We measured males and females to determine whether this species exhibits sexual size dimorphism and whether there was a correlation between feeding ecology and body size. We also examined spatiotemporal and sexual variations in dietary composition and prey diversity index. We used these data to examine whether the foraging pattern of these skinks corresponded to the pattern of a sit-and-wait predator or a widely foraging predator. The average snout-vent length (SVL) was significantly larger in adult males than in adult females. When SVL was taken into account as a covariate, head length and width and mouth width were larger in adult males than in adult females. -

John C Naelga*, Daniel Robert P Tayag, Hazel L Yañez, and Astrid L Sinco. Xavier University – Ateneo De Cagayan, Kinaadman Resource Center. ABSTRACT This study was conducted to provide baseline information on the local urban diversity of squamates in the selected areas of Barangay Kauswagan, Barangay Balulang, and Barangay FS Catanico in Cagayan de Oro City. These urban sites are close to the river and are likely to be inhabited by reptiles. Each site had at least ten (10) points and was sampled no less than five (5) times in the months of September to November 2016 using homemade traps and the Cruising-Transect walk method. One representative per species was preserved. A total of two hundred sixty-seven (267) individuals, grouped into four (4) families and ten (10) species were found in the sampling areas. Six (6) snake species were identified, namely: Boiga cynodon, Naja samarensis, Chrysopelea paradisi, Gonyosoma oxycephalum, Coelegnathus erythrurus eryhtrurus, and Dendrelaphis pictus; while four (4) species were lizards namely: Gekko gecko, Hemidactylus platyurus, Lamprolepis smaragdina philippinica, and Eutropis multifasciata.In Barangay Kauswagan, Hemidactylus platyurus was the most abundant (RA= 52.94%). In Barangay Balulang, the most abundant species was Hemidactylus platyurus (RA= 43.82%). In Barangay FS Catanico, the most abundant was Hemidactylus platyurus (RA= 40.16%). The area with the highest species diversity was Barangay FS Catanico (H= 1.36), followed by Barangay Balulang (H= 1.28), and Barangay Kauswagan (H= 1.08). -
An Observational Study of Nusa Penidas Herpetofauna: a Preliminary Examination of the Islands Biodiversity
http://www.fnpf.org/news/scientific-research An observational study of Nusa Penidas Herpetofauna: A preliminary examination of the islands biodiversity Research completed on behalf of FNPF by Sami Asad, 28/10/2011 Abstract The Friends of the National Parks Foundation (FNPF) have recently been attempting to implement a biodiversity monitoring program through its field center on the island of Nusa Penida. At this moment there is little baseline data concerning the islands fauna and flora due to a lack of previous research. Therefore, an examination of the islands herpetofauna will not only provide records for species presence and biodiversity, but will also provide a preliminary assessment of habitat health and ecosystem viability. As such the purpose of this study is to carry out a brief habitat assessment of the island in relation to specific study areas and then survey said areas for herpetofauna thus providing a database for their presence and distribution, as well as providing a measure of biodiversity and habitat health. 1 http://www.fnpf.org/news/scientific-research Contents 1.

Stomach contents (n = 161) were collected from October 2013 to May 2014 using a nonlethal stomach-flushing technique. A total of 680 food items (624 animal items and 56 plant items) was found in 161 stomachs of skinks, representing 19 unique animal categories. We found that the diet of E. multifasciata is composed mainly of small, sedentary and clumped prey and that this skink specialises on spiders, insect larvae, snails, grasshoppers and crickets (with a combined importance index of 60%). Dietary composition, prey size and total prey volume in E. multifasciata changed between dry and rainy seasons and among regions. The total volume of food items consumed by males was larger than that of females, and the diversity and evenness index of prey categories were larger in males than in females. -

Brown Date Approved: April 16, 2014 ii Abstract A comprehensive understanding of the evolutionary processes responsible for generating biodiversity is best obtained using integrative approaches at multiple scales. In doing so, these investigations can provide complex insights into how fine-scale microevolutionary processes operating at the population level, translate into the large-scale macroevolutionary biodiversity patterns we see in evolutionary radiations. Due to the complex geography, historical climatic fluctuations, and remarkably high concentrations of land vertebrate biodiversity, Southeast Asia is an ideal place to investigate these processes. Lizards of the genus Eutropis represent one of the more recognizable radiations of lizards in Southeast Asia, due to their high abundances, broad geographic distribution, and generalized external morphology. However, their evolutionary history has remained enigmatic due to their highly conserved morphology and a lack of dense population sampling of individuals and species across their range. -
Downland 2019 Trip Report
Thailand Wats and Waterfalls A Greentours Trip Report 23rd November to 7th December 2019 Led by Paul Cardy Daily Accounts and Systematic Lists written by Paul Cardy Days 1 & 2 Saturday 23rd & Sunday 24th November Arrival and Chiang Mai I had spent a couple of days in Chiang Mai before the group arrived on Saturday afternoon. Soon all were assembled at the airport, conveniently not far from the centre of town, and with vehicle loaded, our drivers Kampanat and Joe drove us to our beautiful Lanna style hotel, with small attractive gardens, well situated within the city walls. Time for a rest, or for those who wanted a stroll across the road to the city’s most important and impressive temple, Wat Phra Singh. Meeting again in the evening we enjoyed dinner in the hotel restaurant. The food was excellent with an extensive choice of Thai dishes, other Asian fare, and even European choices. Above the city rise the fine forested slopes of Doi Suthep National Park. Centred on the eponymous temple, the main attraction here for most visitors, the park comprises mixed oak/magnolia forest, dipterocarp forest, waterfalls, and caves. Sunday morning saw us heading up here for the day, and in less than an hour we were in fine tranquil habitat. Unprecedented, my alarm clock did not sound this morning, and I was woken by a phone call from reception at the time we should have been leaving, and I hurriedly got ready in five minutes! I walked out to the waiting group full of shame and apologising profusely, pleading lenience as today was my birthday. -

Blood samples were taken from five male and five female skinks. Skink chromosome preparations were conducted by the squash technique from the bone marrow and testis. The chromosomes were stained by conventional staining and Ag-NOR banding techniques. The results showed that the diploid chromosome number of E. multifasciata was 2n=32, the fundamental number (NF) was 48 in both males and females. The types of chromosomes were present as 6 large metacentric, 2 large submetacentric, 6 small metacentric, 2 small submetacentric, 2 small telocentric macrochromosomes and 14 microchromosomes. There was no irregularly sized chromosome related to sex. We also observed distinctive nucleolar organizer regions (NORs) at the region adjacent to the short arms near the telomere of a pair of the largest metacentric chromosomes. We found that during diakinesis (prophase I) the homologous chromosomes showed synapsis, which can be defined as the 16 bivalents and 16 haploid chromosomes at metaphase II as diploid species. -
Molecular Phylogeny of Common Sun Skink, Eutropis Multifasciata (Squamata: Scincidae), of Northwestern Part of Bangladesh
Bangladesh J. Zool. 47(1): 13-25, 2019 ISSN: 0304-9027 (print) 2408-8455 (online) MOLECULAR PHYLOGENY OF COMMON SUN SKINK, EUTROPIS MULTIFASCIATA (SQUAMATA: SCINCIDAE), OF NORTHWESTERN PART OF BANGLADESH Mosharrof Hossain* and Che Jing State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, Kunming 650223, China Abstract: A study on the phylogenetic relationship of Bangladeshi Skink confirmed species as Eutropis multifasciata by Bayesian inference (BI) (100%) and 98% node support to maximum likelihood (ML) tree topology, respectively. The sequence divergences between Eutropis multifasciata and other congeneric species were significant, ranging from 0.1 to 13.6% for 16S rRNA. Intraspecific genetic divergence within E. multifasciata was estimated 10.3%. E. multifasciata formed a distinct clade with high posterior probability support. This maiden study on Bangladeshi Skink results support that one monophyletic subgroup containing all specimens of E. multifasciata and all recently recognized E. multifasciata populations have evolved from one common ancestor. Key words: Scincidae, Eutropis multifasciata, phylogeny, 16S rRNA gene INTRODUCTION The genus Eutropis representing Asian radiation of Scincid lizards have 31 described species (Mausfeld et al. 2002) and many yet to undescribed species occurring from South Asian countries. The phylogenetic relationships of Asian Eutropis are far from being understood and therefore remain largely unclear and speculative. However, some major works provide quite comprehensive data on the Eutropis taxa recognized. Many more additional species have been described by researchers (Boulenger 1887, Rooij 1915, Smith 1935, Tikader and Sharma 1992, Mahony and Reza 2008). We have collected two specimens of robust form of Eutropis that closely resemble Eutropis (25.636574°N, 88.636322°E).
