Abstract

Tea plantations can provide microclimate conditions for many epiphytic species, including orchids, but information on their diversity is not yet available. Epiphytic orchid diversity study has been carried out at the Nirmala Tea Plantation, Bogor, West Java. The main objective of this study was to reveal the diversity of epiphytic orchids in the Nirmala Tea Plantation. The data were obtained by vegetation analysis using the purposive sampling method by making 54 plots sized 5 x 5m2 at two different altitudes, 1050 and 1500 masl. The quantitative data were analyzed by calculating the critical value and morisita indices. The correlation between epiphytic orchid and microclimate variables was processed using Spearman bivariate correlation, performed using Canonical Correspondence Analysis. A total of 15 epiphytic orchids were found at an altitude of 1050 m asl and 10 species of epiphytic orchids at an altitude of 1500 m asl. Seven species, Agrostophyllum longifolium Rchb.f., Appendicula reflexa Blume, Bulbophyllum sp.2, Dendrochilum sp., Eria sp.1, Flickingeria sp, Pholidota carnea Lindl, were found at both altitudes. The diversity of epiphytic orchids is affected by altitude, light intensity, and wind speed. The distribution pattern of epiphytic orchids in Nirmala Tea Plantation is clumped. The results of this study report the diversity of orchids grown in tea plantations for the first time. This information is helpful for the cultivation and conservation of orchid diversity in the future.

Abstract

Myrmecophytes or locally known as simbagh utak are common medicinal plants used by locals in Bengkulu, especially in South Bengkulu, for treating various diseases. Despite their potential as medicines, there is no report on biotic factors can be used to indicate of Myrmecophytes species’ richness and habitat suitability. The objectives of this research were to analyze the Myrmecophytes’ species richness and habitat suitability. This study used the purposive sampling method by exploring the area where Myrmecophytes were commonly found. The biotic factors of Myrmecophytes were analyzed by identifying the tree host, the other epiphyte plant grew around them, and animal occupants on the tuber of the Myrmecophytes. The Myrmecophytes distribution was analyzed by using ArcGIS10.1. The results showed that there were two species of Myrmecophytes, namely Hydnophytum formicarum and Myrmecodia tuberosa in the study area. The Myrmecophytes attached and hung in 9 species of host trees. The characteristics of host trees are high trees with large diameter, mostly rough-barked; some were cracked and mossy. The highest frequency of host trees included Hevea brasiliensis and Durio zibethinus. Myrmecophytes coexisted with 12 species of epiphytes. Epiphyte plants like Dendrobium sp. and Drymoglossum piloselloides can be used to indicate the presence of Myrmecophytes. Ants made up the most predominantly animal found living inside the tubers of Myrmecophytes, with some cockroaches and termites found at the tuber of Hydnophytum. Information on species' richness and habitat suitability of Myrmecophytes can serve as supporting data for conservation efforts in Bengkulu to prevent the extinction of this species.

Abstract

Hoya is a tropical flowering plant that has great potential as an export commodity. It needs to be cultivated to ensure its sustainability in nature. Information about the suitable habitat of Hoya was not widely known yet. This study aimed to compare the habitat characteristics of several species of Hoya. The research was conducted by exploring the sample plots determined by purposive sampling based on the differences of habitat characteristics. The biotic components observed were phorophyte species type and the number of individual of each Hoya species. The abiotic components measured in each plot were altitude and geographical position, air temperature, humidity, light intensity, wind speed, and canopy cover. Hoya ‘s diversity was analyzed using the Shannon Winner Index. Environmental factor data and biotic factors were analyzed with Canoco for Windows 4.5 software. There were 6 species of Hoya namely Hoya multiflora, Hoya imperialis, Hoya vitellinoides, Hoya hasseltii, Hoya campanulata and Hoya lacunosa found in this study. The highest biodiversity index was obtained in an altitude of 700-800 m.a.s.l (H’=1.41) and in hillsides area (H’=1.3). Hoya ‘s most frequent phorophyte was Schima wallichii. Factors affecting the presence of Hoya in the phorophytes were the position of attachment to the main stem and the rough surface characteristics of the tree. Hoya ‘s preference place was on the bark fracture. Abiotic factors that most influencing the existence of Hoya were air humidity and canopy cover. The data of this research can be used as basic information for carried out the conservation efforts and cultivation strategy in the future.

Abstract

Myrmecophyte is a common medicinal plant used by local people in Indonesia for treating various diseases especially in Papua. Bengkulu province is one of the Myrmecophyte habitats, but there has no report on its identity and distribution. The objectives of this research were to identify the diversity and analyze the Myrmecophytes distribution as well as factor affecting its presence. This study used purposive sampling method by exploring the area where Myrmecophytes commonly found. The Myrmecophyte distribution based on host tree was analyzed using Morishita index and the autecological analysis of abiotic factors was performed using Principal Component Analysis (PCA) generated from Minitab 16. The results of this research showed that there were two species of Myrmecophytes in Bengkulu province, namely Hydnophytum formicarum and Myrmecodia tuberosa, as well as two variants of M. tuberosa i.e. M. tuberosa ‘armata’ and M. tuberosa ‘siberutensis’. The distribution of Myrmecophytes based on host tree was mostly randomly scattered in Central Bengkulu regency, Seluma, North Bengkulu, South Bengkulu, and Kaur. Their distributions were affected by light intensity and temperature. The data of this research can be used as basic information for carried out conservation efforts in Bengkulu province. The abundance of Myrmecophytes is also used as a source of additional income for local people in Bengkulu province.

Abstract

Nepenthes occur in various habitat types in West Kalimantan. But some species are categorized as vulnerable on the IUCN red list. Autecological studies of Nepenthes spp. are required for species management and conservation. The study aimed to analyze species diversity, distribution pattern, association, and environmental factors that correlated with Nepenthes spp. at peat swamp and heath forest in Pematang Gadung. Data was collected in September 2021 by purposive sampling on 60 plots measuring 3 x 3 m2 in each habitat type. Species diversity was analyzed based on the presence and abundance of species in the plots. The distribution pattern was determined using a standardized Morisita index (Ip). Meanwhile, the association type was determined based on the Jaccard index (JI). Environmental data were analyzed by Canonical Correspondence Analysis (CCA) using Past Version 4.03. This study found six wild species in a peat swamp and four species in a heath forest. The population of Nepenthes spp. has clumped distribution pattern with Ip>0. Nepenthes spp. are associated with plants such as Barringtonia racemosa, Syzygium sp., Nephrolepis biserrata, and Campnosperma auriculatum. The result of CCA revealed that environmental factors in both habitat types affected the presence of each Nepenthes species. The air temperature, humidity, soil moisture, and light intensity show different influences on different species.

Abstract

Oil palm has been widely studied regarding growth and development, water use, productivity, and other economically relevant functions. However, not much is known about the hydraulic conductivity of oil palm root systems and how xylem vessels perform their function to transport water from roots to shoots so far. This information is needed to describe oil palm strategies to maintain water status, especially in oil palms that grow under various soil hydrological regimes. To investigate the root hydraulic performance, we measured mean xylem vessel diameter (D), vessel density (VD), vessel lumen area (Alumen), and potential hydraulic conductivity (Kp) for oil palm root samples in seasonally flooded riparian and well-drained sites at Harapan Jambi Forest. The result showed that D, Alumen, and Kp increased with increasing root diameter at both plantation types. On the contrary, VD significantly decreased with increasing root diameter. Potential hydraulic conductivity (Kp) in riparian sites was smaller than in well-drained sites and significantly different in root diameter >2-5 and >5-10 mm and related to both plantation types. The low potential hydraulic conductivity of root xylem vessels and the narrowing of xylem vessel lumen that occurs in oil palm roots in the seasonally flooded riparian sites were presumed as adaptation mechanisms to maintain water supply from the roots to the shoot in oil palm plants in these sites.

Abstract

Forests are important habitats that support an ecosystem consisting of various types of plants that have production potential and litter decomposition rates. This research aims to find out how to calculate the production and decomposition rate of litter in homogeneous forest and heterogeneous forest terrestrial ecosystems. The research was carried out in homogeneous and heterogeneous forest areas in the IPB University campus area, Bogor Regency, West Java Province. The sampling process seemed to be carried out using 1x1 m nylon mesh litter trap method for 5 weeks. The results of the research show that the composition of the species that grow in heterogeneous forest areas is Kisabun (Filicium decipien), Sawo kecik (Manilkara kauki), Bisbul (Diospyros blancoy), Water guava (Eugenia aduea), Matoa (Pometia pinnata), Pinus (Cupressus lusitanica), and Meranti (Shorea sp), while in the homogeneous forest ecosystem is the rubber tree (Hevea brasiliensis). The amount of waste collected in heterogeneous forest ecosystems is greater than in homogeneous forest ecosystems (Rubber forests), namely 98 grams and 5.2 grams respectively with results in heterogeneous forest ecosystems of 7.2 grams dry weight from 10 grams wet weight, whereas in homogeneous forest ecosystem (rubber forest 0.8 grams dry weight from 2 grams wet weight). The decomposition rate of litter in heterogeneous ecosystems is 0.21 grams/year, while in rubber forest ecosystems it is 0.17 grams/year.
