Hypothesis The usage of GLCM features as a computational approach Abstract - This paper briefly describes two methods used to to identify Hopea sangal, Shorea pauciflora, Anisoptera differentiate leaves of five species, Anisoptera megistocarpa, Dipterocarpus grandiflorus and Vatica megistocarpa, Dipterocarpus grandiflorus, Hopea sangal, maingayi achieves a higher accuracy than the usage of a Shorea pauciflora and Vatica maingayi, that belong to the dichotomous key. Dipterocarpaceae family. The two methods are: a) the traditional approach, namely, a dichotomous key and b) the 3. Method and materials computational method which consists of the use of Gray Level Co-occurrence Matrix (GLCM). Through the two approaches, we then compare the accuracy rates in identifying the leaf species by running tests using both methods. GLCM achieved an overall identification accuracy of 93.3%, while the dichotomous key achieved an average Fig 1. Overview of methodology accuracy rate of 85%. 3.1. Species selection and Data collection The sample species were selected based on three criteria, Keywords: dichotomous key, Gray Level Co-occurrence using the Checklist of Total Vascular Flora of Singapore. Matrix The first criterion is the native status of each species. All the chosen species are locally cultivated so that educators and amateur botanists would be able to identify the trees they 1.

The study aimed to document plant diversity and to identify interesting, endemic, rare and threatened plant species which were considered high conservation value species. A total of 413 species from 82 families were recorded from the study area of which 93 taxa were endemic to Borneo, including 10 endemic to Sabah. These high conservation value species are key conservation targets for any forested area such as ICCA. Proper knowledge of plant diversity and their conservation status is vital for the formulation of a forest management plan for the Batu Timbang area. Keywords: Vascular plant, floral diversity, endemic, endangered, Borneo Introduction The earth as it is today has a lot of important yet beneficial natural resources such as tropical forests. Tropical forests are one of the world’s richest ecosystems, providing a wide range of important natural resources comprising vital biotic and abiotic components (Darus, 1982). -

A Review of Animal-Mediated Seed Dispersal of Palms
Selbyana 11: 6-21 A REVIEW OF ANIMAL-MEDIATED SEED DISPERSAL OF PALMS SCOTT ZoNA Rancho Santa Ana Botanic Garden, 1500 North College Avenue, Claremont, California 91711 ANDREW HENDERSON New York Botanical Garden, Bronx, New York 10458 ABSTRACT. Zoochory is a common mode of dispersal in the Arecaceae (palmae), although little is known about how dispersal has influenced the distributions of most palms. A survey of the literature reveals that many kinds of animals feed on palm fruits and disperse palm seeds. These animals include birds, bats, non-flying mammals, reptiles, insects, and fish. Many morphological features of palm infructescences and fruits (e.g., size, accessibility, bony endocarp) have an influence on the animals which exploit palms, although the nature of this influence is poorly understood. Both obligate and opportunistic frugivores are capable of dispersing seeds. There is little evidence for obligate plant-animaI mutualisms in palm seed dispersal ecology. In spite of a considerable body ofliterature on interactions, an overview is presented here ofthe seed dispersal (Guppy, 1906; Ridley, 1930; van diverse assemblages of animals which feed on der Pijl, 1982), the specifics ofzoochory (animal palm fruits along with a brief examination of the mediated seed dispersal) in regard to the palm role fruit and/or infructescence morphology may family have been largely ignored (Uhl & Drans play in dispersal and subsequent distributions. field, 1987). Only Beccari (1877) addressed palm seed dispersal specifically; he concluded that few METHODS animals eat palm fruits although the fruits appear adapted to seed dispersal by animals. Dransfield Data for fruit consumption and seed dispersal (198lb) has concluded that palms, in general, were taken from personal observations and the have a low dispersal ability, while Janzen and literature, much of it not primarily concerned Martin (1982) have considered some palms to with palm seed dispersal. -

In Cambodia, 18 species have been recorded so far and most of them are daily used by local communities and supplying the rattan industry. Meanwhile, with rattan resources decreasing due to over-harvesting and loss of forest ecosystem there is an urgent need to stop this trend and find ways to conserve this biodiversity that play an important economic role for the country. This manual is one step towards sustainable rattan management as it allows to show/display the diversity of rattan and its contribution. -

Maintenance and conservation of Dipterocarp diversity in tropical forests _______________________________________________ Mohammad Nazrin B Abdul Malik A thesis submitted in partial fulfilment of the degree of Doctor of Philosophy Faculty of Science Department of Animal and Plant Sciences November 2019 1 i Thesis abstract Many theories and hypotheses have been developed to explain the maintenance of diversity in plant communities, particularly in hyperdiverse tropical forests. Maintenance of the composition and diversity of tropical forests is vital, especially species of high commercial value. I focus on the high value dipterocarp timber species of Malaysia and Borneo as these have been extensive logged owing to increased demands from global timber trade. In this thesis, I explore the drivers of diversity of this group, as well as the determinants of global abundance, conservation and timber value. The most widely supported hypothesis for explaining tropical diversity is the Janzen Connell hypothesis. I experimentally tested the key elements of this, namely density and distance dependence, in two dipterocarp species. The results showed that different species exhibited different density and distance dependence effects. To further test the strength of this hypothesis, I conducted a meta-analysis combining multiple studies across tropical and temperate study sites, and with many species tested. It revealed significant support for the Janzen- Connell predictions in terms of distance and density dependence. Using a phylogenetic comparative approach, I highlight how environmental adaptation affects dipterocarp distribution, and the relationships of plant traits with ecological factors and conservation status. This analysis showed that environmental and ecological factors are related to plant traits and highlights the need for dipterocarp conservation priorities. -
