Abstract

ABSTRACT  Mahogany tree besides capturing carbon for its natural growth, it can be hypotezised that the tree has a capability to reduce CO2, heat energy and other pollutant contents that released to the air.  Total carbon captured by the mahagony tree, then can be estimated quantitavely in form of biomass.  The aims of this research were to calculate biomass content on mahagony trees and to estimate the biomass characters on each part of the trees.  The researh was done in UNSRAT area from June to July 2017 by Cencus Method.  The data were analysed by using Allometric Equations developed to calculate biomass content of mahogany tree.  The result showed that from the 313 trees, the total biomass was 304,052.99 kg.  It was characterized by the biomass content on tree trunks was 5 %, stems 73 %, branches 17 %, branchlets 2 %, and on leaves 3 %. These imply that the mahagony tree can be planted to over released pollutant area in order to reduce the CO2, heat energy and other pollutant contents.  Keywords : Mahogany Tree, carbon, biomass, UNSRAT

Abstract

ABSTRACT Macrocephalon maleo S. Muller, 1846, an endemic bird species to Sulawesi and classified as Endangered, is now used as flagship species for conservation purpose. Conversion of its habitat, habitat loss and fragmentation, and degraded habitat quality are several suspected factors that impacted the bird population. Its habitat in Tanjung Binerean at Mataindo Village, South Bolaang Mongondow Regency is now suspected to be declined in form of habitat quality. The aims of this research was to analyze Maleo Bird's habitat based on tree structure and composition. The researh was done in Tanjung Binerean at Mataindo Village, South Bolaang Mongondow Regency in June 2017 by Systematic Strip Method. Data were collected from three transects on 25 plots, and were analysed its relative frequency distribution. The result showed that there were 56 tree species that dominated by Alianthus integrifolia (21,23 %), Cananga odorata (12,16 %), Canarium asperum (8,82 %), and Ficus septica (8,32 %). This imply that the Maleo's habitat is now in disturbed condition with the presence of F. septica.Keywords : Macrocephalon maleo, South Bolaang Mongondow Regency, habitat, flagship species, Ficus septica

Abstract

Abstract Butterflies are a group of insects belonging to the order Lepidoptera, which have two pairs of wings and a scaly body. Butterfly species richness may decrease due to increased deforestation and conversion of forest land which affect the diversity of larval and imago feed plants. The purpose of this research was to analyze the diversity of butterfly species and feed plants for larvae and imago in the protected forests of Mount Tampusu and Mahawu. The method used in this research is the pathway count method. The results showed that there were 5 families of 37 species of butterflies in the two research locations including 26 species in the Mount Tampusu protected forest and 23 species in the Mount Mahawu protected forest. The results of the analysis of the Shannon-Wiener diversity index are H'= 2.74 and the evenness index analysis is: E = 2.74/ln (37) = 0.76. The larval food plants found in the Mount Tampusu Protection Forest were Ficus sp. and feed for larvae found in the Mount Mahawu Protection 2 Forest, namely Glochidion sp., and Alpinia sp.. The imago feed plants in the Mount Tampusu Protection Forest were Crassocephalum crepidioides, Lantana camara, Lindernia crustacean, Mikania cordata and forage plants in the Mount Protection Forest, namely Bidens pilosa, Crassocephalum crepidioides, Hyptis capitate, Impatiens sp., Sida acuta, and Vernonia sp..

Abstract

AbstractFicus is a genus of plants that require external assistance in order to pollinate.Pollination infruit is Ficus highly dependent on various pollinator insects. Thispollinator insect will help the pollination process in Ficus. The purpose of this studywas to determine the pollinator species associated with four species Ficus in theBatuputih Nature Park. This study used a method by tracing the Batuputih Nature Parkarea to collect data on four species Ficus. The results showed that there were 8pollinator species associated with four species Ficus , consisting of 66 pollinators fromthe family Agaonidae, ordo Hymenoptera. Pollination in four species is Ficus not onlycarried out by one pollinator insect species per Ficus but by two or even three pollinatorinsect species and one pollinator species can pollinate more than one species Ficus.2Frequency distribution analysis shows the number of pollinator frequencies foundin four species Ficus. The results of the diversity index analysis showed that thediversity of pollinators in the four species was Ficus low. The regression analysisshowed a very low addition for each increase in one unit diameter, while the results ofthe correlation analysis showed that the diameter of syconia and the number ofpollinator insects were not correlated.Keywords: Association of pollinator species, Ficus spp., Batuputih Nature Park.

Abstract

ABSTRACT Birds that are not able to adapt to changes in land from forest to non-forest will look for a place of removal to become a new area of life. The use of space in the forest profile, both vertically and horizontally in various habitat types, shows a close relationship between birds and their habitat, especially in terms of adaptation patterns. The vertical distribution of bird species can be seen from the spatial stratification of the forest profil.The purpose of this study was to determine the diversity of bird species in several habitat profiles in the Protected Forest of Mount Mahawu, Masarang dan Tampusu. The Methods used in this study were the IPA-Count Method ( Index point of abudance) and the rapid assessment method. The results showed that there were 3 habitat profiles in the Mount Mahawu Protected Forest as many as 31 bird species with the Shannon-wiener Diversity Index of 2.27. There are 3 habitat profiles in the Mount Masarang Protection Forest as many as 34 bird species with the Shannon-wiener Diversity index of 2.15. There are 3 habitat profiles in the Mount Tampusu Protection Forest as many as 27 bird species with a Shannon wiener Diversity index of 2.31. The total habitat profile is 4 profiles, 43 species, 34 genera, 23 families with the shannon-wiener Diversity index of 6.73. Keywords : Birds, Diversity of bird species, Protected Forest of Mt. Mahawu, Masarang and Tampusu
