Abstract

The influence of elevation gradient has been investigated across different taxa. However, such studies are scarce for macrofungal communities. This study examined the community structure of Basidiomycota macrofungi across four elevations in Bukit Baka Bukit Raya National Park, Indonesia. Macrofungi were collected from randomly placed five 10 x 10 m plots at each altitude and identified at the genus level. The results showed that there were 32 genera belonging to 20 families. The NMDS ordination and ANOSIM confirmed that macrofungal composition and abundance do not differ between the studied altitudinal ranges.

Abstract

Orchids are one of the flowering plants that have many species and are widely distributed, as well as having different attractions and characteristics in each species and habitat. The aim of this research to inventory the types of orchids in Customary Forest Area of Cipta Karya Village, Bengkayang Regency. The research was conducted using the cruise method. The characteristics observed were the morphology of orchids such as roots, pseudobulbs, stems, leaves, and flowers. The inventory results found 13 species of orchids. Epiphytic orchids were found more commonly in this area, with a total of  9 species, while terrestrial orchids were found with 4 species. The epiphytic orchid species foundware composed of Appendicula sp., Bulbophyllum sp., Coelogyne speciosa, Cymbidium sp., Dendrobium crumenatum, Dendrobium anosmum, Luisia sp., Micropera pallida and Oberonia sp. The terrestrial orchid species found ware composed of Acanthephippium javanicum, Malaxis latifolia, Nephelaphyllum pulchrum, and Spathoglottis plicata.

Abstract

Pitcher plants (Nepenthes spp.) are supporting ecotourism activities plants because it has a unique morphologies. The Kapusin Nature Conservation Forest is a secondary forest that has potential as an ecotourism site because of its beauty and also the natural habitat of Nepenthes spp. This research aims to determine the types and relationships of Nepenthes spp. sin the Kapusin Nature Conservation Area. Sampling used the exploring method and then the results were identified by observing the morphologies of the stems, leaves and pitchers. There were 49 morphological characters observed, consisting of 29 qualitative characters and 20 quantitative characters. Relationships between individuals was cluster analyzed using the UPGMA (Unweighted Pair-Group Method with Arithmatic) method using NTSys (Numerical Taxonomy System) software version 2.02. The results obtained were 4 Nepenthes and 2 hybrid Nepenthes consisting of N. ampullaria, N. bicalcarata, N. mirabilis, N. gracilis, N. xtrichocarpa and N. xcoccines. The results of the grouping analysis showed that the Nepenthes found had a similarity rate of 53% and were divided into 4 clusters, namely cluster 1 consisting of N. ampullaria and N. xtrichocarpa species, cluster 2 of N. gracilis species, cluster 3 of N. mirabilis and N. xcoccines species. and cluster 4 species of N. bicalcarata.

Abstract

Wild Honey is produced directly from the hives of Apis dorsata bees or wild bees that live in forest areas. Wild Honey is produced through traditional methods that utilize plants and are not livestock. Plants that are utilized in the form of plant wood as artificial nests called tikung and flowers from bee food trees. The purpose of this study was to determine the types of plants as tikung wood and bee food trees and document the knowledge of traditional honey farmers about the ethnoecology of Batu Rawan Hamlet, Kapuas Hulu Regency. This study used purposive sampling method in determining respondents and 15 respondents were obtained, then continued with semi-structured interviews. Data analysis was conducted with citation frequency. The results showed that there were 5 species of tikung wood and 15 species of bee food trees belonging to 12 families. Fagraea fragrans, Shorea belangaran, Litsea resinosa, Gluta renghas, Shorea sp., are plant species used as tikung wood trees, the dominant species reported by respondents is Litsea resinosa which is 93.3%. Mesua hexapetala, Syzygium claviflorum, Barringtonia acutangula, Ternstroemia sp., Carallia brachiata, Teysmanniodendron sarawakanum, Syzygium sp., Gomphia serrata, Eugenia sp., Syzygium inophyllum, Timonius flavescens, Ixora mentangis, Syzygium attenuatum, Memecylon edule, Crudia teysmannii are plant species used as bee fodder trees, bee fodder tree species reported dominantly by respondents are Barringtonia acutangula species which is 100%.
