Distribution Point

Banteng, Bos javanicus, as wild cattle is a vital and importance source of germplasm in Indonesia. Various human activities currently threaten their conservation status. Nonetheless, no long-term monitoring programmes are in place for this species. Using distribution point and statistical analysis based on 46,116 camera trap days from December 2015 to January 2017, we aimed to provide habitat preferences, activity patterns and ecological data for banteng population in Ujung Kulon National Park (UKNP). It is the largest population of banteng in Indonesia and is living in a limited habitat area. According to the best occupancy model, the most suitable areas for this species were the secondary forest located at the center portion of UKNP. The presence of the invasive cluster sugar palm, Arenga obtusifolia, in dry season provides additional alternative food for banteng when its main food is scarcer in the forest. Banteng was cathemeral all year round, with the proportion of cathemeral records and the recording rate did not change with the protection of the level area, moon phase or season. To reduce the probability of encountering predators, banteng avoided the space use of dholes. Selection and avoidance of habitats was stronger than avoidance of the predator activity areas. Habitat competition from domestic cattle which grazed illegally in the national park appears to be a problem to the species since zoonosis appears from domestic cattle to banteng. Therefore, effective law enforcement and an adequate conservation strategy are required to eliminate the impacts of both direct and indirect threats.

AbstractThe Sulawesi civet Macrogalidia musschenbroekii is endemic to the Indonesian island of Sulawesi, where it is the largest mammalian predator. Limited field data means that little is known about the species’ distribution, habitat preferences, conservation status and needs, but it is believed to depend on primary forest. We conducted camera-trap surveys across the forests of North Sulawesi, including in two of its main protected areas: Bogani Nani Wartabone National Park and Tangkoko Nature Reserve. From 148 camera trap stations and 10,371 trap nights, Sulawesi civets were recorded 17 times at 12 stations, and in almost equal numbers in primary forest, secondary forest and farmland, including the first photographic records from both the National Park and Nature Reserve. We also collected data on the Malay civet Viverra tangalunga, an introduced species of Viverridae and potential competitor. Our records (n = 21) revealed that it is established in secondary forest; it only co-occurred twice with the Sulawesi civet. With a lapse of > 20 years since the last field record of the Sulawesi civet, our findings offer new insight into its status and new enthusiasm within the provincial government for its conservation, which has led to an extension of camera-trap research into neighbouring Gorontalo province.

An assessment of tiger beetles in select mountains of Davao region including Mt. Hamiguitan (MHRWS), Marilog District (MD), Davao City (DC), Sta. Cruz Davao del Sur (SCD), and Davao de Oro (DO) is herein presented. Materials were collected between December 2017 and February 2019 through a combination of opportunistic and standard light trapping methods. Twenty-two species belonging to 9 genera were recorded with 64% endemic in the Philippines. Nine (9) species are recorded from MHRWS, 6 from MD, 8 from DC, 5 SCD, and 14 from DO (formerly Compostela Valley Province). Tiger beetles showed consistent habitat preferences particularly riparian species which includes the genera Calomera, Thopeutica, Therates, Prothyma, Cylindera, and Heptodonta. Strictly arboreal species include Tricondyla, Therates, and Neocollyris. Strict epigeic species include but not limited to the genera Calomera, Tricondyla, Thopeutica, Cylindera, Heptodonta, Neocollyris, and Prothyma. Endemic species such as Heptodonta lumawigi (Wiesner, 1980), Thopeutica (Thopeutica) anichtchenkoi (Wiesner 2015), Thopeutica (Thopeutica) milanae (Wiesner, 1992), Thopeutica (Thopeutica) rolandmuelleri Cassola, 2000 and Thopeutica petertaylori (Medina, Cabras, Wiesner, 2019) prefers a more intact forests while others such as Cylindera (Ifasina) discreta elaphroides (Dokhtouroff 1882), Calomera mindanaoensis (Cassola, 2000) and Necollyris sp. could tolerate disturbed secondary forest even agricultural lands. New distribution record for Heptodonta lumawigi (Wiesner, 1980) and Thopeutica (Thopeutica) milanae (Wiesner, 1992) for Marilog District were also recorded. Ecological data and conservation status of tiger beetles are also presented. Conservation actions are deemed necessary in the remaining green spaces in Davao City that hosts tiger beetle fauna should also be conducted.

AbstractOcelots were historically hunted for their skins but habitat loss is now their most serious threat, causing rapid declines in populations throughout their range. Ocelot abundance has been estimated for various locations across the Neotropics, but we still lack this information from some countries, including Ecuador. Knowing whether ocelot abundance is increasing or decreasing is important to assess the conservation status of this species and the conditions of its habitats in the Ecuadorian Amazon and in the region. To determine whether ocelot abundance and its behavior are affected by human-related activities, camera-trap surveys were carried out in two localities of Yasuní National Park (YNP), one that has experienced hunting, oil extraction, and roads (Maxus Road) and one that is largely unaffected by these activities (Lorocachi). During the survey, 35 and 36 individual ocelots were photographed in Maxus Road and Lorocachi, respectively. Population density estimates were similar for both localities, ranging from 0.31 (SE±6) to 0.85 (SE±17) ocelots/km

SummaryWe distributed questionnaires and conducted interviews between July and November 1996 to develop a better understanding of the status and distribution of Bornean Peacock-pheasant Polyplectron schleiermacheri in Central Kalimantan, Indonesia. We found that many people were familiar with the species, that it is apparently widely distributed but rare in lowland forest, and that populations may be declining. We received reports of recent sightings of the pheasant at 23 locations in 9 survey areas. The primary threats to Bornean Peacock-pheasants are habitat loss within logging concessions and hunting. Recommendations for future conservation action include increasing the representation of lowland rainforest in Kalimantan's protected area system, specifically the proposed extension of Bukit Raya National Park, and control of hunting within logging concessions.

Robiansyah I, Dodo, Hamidi A. 2019. Population status of endemic tree kokoleceran (Vatica bantamensis) in Ujung Kulon National Park, Indonesia. Biodiversitas 20: 296-302. Kokoleceran (Vatica bantamensis) is an endemic tree found only in Ujung Kulon National Park (UKNP), Banten, Indonesia, and is classified as Endangered by IUCN Red List. To develop effective conservation measures of threatened plants, current information on population status and distribution of the species is needed. Thus in the present study, a targeted survey of kokoleceran was conducted in UKNP aiming at mapping the distribution of the species, measuring current population size and structure, assessing the habitat preferences, and identifying threats to the species. Using a non-random adaptive cluster sampling, a total of 27 clusters harboring 280 individuals of kokoleceran was located, of which 20 % were in mature stage. All these individuals were only found in Mount Payung and its surrounding areas, and formed an inverse-J-shaped population structure pattern. The species was estimated to have an area of occupancy and extent of occurrence of 8 km2. The invasive langkap palm (Arenga obtusifolia, Arecaceae) was identified as the main threat for kokoleceran. Based on these results, kokoleceran appears to more than justify its conservation status of Critically Endangered B1ab(iii,v) +2ab(iii,v); C2a(ii).

Tentative list of endemic vascular plants of the Zeravshan Mts in Tajikistan: distribution, habitat preferences and conservation status of speciesBased on literature data and own fieldwork in the Zeravshan Mts in Tajikistan (Middle Asia), the taxonomic structure, distribution, habitat preferences as well as conservation status of a group of 86 species of vascular plants of endemic character are presented. The tentative list of exclusive endemic plants for the Zeravshan Mts was compiled. They belong to 25 families. The richest is the genusAstragaluswith 11 species followed byCousinia(8),Allium(5) andScutellaria(3). The study has shown that the eastern subregions of the range are richest in endemics, especially, the Mogien-Daria, Seven Lakes, Pastrud-Daria, Ksztut and Yagnob valleys and Kuli-Kalon Plateau. The endemics studied are stenochoric species with very small number of known locations, mainly between one and two. The mean value of the range of the studied endemics is ca. 1140 km2. The most numerous endemic groups have been recorded at altitudes of around 1,800-2,100 and 2,700-3000 m a. s. l. The habitats harboring the richest group of endemics are rock screes, alpine forests, steppes and semi-savannas, alpine meadows, solid rocks, xerothermophilous shrubs and pastures. Almost half of the endemics have narrow ecological amplitude occurring in only one habitat type. The most important threats to Tajik endemics are intensive grazing and erosion of soils, as well as denudation. Most vulnerable types of vegetation to the human impact are forest and scrub communities. For effective protection of endemics in the Zeravshan Mts, a national park and a net of nature reserves has to be funded.

AbstractThree incidental sightings of the flat-headed cat Pnonailurus planiceps, a little-known species, were made in south-east Sumatra. Sightings were on lowland floodplains in two distinct habitats, primary peat swamp forest and secondary lowland forest, the latter suggesting some tolerance to modified habitats. Sightings were along or near waterways. A dead adult male found in Berbak National Park is the first confirmed record for the park. Morphometrics of this individual were consistent with other published measurements for the species. Museum specimens indicate a wide historic distribution in south-east Sumatra. Recent information confirms the species's presence in protected areas of eastern, southern and western Sumatra, although this is mostly limited to presence/absence data, and the conservation status and habitat requirements of the species in south-east Sumatra are unknown. Regional degradation of riparian habitats and the isolation of protected areas warrant concern for the conservation status of the species.

We provide detailed morphological descriptions of the tadpoles of Malagasy river bank frogs of the subgenera Ochthomantis and Maitsomantis (genus Mantidactylus, family Mantellidae), and data on relative abundance and habitat preferences of Ochthomantis species from Ranomafana National Park in southeastern Madagascar. Our study includes the tadpoles of six described and four undescribed candidate species. Eight of these larvae were previously unknown. Tadpoles were identified by DNA barcoding. Due to the very rudimentary taxonomic knowledge on Ochthomantis, we followed a ‘reverse taxonomy’ approach in which adult classification was to a great part determined on the basis of larval differences. By this procedure we even identified one candidate species whose adults remain still unknown. The majority of tadpoles in Ochthomantis and Maitsomantis have a rather similar body shape and they usually have similar habitat requirements. However, on the basis of the structure of their oral disk we identified three distinct groups: the first includes the femoralis-like tadpoles of Mantidactylus femoralis, M. ambreensis, M. zolitschka, M. argenteus, and of the candidate species named M. sp. 42, M. sp. 43 and M. sp. 47. They all have a reduced oral disk with poorly keratinized jaw sheaths and labial teeth. The mocquardi-like tadpoles of M. mocquardi and M. sp. 64 are placed in the second group and are characterized by a further reduction of oral disk structures, i.e. a complete lack of labial teeth. The third group includes only M. majori and is characterized by the transformation of the upper jaw sheath into three thorn-shaped projections. Based on a preliminary molecular phylogenetic analysis the reduction of keratinized oral structures in M. majori may have occurred convergently to that in M. mocquardi. The ecological data indicate that the tadpoles of the three most abundant species in Ranomafana (M. femoralis, M. majori and M. sp. 47) do not obviously differ in their choice of microhabitat although the differences in their oral structures indicate that they might use different food resources. They all show a preference for the stream areas with slow current and leaf litter substrate.
