Diversity and Distribution of Orchids in Selected Sites in Perlis, Peninsular Malaysia

2006 •

Wendy Yong

Perlis is the smallest and northernmost state in Peninsular Malaysia, bordered by Thailand in the north and Kedah in the south. Most of the remaining forested areas in Perlis lie in a continuous belt along the western border. The forests lie mainly on hilly terrain of limestone, which is part of the Setul and Chuping limestone formation. The forest in Perlis is characterized as semi-deciduous forest and influenced by the monsoonal season, floristically unique to Peninsular Malaysia. Thus, Perlis is well-known to have many species unique only to limestone and endemic to the northern part of Peninsular Malaysia and Perlis. However, most of the studies on limestone flora, including Orchidaceae in the northern parts of Peninsular Malaysia were concentrated on Langkawi Islands. Therefore, the diversity and distribution of Orchidaceae in Perlis is still poorly known. In this study, 11 limestone hills and a granite hill in the western part of Perlis have been botanized. The diversity and d...

Preliminary Checklist of Orchids in the Sungai Kangkawat, Imbak Canyon Conservation Area (ICCA), Sabah, Malaysia

Nor Azizun Rusdi

A study on orchids diversity was carried out in the Sungai Kangkawat, Imbak Canyon Conservation Area (ICCA), Sabah, Malaysia. The study aimed to record species composition and distribution of orchids in the furtherance of orchid conservation objective in the gazetted conservation area. A total of 95 species and 30 genera were collected from South Rim, Kawang, and Nepenthes trails. The collection consists of 91 epiphytes, two terrestrials, and two mycoheterotrophs. More orchids were found in the riverine than inland areas. Our study on the species composition based on the vegetation types shows that the presence of inconspicuous and achlorophyllous, either mycoheterotrophic or leafless epiphytic orchids, are indicators of the undisturbed vegetation types. Though the finding was preliminary and brief, our encounter of endemic and rare species underlines the importance of Sungai Kangkawat forest area as an orchid biodiversity hotspot.

The Orchid Flora of Gunung Ledang (Mount Ophir), Malaysia - 120 Years after Ridley

2021 •

Ahmad Sofiman Othman

A comprehensive assessment on the orchid flora of Gunung Ledang, Johor, Malaysia was carried out from 2012 to 2018 with the aim to re-evaluate the presence of orchid species listed by Ridley in his “Journal of the Straits Branch of the Royal Asiatic Society 35:1–28”, published in 1901, after more than 100 years. The relevant account for comparison is also listed, noting that Ridley’s historical collections were for the isolated group of hills commonly known as Gunung Ledang (Mount Ophir), while the collated item in Orchidaceae is part of catalogues for the whole of Peninsular Malaysia. After Ridley, no account on the orchid flora of Gunung Ledang has been properly given, particularly from the uppermost peak of the mountain, where many interesting plants and orchids are to be found there. This study identified 26 species or 67% were the same as those recorded by Ridley (1901), and 65 species or 83% of Turner (1995) checklist of 270 species of orchids for the state of Malacca and Joho...

Building a Motivational Subsystem for the Cognitive Systems Toolkit

2017 •

Eduardo de Moraes Froes

Motivations and emotions are intrinsically embedded in animal cognition and behavior, particularly in humans. They are responsible for supporting decision making, stimulating different behaviors such that their internal needs are satisfied. These needs can be of physiological origin (hunger, thirst, sleep and damage avoidance) or social (friendship, curiosity, honor, etc.). This work proposes the design and implementation of a motivational system endowed with motivational and emotional capacities for the ”Cognitive System Toolkit” (CST), a Java-based software toolkit for cognitive computing being developed by our research group, based on studies of theories on motivational and emotional behavior available in the literature and the different implementations of motivational and emotional systems in known cognitive architectures. Keywords—Motivational System, Goal-directed Behaviors, Motivations, Emotions, Cognitive Architectures, Cognitive System Toolkit (CST).

Sains Malaysiana 41(5)(2012): 505–526 Orchids of Cloud Forest in Genting Highlands, Pahang, Malaysia (Anggerik Hutan Awan Genting Highlands, Pahang, Malaysia) D NG YONG JIN, RUSEA GO*, ROSIMAH NULIT, KHOR HONG ENG, TAN MUI CHING, FARAH ALIA NORDIN, AHMAD AINUDDIN NURUDDIN & LEE NAM SOOK TE ABSTRACT RR EC An inventory of orchid species diversity was carried out in cloud forest of Genting Highlands, which is one of the most developed highland areas in Peninsular Malaysia. Since 1967, construction of roads and hotel complexes has had a serious impact on its physical environment and vegetation. Habitat destructions together with climate change might have caused some orchid species to be extirpated locally or extinct. The cloud forest of Genting Highlands consists of 4 major peaks, Gunung Ulu Kali, Gunung Chin Chin, Gunung Lari Tembakau and Gunung Mengkuang. However, not much study on orchid diversity was conducted in these areas, therefore, this study is timely and essential to evaluate WKHFXUUHQWRUFKLGGLYHUVLW\DIWHUDJDSRIGHFDGHV&RPELQHGÀQGLQJVIURPWKHFXUUHQWVWXG\SUHYLRXVSXEOLVKHG works and specimens deposited in local herbaria, including those at the Universiti Malaya, Universiti Kebangsaan Malaysia, Forest Researh Institute of Malaysia and Biology Department, Faculty of Science, Universiti Putra Malaysia and Singapore Botanic Gardens, an updated list of orchid species found in the cloud forests of Genting Highlands is presented. A total of 134 orchid taxa were recorded, comprises of 51 genera, 132 species, 1 subspecies and 2 varieties, of which 46 are new records to Genting Highlands. Hymenorchis javanica, a species previously reported as endemic to West Jawa was recently discovered in Gunung Ulu Kali.

Through our observations, most of the orchid species in Gunung Ulu Kali are very susceptible to disappearance due to loss of habitat and local climate change. An assessment of conservation status according to IUCN criteria revealed that 47 orchid taxa from Gunung Ulu Kali were threatened with extinction. Conservation actions were suggested to conserve the orchid diversity in the cloud forest region of Genting Highlands.

Walau bagaimanapun, tidak banyak kajian kepelbagaian anggerik telah dijalankan di kawasan ini. Oleh itu kajian ini adalah tepat pada masanya dan penting untuk menilai kepelbagaian anggerik semasa selepas jurang tiga dekad. Gabungan penemuan daripada kajian semasa, kerja sebelumnya yang telah diterbitkan dan spesimen yang disimpan di herbaria, termasuk Universiti Malaya, Universiti Kebangsaan Malaysia, Institut Penyelidikan Perhutanan Malaysia dan Jabatan Biologi, Fakulti Sains, Universiti Putra Malaysia dan Singapore Botanic Gardens, maka senarai terkini spesies anggerik yang ditemui di hutan awan Genting Highlands diperuntukkan. Sejumlah 134 takson anggerik telah dicatatkan, terdiri daripada 51 genus, 132 spesies, 1 subspesies dan 2 varieti, yang mana 46 daripadanya adalah rekod baru untuk Genting Highlands. Hymenorchis javanica, spesies yang dilaporkan sebelum ini sebagai endemik kepada Jawa Barat baru-baru ini ditemui di Gunung Ulu Kali, merupakan rekod baru untuk Malaysia.

It lies within the Titiwangsa Range (Main Range) and is on the Pahang and Selangor border. The summit region of Genting Highlands together comprises of Gunung Ulu Kali, Gunung Chin Chin, Gunung Mengkuang and Gunung Lari Tembakau also Gunung Purun, which is totally replaced by hotels and amusement park complexes, is one of the most disturbed cloud forests in Malaysia. Gunung Ulu Kali with approximately 1770 m above sea level is the highest peak of the summit region. Prior to this study, there were three different published ÁRULVWLFVWXGLHVWKDWGLUHFWO\LQFOXGHGWKLVSDUWRI*HQWLQJ Highlands as locality of their studies (Ridley 1924; Piggott 1977; Stone 1981; Salifah et al. 2009). Stone’s study on the VXPPLWÁRUDRI*XQXQJ8OX.DOLZDVFDUULHGRXWLQ and was published in 1981. In his study, he indicated that the temperature of the summit region of Gunung Ulu Kali ranging from 21-23°C during the day and drop to 10oC at night. The relative humidity may drop below 60% and evaporation rate is high in windy days (Burgess 1969). However metrological data provided by The Resorts World Sdn. Bhd. shows that mean monthly air temperature during 1994-1995 was 19.7°C with a mean annual rainfall of 3534 mm and mean relative humidity of 53.7% (Chua & Saw 2001). Recent data by Kamarulzaman et al. (2009) using Automated HOBO Weather Station installed at Gunung Ulu Kali recorded mean temperature was 16.5°C, mean annual rainfall was 2339 mm, mean relative humidity was 91.3%.

However, Whitmore and Burnham (1969), described the critical range of transitional altitude from lower montane forest to upper montane forest in Genting Highlands is between 4000 ft. (1220 m) to 5400 ft. (1646 m). In the sheltered area of Genting Highlands, the lower montane forest may ascend to 1646 m, while in exposed area the upper montane forest may descend to 1220 m.

Genting Highlands was an undisturbed virgin forest until year 1967, when Lim Goh Tong founded it, and started to develop it into a tourism site well-known as casino, entertainment and hotel complex. Before the establishment of casino and hotel complex, this area could only be reached by trekking through the jungle. The earliest development was a road branching off from Kuala Lumpur – Kuantan trunk road through the Genting Sempah to the summit area which was constructed in 1967 (Piggott 1977; Stone 1981). To date, Genting Highlands has been developed into a most famous tourism site in Malaysia that attracted 19.2 million visitors in 2008. It consisted of six hotels with 10,000 rooms, 170 dining and shopping outlets, golf courts, farms and other facilities as well (Genting Malaysia Berhad 2010). Consequently, the development in Genting Highlands KDVVLJQLÀFDQWO\DIIHFWHGWKHFORXGIRUHVWLQLWVVXPPLW regions. The changes in species composition observed by Chua & Saw (2001), revealed that there have been severe environmental changes at Genting Highlands. They also suggested that the fragmentation of forests may have some negative impacts on certain plant species, while others may not be affected. Salifah et al. (2009) reported that much of Genting Highlands area has loss its original biodiversity due to human activities as 80.5% of pteridophytes recorded by Piggott (1977) were not found in their in their study.  $VIRURUFKLGÁRUD6WRQH  UHFRUGHGRUFKLG species comprises of 23 genera. However, there was no other comprehensive study on the orchid diversity of Genting Highlands for nearly 30 years after Stone’s inventory. Undoubtfully, there were some factors that may affect the orchid diversity: (1) forest clearance for development, (2) local climate change, and (3) illegal collection of valuable orchids. The continuous destruction of natural environment in this area coupled with the knowledge of high orchid diversity has enticed us to pursue this diversity study. The changes brought about by human activities and nature have been the key factors that create the urgency to inventory the orchid species in Genting Highlands and to evaluate their conservation status. This paper aimed to address two aspects, information on diversity and distribution of orchids and issues of natural habitat conservation and climate change. D INTRODUCTION MATERIALS AND METHODS Orchid specimens were collected randomly from cloud forest habitat of Genting Highlands throughout the year of 2009. The sampling sites include summit regions of Gunung Ulu Kali, Gunung Chin Chin, Gunung Lari Tembakau, Gunung Purun and Gunung Mengkuang. Orchid specimens collected were preserved using standard herbarium method of Bridson and Forman (1992), then 507 TE EC RESULTS AND DISCUSSION science, similar to the plant found in North Sumatra at 915 m a.s.l. suspected new by Comber (2001). However, he did not further describe nor publishe the new species. Two species were found not only new to Genting Highlands but also to Peninsular Malaysia, Dendrobium sociale and Hymenorchis javanica. Dendrobium sociale was previously only recorded from Sumatera, Thailand and Vietnam (Govaerts et al. 2006). Hymenorchis javanica was claimed to be endemic to West Java (Comber 1990; Govaerts et al. 2008) and now it is also found in Genting Highlands. Most of the new records of orchids found in Genting Highlands are only in a few small populations. Hymenorchis javanicaIRUH[DPSOHLVFRQÀQHGWRDVLQJOH population on a few trees and Paphiopedilum lowii was recorded only with 2 small clumps, which are now totally missing from the location we spotted them then, as the spot is now part of the road expansion. No other plants were recorded, indicating rarity and vulnerability to local extinction with the current rate of forest conversion and environmental changes. Endemism is known to be very high in highland habitats especially in the cloud forest region with altitude 1000 – 3000 m a.s.l. (Raxworthy et al. 2008), D deposited in Herbarium of Biology Department, Faculty of Science, Universiti Putra Malaysia (UPM). Flowers were kept in Copenhagen solution as spirit collection. For species identification, references used including Ridley (1924), Holttum (1964), Teo (1985), Seidenfaden (1992), Comber (1990 & 2001), Turner (1995), Rusea and Khali-Aziz (2008), Rusea et al. (2009) and Rusea et al. (2010). The names used here are according to the World Checklists of Selected Plant Families access online (Govaerts et al. 2008). Specimens in the local herbaria, Herbarium Universiti Kebangsaan Malaysia, Bangi (UKMB), Herbarium of Universiti Malaya (KLU), Herbarium Forest Research Institute of Malaysia (KEP), Herbarium of Biology Department, Universiti Putra Malaysia (UPM) and herbarium abroad, Herbarium of Singapore Botanic Gardens (SING) were also studied for LGHQWLW\YHULÀFDWLRQV A total of 134 orchid taxa were recorded, from 51 genera of which 46 are new records to Genting Highlands (Table 1).

The high number of new records found during this study was expected considering the 30 years gap between current and previous study (Stone 1981). In the past 30 years, the robust development together with global climate change could change the species composition. Some species will be lost due to unfavourable growth environment and some others were newly established and ÁRXULVKHGZLWKFKDQJHVRIFOLPDWLFHOHPHQWV$QRWKHU possibility was that some of the species were overlooked RUPLVVLGHQWLÀHGGXULQJWKHHDUOLHUVWXG\ Seven species (Appendicula uncata, Dendrobium crumenatum, Dendrobium heterocarpum, Dendrobium pahangense, Dendrobium rupicolum, Dendrobium sociale, Pholidota longibulba) are among the new records found 513 D area of Genting Highlands. This evidence supported our hypothesis that temperature rise due to global climate change also impacted the local environment that creates a favorable condition for lowland species to flourish. Species are able to migrate to higher elevation with higher temperature, where they are usually found in open areas of Genting Highlands. These open areas have temperatures 2-3°C higher than under forest canopy thus favorable for the lowland species growth. Some of the newly recorded species are shown in Plate 1. Most of the species recorded in previous study were without specimen cited as they are from published literatures and books. A complete specimen cited information are list in the Appendix.

In a nutshell, Genting Highlands’s summit region is still favourable for orchid growth. However, threats from the changing environment could further enhance pressure to slow adapting species that might cause local extinction. It would be a great loss if some of these species extinct before they are even known and appreciated. Therefore, the inventory of species in this type of vegetation is very important for other parts of Malaysia. The destruction of forested areas is a continuous process in Peninsular Malaysia and that GHÀQLWHO\ZLOOFDXVHVSHFLHVORVV7RSUHYHQWWKLVGLVDVWHU awareness among the public on biodiversity conservation is very important. As for Genting Highlands, the Genting Malaysia Berhad should actively involve with effort towards conserving biodiversity in this region not only for the country but also for their livelihood.
