MINISTRY OF AGRICULTURE AND RURAL DEVELOPMENT VIETNAM NATIONAL UNIVERSITY OF FORESTRY STUDENT THESIS EVALUATING THE SPECIES DIVERSITY OF THE FAMILY SCINCIDAE (REPTILIA: SQUAMATA) FROM NAM DONG CONSERVATION AREA, THANH HOA PROVINCE Major: Natural Resources Management Code: D850101 Faculty: Forest Resource and Environmental Management Student: Luong Thi Khanh Linh Student ID: 1553090655 Class: K60 - Natural Resources Management Course: 2015 – 2019 Advance Education Program Developed in collaboration with Colorado State University, USA Supervisor: Dr Luu Quang Vinh Ha Noi, 2019 ACKNOWLEDGEMENTS I am really pleasure to have a chance to send my acknowledgments to people who helped me a lot in the study, without whom this research would have never completed First and foremost, I would like to express my great appreciation to my respected supervisor Dr Luu Quang Vinh from Forest Resources and Environment Management Faculty, Vietnam National University of Forestry (VNUF), who was patient to me and gave me useful guidance and enthusiastic encouragement throughout my research work His great experience and knowledge is heavily embedded in this study I would love to thank Mr Lo Van Oanh, Mr Ha Van Ngoan, Mr Ha Van Nghia, for their assistance and sharing data in the field Therefore, I would like to thank E Sterling (New York) and K Koy (Berkeley) for providing the map I would also like to thank local people in Nam Dong CA for their participating in this survey, hospitality and for providing information Finally, I own my gratefully to my parents for their love, support and encouragements to me throughout all my life Even though difficulties, ado, they always help me as more as possible for my dream This research is supported by the National Foundation for Science and Technology Development (NAFOSTED, Grant No 106.06−2017.18) ABSTRACT This research was conducted to provide the update species in the family Scincidae in Nam Dong Conservation Area, Thanh Hoa Province, Vietnam Six skink species of four genera of the family Scincidae were found during the field surveys in May, June 2017 and in April, May 2018 Two recent research in 2019 were carried out, the first was from 17 May to 20 May and the second fieldtrip was from 24 June to 27 June 2019 Together with two skink species from the previous study, the number of species in the family Scincidae has increased to seven Remarkably, this study described newrecorded skink species for the first time from Nam Dong Conservation Area The species composition of the skink species in Nam Dong is the most similarity to that of Phong Nha-Ke Bang National Park, and the lowest similarity with Van Long Nature Reserve The distribution of skink species in family Scincidae are almost ground of the karst and the species Scincella reevesii and Sphenormophus cryptotis have a narrow distribution habitats The most abundant elevation ranges from (500–600 m a.s.l.), or in the slope areas (700– 800 m a.s.l) and species Sphenomorphus indicus has the most narrow distribution followed elevations to In terms of food ecology, the most abundant prey of family Scincidae in Nam Dong CA was Hymeoptera and the lowest prey was Lepidoptera Finally, habitat loss and degradation and over-havesting for human consumption were main threats to the family Scincidae especially for Scincella reevesii, Sphenormophus cryptotis, Sphenomorphus indicus species and herpetofauna in general in the study site so a specific monitoring and supervision program, strengthening forest protection, and minimize the illegal exploitation, controlling the conversion of forest land into agricultural, popularizarion and education in the direct bad effects of loss biodiversity to local people should be set up TABLE OF CONTENTS ACKNOWLEDGEMENTS ABSTRACT Error!

Hanski 2005; Groom et al 2006) The current extinction rate is assessed to exceed at least 1000 times higher than in the past (Böhm et al 2013; Pimm et al 2014) Deforestation, overexploitation, environmental pollutions, causes, toxicants, and climate change are the main causes of biodiversity loss (Barry et al., 2016) As many as 30% of reptile and amphibian species may bethreatened with extinction (Vié et al., 2009) Southeast Asia is known as one of the 35 hotspots of biodiversity (Myers et al 2000) and the region is also one of the most biotically threatened (Sheldon et al 2015) Especially, the environmental changes have extremely strong impact on the survival of species with narrow distribution ranges, low mobility and specified geographical area like reptiles and amphibians (Gibbons et al.2000; Bickford et al 2010; Böhm et al 2013) Southeast Asia has some of the highest deforestation rates in the world, with estimates of around 14.5% of regional forest cover lost in the last 15 years and an average rate of 1% loss annually (Miettinen et al 2011) Indochina belongs to the Southeast Asia region and is known as a global hotspot of biodiversity and endemism (Sheldon et al 2015) In recent checklist of Laos, it just recorded 16 species of family Scincidae In Cambodia and Thailand, the numbers of these species were found 26 and 56, respectively in In Mynamar, it was dicovered 24 species and the country that detection the highest number of species in the family Scincidae is Malysia with 85 species (Uetz et al 2019) According to World Conservation Monitoring Center 1992, Vietnam has been rated as the 16th most biologically diverse country in the world Between 1943 and 1991, forest cover decreased from 67% to 29% of Vietnam's total area At least 12.6 million of forest, including 8.0 million in Southern Vietnam, have been lost The northern mountains experienced the greatest decline, with forest cover dropping from 95% to 17% in only 48 years In the recent checklist of the Vietnam herpetofauna, Nguyen et al (2009) provided a list of 46 skink species of the family Scincidae Since then 12 new species have been described from Vietnam, increased the total number of species in this family to 58 (Uetz et al 2019) viz Scincella apraefrontalis Nguyen, Nguyen, Böhme & Ziegler, 2010 (Nguyen et al 2010a), Scincella darevskii Nguyen, Ananjeva, Orlov, Rybaltovsky & Böhme, 2010 (Nguyen et al 2010b), Tropidophorus boehmei Nguyen, Nguyen, Schmitz, Orlov & Ziegler, 2010 (Nguyen et al 2010c), Sphenomorphus tonkinensis Nguyen, Schmitz, Nguyen, Orlov, Böhme & Ziegler, 2011 (Nguyen et al 2011), Sphenomorphus sheai Nguyen, Nguyen, Van Devender, Bonkowski & Ziegler, 2013 (Nguyen et al 2013), Sphenomorphus yersini Nguyen, Nguyen, Nguyen, Orlov & Murphy, 2018 (Nguyen et al 2018) and three species newly recorded for the country, namely Scincella monticola (Schmidt, 1925), Sphenomorphus mimicus Taylor, 1962, and Sphenomorphus incognitus (Thompson, 1912) (Nguyen et al 2010d, 2011, 2012) The Nam Dong Conservation Area (CA) was established by the People’s Committee of Thanh Hoa Province in 2014 It is located in Quan Son and Quan Hoa districts (coordinates: 20°18'07''–20°19'38''N and 104°52'08''–104°53'26''E), Thanh Hoa Province with a core zone of 646.95 and a buffer zone of 3,315.53 The CA is situated at elevations between 100 and 900 m a.s.l with the mountain slopes of 10–45%, and inclining from the Northwest to the Southeast The typical habitat of the Nam Dong CA is characterized by the limstone karst forest (Thanh Hoa FPD, 2016) In terms of 10 Sangpradub, N., Boonsoong, B (2006) Identification of freshwater invertebrates of the Mekong River and its tributaries Vientiane, Lao PDR, 276pp Sheldon, F H., H C Lim., and R G Moyle (2015) Return to the Malay Archipelago: the biogeogra-phy of Sundaic rainforest birds Journal of Ornithology 156:91–113 Simmons, J.E (2002) Herpetological collecting and collections management Revised edition Society for the Study of Amphibians and Reptiles Herpetological Circular, 31: 1–153 Smith, M.A (1923) A review of the lizards of the genus Tropidophorus on the Asiatic mainland Proc Zool Soc London 1923: 775-781 Smith, M.A (1935) The fauna of British India, including Ceylon and Burma Reptiles and Amphibia, Vol II Sauria Taylor and Francis, London, 440 pp Taylor, E.H (1935) A taxonomic study of the cosmopolitan lizards of the genus Eumeces with an account of the distribution and relationships of its species The University of Kansas Science Bulletin, 23, 1–643 https://doi.org/10.2307/1436337 Thai, T.V (1970) Classification of forest vegetation in Vietnam The People’s Committe of Thanh Hoa Province (2014) Decision on establish of Nam Dong Endangered Gymnosperm Conservation, Quan Hoa district, Thanh Hoa Province No.:87/QD-UB Thompson,J.C (1912) Herpetological notices, No On reptiles new to the island arcs of Asia Privately published, San Francisco, pp 1-4 Uetz, P., Freed, P & Hošek, J (eds.)
