    Bioacoustics of Hylarana celebensis (Peters, 1872) (Anura: Ranidae) From Sulawesi [Bioakustik Kodok Hylarana celebensis (Peters, 1872) (Anura: Ranidae) Asal Sulawesi] Hellen Kurniati Zoology Division of Research Center for Biology, Indonesian Institute of Sciences (LIPI), Widyasatwaloka Building-LIPI, Jalan Raya Cibinong Km 46, Cibinong 16911, West Jawa. E-mail: [email protected] Memasukkan: Januari 2015, Diterima: Juni 2015 ABSTRACT Hylarana celebensis (Peters, 1872) is an endemic frog to Sulawesi, the species being a member of family Ranidae. The presence of the frog in its habitat is easily detected from its advertisement call; males usually call in a chorus, they call to each other in a large group. Bioacoustic of calls of a typical individual male of H. celebensis have not been described in detail, although it is very easy to find this species in freshwater swamps, permanent ponds, or slow-flowing waters in the lowland areas. The purpose of the bioacoustic analysis on H. celebensis’s calls that were recorded at Bahodopi area is to build a reference collection to be compared with H. celebensis’s bioacoustics from other regions in Sulawesi. Because of the wide distribution of this frog in Sulawesi; genetic structure of H. celebensis population may also follow the genetic structure of Ingerophrynus celebensispopulation. Calls of H. celebensis have two types of calls, i.e. pure tone and pulse; however, pure tones have three variation, namely pure tone type 1, pure tone type 2 and pure tone type 3; however pulsed call has only one type.

Family COLUBRIDAE Ahaetulla prasina Green Vine Snake This snake was found in Renah Kayu Embun and Napal Licin survey sites at elevation 1400 meters asl and 300 meters asl respectively. Usually it can be seen in degraded habitat including plantation, secondary growth and house compounds, to primary rain forest (Inger and Stuebing, 2005; Kurniati, 2003). It occurs from lowlands up to mountain forests over 1500 meters asl (Kurniati et al., 2001; Kurniati, 2003). It is common species at low elevation (Inger and Stuebing, 2005), but become rare at high elevation such as Renah Kayu Embun survey site. This species is known from South-east Asia, East Indies (Sulawesi and The Lesser Sunda) (Stuebing and Inger, 1999: de Lang and Vogel, 2005). Figure 91. A. prasina (Photograph by H. Kurniati). Amphiesma sp This undescribed snake was found in Muara Labuh survey site at elevation 800 meters asl. It was a nocturnal snake that inhabited strong moving stream bank. The morphology of this snake is similar to A. kerinciense (David and Das, 2003). Possibly, it is a new species, but future study is needed. Figure 92. Amphiesma sp from Muara Labuh (Photograph by H.

    Checklist of Herpetofauna of Tasek Bera Ramsar Site, Pahang

    Journal of Wildlife and Parks, 34 (2019): In press CHECKLIST OF HERPETOFAUNA OF TASEK BERA RAMSAR SITE, PAHANG *Badmanathan Munisamy, Khairul Nizam Kamaruddin, Amri Izaffi Zamahsasri, Hartini Ithnin & Mohd Firdaus Razali Department of Wildlife and National Parks (PERHILITAN), Peninsular Malaysia, KM 10 Jalan Cheras, 56100 Kuala Lumpur, Malaysia. *Corresponding author email: [email protected] ABSTRACT Tasek Bera Ramsar Site (TBRS) in Pahang is the largest freshwater wetland in Peninsular Malaysia and is protected under the Ramsar Convention. There are varieties of ecosystem around this wetland which support the biodiversity of flora and fauna including herpetofauna. A survey of herpetofauna in TBRS was conducted between 7th and 14th May 2014 to review the species richness in this natural wetland area. Throughout the survey, amphibians and reptiles were actively searched along the lake site, interpretive trails and nearby forests. The captured individuals were photographed and morphology measurements were taken for species identification. A total of 34 individuals comprising of 17 species were caught. Out of these 17 species, five species were amphibians from four families (Bufonidae=1; Ranidae = 2; Rhacophoridae= 1; Dicroglossidae=1), five species were snakes from three families (Colubridae=3; Elapidae=1; Viperidae=1 ) and seven species of lizards from three families (Agamidae=1; Gekkonidae=5; Varanidae=1). The ratio number of individual of amphibians to reptiles captured was almost equal (16:18). The highest captured individuals were from Family Gekkonidae. Hylarana erythraea and Gekko monarchus were the most captured species with six individuals each. These survey findings will be helpful in the management and conservation plan of wildlife, specifically herpetofauna of TBRS.

NOR 1 Molecular Ecology Laboratory, Faculty of Resource Science and Technology, Universiti Malaysia Sarawak, Kota Samarahan, Sarawak, Malaysia 2 School of Environment and Natural Resources Science, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, Bangi, Selangor, Malaysia Received: 27.01.2017 Accepted/Published Online: 17.04.2017 Final Version: 28.09.2017 Abstract: Microhabitats play an important role as resources that are partitioned between phylogenetically related or ecologically similar species (i.e., a guild). This hypothesis was tested by first elucidating phylogenetically closed Sarawak frog species via DNA sequencing of the 16S rRNA mitochondrial DNA gene, and later determining their microhabitat guild and partitioning via nonmetric dimensional scale. Mitochondrial 16S gene revealed 5 monophyletic groups consisting of Hylarana erythraea + Amnirana nicobariensis, Chalcorana raniceps, Abavorana luctuosa, Pulchrana signata + P. picturata, and P. baramica + P. glandulosa + P. laterimaculata. On the other hand, microhabitat utilization grouped the frogs into 5 ecological guilds consisting of semiarboreal species at the forest edge (C. raniceps), ground dwellers in an unforested region (H. erythraea), ground dwellers (rock) at the forest edge (P. picturata), ground dwellers on the forest floor and forest edge species (P. signata, P. glandulosa, A. luctuosa, O. hosii), and semiarboreal forest (riverine) species (P. baramica). Thus, the microhabitats used were not influenced by the proposed phylogenetic relationships.

ROBBIE WETERINGS1* & PREEYAPORN WETERINGS1 1 Cat Drop Foundation, Drachten, Netherlands *Corresponding author e-mail: [email protected] Abstract - Various species of ‘house’ gecko are found in and around buildings, where they can be observed feeding opportunistically on the insects attracted to artificial lights. Most of the species are considered strict insectivores. Nevertheless, there have been several recently published observations of ‘house’ geckos feeding on non-insect food. In order to assess how common this behaviour is among geckos worldwide, we offered an online questionnaire to ecologists and herpetologists. Of the 74 observations received, most reported Hemidactylus frenatus, H. platyurus and Gehyra mutilata feeding on rice, bread, fruits, vegetables, dog food or chocolate cream, taken from tables, plates, and garbage bins. This opportunistic feeding behaviour is much more common than previously thought and is perpetrated by species considered to be highly invasive, possibly contributing to their success as invaders.

  • Impact of Habitat Alteration on Amphibian Diversity and Species

    Impact of Habitat Alteration on Amphibian Diversity and Species

    www.nature.com/scientificreports OPEN Impact of habitat alteration on amphibian diversity and species composition in a lowland tropical rainforest in Northeastern Leyte, Philippines Syrus Cesar Pacle Decena*, Carlo Aguirre Avorque, Ian Christopher Pacle Decena, Pol Delbert Asis & Bryan Pacle The impact of anthropogenic habitat alteration on amphibians was investigated, employing an investigative focus on leaf-litter and semi-aquatic species across diferent habitat alteration types. The habitat alteration types which include primary forest, selectively logged primary forest, secondary forest, abandoned farm areas and pasture (this represents a gradient of habitat alteration ranging from least altered to most altered, respectively) also encompass two habitat types: stream and terrestrial. Species assemblage was compared between habitat alteration types and habitat types, where a total 360 leaf-litter and semi-aquatic amphibians were observed (15 species, 6 families). It was found that amphibian abundance was signifcantly higher in both forest and stream habitat, and species richness did not difer with respect to habitat alteration type. It was determined, however, that species richness was highly dependent on habitat type (signifcantly higher in stream habitat). Meanwhile, diversity (Shannon–Wiener) was signifcantly higher in both forest and stream habitat, and species composition difered markedly between habitat alteration types for stream strip plots. Forest habitat exhibited domination by forest specialist species, while altered habitat

    Data Types and the Phylogeny of Neoaves

    Article Data Types and the Phylogeny of Neoaves Edward L. Braun * and Rebecca T. Kimball * Department of Biology, University of Florida, Gainesville, FL 32611, USA * Correspondence: ebraun68@ufl.edu (E.L.B.); rkimball@ufl.edu (R.T.K.) Simple Summary: Some of the earliest studies using molecular data to resolve evolutionary history separated birds into three main groups: Paleognathae (ostriches and allies), Galloanseres (ducks and chickens), and Neoaves (the remaining ~95% of avian species). The early evolution of Neoaves, however, has remained challenging to understand, even as data from whole genomes have become available. We have recently proposed that some of the conflicts among recent studies may be due to the type of genomic data that is analyzed (regions that code for proteins versus regions that do not). However, a rigorous examination of this hypothesis using coding and non-coding data from the same genomic regions sequenced from a relatively large number of species has not yet been conducted. Here we perform such an analysis and show that data type does influence the methods used to infer evolutionary relationships from molecular sequences. We also show that conducting analyses using models of sequence evolution that were chosen to minimize reconstruction errors result in coding and non-coding trees that are much more similar, and we add to the evidence that non-coding data provide better information regarding neoavian relationships. While a few relationships remain problematic, we are approaching a good understanding of the evolutionary history for major avian groups. Abstract: The phylogeny of Neoaves, the largest clade of extant birds, has remained unclear despite intense study.
  • Spatial Partitioning Among Geckos at Lambir Hills National Park

    Spatial Partitioning Among Geckos at Lambir Hills National Park

    One gecko, Two geckos, not few geckos - but many geckos! Spatial partitioning among geckos at Lambir Hills National Park Ruchira Somaweera1, Wayne Hsu2 & Mona Octavia3 1 Department of Zoology, University of Peradeniya, Sri Lanka. 2 Department of Ecology, Evolution, and Environmental Biology, Columbia University, USA. 3 Department of Zoology, University of Malaysia Sarawak, Malaysia. ABSTRACT Four species of sympatric geckos occur in the Lambir Hills National Park headquarters premises. We investigated whether this distribution was facilitated by spatial partitioning among the species. Of the 212 individuals observed in five buildings, there was no significant difference in the distance geckos forage around artificial lights (p = 0.0541). Three of the four species have similar surface preferences. Gekko smithii tends to occur farthest from light sources, and G. monarchus appears restricted to wall surfaces; thus, our results suggest spatial partitioning occurs in multiple ways. INTRODUCTION A mega-hotspot for reptiles, the island of Borneo harbors 289 species of reptiles, of which 29 species are geckos (Gekkonidae) (Das 2006). Over 15 gecko species have been recorded from Lambir Hills National Park (LHNP). Many species have overlapping ranges around the LHNP headquarter premises, attracted to and possibly supported by the abundance of insects around artificial lights at night. Thus, the diverse gecko community provides an opportunity to study inter-specific and intra- specific coexistence and spatial partitioning. The social behavior and spatial partitioning of animals are not only of intrinsic interest, but may also be relevant to our understanding of population dynamics and habitat selection (Stephens & Sutherland 1999). Studies on the social behavior of reptiles have lagged behind those of birds and mammals, reinforcing the traditional view that reptilian social systems are simpler than those of endothermic vertebrates.
