Conservation managers often monitor umbrella species as indicators of broader biodiversity patterns, but this assumption is seldom evaluated due to lack survey data and objective criteria. We the performance eight candidate in representing patterns mammal Sumatra, Indonesia, using a comprehensive camera trap dataset from island's largest remaining tropical rainforest. employed an occupancy modeling framework quantify association between species-level four community-level parameters while...
Abstract Conservation organisations and governments often use charismatic megafauna as surrogates to represent broader biodiversity. While these species are primarily selected “flagships” for marketing campaigns, it is important evaluate their surrogacy potential, i.e. the extent which protection benefits other biodiversity elements. Four used in megadiverse island of Sumatra: Sumatran tiger Panthera tigris sumatrae , elephant Elephas maximus sumatranus orangutan Pongo abelii rhinoceros...
Abstract Encounter rates of carnivores with prey are dependent on spatial and temporal overlap, often highest their preferred prey. The Critically Endangered Sumatran tiger Panthera tigris sumatrae is populations, but little known about its preferences. We collected camera-trap data for 7 years (2010–2016) in Bukit Barisan Selatan National Park, Sumatra, to investigate overlap tigers potential species. also developed a novel method predict predator–prey encounter preferences from data....
Rapid and widespread biodiversity losses around the world make it important to survey monitor endangered species, especially in hotspots. Bukit Barisan Selatan National Park (BBSNP) is one of largest conserved areas on island Sumatra, for conservation many threatened species. Sumatran tigers (Panthera tigris sumatrae) are critically serve as an umbrella species conservation, but may also affect activity distribution other carnivores. We deployed camera traps 8 years area with little human...
Abstract Forest fires can cause direct mortality to wildlife, and the associated habitat damage reduce carrying capacity population densities. However, little is known about long‐term responses of animals fire in wet tropics. From 2000‐2015, we examined siamang ranging patterns damaged by assess effects on these arboreal frugivores. We mapped home ranges (HR) seven groups inhabiting contiguous HR 3‐5, 10‐12, 17–18 years post‐fire. predicted that if connectivity or quality improved over time...
Abstract. Adyn MF, Sibarani MC, Utoyo L, Surya RA, Sedayu A. 2022. Role of siamang (Symphalangus syndactylus) as seed dispersal agent in a Sumatran lowland tropical forest. Biodiversitas 23: 2101-2110. Seed is mutualistic interaction between angiosperms and agents. One the important dispersers for forests, including Bukit Barisan Selatan National Park (BBSNP), syndactylus Raffles, 1821). This study aimed to determine pattern, composition dispersed seeds, fate by siamangs at Way Canguk...
Between 2011 and 2016, approximately 50% of siamangs in the Way Canguk Research Area disappeared, including members 7 12 habituated groups. Demographic data from 1998 to 2015 confirm that population decline groups reflects a larger trend local population. There was no evidence hunting primates area, ecological do not suggest substantial changes food availability or predation pressure during this period. From 2014, we monitored only intermittently, most deaths disappearances were observed....
Abstract Surveys targeting flagship species frequently record the presence of other species, providing valuable bycatch data to fill knowledge gaps on ecology overlooked species. Using records from camera-trap surveys for tiger Panthera tigris , we model occupancy sun bear Helarctos malayanus predict its temporal change in during 2015–2019 and determine activity patterns Bukit Barisan Selatan National Park, part a UNESCO World Heritage Site Sumatra, Indonesia. We performed single-season...
Abstract In Southeast Asian dipterocarp forests, a general flowering (GF) occurs at the multiannual interval. At this phenomenon, least 40% of trees in stands flower synchrony, dominated by Dipterocarpaceae family that hypothesized to be caused changes climate factors, especially ENSO. This study aimed determine pattern Bukit Barisan Selatan National Park (BBSNP) and model for predicting patterns associated with climatic factors 2021-2050. Flowers fruits were observed every month from...
Abstract. Fitriansyah RA, Setiawan A, Rustiati EL, Utoyo L, Sibarani MC. 2022. Spatial distribution and temporal patterns of food tree availability hornbills (Bucerotidae) at Way Canguk Research Station, Bukit Barisan Selatan National Park, Indonesia. Biodiversitas 23: 1990-1997. The presence in an area is associated with availability. As more sources become available, the hornbill population may increase. purpose this research was to determine spatial trees long-term fruiting pattern...
Birds have an important role in controlling natural ecosystems. The presence of hunting traces every year indicates at the Way Canguk Research Station. If this happens continuously, it can cause a decrease diversity and population chirping birds. Therefore, research needs to be carried out determine diversity, evenness, richness, relative density, as well environmental factors that affect bird community, intensity SPWC. was conducted Station, Bukit Barisan Selatan National Park, using point...
