Long-Term Population Survey of the Sulawesi Black Macaques (Macaca nigra) at Tangkoko Nature Reserve, North Sulawesi, Indonesia

Indonesia, like many other developing countries, is turning to ecotourism in an attempt to integrate the goals of development and nature conservation. Although ecotourism may be a valuable tool for preservation of biodiversity, it can have long-term negative effects on reserves, wildlife and local communities if improperly managed. In this study the authors evaluated ecotourism in the Tangkoko DuaSudara Nature Reserve, North Sulawesi, by examining trends in visitor numbers, the tourist experience, the distribution of tourist revenues, and tourist impact on the Sulawesi black macaque Macaca nigra and spectral tarsier Tarsier spectrum. The data collected showed that, although tourism is expanding rapidly, local benefits are not being fully realized, the reserve does not generate enough money to implement management, and primate behaviour is being affected. There is urgent need for a change in legal status of the reserve if ecotourism is to be managed. National park status would accommodate ecotourism planning and development, provide for greater participation by the local community, and allow for increased revenues for management.

Crested macaque (Macaca nigra), one of the seven endemic primates in Sulawesi is the most endangered macaque species that has been categorized as critically endangered by International Union for Conservation of Nature (IUCN). However, almost nothing is known about the reproductive biology in associated with the behavioral during pregnancy. The data is important to support a management and breeding programs such as pregnancy diagnostic and conservation program in this species. The research aimed was to study the behavior of the crested macaques during pregnancy. Observations were performed on the 10 adult females of the group of Rambo 1 (R1) which has been habituated at Tangkoko-Batuangus Nature Reserve, North Sulawesi. Behavioral data were collected using focal animal sampling and recorded using instantanaeous sampling on females during menstrual cycling, pregnancy, and after parturition (lactation). During five months observations, a total of 393.63 observation hours were recorded. The results showed that daily activities of the M. nigra during menstrual cycling were dominated by feeding (26.60%), foraging (15.95%), and locomotion (16.16%). Daily activities during pregnancy was dominated by feeding (27.03%), foraging (16.37%), and resting (13.45%), whereas after parturition (lactation) period is dominated by resting (26.12%), foraging (19.51%), and feeding (14.98%). The resting was the most activity in the end of pregnancy and few day after parturition. The diets were collected successfully composed of the fruits (34 species), arthropods (3 species, 2 families, 4 orders), fungi (4 genus), and plants (5 species). Climate was influenced on the composition of the diet, especially on fruit and arthropods. In conclusion, the activity budgets were different during menstrual cycling, pregnancy, and lactation, especially feeding, foraging, locomotion, and resting.

The Future

THE USE OF SHOOT STRATIFICATION OF YAKI (Macaca nigra) at DUASUDARA TANGKOKO NATURE RESERVE NORTH SULAWESI. The Sulawesi black macaques (Macaca nigra) habitat at the Tangkoko and Duasudara Nature Reserves in North Sulawesi Indonesia has been the focus of periodic assessment since the late 1970s. Ongoing habitat loss and hunting remain the primary threats to the macaques in these adjacent reserves. Surveyed on habitat condition (including vegetation stratum utilization profile) and the interaction between yaki and local people around the nature reserve were conducted over a four-month period. Methods used diagram for habitat profile and interviewed for interaction between yaki and local people. They used stratum A and B frequently (65.21%) in the forest and prefer big trees, with many branch to sleep. The spread of population depends on the availability of resources in the forest. Without increased efforts to reduce hunting pressure and habitat loss, the future of this population is in question. Keywords: The use of shoot stratification, macaca nigra, nature reserve

The issues of habitat loss and hunting are of paramount importance to wildlife conservation in Asia. In Sulawesi, Indonesia, these problems are having a serious impact on the vertebrate fauna. Using line-transect methods, the densities of 11 species of large birds and mammals were compared between 1979 and 1994 in the Tangkoko-DuaSudara Nature Reserve in North Sulawesi. During those 15 years, populations ofanoa Bubalus depressicornis, bear cuscus Phalanger ursinus, crested black macaque Macaca nigra, maleo Macrocephalon maleo and red junglefowl Gallus gallus declined by 50–95 per cent while populations of Sulawesi pig Sus celebensis, Tabon scrubfowl Megapodius cumingii, Sulawesi tarictic hornbill Penelopides exarhatus and red-knobbed hornbill Aceros cassidix increased by 5–100 per cent. We considered hypotheses for these changes: habitat loss outside the reserve, habitat degradation inside the reserve, and hunting. Only hunting adequately explained the pattern of changing densities observed. Unless protection from hunting is enforced for these species, we may soon witness the demise of these unique animals in North Sulawesi and possibly throughout the island.

Length Of Gestation

A research about gestational length of Sulawesi crested black macaque (Macaca nigra) has conducted to determine the length between conception and birth. Five adult females of Rambo II Group at Tangkoko-Batuangus Nature Reserve, North Sulawesi, were used as samples. Data collection used focal animal sampling to observe the sex swelling cycle and the time when they gave birth. The length of gestation was determined by counting the time duration between middle fully swollen until giving birth. Data was analyzed descriptively to count the mean and standard deviation. Result showed that the gestational length of Sulawesi crested black macaque was 183.6 ± 11.6 days. From this result can be concluded that the gestational length of this species is longer than other Macaca species.

The Impact

The long-term population dynamics of the red deer (Cervus elaphus L.) and European roe deer (Capreolus capreolus L.) at the mountain and forest zone of Crimea during 1980-2017 is presented. Fluctuations in numbers of both species are cyclical and partly synchronous. Period of oscillations in the population of red deer is about 25 years, the average duration of the oscillation period of number of roe deer is 12.3 years. During the fluctuations in the number the increasing and fall in population number of the red deer had been as 26-47 %, and roe deer – as 22-34 %. Basing on the dada obtained we have assumed that together with large-scale cycles of fluctuations in population number of both red deer and roe deer the short cycles of fluctuations in the number of these species with period from 3.5 to 7.5 years take place. Significant differences of the parameters of cyclical fluctuations in the number of roe deer at some sites of the Mountainous Crimea: breaches of synchronicity, as well as significant differences in the duration of cycles are revealed. The greatest deviations from the average values of parameters of long-term dynamics of the number of roe deer in Crimea are noted for groups of this species at two protected areas. At the Crimean Nature Reserve the cycle time of fluctuations of the numbers of roe deer was 18 years. At the Karadag Nature Reserve since 1976 we can see an exponential growth in number of roe deer that is continued up to the present time. By 2016 the number of roe deer reached 750 individuals at a density of 437 animals per 1 thousand ha. Peculiarity of dynamics of number of roe deer at some sites proves the existence in the mountain forest of Crimea several relatively isolated groups of deer. We assumed that "island" location of the Crimean populations of red deer and European roe deer, their relatively little number and influence of permanent extreme factors of both natural and anthropogenic origination have contributed to a mechanism of survival of these populations. The elements of such a mechanism include the following features of long-term dynamics of the population: the reduction in the period of cyclic population fluctuations, while maintaining their amplitude and the appearance of additional small cycles, providing more flexible response of the population to the impact of both negative and positive environmental factors. From the totality of the weather conditions for the Crimean population of roe deer the recurring periods of increases and downs in the annual precipitation amount may have relevance. There was a trend of increase in the roe deer population during periods of increasing annual precipitation.
