The purpose of this portion of the PASA obligation is to present previously published information on the tree and wood characteristics of selected secondary species growing m seven tropical countries. The format is concise and follows the outline developed for the second edition of the "Handbook of Hardwoods" published by HMSO, London. Species selected for review are well known in the source countries, but make up a very small component, if any, of their export trade. The reasons why these species play a secondary role in the timber harvest are discussed in the other accompanying PASA reports. ii INDEX Pages SURINAM 1-11 Audira spp. Eperu falcata Eschweilera spp. Micropholis guyanensis Nectandra spp. Ocotea spp. Parinari campestris Parinari excelsa Pouteria engleri Protium spp. -

DCorresponding author. Email: [email protected] Abstract. Leguminosae are one of the most diverse flowering-plant groups today, but the evolutionary history of the family remains obscure because of the scarce early fossil record, particularly from lowland tropics. Here, we report ~500 compression or impression specimens with distinctive legume features collected from the Cerrejón and Bogotá Formations, Middle to Late Paleocene of Colombia. The specimens were segregated into eight fruit and six leaf 5 morphotypes. Two bipinnate leaf morphotypes are confidently placed in the Caesalpinioideae and are the earliest record of this subfamily. Two of the fruit morphotypes are placed in the Detarioideae and Dialioideae. All other fruit and leaf morphotypes show similarities with more than one subfamily or their affinities remain uncertain. The abundant fossil fruits and leaves described here show that Leguminosae was the most important component of the earliest rainforests in northern South America c. 60–58 million years ago.

Large‐Scale Genomic Sequence Data Resolve the Deepest Divergences in the Legume Phylogeny and Support a Near‐Simultaneous Evolutionary Origin of All Six Subfamilies
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Large‐scale genomic sequence data resolve the deepest divergences in the legume phylogeny and support a near‐simultaneous evolutionary origin of all six subfamilies Koenen, Erik J M ; Ojeda, Dario I ; Steeves, Royce ; Migliore, Jérémy ; Bakker, Freek T ; Wieringa, Jan J ; Kidner, Catherine ; Hardy, Olivier J ; Pennington, R Toby ; Bruneau, Anne ; Hughes, Colin E Abstract: Phylogenomics is increasingly used to infer deep‐branching relationships while revealing the complexity of evolutionary processes such as incomplete lineage sorting, hybridization/introgression and polyploidization. We investigate the deep‐branching relationships among subfamilies of the Leguminosae (or Fabaceae), the third largest angiosperm family. Despite their ecological and economic importance, a robust phylogenetic framework for legumes based on genome‐scale sequence data is lacking. We generated alignments of 72 chloroplast genes and 7621 homologous nuclear‐encoded proteins, for 157 and 76 taxa, respectively. We analysed these with maximum likelihood, Bayesian inference, and a multispecies coa- lescent summary method, and evaluated support for alternative topologies across gene trees. We resolve the deepest divergences in the legume phylogeny despite lack of phylogenetic signal across all chloroplast genes and the majority of nuclear genes. Strongly supported conflict in the remainder of nuclear genes is suggestive of incomplete lineage sorting. All six subfamilies originated nearly simultaneously, suggesting that the prevailing view of some subfamilies as ‘basal’ or ‘early‐diverging’ with respect to others should be abandoned, which has important implications for understanding the evolution of legume diversity and traits. -

Stand Structure and the Genetic Diversity of Koompassia
Sains Malaysiana 36(2)(2007): 233-242 Stand Structure and the Genetic Diversity of Koompassia malaccensis and Dryobalanops aromatica in Unlogged and Logged-over Stands (Struktur Dirian dan Kepelbagaian Genetik Koompassia Malaccensis dan Dryobalanops Aromatica pada Dirian yang Belum dan yang telah Dibalak) KIM SU LEE, RATNAM WICKNESWARI & CHEE YEN CHOONG ABSTRACT The disturbance level of two nearby logged stands, Compartment 118 and Compartment 69 were studied in Ulu Sedili Forest Reserve, Johor. The mean basal area for trees (trees ! 1 cm dbh) in logged stand of Compartment 118 showed 51% reduction in comparison to immediately before logging of the same stand. A similar level of reduction (47%) was observed for mean density of trees in Compartment 118. However, the mean basal area and mean density of tree were higher in 50-year logged Compartment 69 (21% and 122% respectively) compared to Compartment 118 before logging. Concurrently, we examined the effects of logging on genetic diversity of seedling, sapling and mature trees of two important timber species, Koompassia malaccensis and Dryobalanops aromatica using M13 universal primer (multilocus minisatellite DNA) and three other universally-primed primers. Mature trees of K. malaccensis showed 39% reduction in Shannon diversity index (H) in Compartment 69 compared to Compartment 118 before logging detected by M13 universal primer. This may be attributed to the small sample size of the species in Compartment 69. Reduction in H and polymorphic loci (P) for K. malaccensis was higher in seedlings, 5% and 56% respectively in Compartment 69 compared to mature trees (3% and 23% respectively). Contrastingly for seedlings and saplings of D. -

Technical Guidelines for Reforestation at Ex-Coal-Mining Areas
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. -

Latifah D, Wardani FF, Zulkarnaen RN. 2020. Seed germination, seedling survival and storage behavior of Koompassia excelsa (Leguminosae). Nusantara Bioscience 12: 46-49. Koompassia excelsa (Becc.) Taub. (Leguminosae) is an important component of many tropical rainforests as an emergent canopy tree. Knowledge and application of germination strategies and increasing seedling survival of this species in many conservation efforts are essential as it is endemic to several areas in Southeast Asia. This research investigated the effects of the different moisture levels of the sowing media on the germination and seedling survival percentage of K. excelsa. The seeds exhibited faster germination percentage and higher seedling survival when sown in media with 33.2%-moisture. The seeds appeared to have intermediate storage behavior. Thus, sowing seeds in 33.2%-moisture media may promote seedling survival, which is an important part of regeneration as well as conservation of K. excelsa. Keywords: Germination, Koompassia excelsa, media, seedling, storage INTRODUCTION orthodox (Sasaki 1976, Sasaki 1980), K. excelsa seeds have been cryopreserved successfully for long-term storage Koompassia excelsa is distributed across Southeast (Azman 2015) indicating the seed storage behavior was Asia, including Indonesia (Sumatera and Borneo Islands), intermediate. -
