DNA BARCODING: FOUNDATIONS AND APPLICATIONS FOR SOUTHEAST ASIAN FRESHWATER FISHES

Hadi Dahruddin, Renny Kurnia Hadiaty, Nicolas Hubert — Mon, 30 Jan 2017 08:57:25 +0700

Identifying and delineating species are the primary tasks of taxonomy. Owing to the decreasing interest of the nations for taxonomy and the inventory of living beings, funds have been drastically decreasing during the last two decades for taxonomic studies. As a consequence, the worldwide pool of taxonomists has dramatically decreased. DNA barcoding, as an automated tool for species delineation and identification, proved to rejuvenate the field of taxonomy and open new perspectives in ecology and conservation. In the present review, we will discuss how DNA barcoding established as a new paradigm in taxonomy and how DNA barcoding has been recently integrated in taxonomic studies. We will further detail the potential applications for species identifications and discuss how DNA barcoding may positively impact the inventory and conservation of living beings, particularly in biodiversity hotspots. We emphasise the benefit of DNA barcoding for the conservation of Southeast Asian freshwater fishes.

BIOGEOGRAPHY OF INDONESIAN FRESHWATER FISHES: CURRENT PROGRESS

Arief Aditya Hutama — Mon, 30 Jan 2017 08:57:25 +0700

Southeast Asia is one of the most geologically complex tropical regions on Earth, in which the intricate interactions among plate tectonics, volcanism and Pleistocene climatic fluctuations led to complex patterns of species distribution. An increasing number of biogeographic studies of the Indonesian ichthyofauna have already partially uncovered the potential mechanisms at the origin of present day species distribution. These studies are currently scattered in the literature and the present review aims at presenting recent progress. Here, we propose a review of this literature with the aim to provide a broad overview of the current progress in the field of Indonesian freshwater fishes biogeography. First, we will briefly present the geology of the Indo-Australian Archipelago (IAA) and highlight the time frame of the geographical settlement of the Indonesian archipelago. Second, we will present the palaeoecological history of Sundaland during the Pleistocene. Finally, we will present the results of recent biogeographic studies across the three biogeographic provinces (Sundaland, Wallacea, Sahul) and discuss how these results fit with geological and palaeoecological scenarios in Indonesia.

Morphological and genetic study of the masked flying fox, Pteropus personatus; with a new subspecies description from Gag Island

Sigit Wiantoro, Ibnu Maryanto — Mon, 30 Jan 2017 08:57:25 +0700

The study on the specimens of Masked Flying Fox, Pteropus personatus from Gag and Moluccas Islands, Indonesia was conducted by using morphological and genetic analyses. Morphologically, the specimens from Gag are different from the other populations in Moluccas Islands by the smaller size of skull, dental and other external measurements. Based on the measurements of the specimens, the population from Gag Island is identified as P. personatus acityae n. subsp. The phylogenetic reconstruction based on partial cytochrome b sequences also support the differences between P. personatus acityae n. subsp and Pteropus personatus personatus. Thus, recently two subspecies of P. personatus are recognised from its distribution areas.

BIRDS OF HALIMUN-SALAK NATIONAL PARK, WEST JAVA, INDONESIA: ENDEMISM, CONSERVATION AND THREATENED STATUS

Dewi Malia Prawiradilaga — Mon, 30 Jan 2017 08:57:25 +0700

Bird surveys and long-term bird monitoring in Gunung Halimun-Salak National Park were conducted between 1998 and 2009 to obtain comprehensive data on the bird species in the area. Compilation of bird data from this study and other studies have recorded a total of 271 species, which is about 53.4% of all Javan birds (507 species) or 16.9% of all Indonesian birds (1605 species). As an important bird area, Gunung Halimun-Salak National Park is home to 43 Indonesian and Javan endemic species. Among the endemics, 32 species are restricted range species. Gaps in the protection status of the bird species are discussed. The results of this study show that Gunung Halimun-Salak National Park has the highest richness of bird species in the Java-Bali region and the conservation of its endemic and threatened species should be given main priority.

MORPHOMETRIC AND MOLT OF THE CRESCENT-CHESTED BABBLER (STACHYRIS MELANOTHORAX) IN CISARUA FOREST, WEST JAVA

Mon, 30 Jan 2017 08:57:25 +0700

Crescent-chested Babbler is endemic to the island of Java and Bali, Indonesia and protected by the Indonesian Government Regulation No. 7/ 1999. Its population is suspected to be declining due to ongoing habitat destruction and fragmentation. Information on its eco-biology is very poorly known. There is a need to obtain the information in order to conserve this species and its habitat. Morphometric and molt stages were recorded from 23 individuals captured by mist-nets between February and April 2016. There were variations in morphometric measurement in weight, head bill length, wing length and tail length in Cisarua Forest habitat, but no significant difference was found (F2.19 = 0.822, P> 0.05) in body weight among the three different habitats. This habitat has sufficient resource for Crescent-crested Babbler for molt activity during the study.

A REVIEW OF THE GENUS SYPHACIA (NEMATODA: OXYURIDAE) FROM MURINE RODENTS IN SOUTHEAST ASIA TO AUSTRALIA WITH SPECIAL REFERENCES TO INDONESIA

Kartika Dewi, Hideo Hasegawa, Mitsuhiko Asakawa — Mon, 30 Jan 2017 08:57:26 +0700

The pinworms of the genus Syphacia are of special interest because they have coevolutionary relationships with their murine rodent hosts. From Southeast Asia to Australia, 21 species in four subgenera have been recorded, two species of these are endemic to Sulawesi. Their biogeographical distribution and dispersal processes are discussed herein. The species composition of Syphacia seems to be mosaic among the islands, especially in Wallacea. Based on the morphological characteristics of the cephalic ends, the species of the subgenus Syphacia are divided into three lineages with square (S), round (R) and laterallyelongated (LE) cephalic shapes. The LE type is assumed to be primitive and the S and R types are derived from the LE type as shown by a molecular phylogeny based on 28S rDNA previously. This assumption was supported by the fact that the old endemics murines in the regions studied mostly harboured Syphacia with LE type A hypothesis on the formation of the host-parasite relationships between murines and subgenus Syphacia in the areas is presented. A key to Syphacia species recorded is also provided
