Inventory, identification key, mapping, and management recommendation of bamboo species in the ecology park, center for plant conservation, botanic gardens–LIPI, Bogor Regency, West Java. This study aimed to make an inventory of bamboo species to provide an identification key, a distribution map of those bamboos, as well as, a recommendation on bamboo management in the Ecology Park. The study was conducted in January-February 2019 using the exploration method, located in the Ecology Park, Center for Plant Conservation, Botanic Gardens, Campus of Cibinong Science Center–Botanic Gardens (CSC–BG), LIPI, Cibinong, Bogor, West Java. The bamboo herbarium specimens were made to determine the bamboo species found in the Ecology Park. The bamboo specimens were processed and deposited in the Herbarium Bogoriense (BO). The morphology characters of bamboo were described and to be used to determine the species and also to provide an identification key. The distribution map of bamboo in the Ecology Park created and it was overlapped with the existing map of the Ecology Park area. The bamboo management recommendation was made based on the data of bamboo inventory and mapping. The results showed that there are three species of bamboo from 40 clumps found in the Ecology Park, namely Bambusa vulgaris (bambu ampel), Gigantochloa apus (bambu tali), and G. pseudoarundinacea (bambu andong). These bamboos were alleged spontaneous collection and mostly distributed near the lake and along the road. An identification key to the species and a distribution map of bamboo species in the Ecology Park were presented. These bamboos play an important role in the Ecology Park to maintain water availability and to help to prevent a landslide. It is recommended that bamboo clumps in Ecology Park need to be tidied by making a fence and thinning of bamboo clumps needs to be done at least every 2 years. The management staff need to enrich the bamboo species in the Ecology Park, particularly ornamental and endemic bamboo of Indonesia, such as Schizostachyum brachycladum (bambu gading) and Dinochloa scandens (bambu cangkoreh), planted in accordance with the bioregion where the species come from.

AbstrakArea konservasi ex situ, Ecopark Cibinong Science Center-Botanic Gardens (CSC-BG), membutuhkan strategi pemeliharaan tanaman koleksi yang tepat untuk mendukung kesehatan dan keberlanjutan koleksinya. Serangan benalu atau tumbuhan parasit tidak hanya dapat merusak estetika, namun juga menghambat pertumbuhan dan perkembangan, bahkan membunuh tanaman koleksi. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis benalu dan distribusi spasial dari sebaran benalu di Ecopark CSC-BG. Pengumpulan spesimen dan data, meliputi jenis dan jumlah benalu, jenis dan kondisi inang, habitat menggunakan metode jelajah di seluruh area ini. Ditemukan empat jenis benalu dari suku Lorantaceae, yaitu Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh., dan Dendrophthoe sp. Benalu tersebut tersebar di bioregion Blok 1, Jawa-Bali, Kalimantan, Sumatra, dan Papua. Beberapa faktor ekofisiologi yang disarankan untuk diperhatikan dalam distribusi benalu adalah tinggi inang, ekspos cahaya pada tajuk bagian atas inang, kepadatan tanaman koleksi, keterbukaan atau ekspos cahaya matahari pada habitat. Indeks keanekaragaman (H’) dan indeks kemerataan (E’) benalu yang ditemukan menunjukkan H’ = 1,29 dan E’ = 0,93. Hasil analisis pola spasial, keberadaan benalu relatif merata di seluruh bagian Ecopark CSC-BG, dengan keragaman jenis tertinggi berada di bioregion Jawa-Bali, Sumatra, dan Kalimantan. Kesimpulan penelitian ini 4 jenis benalu yang ditemukan di Ecopark CSC-BG dengan nilai indeks keanekaragaman jenis benalu tergolong sedang dengan pola sebaran merata.AbstractThe Ecopark Cibinong Science Center-Botanic Gardens (CSC-BG), requires the right collection of plant maintenance strategies to support the health and sustainability of the collection. Attack by parasites or parasitic plants can not only destroy aesthetics, but also inhibit growth and development, and even kill the collected plants. This study aims to determine the diversity of parasite types and the spatial distribution of the distribution of parasites in Ecopark CSC-BG. Collection of specimens and data, including the type and number of parasites, types, and conditions of the host, habitat using the roaming method throughout this area. Four types of parasites were found from the Loranthaceae tribe, namely Dendrophthoe pentandra (L.) Miq., Scurrula atropurpurea (Blume) Danser, Macrosolen cochinchinensis (Lour.) Tiegh., and Dendrophthoe sp. These types of parasites are scattered in the Block 1 bioregion, Java-Bali, Kalimantan, Sumatra, and Papua. Some of the recommended ecophysiological factors to consider in the distribution of mistletoes were host height, light exposure to the upper canopy of the host, plant collection density, openness, or exposure to sunlight in the habitat. The diversity index (H') and evenness index (E') of mistletoes found were 1.29 and 0.93, respectively. The results of spatial pattern analysis, the presence of mistletoes was relatively evenly distributed throughout the garden, with the highest species diversity found in the Java-Bali, Sumatra, and Kalimantan Bioregions. This study concludes that there were 4 species of mistletoes found in Ecopark CSC-BG with a moderate diversity index and an even distribution pattern.

Thermochemical Stability

New ceramic fibers, currently in various stages of commercial development, have been consolidated in intermetallic matrices such as γ-TiAl and FeAl. Fiber types include SiC, TiB2 and polycrystalline and single crystal Al2O3. This work required the development of techniques to characterize the thermochemical stability of these fibers in different matrices.SEM/EDS elemental mapping was used for this work. To obtain qualitative compositional/spatial information, the best realistically achievable counting statistics were required. We established that 128 × 128 maps, acquired with a 20 KeV accelerating voltage, 3 sec. live time per pixel (total mapping time, 18 h) and with beam current adjusted to give 30% dead time, provided adequate image quality at a magnification of 800X. The maps were acquired, with backgrounds subtracted, using a Noran TN 5500 EDS system. The images and maps were transferred to a Macintosh and converted into TIFF files using either TIFF Maker, or TNtolMAGE, a Microsoft QuickBASIC program developed at the Science Center. From TIFF files, images and maps were opened in either NIH Image or Adobe Photoshop for processing and analysis and printed from Microsoft Powerpoint on a Kodak XL7700 dye transfer image printer.

Three hitherto undocumented watercolours in the possession of the National Botanic Gardens, Dublin, are found to depict botanically interesting views of Falkland Islands' vegetation and an historically important painting of Port Louis about 1842, when it was the capital of the archipelago. From the evidence available it seems clear that these paintings were prepared by either Bartholomew J. Sulivan or his wife during a surveying voyage to the Falkland Islands in 1842–43, when he commanded the brig Philomel. Some associated herbarium specimens seem to have been collected by B. J. Sulivan during 1838 when he visited the Falkland Islands as Lieutenant aboard the surveying ketch Arrow.
