Snakes of the Siwalik Group (Miocene of Pakistan): Systematics and Relationship to Environmental Change
Palaeontologia Electronica http://palaeo-electronica.org SNAKES OF THE SIWALIK GROUP (MIOCENE OF PAKISTAN): SYSTEMATICS AND RELATIONSHIP TO ENVIRONMENTAL CHANGE Jason J. Head ABSTRACT The lower and middle Siwalik Group of the Potwar Plateau, Pakistan (Miocene, approximately 18 to 3.5 Ma) is a continuous fluvial sequence that preserves a dense fossil record of snakes. The record consists of approximately 1,500 vertebrae derived from surface-collection and screen-washing of bulk matrix. This record represents 12 identifiable taxa and morphotypes, including Python sp., Acrochordus dehmi, Ganso- phis potwarensis gen. et sp. nov., Bungarus sp., Chotaophis padhriensis, gen. et sp. nov., and Sivaophis downsi gen. et sp. nov. The record is dominated by Acrochordus dehmi, a fully-aquatic taxon, but diversity increases among terrestrial and semi-aquatic taxa beginning at approximately 10 Ma, roughly coeval with proxy data indicating the inception of the Asian monsoons and increasing seasonality on the Potwar Plateau. Taxonomic differences between the Siwalik Group and coeval European faunas indi- cate that South Asia was a distinct biogeographic theater from Europe by the middle Miocene. Differences between the Siwalik Group and extant snake faunas indicate sig- nificant environmental changes on the Plateau after the last fossil snake occurrences in the Siwalik section. Jason J.

Observations on Varanus S. Salvator in North Sulawesi
ARTICLES Biawak 1(2): 59-66 © 2007. International Varanid Interest Group Observations on Varanus s. salvator in North Sulawesi HAROLD F. DE LISLE P.O. Box 1975 Twentynine Palms, CA 92277, US [email protected] Abstract: Asian Water Monitors (Varanus s. salvator) are widespread on the main island of Sulawesi, Indonesia, but rather rare in the province of North Sulawesi because of human predation. This study documents observations on the daily behavior of a small coastal population over a two week period. Observations of aquatic behavior led to discussion of the possibility that this population is able to catch live fish in a particular coastal lagoon. Introduction The Asian Water Monitor (Varanus salvator salvator) is perhaps the most wide-spread of all varanids. It is found from Sri Lanka, northern India, Bangladesh, Burma, Vietnam and Hainan (China) through Malaysia east to the Indonesian islands of Sulawesi and Wetar (De Lisle, 1996). Its ability to colonize the remote islands of Malaysia and Indonesia might be due to its adaptability towards freshwater and saltwater (Traeholt, 1994a), and also its large size is an advantage, giving both the energy reserves and power to survive an extended sea voyage and a greater potential to actually achieve a landfall. Backwash from tsunamis could start this process frequently enough. Figures 1A and B. Remnant primary forest on North Sulawesi Biawak 2007 Vol. 1 No. 2 60 Figure 2.

All rights reserved ISSN 1690-7930 FIRST RECORD OF THE SPINY-TAILED IGUANA CTENOSAURA SIMILIS (GRAY, 1831) (SQUAMATA: IGUANIDAE) IN VENEZUELA DIEGO FLORES 1 AND LUIS FELIPE ESQUEDA 2 1 Biology student, Escuela de Ciencias, Universidad de Oriente, Cumaná, Venezuela. E-mail: [email protected] 2 Research associate, Laboratorio de Biogeografía, Facultad de Ciencias Forestales y Ambientales, Universidad de Los Andes, Mérida 5101, Venezuela. E-mail: [email protected] The spiny-tailed iguanas of the genus Ctenosaura Wiegmann, 1828, range from coastal central Mexico to Panama, inhabiting tropical arid and moist lowlands below 500 m, along Atlantic and Pacific coasts. They comprise about 17 species (Queiroz 1987, Buckley and Axtell 1997, Köhler et al. 2000). Most species posses restricted distributions, although some, like Ctenosaura acanthura, C. hemilopha, C. pectinata and C. similis, show a wider distribution. The later has the greatest distribution, being present from the Mexican isthmus of Tehuantepec, to Colombia, including southern Mexico, Nicaragua, Guatemala, El Salvador, Honduras, Belize, Costa Rica, Panama, Providence and San Andres islands (Smith and Taylor 1950, Smith 1972, Henderson 1973, Köhler 1995a,b). The first author spotted a population of Ctenosaura iguanas in eastern Venezuela, specifically in Anzoátegui state, at the borders of municipios Diego Bautista Urbaneja, Sotillo, and Bolívar. A collected specimen, deposited in the herpetological collection of the Laboratory of Biogeography at University of Los Andes in Mérida (museum number ULABG 7315), substantiates the distribution record.

E-mail: [email protected] Abstract The Paris Natural History Museum herpetological collection (MNHN-RA) has seven historical specimens of Brachylo- phus spp. collected late in the 18th and early in the 19th centuries. Brachylophus fasciatus was described in 1800 by Brongniart but its type was subsequently considered as lost and never present in MNHN-RA collections. We found that 220 year old holotype among existing collections, registered without any data, and we show that it was donated to MNHN- RA from Brongniart’s private collection after his death in 1847. It was registered in the catalogue of 1851 but without any data or reference to its type status. According to the coloration (uncommon midbody saddle-like dorsal banding pattern) and morphometric data given in its original description and in the subsequent examination of the type in 1802 by Daudin and in 1805 by Brongniart we found that lost holotype in the collections. -

Volcanoes & Land Iguanas
Volcanoes & Land Iguanas 1/2 Background Galapagos iguanas are thought to of arrived in the Galapagos archipelago by floating on of rafts of vegetation from the South American continent. It is estimated that a split of iguana species into Land and Marine Iguanas occurred around 10.5 million years ago. In Galapagos, 3 species of land Iguanas now exist. The Land Iguanas include: Conolophus subcristatus (found on 6 islands), Conolophus pallidus (found only on Santa Fe Island) and a third species Conolophus rosada (known for its pink colour) is found on Wolf volcano on Isabela Island. Habitat Land Iguanas are found in the drier areas of the island. Being cold- blooded, to keep warm they bask in the sun and on the volcanic rock, escaping the midday sun by finding shade under vegetation and rocks, and sleeping in burrows to conserve their body heat. Land Iguanas feed on vegetation such as fallen fruits and cactus pads and even the spines of prickly pear © David cactus. Phillips © Galapagos Conservation © Cyder Trust Volcanoes & Land Iguanas 2/2 Reproduction Between 6 and 10 years of age, male Land Iguanas become highly aggressive, fighting for the attention of the female Land Iguanas. Mating then takes place at the end of the year and eggs are usually laid between January and March (June on Fernandina!). However, in order to lay these eggs female Land Iguanas have no option but to scale to the summit of volcanoes. © Phil Herbert The Volcanic Importance Every pregnant female will need to find a patch of volcanic ash; these pockets of warm soft soil are perfect for the incubation of their eggs; however these sites are difficult to come by. -

This document has been submitted by Malaysia (Management Authorities of Peninsular Malaysia – Ministry of Energy and Natural Resources and Department of Wildlife and National Park Peninsular Malaysia).* Background 2. For the last 50 years, Malaysia has sustained a trade in the skins of Common Water Monitors (Varanus salvator), listed in Appendix II since 1975. In accordance of Article IV, paragraph 3, exports of the specimens of Appendix-II species must be monitored continuously and suitable measures to be taken to limit such exports in order to maintain such species throughout their range at a level consistent with their role in the ecosystems and well above the level at which they would qualify for Appendix I. 3. The CITES Scientific and Management Authorities of Peninsular Malaysia committed to improve monitoring and management systems for Varanus salvator in Malaysia, which has resulted in the management system published here (Annex). Objectives and overview of the Management System for Varanus salvator 4. The management report provides information on the biological attributes of V. salvator, recent population data findings in Peninsular Malaysia and the monitoring and management systems used to ensure its sustainable trade. 5. The main specific objectives of the management report are: a) To provide a tool to support wildlife management authorities in Malaysia in the application of CITES provisions such as Non-detriment findings (NDFs).
