  • 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.

  • A Preliminary Review of Monitor Lizards in Zoological Gardens
    Biawak, 10(1), pp. 26-35 © 2016 by International Varanid Interest Group A Preliminary Review of Monitor Lizards in Zoological Gardens T+20$6ZIEGLER1,2 ANNA RAUHAUS1,3 & IRI GILL4 1Cologne Zoo Riehler Str. 173 50735 Köln, DE 2E-mail: [email protected] 3E-mail: [email protected] 4ZSL London Zoo Regents Park London, NW1 4RY, UK E-mail: [email protected] Abstract - To gain an overview of monitor lizards held in zoos, including the species and numbers of individuals kept and the number of keeping institutions, we analyzed collection information from the Zoological Information Management System (ZIMS) database. Our analysis performed in March 2016 revealed that there are 50 species of monitor lizard kept globally in 308 zoos, with 39 of these species kept in a total of 131 European zoos. Eleven globally-kept species were lacking in European zoo holdings, and nine species were found exclusively in European zoos. Of the 79 currently recognized species of monitor lizard, 30 (38 %) are not currently held in zoos. Although ZIMS data are certainly not complete, there is a discernible trend that only a few species are widely kept by the zoo community; whereas most species are poorly represented or not represented at all. As only 22 monitor lizard species are listed in the IUCN’s Red List of Threatened Species, there is not only an obvious need for additional Red List assessments, but also a disconnect between the species most frequently kept in zoos and their conservation status. As space and resources in zoos are limited, VSHFLHVVHOHFWLRQVVKRXOGEHZHOOSODQQHG7KHFXUUHQWQXPEHURIR൶FLDO]RREUHHGLQJSURJUDPVIRU monitor lizards is comparatively low and there are further species, such as small island endemics, that require support through assurance colonies sustained by ex situ conservation breeding programs.

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).

  • Varanus Doreanus) in Australia
    BIAWAK Journal of Varanid Biology and Husbandry Volume 11 Number 1 ISSN: 1936-296X On the Cover: Varanus douarrha The individuals depicted on the cover and inset of this issue represent a recently redescribed species of monitor lizard, Varanus douarrha (Lesson, 1830), which origi- nates from New Ireland, in the Bismark Archipelago of Papua New Guinea. Although originally discovered and described by René Lesson in 1830, the holotype was lost on its way to France when the ship it was traveling on became shipwrecked at the Cape of Good Hope. Since then, without a holotype for comparitive studies, it has been assumed that the monitors on New Ireland repre- sented V. indicus or V. finschi. Recent field investiga- tions by Valter Weijola in New Ireland and the Bismark Archipelago and phylogenetic analyses of recently col- lected specimens have reaffirmed Lesson’s original clas- sification of this animal as a distinct species. The V. douarrha depicted here were photographed by Valter Weijola on 17 July and 9 August 2012 near Fis- soa on the northern coast of New Ireland. Both individu- als were found basking in coconut groves close to the beach. Reference: Weijola, V., F. Kraus, V. Vahtera, C. Lindqvist & S.C. Donnellan. 2017.

PROPONENT Federal Republic of Germany C. SUPPORTING STATEMENT 1. Taxonomy 1.1 Class: Reptilia 1.2 Order: Squamata 1.3 Family: Varanidae 1.4 Genus: Varanus Subgenus: Euprepiosaurus Species: Varanus melinus BÖHME & ZIEGLER, 1997 Subspecies: - 1.5 Scientific synonyms:- 1.6 Common names: English: Quince monitor lizard German: Quittenwaran French: Spanish: Indonesian: 1.7. Code numbers: 2. Biological Parameters 2.1 Distribution In their description of Varanus melinus, BÖHME & ZIEGLER (1997) gave the Sula Islands as well as Obi, Moluccas, Indonesia, as distribution area of the Quince monitor lizard. Later ZIEGLER & BÖHME (1999) reduced the distribution of V. melinus to the Sula Islands, because Obi obviously is only an intermediate trading centre (e. g., ERDELEN, ISKANDAR, in litt.). In the Sula Archipelago V. melinus seems to inhabit the islands of Mangole and Taliabu (SPRACKLAND 1999), ISKANDAR (in litt.) further mentions the island of Sanana. Beside Taliabu (see also LEMM 1998) BAYLESS & ADRAGNA (1999) further give Bowokan and Banggai island groups as distribution area of the Quince monitor lizard. According to ERDELEN (in litt.) beside the Sula Islands sometimes also Halmahera and even Sulawesi are mentioned by Indonesian traders as distribution area of V. melinus, thus indicating that the species is still remarkably little known in Indonesia. This applies to the species itself as well as to its geographic range and its ecology. Of ten consulted exporters who were hardly informed about V.

  • THE KEI ISLANDS MONITOR LIZARD (SQUAMATA: VARANIDAE: Varanus: Euprepiosaurus) AS a DISTINCT MORPHOLOGICAL, TAXONOMIC, and CONSERVATION UNIT
    Russian Journal of Herpetology Vol. 26, No. 5, 2019, pp. 272 – 280 DOI: 10.30906/1026-2296-2019-26-5-272-280 THE KEI ISLANDS MONITOR LIZARD (SQUAMATA: VARANIDAE: Varanus: Euprepiosaurus) AS A DISTINCT MORPHOLOGICAL, TAXONOMIC, AND CONSERVATION UNIT Wolfgang Böhme,1* Hans J. Jacobs,2 Thore Koppetsch,1 and Andreas Schmitz3 Submitted Submitted May 27, 2019. We describe a new species of the Varanus indicus group (subgenus Euprepiosaurus) from the Kei Islands, Indone- sia, which differs from its close relative V. indicus by a light tongue, a conspicuous color pattern composed of dis- tinct yellowish ocelli on a blackish ground color and by some scalation characters. From its more distantly related, but morphologically similar relative V. finschi it differs by its midbody scale count and by some peculiarities of its scale microstructure. The new taxon, endemic to the Kei Islands, is also discussed in the light of conservation problems for many Indonesian island endemics.
