  • Dipterocarps
    1682 TROPICAL ECOSYSTEMS / Dipterocarps Dipterocarps B Krishnapillay, Forest Research Institute Malaysia, Kepong, Malaysia & 2004, Elsevier Ltd. All Rights Reserved. Introduction The dipterocarp forests of Southeast Asia constitute a dominant and particularly valuable component of the world’s tropical rainforest. As a family of plants, Dipterocarpaceae may perhaps hold the distinction of being the best-known trees in the tropics. Their ecosystems are extremely diverse. They are uneven in their age and multilayered. They grow all the year round under warm temperatures and on sites where there is a large amount of rainfall. However, those growing in the seasonal forest are generally medium sized with the tallest trees being around 20 m with a maximum diameter of about 50 cm. Generally dipterocarps have been observed to occur on soils with very low fertility. Currently the dipterocarps dominate the international tropical timber market, and therefore play an important role in the economy of many Southeast Asian countries. In addition to Figure 1 Phytogeographical distribution of the family Diptero- timber, this family of trees also produces other non- carpaceae worldwide. timber products like resins and oleoresins. 3.

    The Ectomycorrhizal Fungal Community in a Neotropical Forest Dominated by the Endemic Dipterocarp Pakaraimaea dipterocarpacea Matthew E. Smith1*, Terry W. Henkel2, Jessie K. Uehling2, Alexander K. Fremier3, H. David Clarke4, Rytas Vilgalys5 1 Department of Plant Pathology, University of Florida, Gainesville, Florida, United States of America, 2 Department of Biological Sciences, Humboldt State University, Arcata, California, United States of America, 3 Department of Fish and Wildlife Resources, University of Idaho, Moscow, Idaho, United States of America, 4 Department of Biology, University of North Carolina Asheville, Asheville, North Carolina, United States of America, 5 Department of Biology, Duke University, Durham, North Carolina, United States of America Abstract Ectomycorrhizal (ECM) plants and fungi can be diverse and abundant in certain tropical ecosystems. For example, the primarily paleotropical ECM plant family Dipterocarpaceae is one of the most speciose and ecologically important tree families in Southeast Asia. Pakaraimaea dipterocarpacea is one of two species of dipterocarp known from the Neotropics, and is also the only known member of the monotypic Dipterocarpaceae subfamily Pakaraimoideae. This Guiana Shield endemic is only known from the sandstone highlands of Guyana and Venezuela. Despite its unique phylogenetic position and unusual geographical distribution, the ECM fungal associations of P. dipterocarpacea are understudied throughout the tree’s range. In December 2010 we sampled ECM fungi on roots of P. dipterocarpacea and the co-occurring ECM tree Dicymbe jenmanii (Fabaceae subfamily Caesalpinioideae) in the Upper Mazaruni River Basin of Guyana. Based on ITS rDNA sequencing we documented 52 ECM species from 11 independent fungal lineages. Due to the phylogenetic distance between the two host tree species, we hypothesized that P.

  • 4. the Plant Diversity of Singapore
    FLORA OF SINGAPORE (Vol. 1: 37–46, 2019) 4. THE PLANT DIVERSITY OF SINGAPORE K.M. Wong & S.K. Ganesan The position of Singapore on the Sunda continental shelf is a special one, with the principal island originally about 540 km2 in extent, together with some 60 smaller islands at the southern exit to the Malacca Strait and near the confluence of the South China Sea and Karimata Strait just west of Borneo. Geographically at the equatorial extremity of the Malay Peninsula, Singapore is separated from the Riau islands to its south (principally the Karimun Islands, Batam and Bintan) by the Singapore Strait which includes the deeply scoured 204-m ‘Singapore Deeps’, a likely subsidence basin resulting from tectonic movements (Bird et al., 2006). While this Strait may seem able to restrict the dispersal of some organisms with interglacial and post- Pleistocene high sea levels, it probably was not an effective dispersal barrier during episodes of lowest sea levels, such as during the Last Glacial Maximum (LGM) at 18 ka. Then, it must have been in the path of a key land bridge between mainland Southeast Asia farther north and likewise exposed links to Java and other areas to the south (Ho, 1960; Morley & Flenley, 1987; Heaney, 1991; Voris, 2000; Bird et al., 2005). By contrast, the Johor Strait that separates Singapore from south Peninsular Malaysia is just about 10 m deep and 600 m wide at its narrowest. The Sundaland region on the Sunda continental shelf has seen climate shifts since even before the Pleistocene, sometimes associated with tectonic events.

  • Malay Vegetation
    Plant Formations in the Malayan BioProvince Peter Martin Rhind Malayan Mixed Lowland Dipterocarp Forest These forests occur from sea level to an altitude of about 750 m. In Endau-Rompin they can be broadly divided into two types. One is characterized by Dipterocarpus and Shorea, and mainly occurs at altitudes below 250 m, and is common, for example, in the valleys of the Endau River and its tributaries. The other is characterized by Dryobalanus aromatica, which occurs normally at altitudes below 300 m; it is common, for example, in the northeast and eastern areas of the Kinchin and Lamakoh valleys. Both these forests contain massive trees with canopies up to 30 m high and emergents reaching 45-50 m, and have many common trees. The main dipterocarps are Dipterocarpus baudi, D. concavus, D. costulatus, D. crinitus, D. gracilis, D. kerrii, Shorea acuminata, S. blumutensis, S. maxwelliana, S. ovalis, S. paevifolia, S. pauciflora, S. singkawang and the endemic S. bentongensis (Dipterocarpaceae). Dryobalanops aromatica is distributed gregareously in various river valleys while the endemic Hopea johorensis (Dipterocarpaceae), has a more patchy distribution but is often found in treefall gaps. Other large trees include Artocarpus lanceifolius, Coelostegia borneensis, Dialium platysepalum, Dillenia excelsa, Dyera costulata, Endospermum malaccensis, Koompassia malaccensis, Parkia speciosa, Pouteria malaccensis, Scaphium macropodum, Swintonia floribunda var. penangiana and the endemic Sarcotheca laxa var. sericea (Oxalidaceae). Second tier species include Agostistachys borneensis, Aporusa microstachya, Elateriospermum tapos, Pimelodendron griffithianum, Horsfieldia superba, Knema furfuracea, Myristica iners, Xerospermum noronhianum and the endemic Dillenia albiflos (Dilleniaceae) and Schoutenia furfuracea (Tiliaceae). Palms are also significant components with Oncospermum horridula being the most common species.

During the Mid-Miocene Climatic Optimum [MMCO, ~14 to 17 million years (Ma) ago], global temperatures were similar to predicted temperatures for the coming century. Limited megathermal paleoclimatic and fossil data are known from this period, despite its potential as an analog for future climate conditions. Here, we report a rich middle Miocene rainforest biome, the Zhangpu biota (~14.7 Ma ago), based on material preserved in amber and associated sedimentary rocks from southeastern China. The record shows that the mid-Miocene rainforest reached at least 24.2°N and was more widespread than previously estimated. Our results not only highlight the role of tropical rainforests acting as evolutionary museums for biodiversity at the generic level but also suggest that the MMCO probably strongly shaped the East Asian biota via the northern expansion of the megathermal rainforest biome.

  • Phylogeny of the Tropical Tree Family Dipterocarpaceae Based on Nucleotide Sequences of the Chloroplast Rbcl Gene1
    American Journal of Botany 86(8): 1182±1190. 1999. PHYLOGENY OF THE TROPICAL TREE FAMILY DIPTEROCARPACEAE BASED ON NUCLEOTIDE SEQUENCES OF THE CHLOROPLAST RBCL GENE1 S. DAYANANDAN,2,6 PETER S. ASHTON,3 SCOTT M. WILLIAMS,4 AND RICHARD B. PRIMACK2 2Biology Department, Boston University, Boston, Massachusetts 02215; 3Harvard University Herbaria, 22 Divinity Avenue, Cambridge, Massachusetts 02138; and 4Division of Biomedical Sciences, Meharry Medical College, 1005 D. B. Todd, Jr. Boulevard, Nashville, Tennessee 37208 The Dipterocarpaceae, well-known trees of the Asian rain forests, have been variously assigned to Malvales and Theales. The family, if the Monotoideae of Africa (30 species) and South America and the Pakaraimoideae of South America (one species) are included, comprises over 500 species. Despite the high diversity and ecological dominance of the Dipterocar- paceae, phylogenetic relationships within the family as well as between dipterocarps and other angiosperm families remain poorly de®ned. We conducted parsimony analyses on rbcL sequences from 35 species to reconstruct the phylogeny of the Dipterocarpaceae. The consensus tree resulting from these analyses shows that the members of Dipterocarpaceae, including Monotes and Pakaraimaea, form a monophyletic group closely related to the family Sarcolaenaceae and are allied to Malvales. The present generic and higher taxon circumscriptions of Dipterocarpaceae are mostly in agreement with this molecular phylogeny with the exception of the genus Hopea, which forms a clade with Shorea sections Anthoshorea and Doona. Phylogenetic placement of Dipterocarpus and Dryobalanops remains unresolved. Further studies involving repre- sentative taxa from Cistaceae, Elaeocarpaceae, Hopea, Shorea, Dipterocarpus, and Dryobalanops will be necessary for a comprehensive understanding of the phylogeny and generic limits of the Dipterocarpaceae.

    Technical Guidelines for Reforestation at Ex-Coal-Mining Areas - Based on the outcomes of experimental reforestation activities at ex-coal-mining areas in South Kalimantan, Indonesia - Japan International Forestry Promotion and Cooperation Center (JIFPRO) March 2015 Technical Guidelines for Reforestation at Ex-Coal-Mining Areas - Based on the outcomes of experimental reforestation activities at ex-coal-mining areas in South Kalimantan, Indonesia - Eiichiro Nakama, Seiichi Ohta, Yasuo Ohsumi, Tokunori Mori and Satohiko Sasaki Japan International Forestry Promotion and Cooperation Center Fakhrur Razie, Hamdani Fauzi and Mahrus Aryadi Lambung Mangkurat University, Indonesia Japan International Forestry Promotion and Cooperation Center March 2015 Foreword During the past decades, deforestation and forest degradation continues especially in developing countries. According to the report of the Food and Agriculture Organization of the United Nation (FAO), approximately 13 million hectors of global forests have been lost annually due to forest land conversion to other land uses, forest fires and natural disasters, while reforestation and natural regeneration account for an increase of approx. 7.8 million hectors of forest cover. This means the net loss of global forest is estimated at 5.2 million hectors. Adverse impacts of forest conversion to farmland can be minimized as far as the land is properly used and managed in a sustainable manner. However, in some cases, problem soils are exposed and abandoned as degraded land. Deforestation by mining is a big issue these years. Problem soils such as strong acid soils and/or too much heavy metal soils appear at the ex-mining areas. In some cases it is too difficult to reforestate.

  • THE DISTRIBUTION of the DIPTEROCARPACEAE in THAILAND by Tern Sm Itinand (Read at Xitb Pacific Science Congress, Tokyo, 1St September 1966)
    THE DISTRIBUTION OF THE DIPTEROCARPACEAE IN THAILAND by Tern Sm itinand (Read at XItb Pacific Science Congress, Tokyo, 1st September 1966) ABSTRACT The family Dipterocarpaceae is represented in Thailand by 9 genera and 6 3 species, and can be classified into 2 groups, evergreen and deciduous or xerophytic. The majority belong to the evergreen, which is scattered all over the country either in gallery forest (Dij;tero­ carpus alatus, VaLica cinerea and Hopea odorata), along the hill streams (Dipterocarpus oblongifolius and V atica odorata), in the low-lying land (Dij;terocarpus baudii, D. dyeri, D. gmcilis, D. clwrtaceus, D. ken·ii, Slwrea and f-loj;ea spp.), or on bill slopes (Dij;terocarpus cnslatus, D. gt·andiflorus, D. Tetusus, D. turbinatus, D . IIWC1"0carpus, Hopea odomta, I-Iopea f enea and S!wrea talura). Only 5 xerophytic species are represented (Dipterocmpus obtusifolius, D. tuberculatus, D. intn·catus, Shorea obtusa and Pe11taC11·1e suavi.s), occupying either the high plateau or ridges, and forming a climatic forest type, the Dry Deciduous Diptero­ carp forest. The highest elevation reached by the Dipterocarps is 1300 m.a.s.l. (D1j;terocarpus tuberculatus, D. obtusifolius, Shot·ea obtusa and Pentacme suavis). Parashortea stellata and Shorea Togersiana follow the Tenesserim tract, while Cotylelobium lanceolatum, Balanocarpus heimii, Shorea curtisii, S. assamica var. globifera, S. guiso, S. faguetiana, S. hemsleyana, S. sumatrana, S. mae1·optera, S. glauca S. j;arv lfolia, I-Iopea pedicellata, I-I. lat1jolia, Vatica staj;fiana, and V. lowii are confined to the Peninsular region not beyond the latitude 1 o·N. Species found only in the Northeastern region are I-Iopea 1·eticulata and I-I.

In a comparative study of the phylogeographic patterns of two closely related dipterocarp species, Dryobalanops aromatica C.F.Gaertn. and D. beccarii Dyer, we inves- tigated how changes in land area associated with changes in climate affected large-scale genetic structure. We examined the genetic variation of D. aromatica, collected from nine populations throughout the Sundaic region, and of D. beccarii, collected from 16 populations mainly in Borneo, using seven polymorphic microsatellite markers. The two species were clearly distin- guishable in the STRUCTURE analysis, although hybridisation probably occurred in sympatric populations and also in several other populations. The D. aromatica populations were divided into two main groups by the STRUCTURE analysis: Malay–Sumatra and Borneo. Mixing of the Sumatra and Borneo clusters occurred on the Malay Peninsula, supporting the hypothesis that tropical rainforests expanded over a dried Sunda Shelf during the last glacial period. The two main genetic clusters might have been formed by repeated cycles of fluctuation in land area.

Here we present the first karyomorphology of Marquesia macroura (2n=22) (Monotoideae), as well as of four species (2n=22) of four genera in tribe Dipterocarpeae and five species (2n=14) of tribe Shoreae in Dipterocarpoideae. Comparisons within Dipterocarpaceae and with Sarcolaenaceae (2n=22) sister to Dipetrocarpaceae in the light of phylogenetic relationships show that the basic chromosome number x=11 is plesiomorphic and x=7 apomor- phic in Dipterocapaceae. Based on available information, tribe Shoreae (x=7) has a uniform karyotype where all chromosomes have a centromere at median position, while the rest of the family (x=11) have a diverse karyotype in terms of the frequency of chromosomes with a centromere at median, submedian and subterminal position. We discussed the meaning of lability of karyotype in chromosome evolution. Keywords Basic chromosome number, Chromosome evolution, Dipterocarpaceae, Karyomorphology. Dipterocarpaceae (Malvales) are a family of 16 gen- x=10, and five genera Dryobalanops, Hopea, Neobala- era and 680 species distributed in tropical regions of nocarpus, Parashorea and Shorea of tribe Shoreae all the Old World, especially in the rain forests of Malesia have x=7.
