Public Perception on the Existence of Macaca hecki and Macaca tonkeana in Protected Forest and Pangi Binangga Nature Reserve of Central Sulawesi

Wildlife is one of the biological natural resources that can be use it sustainably and sustainably, because wildlife is a natural resource renewable or renewable biological (renewable resources). This study aims to determine public perception of the exixtence of Macaca hecki and Macaca tonkeana in Protected Forest and Pangi Binangga Nature Reserve of Central Sulawesi. This research was carried out along the Palu-Parigi trans road which is in the Protected Forest and Pangi Binangga Nature Reserve, Central Sulawesi Province in April - June 2021. The results showed that presence of endemic Sulawesi macaque (M. hecki and M. tonkeana) along the Palu-Parigi trans road which is in the Protected Forest and Pangi Binangga Nature Reserve area causes various problems such as people experiencing unpleasant events with the presence of macaque, stolen goods, enter into community plantations, and damage various types of agricultural crops (avocado, cloves, cocoa, and several other fruits).

DAMPAK PENGEMBANGAN PROGRAM EKOWISATA BERBASIS SATWA ENDEMIK DI TANGKOKO BITUNG

THE IMPACT OF ENDEMIC ECOTOURISM PROGRAM DEVELOPMENT BASED ON TANGKOKO NATURE RESERVE OF BITUNG. Tangkoko National Reserve is one of the nature reserves located in Bitung regency of North Sulawesi. The reserve covers an area of 8,745 hectares. There is abundant biodiversity such as various types of protected flora and fauna can be found in the reserve. Among them there are endemic wildlifes such as Sulawesi Macaque (Macaca nigra), Tarsiers (Tarsius spectrum), the Sulawesi bear cuscus (Ailurops ursinus), and Hornbill (Rhyticeros cassidix). Here is where the tourists can enjoy the beauty of the reserve or seen firsthand the wealthy of nature in such a protected forest, where the forest has potential as anecotourism spot. Tourism industry has an important role in the development efforts and the development of the region where the tourism spot located.Even in some areas show that tourism industry is able to develop the region as well as create a main income source. The present study was conducted to elaborate the impacts of endemic ecotourism program development basedon the development of Tangkoko nature reserve of Bitung. The study was conducted from November 2016 to January 2017. The ellaboration of the study was focused on the impact of ecotourism developmentonthe existing endemic Sulawesi Black Monkeys and Tarsiers. Survey method was employed to collect and analyze various data and information on endemic fauna of Sulawesi Black Monkeys and Tarsiers. The primary data was obtained through direct interviews with various communities around nature reserve area, and secondary data was obtained from related government sources in Bitung regency.Variables observed were:1) vegetation, 2) the existing wildlife conditions, 3) community income, and 4) the income of the region of Bitung regency.Based on results and discussion, it can be concluded that ecotourism is the best program to be implemented as it could give positive impact towards conservation efforts,increase community's income, and regional income.Keywords: Tangkoko reserve, Ecotourism, Endemic Fauna.

A coalescent framework for comparing alternative models of population structure with genetic data: evolution of Celebes toads

Isolation of populations eventually leads to divergence by genetic drift, but if connectivity varies over time, its impact on diversification may be difficult to discern. Even when the habitat patches of multiple species overlap, differences in their demographic parameters, molecular evolution and stochastic events contribute to differences in the magnitude and distribution of their genetic variation. The Indonesian island of Sulawesi, for example, harbours a suite of endemic species whose intraspecific differentiation or interspecific divergence may have been catalysed by habitat fragmentation. To further test this hypothesis, we have performed phylogenetic and coalescent-based analyses on molecular variation in mitochondrial and nuclear DNA of the Celebes toad ( Bufo celebensis ). Results support a role for habitat fragmentation that led to a population structure in these toads that closely matches distributions of Sulawesi macaque monkeys. Habitat fragmentation, therefore, may also have affected other groups on this island.
