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.

    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.

    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.

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.

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.

    Maejo International Journal of Science and Technology ISSN 1905-7873 Available Online At

    i Maejo Int. J. Sci. Technol. 2009, 3(01), i Maejo International Journal of Science and Technology ISSN 1905-7873 Available online at www.mijst.mju.ac.th Editor's Note The year B.E. 2552 (A.D. 2009) has brought about a number of changes in connection with this journal. First, it is now entering its 3rd year of activity since its conception with its first volume and first issue being launched 2 years ago. Second, it is now a 100% e-journal (no more hard copies), which means an article can be published anytime as soon as it is ready (as always being the case from the beginning, however.) Thirdly, our managing editor, Dr. Weerachai Phutdhawong, the technical and key founder of this journal, has reluctantly left us for a new academic position at Kasetsart University. Without him from the start, this journal would never have been as it is now. He and the webmasters of Maejo University have jointly created a website for a journal which is freely, fully, and easily accessible. And this is most probably one of the factors that contribute to its unexpected and continuing popularity from the beginning as well as to the increasing international recognition of the journal now.* Lastly, the editor sincerely hopes that, with a well-laid foundation in store and a strong editorial committee at present, and despite his failing health after two years in office, which may result in a new editor for the journal in the near future, this journal will continue on well towards serving submitters, both local and abroad, as well as improving on its standard further.
