Abstract. Ningrum IK, Santosa Y, Setiawan Y. 2023. Variation of weekly home range characteristics of Sumatran elephants (Elephas maximus sumatranus) in Bentang Seblat, Bengkulu Province, Indonesia. Biodiversitas 24: 5854-5862. Bentang Seblat is one of the areas of conflict between Sumatran elephants and humans arising from space use problems because Sumatran elephants have specific preferences for habitat characteristics. This study aims to identify the characteristics of the weekly home range and analyze the relationship of weekly home range with habitat characteristics of Sumatran elephants in Bentang Seblat. GPS collar data from November 2020 until August 2022 were obtained from the Natural Resources Conservation Agency of Bengkulu-Lampung Province and habitat characteristics were obtained from Landsat 8 imagery. The data obtained were analyzed using chi-square test and Multiple Regression Analysis (MRA) with five variables: land cover, slope, distance from water sources, roads, and settlements. The results showed that the weekly home range was between 2.67 ha-239.98 ha, averaging 46.1 ha. The highest percentage of each habitat characteristic includes secondary forest (55.38%), flat slopes (59.01%), distances of 0-450 m from water sources (35.11%), distances of 0-400 m from roads (70.81%), and distances of 6-8 km from settlements (50.37%). The weekly home range is closely related to all habitat characteristics, with the highest level of relationship significance being the distance from water sources and the distance from the settlement.

Abstract. Malik HN, Rahman DA, Setiawan Y, Huda R. 2024. Mapping habitat suitability and connectivity for the Sunda clouded leopard (Neofelis diardi) in Batutegi Protected Forest, Lampung, Indonesia. Biodiversitas 25: 2249-2256. One of the rarest and least understood species of carnivore, the Sunda clouded leopard (Neofelis diardi Cuvier, 1823), is facing considerable threats from continued habitat loss and fragmentation. The Batutegi Protected Forest, Lampung, Indonesia, which was recently identified as an existing but isolated habitat of this vulnerable felid, is also experiencing fragmentation and encroachment. These combined threats have led to a reduction in the availability of suitable habitats for this isolated population and created barriers restricting its movement between forested areas. Understanding the factors that influence habitat selection and developing ecological corridors to improve its connectivity is critical to the conservation of the Sunda clouded leopard in Batutegi Protected Forest. We examined camera trap data and used maximum entropy modeling to construct a habitat suitability map, which was used to develop the resistance surface. We then performed habitat connectivity analysis using least-cost modeling. Our results indicated that there was a moderate potential in some areas of the study region to support the occurrence of Sunda clouded leopard, whose presence was mainly driven by the presence of forested landscapes and higher elevations. The predicted connectivity network revealed that the most suitable corridor could facilitate the movement of Sunda clouded leopards between forested areas by avoiding the monoculture plantations and mainly crossing through a matrix of forested patches and mixed plantation areas. This study contributes important insights to assisting in the prioritization of habitat conservation for the protection of Sunda clouded leopard and overall forest biodiversity due to its capacity as an umbrella species.
