Suitable Habitat Modeling of Prehistoric Antelope-like Bovid <em>Duboisia Santeng</em> in Java Island in The Early Pleistocene

Abstract

The migration routes have facilitated the distribution of mammals from south east Asian mainland to the Sundaland including Java island in the early Pleistocene. One of species that has migrated through that route is antelope-like bovid Duboisia santeng. In the present study, the potential distribution areas and the suitable habitats of D. santeng have been projected and modeled. The modeled habitat was a forest river basin sizing 302.91 Ha in the central of Java island. The model has classified and reconstructed the habitat suitability ranged from low to high back to Pleistocene. The surrounding areas of forest were mostly classified as medium and low related to the limited tree covers. Most suitable habitats were identified in the middle of forest river basin where the tree covers were presented

“…The second location was in the forest on the east side of the forest. Habitat modeling was following method by Wibowo (2020) with some modifications. Previous study was on forest dwelling species while hippos are known preferring aquatic habitat as well.…”

“…In their habitat, hippos are having micro aquatic habitats including lakes and rivers (Dietz et al 2000, Kanga et al 2011. According to Wibowo (2020), the habitat modeling was started from classification of vegetation covers from the orthophoto. The photo then classified into vegetation covers included trees, shrubs, and grass.…”
