The largest genera are Shorea (360 species), Hopea (105 species), Dipterocarpus (70 species), and Vatica (60 species). Many are large forest emergent species, typically reaching heights of 40-70 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina and Malesia, with the greatest diversity and abundance in western Malesia. Some species are now endangered as a result of overcutting and extensive illegal logging. They provide valuable woods, aromatic essential oils, balsam, and resins. The dipterocarp family is generally divided into three subfamilies: Monotoideae: 3 genera, 30 species. Marquesia is native to Africa. Monotes has 26 species, distributed across Africa and Madagascar. Pseudomonotes is native to the Colombian Amazon. Pakaraimoideae: contains a single species, Pakaraimaea roraimae, found in the Guaianan highlands of South America. Dipterocarpoideae: the largest of the subfamilies, it contains 13 genera and 470-650 species. Distribution includes the Seychelles, Sri Lanka, India, Southeast Asia to New Guinea, but mostly in west Malesia, where they form the dominant species in the lowland forests. The Dipterocarpoideae can be divided into two groups (Ashton, 1982; and Maury-Lechon and Curtet, 1998): o Valvate-Dipterocarpi group (Anisoptera, Cotylelobium, Dipterocarpus, Stemonoporus, Upuna, Vateria, Vateriopsis, Vatica). The genera of this group have valvate sepals in fruit, solitary vessels, scattered resin canals, and basic chromosome number x = 11. o Imbricate-Shoreae group (Balanocarpus, Hopea, Parashorea, Shorea). The genera of this group have imbricate sepals in fruit, grouped vessels, resin canals in tangential bands, and basic chromosome number x = 7. A recent molecular study (Dayanandan et. al., 1999) suggest that the genus Hopea forms a clade with Shorea sections Anthoshorea and Doona, and should be merged into Shorea. A recent genetic study (Ducousso et. al. 2004) found that the Asian dipterocarps share a common ancestor with the Sarcolaenaceae, a tree family endemic to Madagascar. This suggests that ancestor of the Dipterocarps originated in the southern supercontinent of Gondwana, and that the common ancestor of the Asian dipterocarps and the Sarcolaenaceae was found in the India-Madagascar- Seychelles land mass millions of years ago, and were carried northward by India, which later collided with Asia and allowed the dipterocarps to spread across Southeast Asia and Malesia. Many members enlarged produce valuable gums- Gurjun balsam, wood oil, gum amine- and some yield a very good quality of camphor. The seeds are generally oleaginous. This family consists of the following generas: Anisoptera Cotylelobium Dipterocarpus Dryobalanops Hopea Marquesia Monotes Neobalanocarpus Pakaraimaea Parashorea Shorea Stemonoporus Upuna Vateria Vateriopsis Vatica Timbers The following table associates tree species, wood name and wood color.

Nesting behavior of Bornean immature Orangutan (Pongo pygmaeus wurmbii) in Nyaru Menteng Arboretum School, Palangka Raya, Central Kalimantan, Indonesia. Biodiversitas 21: 2172-2179. This research aimed at analyzing the nesting behavior of Bornean Orangutan (Pongo pygmaeus wurmbii) in Nyaru Menteng Arboretum, Palangka Raya, Central Kalimantan, Indonesia. The objects of observation were the immature orangutan nest, and the type of nest tree. The purposive sampling technique was used because not all immature Orangutan could make a nest. The Focal animal sampling method was used to determine the daily behavior and nets building activity. It involved observing and recording the behavior of five young Orangutans over a certain period of time and analyzing the nest made. The results of the study established that the daily activity of immature Orangutan on an average sequentially ranges from feeding 17.18%, moving 23.92%, resting 26.34%, and social behavior 32.57%.

Two mast fruiting events, both coinciding with El Niño/Southern Oscillation events, occurred 4 years apart, resulting in large fluctuations in fruit availability. Sun bear fruit availability decreased from 13 trees ha−1 fruiting month−1 during the mast fruiting to 1.6 trees ha−1 fruiting month−1 during the intermast period. Almost 100% of sun bear diet consisted of fruit during mast fruiting period, whereas sun bear diet was predomi- nantly insectivorous during intermast periods. The majority of sun bear fruit trees displayed ‘mast-fruiting’ and ‘supra-annual’ fruiting patterns, indicating sporadic productivity. Sun bears fed on 115 fruit species covering 54 gen- era and 30 families, with Ficus (Moraceae) being the main fallback fruit.

  • Emergence and Extinction of Dipterocarpaceae in Western India with Reference to Climate Change: Fossil Wood Evidences
    Emergence and extinction of Dipterocarpaceae in western India with reference to climate change: Fossil wood evidences Anumeha Shukla∗, RCMehrotraand J S Guleria Birbal Sahni Institute of Palaeobotany, 53 University road, Lucknow 226 007, India. ∗Corresponding author. e-mail: anu [email protected] Climate has played a crucial role in assigning a different kind of topography to Rajasthan and Gujarat since the Cenozoic time. Evidently, three genera, namely, Dipterocarpus Gaert. f., Hopea Roxb. and Shorea Roxb. of the Dipterocarpaceae are described from the Neogene sediments of western India (Rajasthan and Gujarat). These taxa are marked by their complete absence in the region today. The presence of Dipterocarpaceae in western India has been noticed from the Early Eocene up to the Plio- Pleistocene in deep time. The family is usually a dominant component of the humid tropical and subtropical flora of the Indo-Malayan region and its discovery, along with earlier described fossils from western India indicates existence of ancient tropical rain forests in western India. A change in the climate affected warm and humid conditions occurring there during the Cenozoic resulting in arid to semi-arid climate at present which is responsible for the ultimate extinction of Dipterocarpaceae in the region. In addition, the palaeobiogeography of Dipterocarpaceae is reviewed. 1. Introduction understorey.

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.

The tree communities in this ecosystem are dominated by a species-rich family, the Dipterocarpaceae (Ashton, 1982; Proctor et al., 1983; Newman et al., 1996, 1998; Brearley et al., 2004; Slik et al., 2009). This family is one of the most well-known trees in the tropics (Appanah and Turnbull, 1998) and the species are considered to be most important both from the ecological and economic points of view (Lamprecht, 1989). Dipterocarps occur in the lowland forest with up to 80% of the emergent individuals and 40% understorey trees (Ashton, 1982). In the Philippines, they are mostly found in groups with other species occurring in relatively dense stands (Lomibao, 1973). During the past century, however, the Philippine forests were vastly denuded due to logging, fuel wood gathering and charcoal making, shifting cultivation and permanent agriculture (Kummer, 1992; FMB-DENR, 1999). There was a rapid loss of the forests from 21M hectare in 1900 to less than 6M hectares in 1996 (DENR, 2002), a scenario considered to be one of the most severe forest destructions in the world (Heaney, 1998).

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.

    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.

  • 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.
