Two new species of Endiandra (Lauraceae), i.e. Endiandra areolata Arifiani and Endiandra lanata Arifiani are described from New Guinea. Both species have staminal glands, but their form is different in the two species.ÃÂ Moreover, E. areolata Arifiani is characterized by its prominent areolation formed by the minor venation, and E. lanata Arifiani is easily recognized by the presence of a dense curly indument on its twig, leaves, inflorescences and flowers.

Flood events are often inundated rice fields and can cause flooding to surrounding areas (the lower reaches of the river) should not be underestimated (just blame the rainfall factor alone), but should be seen also internal factors of the techniques of rice cultivation in paddy fields. The purpose of research/study was to analyze the effect of flooding on the cultivation of paddy rice to infiltration and provide alternative solutions cultivation techniques to reduce flooding. The research method in this study is a survey method with the quantitative approach. Techniques flooding in paddy rice cultivation, especially irrigated cropping pattern rice 3 times a year have resulted in the formation of plow layer tread that is waterproof (hardpan). Waterproof coating that forms on the floor of paddy (rice surface) cannot infiltrate rainwater so that if there is a high-intensity rainfall in the rainy season, rice cannot hold the rain water will overflow and cause flooding to the area around the rice fields. Techniques inundation in lowland rice cultivation resulted in flooded paddy rice growth period in a rather long time (over 2 months), so that the aggregate soil is loose and prone to erosion and landslide potential. Anticipation of floods caused by wetland can be done by making the high rice fields higher than the height of the floodwaters that ever happened to the rice field and lowering the height of standing water in the paddy fields.

The aim of this study is to obtain basic descriptive account of structure and floristic composition of cacao based agroforestry in conserving tree species diversity in West Sumatera. An analysis of the composition and structure of three types of cacao based agroforestry system (AFS) [cacao - rubber (CR), cacao ? coconut (CC) and cacao multistrata (CM)] was conducted in April to June 2017. Data collection was done by using quadrat method of 20 x 20 meter plots with a total of 6 plots on each types of AFS. Herbarium specimens were collected and identified. Among all types of these AFS, CC was the most diverse floristically (H? = 1.02) with the highest total of species (10 species), followed by CM (9 species) and CR (7 species). CM has the highest tree density of 1108 trees per ha and the highest total of basal area (30.53 m2). We also did a comparison of the floristic composition of cacao based AFS with the nearest natural forest from previous study. There was a large decrease in the number of non-cocoa tree species from natural forest to AFS, from 139 to 6-9 species. The only native tree species found both in the forest and AFS is Pterospermum javanicum Jungh. It is concluded that three types of cocoa based AFS in West Sumatera were floristically different with natural forest.

Host plant preference amongst several fruit species was studied for two fruit fly species i.e. Bactrocera carambolae (Drew & Hancock) and Bactrocera dorsalis (Drew & Hancock), which both belong to B. dorsalis species complex. Both fruit fly species are known to be polyphagous and cause significant economic losses as pests of fruit crops. The aim of this research was to assess the host range of these major pests in Indonesia. The research was conducted at the Entomology Laboratory and Insect Specimen Collection Laboratory, Indonesian Center for Agriculture Biotechnology and Genetic Resource Research and Development, Bogor, West Java, Indonesia from June 2011 to March 2012. Comparative host preference for both species was studied with regard to malaya varieties of star fruit (Averrhoa carambolae), manalagi varieties of mango (Mangifera indica), guava aka water apple (Psidium guajava), citra water guava (Eugenia aquae), jamaica bol guava (Eugenia malaccenensis), and california papaya (Carica papaya). Our results suggest the strongest preference for malaya star fruit by B. carambolae followed by manalagi mango; and for california papaya followed by manalagi mango by B. dorsalis. The study also found that welahan variety star fruit is least preferred by both species of fruit fly.

Termites are a group of invertebrates abundant in forested habitats. In this study, we conduct an inventory and spatial analysis of the termite fauna of the UI campus. The survey records the presence of six termite species (Coptotermes curvignathus, Schedorhinotermes javanicus, Macrotermes gilvus, Microtermes insperatus, Odontotermes grandiceps, and Odontotermes javanicus), most of which had been reported by previous studies. The spatial analysis of termite nest distribution suggests a random scattering of termite nests in the UI campus.

Wetlands are suitable habitats for the coastal bird community. One of the important wetlands is located on Jakarta’s North Coast. Here, this study aims to assess the spatial biodiversity of birds in various land covers of wetlands on Jakarta’s North Coast. In total, there were 23 species belonging to 12 bird families. Ardeidae, Rallidae, and Silviidae bird families have more species compared to other families. The biodiversity H' values in the wetlands dominated by mangrove cover were the highest, at 2.527, followed by the wetlands having less mangrove cover and more water bodies and fish ponds only having H’ values equal to 1.811. The arboreal, small-to-medium-sized birds belong to Nectariniidae, Ploceidae, Silviidae, and Dicaeidae were widely distributed across all land cover. In contrast, the wetlands characterized by mangrove cover dominance combined with muddy substrate coasts were dominated by mid-large water birds belong to Anatidae, Scolopacidae, Ciconiidae, Rallidae, Ardeidae, Phalacrocoracidae, Anhingidae, and Alcedinidae. It is recommended to protect the mangroves and reforest the wetlands with mangroves to provide more habitats for the coastal bird community.

Amphibians and their geographical distribution are threatened by climate change, including speciesin West Java, Indonesia. It is estimated that 300 amphibian species are threatened, including the familyDicroglossidae. At the same time, information on how climate change impacts amphibian species inIndonesia is very limited. This study aims to assess and model the suitable habitat for the least concernAsian brackish frog, Fejervarya cancrivora (Gravenhorst, 1829), under the CMIP 5 RCP 8.5 futureclimate change scenario by 2070, analyzed using Maximum Entropy (MaxEnt). The models developedwith MaxEnt showed good predictivity, with an AUC value of 0.701. The models that inform theprecipitation of the wettest month, isothermality, and mean diurnal range variables have significantcontributions to make in shaping F. cancrivora geographical distributions. The models confirm that F.cancrivora had shifted its geographical distribution and had gained and lost habitats under a future climatechange scenario by 2070. F. cancrivora will lose 4,428 km2 of its current habitat and will gain 2,673km2 of new habitat. In total, climate change will cause F. cancrivora to lose its habitat by 1,755 km2.

Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.
