Food Selection by Northern Yellow-Cheeked Crested Gibbons (Nomascus Annamensis)In Northern Cambodia
Food Selection by Northern Yellow-cheeked Crested Gibbons (Nomascus annamensis)in Northern Cambodia Naven Hon A thesis submitted to Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity School of Biological Sciences Victoria University of Wellington New Zealand 2016 i Abstract Tropical regions have extremely high plant diversity, which in turn supports a high diversity of animals. However, not all plant species are selected by animals as food sources, with some herbivores selecting only specific plants as food as not all plants have the same nutrient make up. Animals must select which food items to include in their diets, as the amount and type of nutrients in their diet can affect lifespan, health, fitness, and reproduction. Gibbon populations have declined significantly in recent years due to habitat destruction and hunting. Northern yellow-cheeked crested gibbon (Nomascus annamensis) is a newly described species, and has a limited distribution restricted to Cambodia, Laos and Vietnam. The northern yellow-cheeked crested gibbons play an important role in seed dispersal, yet little is currently known about this species, including its food selection and nutritional needs. However, data on food selection and nutritional composition of selected food items would greatly inform the conservation of both wild and captive populations of this species. This study aims to quantify food selection by the northern yellow-cheeked crested gibbons by investigating the main plant species consumed and the influence of the availability of food items on their selection. The study also explores the nutritional composition of food items consumed by this gibbon species and identifying key plant species that provide these significant nutrients. -
Silvestrol Induces Early Autophagy and Apoptosis in Human Melanoma Cells Wei-Lun Chen1, Li Pan2, A
Chen et al. BMC Cancer (2016) 16:17 DOI 10.1186/s12885-015-1988-0 RESEARCH ARTICLE Open Access Silvestrol induces early autophagy and apoptosis in human melanoma cells Wei-Lun Chen1, Li Pan2, A. Douglas Kinghorn2, Steven M. Swanson1,3 and Joanna E. Burdette1* Abstract Background: Silvestrol is a cyclopenta[b]benzofuran that was isolated from the fruits and twigs of Aglaia foveolata, a plant indigenous to Borneo in Southeast Asia. The purpose of the current study was to determine if inhibition of protein synthesis caused by silvestrol triggers autophagy and apoptosis in cultured human cancer cells derived from solid tumors. Methods: In vitro cell viability, flow cytometry, fluorescence microscopy, qPCR and immunoblot was used to study the mechanism of action of silvestrol in MDA-MB-435 melanoma cells. Results: By 24 h, a decrease in cyclin B and cyclin D expression was observed in silvestrol-treated cells relative to control. In addition, silvestrol blocked progression through the cell cycle at the G2-phase. In silvestrol-treated cells, DAPI staining of nuclear chromatin displayed nucleosomal fragments. Annexin V staining demonstrated an increase in apoptotic cells after silvestrol treatment. Silvestrol induced caspase-3 activation and apoptotic cell death in a time- and dose-dependent manner. Furthermore, both silvestrol and SAHA enhanced autophagosome formation in MDA-MB-435 cells. MDA-MB-435 cells responded to silvestrol treatment with accumulation of LC3-II and time-dependent p62 degradation. Bafilomycin A, an autophagy inhibitor, resulted in the accumulation of LC3 in cells treated with silvestrol. Silvestrol-mediated cell death was attenuated in ATG7-null mouse embryonic fibroblasts (MEFs) lacking a functional autophagy protein. -

Background Dillenia suffruticosa (Dilleniaceae), or “shrubby simpoh”, is a large shrub or small tree occasionally cultivated as an edible and medicinal plant or as an ornamental (Staples and Herbst 2005, HPWRA 2015). D. suffruticosa gained a KISC status of “Early Detection” in 2011, when it was detected during surveys for another KISC target in Wailua Homesteads. Plants were removed shortly afterwards based on expert opinion of its invasiveness on Oahu and the belief that it was not known elsewhere on Kauai. However, additional locations have been detected during 2015-2017 surveys. Thus, the purpose of this prioritization assessment report is to reevaluate whether KISC should attempt eradication (i.e. accept “Target” status) by scoring and comparing D. suffruticosa to other “Early Detection” species known to Kauai (See Table 5 in KISC Plant Early Detection Report for status terminology). -

Ranwala 1 Department of Zoology, Open University of Sri Lanka, Nawala, Nugegoda 2 Department of Botany, The Open University of Sri Lanka, Nawala, Nugegoda 3 Department of Plant Sciences, University of Colombo, Colombo 03 Date Received: 20-04-2013 Date Accepted: 29-10-2013 Abstract Dillenia suffruticosa (Griffith) Martelli, that spreads fast in low-lying areas in wet zone of Sri Lanka is currently listed as a nationally important Invasive Alien Species that deserves attention in ecological studies. Thus, impact of this woody invader on physical, chemical properties of soil and below and above ground flora was investigated. Five sampling sites were identified along a distance of 46km from Avissawella to Ratnapura. At each site, two adjacent plots [1m x10m each for D. suffruticosa present (D+) and absent (D-)] were outlined. Physical and chemical soil parameters, microbial biomass and number of bacterial colonies in soil were determined using standard procedures and compared between D+ and D- by ANOVA using SPSS. Rate of decomposition of D. suffruticosa leaves was also determined using the litter bag technique at 35% and 50% moisture levels. Above ground plant species richness in sample stands was compared using Jaccard and Sorenson diversity indices. Decomposition of D. suffruticosa leaves was slow, but occurred at a more or less similar rate irrespective of moisture content of soil. -

To conserve plants biodiversity, many local governments in Indonesia propose to cooperate with LIPI to build botanical gardens. Sambas botanical garden with an area ± 300 ha in West Kalimantan is one of a botanical garden which is under construction. As new exploration site, many biodiversity in this area has not been entirely explored yet including its medicinal plants. Methods used in this study including field survey and interview techniques. The objective of this study is to explore a biodiversity of medicinal plants in that area. This study identified 30 medicinal plants, representing 20 families and 25 genera. It indicated that Sambas botanical garden has many highly potential values of medicinal plants. Therefore, a proper management including medicinal plant for this area is strongly required. Keywords: Sambas, botanical gardens, medicinal plants INTRODUCTION Although Sambas Botanical Garden is predicted has Indonesian flora plays an important role in the great diversity on medicinal plants but information world biodiversity as contributes to 15.5% of total world about medicinal plants and uses in this area is very lack flora. However, it is under threatened due to high rate [4]. -

Information is provided on how these organisms are collected and processed. The types of bioassays are indicated in which initial extracts, chromatographic fractions, and purified isolated compounds of these acquisitions are tested. Several promising biologically active lead compounds from each major organism class investigated are described, and these may be seen to be representative of a very wide chemical diversity. -

All vascular plants were enumerated and identified. Importance value index (IVI) was computed to characterize the floristic composition. To capture different aspects of species diversity, we considered five different indices. The mean stem density was 7585 stems per ha. In total 36797 vascular plants representing 348 species belong to 227 genera in 89 families were identified within 5-ha of a coastal hill forest that is comprises 4.2% species, 10.7% genera and 34.7% families of the total taxa found in Peninsular Malaysia. Based on IVI, Agrostistachys longifolia (IVI 1245), Eugeissona tristis (IVI 890), Calophyllum wallichianum (IVI 807), followed by Taenitis blechnoides (IVI 784) were the most dominant species. The most speciose rich families were Rubiaceae having 27 species, followed by Dipterocarpaceae (21 species), Euphorbiaceae (20 species) and Palmae (14 species). According to growth forms, 57% of all species were trees, 13% shrubs, 10% herbs, 9% lianas, 4% palms, 3.5% climbers and 3% ferns.
