  • Predicted Distribution of the Masked Palm Civet Paguma Larvata (Mammalia: Carnivora: Viverridae) on Borneo

Eaton, Azlan Mohamed, Hiromitsu Samejima, Jerrold L. Belant, Stephanie Kramer-Schadt and Andreas Wilting Wilting et al. (2016: Table 2) list all co-authors’ affliations. Abstract. The masked palm civet Paguma larvata is a small carnivore within the civet family Viverridae, currently listed as Least Concern on The IUCN Red List of Threatened Species. Across its global range the masked palm civet uses a range of habitats in tropical and subtropical regions, from lowlands to highlands, but its exact ecological requirements and the use of modifed habitat remains unclear. We analysed 49 (Balanced Model) and 72 (Spatial Filtering Model) location records of the masked palm civet from Borneo to predict habitat suitability. The resulting model predicted the interior and high elevation areas of Borneo to be suitable habitat, while the coastal and other low-lying areas, such as the extensive peat swamp forests in Central Kalimantan, were predicted to be unsuitable. Greater survey effort in South, Central and West Kalimantan and in Brunei is necessary to obtain more records to improve current models and understanding. The species is probably widespread in Borneo and its likely stronghold is in the higher-elevation forests which are currently less threatened and for a large part protected.

The abundance and occupancy of dholes in Khao Yai National Park are the highest among found carnivorous mammals. This demonstrates the importance of the home range of dholes. From the scat analysis, eight species of mammals that are prey can be identified. The dholes mainly consume ungulates when considering the most percentage of relative biomass consumed were ungulate species. For the number of prey animals consumed by dholes per year, a dhole consumes 25.94 prey animals per year which consist of 6.51 masked palm civets, 6.44 Asian palm civets, 4.55 muntjac, 3.97 lesser mouse-deer, 2.22 large Indian civets, 1.03 wild boars, 0.66 sambar, and 0.56 porcupines.

L. Allen, M. C. Sibarani, L. Utoyo, M. Krofel Allen, M. L., Sibarani, M. C., Utoyo, L., Krofel, M., 2020. Terrestrial mammal community richness and temporal overlap between tigers and other carnivores in Bukit Barisan Selatan National Park, Sumatra. Animal Biodi- versity and Conservation, 43.1: 97–107, DOI: https://doi.org/10.32800/abc.2020.43.0097 Abstract Terrestrial mammal community richness and temporal overlap between tigers and other carnivores in Bukit Barisan Selatan National Park, Sumatra. Rapid and widespread biodiversity losses around the world make it important to survey and monitor endangered species, especially in biodiversity hotspots. Bukit Barisan Selatan National Park (BBSNP) is one of the largest conserved areas on the island of Sumatra, and is important for the conservation of many threatened species. Sumatran tigers (Panthera tigris sumatrae) are critically endangered and serve as an umbrella species for conservation, but may also affect the activity and distribution of other carnivores. We deployed camera traps for 8 years in an area of Bukit Barisan Selatan National Park (BBSNP) with little human activity to document the local terrestrial mammal community and investigate tiger spatial and temporal overlap with other carnivore species. We detected 39 mammal species including Sumatran tiger and several other threatened mammals. Annual species richness averaged 21.5 (range 19–24) mammals, and re- mained stable over time. The mammal order significantly affected annual detection of species and the number of cameras where a species was detected, while species conservation status did not.

The animal species sampled are Masked palm civet (Pagu- ma lavata), Binturong (Arctictis binturong), Asian palm civet (Paradoxurus hermaphroditus) and Small-toothed palm civet (Arctogalidia trivergata). Blood samples taken from Khao Khiew Zoo, Songkhla Zoo and Dusit Zoo were examined using lymphocyte culture techniques. The results indi- cate that the number of diploid chromosome of Masked palm civet, Binturong, Asian palm civet and Small-toothed palm civet are 44, 42, 42 and 40, respectively. The fundamental number (NF) are 62, 46, and 50 for both male and female Masked palm civet, Binturong, Asian palm civet, while that of Small-toothed palm civet is 56 for female and 55 for male. The type number of autosomes, metacen- tric, submetacentric, acrocentric and telocentric chromosome are 6-10-10-16, 2-4-16-18, 2-4-20-14, and 6-8-10-14, respectively. Chromosome pairs 17, 19, and 20 are satellite chromosomes. The X and Y chromosomes are large submetacentric and small submetacentric for the Masked palm civet, whereas the Binturong and Asian palm civet have large metacentric and small submetacentric.
