HABITAT SUITABILITY SPATIAL MODEL OF NEAR THREATENED SUNDA TEAL ANAS GIBBERIFRONS (MULLER, 1842) (ANSERIFORMES: ANATIDAE) IN MUARA ANGKE WETLANDS, JAKARTA, INDONESIA

Wetland ecosystems are important habitats for many waterbird species, including the IUCN nearthreatened Sunda Teal Anas gibberifrons, a species that inhabit wetlands in Indonesia. Muara Angke is one of few remaining wetlands located in Jakarta and has potential as an important habitat for Sunda Teal. This study aims to assess and model suitable habitat for near-threatened Sunda Teal in remaining wetlands in Muara Angke in Jakarta, Indonesia. The study areas include an ecotourism park, the western and eastern parts of the Angke protected forest, and the wildlife reserve. Remote sensing data and geographic information system (GIS) analysis were employed to assess Sunda Teal’s habitat suitability. Some environmental variables negatively influencing habitat suitability for the species include the presence of fishponds and settlements, and represent anthropogenic disturbance. In contrast, variables that may positively influence the species include the occurrence of gastropod and crustacea, both groups being known as food resources, and mangrove cover. The highly and moderately suitable habitats were estimated to form 32.36% and 23.48% of the total wetlands, respectively. In contrast, 12.17% was considered unsuitable for Sunda Teal. The ecotourism park had the most unsuitable habitats. In contrast to the ecotourism park, the protected forest, followed by the wildlife reserve, had more moderately and highly suitable habitats

MODELING SHIFTING GEOGRAPHICAL DISTRIBUTIONS OF LEAST CONCERN ASIAN BRACKISH FROG FEJERVARYA CANCRIVORA (GRAVENHORST, 1829) (ANURA: DICROGLOSSIDAE) IN WEST JAVA, INDONESIA RELATED TO CMIP 5 RCP 8.5 CLIMATE CHANGE SCENARIO

Amphibians and their geographical distribution are threatened by climate change, including speciesin West Java, Indonesia. It is estimated that 300 amphibian species are threatened, including the familyDicroglossidae. At the same time, information on how climate change impacts amphibian species inIndonesia is very limited. This study aims to assess and model the suitable habitat for the least concernAsian brackish frog, Fejervarya cancrivora (Gravenhorst, 1829), under the CMIP 5 RCP 8.5 futureclimate change scenario by 2070, analyzed using Maximum Entropy (MaxEnt). The models developedwith MaxEnt showed good predictivity, with an AUC value of 0.701. The models that inform theprecipitation of the wettest month, isothermality, and mean diurnal range variables have significantcontributions to make in shaping F. cancrivora geographical distributions. The models confirm that F.cancrivora had shifted its geographical distribution and had gained and lost habitats under a future climatechange scenario by 2070. F. cancrivora will lose 4,428 km2 of its current habitat and will gain 2,673km2 of new habitat. In total, climate change will cause F. cancrivora to lose its habitat by 1,755 km2
