Miller by P.J. Unmack) where it is now extirpated. It had been exposed there with several other exotic species (Deacon [and Williams] 1984).” From FAO (2018): “Status of the introduced species in the wild: Probably not established.” From Froese and Pauly (2018): “Raised commercially in Florida, U.S.A.” Means of Introductions in the United States From Fuller (2018): “Probably an aquarium release.” Remarks From Fuller (2018): “Synonyms and Other Names: butterfly goodeid.” 2 From Goodeid Working Group (2018): “Some hybridisation attempts have been undertaken with the Butterfly Splitfin to solve its relationship. -
Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Dentro de esta gran área geográfi ca se encuentran algunos de los ecosistemas más diversos del planeta (selvas tropicales), así como varios de los principales centros de endemismo en el mundo (bosques nublados). Países como Guatemala, en esta gran área biogeográfi ca, tiene grandes zonas de bosque húmedo tropical y bosque mesófi lo, por esta razón es muy importante para analizar la diversidad en la región. Lamentablemente, la fauna de mariposas de Guatemala es poco conocida y por lo tanto, es necesario llevar a cabo un estudio y análisis de la composición y la diversidad de las mariposas (Lepidoptera: Papilionoidea) en Guatemala. -
