Currently, there are only two extant species of hippos includ- Nasional Biologi (SEMABIO), ing common (Hippopotamus amphibius) and pygmy hippos (Choeropsis Bandung-Indonesia, October 8, 2020 liberiensis). But in prehistoric times, there were several species. (conference.bio.uinsgd.ac.id) During Pleistocene these species were known to migrate to Java Received : November 20, 2020 Island from Asian Continent and the species was Hippopotamus Accepted : May 05, 2021 sivalensis spp. In this regard, this study aimed to model the habitat DOI: 10.15575/biodjati.v6i1.10250 of H. sivalensis spp., ecology, and biodiversity of Hippopotamus sivalensis spp. based on the fossil record. The model was developed 1,2,3Department of Biology, Faculty of Mathematics and Natural Sciences, based on the Principal Component Analysis (PCA) method using the R Universitas Indonesia, Pondok Cina, statistical package. The results showed that there were 7 populations Beji, Depok, West Java 16424, of H. sivalensis spp. that lived at various altitudes with an average Indonesia of 177 m above sea level (95% CI : 123-232 m). According to PCA, there were at least 2 separate populations of H. sivalensis spp. One e-mail: population occupies the forest while another occupies a habitat *
