Estesia Mongoliensis (Squamata: Anguimorpha) and the Evolution of Venom Grooves in Lizards
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by American Museum of Natural History Scientific Publications AMERICAN MUSEUM NOVITATES Number 3767, 31 pp. January 25, 2013 New materials of Estesia mongoliensis (Squamata: Anguimorpha) and the evolution of venom grooves in lizards HONG-YU YI1,2 AND MARK A. NORELL1,2 ABSTRACT New specimens of the fossil lizard Estesia mongoliensis are described from the Upper Cre- taceous of Mongolia. Phylogenetic analysis of 86 anguimorph taxa coded with 435 morphologi- cal characters and four genes confirms the placement of Estesia mongoliensis in a monophyletic Monstersauria. Extant monstersaurs, the genus Heloderma, are the only extant lizards bearing venom-transmitting teeth with a deep venom grove in the rostral carina. Compared to the crown group, stem monstersaurs are morphologically more variable in venom-delivery appa- ratus. This study has found that Estesia mongoliensis has two shallow grooves in the rostral and caudal carinae of its dentary teeth, demonstrating a primary venom-delivery apparatus. A sum- mary of venom-delivering tooth specialization in the Anguimorpha is provided, and related morphological characters are optimized on the strict consensus tree resulting from the com- bined morphological and molecular analysis of anguimorph phylogeny. The phylogeny supports a single origination of venom grooves in the Monstersauria, and indicates that grooved teeth are currently the only reliable venom-delivery apparatus to be recognized in fossil lizards. Key Words: Estesia mongoliensis, Monstersauria, venom groove, Anguimorpha INTRODUCTION Estesia mongoliensis is the oldest fossil squamate with dental grooves comparable to venom grooves in extant species. -
The Orang-Utan Crisis
106 Oryx THE ORANG-UTAN CRISIS FOREWORD The Orang-utan or Maias, Pongo pygmaeus, which lives only in the islands of Borneo and Sumatra, is one of the animals in greatest danger of extermination throughout the world. The threat comes from the demand for young captive orangs. These are normally obtained by shooting the mother, so that, remembering also the numbers of baby orangs which must be killed accidentally with their mothers or die in transit later from disease or undernourishment, it is reasonable to estimate that for every orang to reach its final destination in captivity, at least three perish. In articles in Oryx, VI, 2, August, 1962, Major Tom Harrisson, director of the Sarawak Museum, and his wife, Barbara Harrisson, brought the position of the Orang-utan vividly before the Fauna Preservation Society and for long before that the Society had been bringing the parlous state of the Orang-utan to the notice of the authorities in Singapore—for most orang-utans obtained in the wild are taken first to that port. More recently, at a meeting of the Executive Board of IUCN in May, 1963, Dr. Harold Coolidge, Executive Director of the National Academy of Sciences, U.S.A., who had just returned from Singapore, told the writer that at least sixty orangs were then " in the pipeline, from Sumatra and Borneo to America and Europe". He suggested that another enquiry should be made at Singapore and this has resulted as follows:— No orang may legally enter Singapore without an import licence and these licences are not granted without an export licence from the country of origin, but control of import is very difficult because of the vast number of ships entering the port and the fact that an orang may be kept on board, nominally as a sailor's pet, until an opportunity to smuggle it ashore occurs. -

Tom Harrisson's Contribution Through Radiocarbon Dating to the Understanding of the Prehistory of Southeast Asia Received 19 September 1977
Tom Harrisson's Contribution through Radiocarbon Dating to the Understanding of the Prehistory of Southeast Asia Received 19 September 1977 RICHARD SHUTLER, JR. OM HARRISSON was appointed Government Ethnologist and Curator of the Sarawak Museum in Kuching in 1947, a post he held until 1966. Although T he was not new to this area, 1947 must be considered the year he officially began archaeological research in Borneo. Tom carried out the first archaeological excavations in Borneo, and, for some areas of that island, these are still the only ones which have been done. From his excavations, particularly at the Great Niah Cave in Sarawak, a number of radiocarbon dates have been obtained that give some idea of the time depth of the prehistoric occupation of Borneo. Harrisson's most important excavations were at Niah Cave, Sarawak, in western Borneo, beginning in 1954. A good deal ofthe work at Niah, Brunei, and Sabah was carried on jointly with Barbara Harrisson. The oldest radiocarbon date for Niah Cave is 41,500 ± 1000 B.P. (GRO-1338), from a depth of 100 inches. Associated with this date are unifacial choppers of classic Southeast Asian Palaeolithic type. From Pit EE, 10 inches below the 41,500 B.P. date, a Homo sapiens skull was found. This is the earliest Homo sapiens skull known from East Asia. Directly below the skull, a small, unretouched flake was found that is described as a "Mid-Sohan" type (Harrisson 1959a). The radiocarbon dates from Niah Cave provide the longest dated cultural sequence in Southeast Asia, going back to 41,500 B.P. -

Multi-National Conservation of Alligator Lizards
MULTI-NATIONAL CONSERVATION OF ALLIGATOR LIZARDS: APPLIED SOCIOECOLOGICAL LESSONS FROM A FLAGSHIP GROUP by ADAM G. CLAUSE (Under the Direction of John Maerz) ABSTRACT The Anthropocene is defined by unprecedented human influence on the biosphere. Integrative conservation recognizes this inextricable coupling of human and natural systems, and mobilizes multiple epistemologies to seek equitable, enduring solutions to complex socioecological issues. Although a central motivation of global conservation practice is to protect at-risk species, such organisms may be the subject of competing social perspectives that can impede robust interventions. Furthermore, imperiled species are often chronically understudied, which prevents the immediate application of data-driven quantitative modeling approaches in conservation decision making. Instead, real-world management goals are regularly prioritized on the basis of expert opinion. Here, I explore how an organismal natural history perspective, when grounded in a critique of established human judgements, can help resolve socioecological conflicts and contextualize perceived threats related to threatened species conservation and policy development. To achieve this, I leverage a multi-national system anchored by a diverse, enigmatic, and often endangered New World clade: alligator lizards. Using a threat analysis and status assessment, I show that one recent petition to list a California alligator lizard, Elgaria panamintina, under the US Endangered Species Act often contradicts the best available science. -
Changes to CITES Species Listings
NOTICE TO THE WILDLIFE IMPORT/EXPORT COMMUNITY December 21, 2016 Subject: Changes to CITES Species Listings Background: Party countries of the Convention on International Trade in Endangered Species (CITES) meet approximately every two years for a Conference of the Parties. During these meetings, countries review and vote on amendments to the listings of protected species in CITES Appendix I and Appendix II. Such amendments become effective 90 days after the last day of the meeting unless Party countries agree to delay implementation. The most recent Conference of the Parties (CoP 17) was held in Johannesburg, South Africa, September 24 – October 4, 2016. Action: Except as noted below, the amendments to CITES Appendices I and II that were adopted at CoP 17, will be effective on January 2, 2017. Any specimens of these species imported into, or exported from, the United States on or after January 2, 2017 will require CITES documentation as specified under the amended listings. The import, export, or re-export of shipments of these species that are accompanied by CITES documents reflecting a pre-January 2 listing status or that lack CITES documents because no listing was previously in effect must be completed by midnight (local time at the point of import/export) on January 1, 2017. Importers and exporters can find the official revised CITES appendices on the CITES website. Species Added to Appendix I . Abronia anzuetoi (Alligator lizard) . Abronia campbelli (Alligator lizard) . Abronia fimbriata (Alligator lizard) . Abronia frosti (Alligator lizard) . Abronia meledona (Alligator lizard) . Cnemaspis psychedelica (Psychedelic rock gecko) .

Bite victims of varanid lizards often report persistent bleeding exceeding that expected for the mechanical damage of the bite. Research to date has identified the blockage of platelet aggregation as one bleeding-inducing activity, and destructive cleavage of fibrinogen as another. However, the ability of the venoms to prevent clot formation has not been directly investigated. Using a thromboelastograph (TEG5000), clot strength was measured after incubating human fibrinogen with Heloderma and Varanus lizard venoms. Clot strengths were found to be highly variable, with the most potent effects produced by incubation with Varanus venoms from the Odatria and Euprepriosaurus clades. The most fibrinogenolytically active venoms belonged to arboreal species and therefore prey escape potential is likely a strong evolutionary selection pressure. -
Prolonged Poststrike Elevation in Tongue-Flicking Rate with Rapid Onset in Gila Monster, <Emphasis Type="Italic">

No. 11, 1994 PROLONGED POSTSTRIKE ELEVATION IN TONGUE- FLICKING RATE WITH RAPID ONSET IN GILA MONSTER, Heloderma suspectum: RELATION TO DIET AND FORAGING AND IMPLICATIONS FOR EVOLUTION OF CHEMOSENSORY SEARCHING WILLIAM E. COOPER, JR. I'* CHRISTOPHER S. DEPERNO I and JOHNNY ARNETT 2 ~Department of Biology Indiana University-Purdue University Fort Wayne Fort Wayne. bldiana 46805 2Department of Herpetology Cincinnati Zoo and Botanical Garden Cincinnati, Ohio 45220 (Received May 6, 1994; accepted June 27, 1994) Abstract--Experimental tests showed that poststrike elevation in tongue-flick- ing rate (PETF) and strike-induced chemosensory searching (SICS) in the gila monster last longer than reported for any other lizard. Based on analysis of numbers of tongue-flicks emitted in 5-rain intervals, significant PETF was detected in all intervals up to and including minutes 41~-5. Using 10-rain intervals, PETF lasted though minutes 46-55. Two of eight individuals con- tinued tongue-flicking throughout the 60 rain after biting prey, whereas all individuals ceased tongue-flicking in a control condition after minute 35. The apparent presence of PETF lasting at least an hour in some individuals sug- gests that there may be important individual differences in duration of PETF. PETF and/or SICS are present in all families of autarchoglossan lizards stud- ied except Cordylidae, the only family lacking lingually mediated prey chem- ical discrimination. However, its duration is known to be greater than 2-rain only in Helodermatidae and Varanidae, the living representatives of Vara- noidea_ That prolonged PETF and S1CS are typical of snakes provides another character supporting a possible a varanoid ancestry for Serpentes. -
