Cephalopachus bancanus as one of the tarsier species listed as vulnerable in the IUCN red list has limited and different information about their vocalization. This research was designed to explore the species vocalization in the vicinity of Petaling Village, District of Bangka, Bangka Island, Indonesia. Tarsier vocalization inside temporary enclosures was recorded using a handy recorder and analysed using bioacoustics software Audacity 2.3.3 and Raven Pro 1.6.1. We described seven vocalization types with different functions and spectrogram patterns. One type of vocalization, squeak, is produced only by the infant. Two types of vocalizations (whistle and cheeps) were produced by the infant and adult, and four vocalization types were performed by adults. Those types of vocalizations can be heard within human hearing. Some types of vocalizations have peak frequencies at the ultrasonic level, i.e.: agonistic scream, alarm ...

With sufficient food and other vital prerequisites, animals use and defend smaller areas (Brown & Orians, 1970; Bolen & Robinson, 1995; Heiduck, 2002) and thus, energy expenditure for food acquisition is minimized. Relatively large ranges and long distances travelled may be indicators of less than optimum living conditions. Few previous studies have looked at tarsier survival under different disturbance regimes. Population densities of western tarsiers Tarsius bancanus in Borneo are highest in secondary vegetation (Niemitz, 1979). Spectral tarsiers Tarsius spectrum in northern Sulawesi occur in several kinds of habitats, with population densities varying according to study region, habitat type and altitude (MacKinnon & MacKinnon, 1980). Dian's tarsiers Tarsius dianae are slightly more abundant in secondary than in primary forest, but in heavily disturbed habitat densities are considerably lower (Merker & Mühlenberg, 2000). For other prosimian primate species, findings vary. Ganzhorn (1995, 1999) reported better living conditions for several lemur species on Madagascar after selective logging than before. Population densities of the grey mouse lemur Microcebus murinus were found to be higher in primary than in secondary forest (Ganzhorn & Schmid, 1998). In most cases, varying food availability and predation pressure were thought to be responsible for the differing densities. For tarsiers, no previous

We compiled most recent update records of U. polylepis in Indonesia based from local social media and internet supported with photographs or other evidences. There are 42 total records of U. polylepis in Indonesia. From those reports, there are 13 new records of U. polylepis in Sumatra between 2016 and 2019, four new reports in Kalimantan between 2018-2019, and no recent update information from Java.

Three field visits were carried out to looking at how many number of bird an unique landscape in Ogan Komering Ilir district, South Sumatra province, Indonesia. The area covering is about 2.863 km², mostly dominated by wetlands, ranging from peatland to the mangrove zone and including Padang-Sugihan Wildlife Reserve. A survey to asses bird diversity in Sugihan wetlands has been species in this areas. There are 45 species of birds found in Sugihan wetlands, including two species listed as threatened by IUCN (International Union for Conservation of Nature), nine species protected by Indonesian law, and five species listed as CITES (The Convention on International Trade in Endangered Species of Wild Fauna and Flora) appendix II. Presence of threatened, protected species by Indonesian law and number of listed species under CITES appendix II suggest Sugihan wetlands as important habitat for birds.

These photos are considered as second record after 20 years (1997-2017), and first confirm inland record for Sumatra. Photographic records indicate specimens of C. leucas found in Musi River basin recorded about 75 km inland, and apparently very young juveniles. Further study and monitoring is needed to asses the possibility of the importance of Musi River basin as nursery area of C. leucas.

Samples were obtained from Pagar Alam, South Sumatra. Most commonly found at elevations above 600 m in montane and sub-montane primary habitat. Molecular genetic characterization of sumatran striped rabbit is to know genetic information and genetic identification of N. netscheri. Primers 12S rRNA were used in this study to characterize Sumatran striped rabbit. A 1 band were detected ranged from 900 to 1000 bp. Molecular markers represent reliable tools which may have a great impact in rabbit breeding and genetic improvement of rabbits. Molecular markers on Nesolagus netscheri is expected to tools in the identification of Sumatran striped rabbits from South Sumatra.

This paper describes the first record of a young N. netscheri that was offered for sale (the size is approximately 52–56% of the adult), together with an adult, by a social media group in February 2018. The rabbits were reportedly obtained from the Dempo mountain, South Sumatra. Compared to previous descriptions of N. netscheri, the Dempo mountain specimens have longer ears (47–52 mm vs. 34–50 mm), shorter tails (9–15 mm vs. 17 mm) and shorter hindfeet (60–65 mm vs. 67–87 mm). The threats to N. netscheri are revisited and discussed.

The area covering is about 2.593 km², mostly dominated by wetlands, ranging from peatland to the mangrove zone. The Padang-Sugihan Wildlife Reserve is a Wildlife Sanctuary that borderly or within Air Sugihan wetlands. Before the area was set aside for a wetland reserve in April 1983 the area was being prepared for transmigrant settlers. Among other threatened wildlife, birds and fishes are two taxa that very fragile to human disturbances. Since November 2016, we explore basic biodiversity information of Sugihan wetlands, particularly focus on fish and bird diversity. A total of 33 species of fishes and 39 birds were recorded, suggest the wetlands in this area support important habitat of rich diversity. To collect information on bird diversity, three survey methods were applied (riverine survey, time point counts and incidental search). For collecting data of fishes, we collect specimens from local fishermen, with additional data collected by us using hand netting and fish trap netting. Long-term study was initiate to providing comprehensive biodiversity information to support sustainable development of Sugihan wetlands.

Spatial and temporal variability of surface chlorophyll-a in the Gulf of Tomini, Sulawesi, Indonesia. Biodiversitas 19: 793-801. The Gulf of Tomini (GoT) is mostly influenced by seasonal and interannual events. So, the immensive aim of this study is to explore spatial and temporal variations of chlorophyll-a (chl-a) and oceanographic parameters in the GoT under the influences of monsoonal winds, El Niño Southern Oscillation (ENSO), and Indian Ocean Dipole (IOD). The data were collected from the satellite imaging of chl-a and sea and surface temperature (SST) as well as surface wind from the reanalysis data for a period of January 2003 to December 2015. Monthly variations of the chl-a and SST in the GoT reveal chl-a bloom in the center part to the mouth of the GoT during the southeast monsoon season (boreal summer). The chl-a concentrations were relatively higher (>0.1 mg m-3) and distributed throughout most of the...

Distributional patterns of stingrays in South Sumatran waters are depend on species or (at least) genus level. Stingrays in South Sumatran waters are recorded from of up to more 100 km inland to the coastal zone area. Following IUCN Red List status, 10 species of stingrays are threatened with status Endangered, Vulnerable and Data Deficient; suggest the South Sumatran waters are important habitat for stingrays in Indonesia.

The research was conducted in January-February 2018. The research sites were 4 different habitat types, namely primary forest, secondary forest, riparian area, and bush and plantation. Data collection uses direct observation and capture techniques along the transect line (linear transect counting) along 1000 m in each habitat type using insect nets. The results of the study obtained 55 butterfly species belonging to 5 families (there were 13 species of Papilionidae, 30 species of Nymphalidae, 7 species of Pieridae, 1 species of Riodinidae, and 4 species of Lycaenidae). The highest Shanon diversity index is in primary forest habitat (Manduriang) with H'= 3.5; followed by shrubs and plantations (Pasir Bintang) with H'= 3.45, and riparian areas (Talang Lebong) with H' = 3.23; while the lowest is secondary forest (Mesagih) with H'= 2.94.

On 2 February 2017, N. netscheri was sighted in the forested Gunung Raya Wildlife Reserve, South Sumatra Province, Indonesia. An immediate follow up survey of local coffee farmers and hunters provided new data on the occurrence and ecology of N. netscheri.
