Odonata survey on some of the outer islands of Belitung Regency, Belitung island, Indonesia

2019

Another survey of Odonata on the Indonesian island of Belitung is reported. This sur vey was the second survey conducted in the Belitung area with International Dragonfly Fund support and was focused to Belitung Regency's outer islands. Seventy two species were recorded during the survey. Significant records from the surveyed islands include Amphicnemis kuiperi, Mortonagrion arthuri, Mortonagrion appendiculatum, Teinobasis ruficollis, Platylestes heterostylus, Pornothemis serrata, Pornothemis starrei and Tramea phaeoneura. Almost all the records are new to the small islands surveyed, except for Mendanau Island for which there were already records of four species. A checklist of the odonate fauna of the outer islands is given in an appendix.

Odonata of Ayer Hitam Forest Reserve, Johor, Peninsular Malaysia

2013

Odonata records from Ayer Hitam Forest Reserve and the surrounding area in Johor, Peninsular Malaysia are presented. A total of 44 Odonata species from eight families were collected in the area in October 2012. All of these records are new to Ayer Hitam Forest Reserve. Indothemis carnitica is a new record for Malaysia.

Diversity And Distribution Of Odonata In University Sumatera Utara, Medan, Indonesian

International Journal of Scientific & Technology Research, 2016

A total of nine stations randomly selected study sites around the University Sumatera Utara area conducted during a month (16 January 2016 until 16 February 2016) for identified of Odonata. Odonata are insect which function as bioindicator and conservation of an environment status in the area. The sampled were collected using a sweep net (400 μm mesh, 60 cm x 90 cm) with six times the swing starts at 0900 until 1200 noon hour and identified in the laboratory. Consist of two sub-orders, 4 families, 24 genera, 32 species and 156 individuals identified dragonfly. Orthetrum sabina, Pantala flavescens and Agriocnemis femina are the kinds of dragonflies dominant, while two types of Vestalis/Arethystira amoena and Tholymis aurora is found only in the Station 3. As much as 54% relative abundance of family Coenagrionidae dominated, followed by Libellulidae (35%), Gomphidae (8%) and the smallest recorded from family Calopterygidae (35). The calculation of the value of the index is done, inclu...

The abundance and diversity of Odonata along an altitudinal gradient in East Java, Indonesia

Odonate diversity in East Java was surveyed, and samplings were made during 2 years in ten sites along an altitudinal gradient. The characteristics of odonate assemblages in East Java were analyzed regarding of the number of individuals, the number of species, and Shannon's diversity index. The differences in abundance, species richness, and diversity between study sites were analyzed by an independent t-test. There were 3270 individuals of Odonata belong to 30 species, 7 families and 2 suborders identified from all study sites. The abundance, species richness and diversity of Odonata varied between study sites. The greatest abundance of Odonata was found in Malang Coban Talun (MCT) (148.8 ± 9.5), while the lowest was in South Beach Forest (SBF) (14.4 ± 3.6). The highest species richness and diversity was found in Malang Paddy Field (MPF) (richness =14.4 ± 0.8 and H 0 = 2.4 ± 0.1), while the lowest was found in South Coastal Area (SCA) (richness =2.8 ± 0.1 and H 0 = 0.4 ± 0.1). A significant positive correlation was detected between the elevation and overall odonate abundance (P < 0.05), while there was not significant correlation between that and odonate species richness and diversity.
