Vatica mangachapoi is a tree up to 20 m tall with white resinous. It is distributed in China (Hainan province), Indonesia, Malaysia (N Borneo), Philippines, Thailand, and Vietnam. It grows in forests on hills and mountain slopes below 700 metres. Its durable wood is used for making boats and building bridges and houses. It has been ranked as a VU (Vulnerable) species in China. Here we report and characterize the complete plastid genome sequence of V. mangachapoi in an effort to provide genomic resources useful for promoting its conservation and phylogenetic research. The complete plastome is 151,538 bp in length and contains the typical structure and gene content of angiosperm plastome, including two Inverted Repeat (IR) regions of 23,921 bp, a Large Single-Copy (LSC) region of 83,587 bp and a Small Single-Copy (SSC) region of 20,109 bp. The plastome contains 114 genes, consisting of 80 unique protein-coding genes, 30 unique tRNA gene, and 4 unique rRNA genes. The overall A/T content in the plastome of V. mangachapoi is 62.80%. The phylogenetic analysis indicated that V. mangachapoi and V. odorata is closely related and as an independent branch in Malvales in our study. The complete plastome sequence of V. mangachapoi will provide a useful resource for the conservation genetics of this species and for the phylogenetic studies for Vatica.
For over 2 decades, until the economic crisis in mid-1997, Malaysia's rapid economic growth attracted an influx of foreign labor, mostly from Indonesia, Bangladesh, and the Philippines. In 1997 the number of registered workers was estimated at 1.2 million and undocumented ones at approximately 800,000. The influx created various problems, of which housing is one of the most serious, especially in the Kelang Valley. This paper examines the ways and means by which Indonesian workers, the largest group among foreigners, overcame their accommodation problem. Two types of settlements are identified, that is, illegal ones in the squatter areas and legal ones, which are largely in Malay Reservation Areas. The settlements, which signify Indonesians' success in finding a foothold in Malaysia, today have become a base for more in-migration.
Studies of the siamang (Hylobates syndactylus continentis) and the lar gibbon (Hylobates lar lar) where they co-occur in mainland Asia have demonstrated interspecific dietary segregation based on body size and have suggested that observed levels of frugivory represent metabolically based maxima for these species. I studied sympatric groups of siamang (H. s. syndactylus) and lar gibbons (H. l. vestitus) at Ketambe in northern Sumatra (Indonesia) in order to assess the magnitude of within- and between-species variation in diets. The insular subspecies are considerably more frugivorous (60-70% of feeding time) than mainland conspecifics (35-50%). This is primarily because Sumatran hylobatids spend about twice as much time (approx. 45% of feeding) eating fig fruits (Ficus spp., Moraceae). A higher density of figs at Ketambe (compared to Kuala Lompat) may account for this behavioral difference. Enhanced frugivory has been achieved at the expense of folivory, which is much reduced in Sumatra--especially in H. lar (4% of diet)- and is limited almost entirely to immature foliage. The expected decline in protein intake resulting from diminished folivory in Sumatra may be counterbalanced by observed increases in insectivory, which is especially pronounced in lar gibbons. Interspecific dietary segregation emerges most clearly in how individuals of each species supplement their similarly fig-dominated diets. Siamang rely more on immature foliage--primarily from lianas, which generate young leaves more reliably and abundantly than trees do. Conversely, lar gibbons exploit the pulpy fruit of trees and lianas more heavily than siamang do. This general pattern occurs where the two species coexist in Malaysia, thereby suggesting a substantive interspecific difference that is somewhat greater in the insular populations.
"The main purpose here is to provide an overview of the social security arrangements in selected Southeast Asian countries. Given the significant differences in these countries in the underlying philosophy, design and detailed provisions concerning social security arrangements, a country-by-country rather than a comparative approach is adopted." The countries analyzed are Indonesia, Malaysia, the Philippines, Singapore, and Thailand.
Two new nematodes belonging to the subfamily Nippostrongylinae (Nematoda: Trichostrongyloidea: Heligmonellidae) are described based on specimens from endemic murines of Sulawesi, Indonesia: Hasanuddinia maxomyos n. gen., n. sp. from Maxomys musschenbroekii and Eropeplus canus, and Heligmonoides musseri n. sp. from M. musschenbroekii, E. canus, and Margaretamys elegans. Hasanuddinia is closest to Rattusstrongylus of Malaysian rats in lacking a carene and in having a lateromedian gradient in the size of the synlophe ridges in the ventral side of the midbody but is distinguished in that the dorsal ray is divided in the distal half. Heligmonoides musseri most resembles H. bulbosus of Maxomys whiteheadi of Malaysia in having a carene supported by slender ridges of which the proximal portion is not thickened but is distinguished in having longer externodorsal rays and longer spicules. The ancestors of the present Sulawesi nematodes seem to have originated on the southeast Asian continent, were introduced to Sulawesi with the dispersal of some murines, and subsequently speciated.
Following the discovery of mosquito transmission of malaria, the theory and practice of malaria control by general and selective removal of specific vector populations resulted particularly from Malcolm Watson's empirical work in peninsular Malaysia, first in the urban and peri-urban areas of Klang and Port Swettenham and subsequently in the rural rubber plantations, and from the work of N.H. Swellengrebel in nearby Indonesia on the taxonomy, ecology and control of anophelines. They developed the concept of species sanitation: the selective modification of the environment to render a particular anopheline of no importance as a vector in a particular situation. The lack of progress along these lines in India at that time is contrasted with that in south-east Asia. The extension of species sanitation and related concepts to other geographical areas and to other vector-borne disease situations is outlined.
Structured epidemiological studies based on sentinel herds in Indonesia and Malaysia have provided much information regarding the bluetongue (BT) viruses (BTV) and their likely vectors in South-East Asia. Serotypes 1, 2, 3, 7, 9, 12, 16, 21 and 23 have been isolated. Molecular analyses show all group within the Australasian topotype, with four genotypic sub-groupings identified to date. There are relationships to isolates from both India and Australia. Strains of BTV in South-East Asia do not appear to be highly virulent, since BT disease is not seen in local sheep. Known vector species identified include Culicoides fulvus, C. actoni, C. wadai and C. brevitarsis. C. imicola has not been identified in Malaysian or Indonesian studies. Molecular analyses indicate movement of South-East Asian strains of BTV into northern Australia, and the gradation in observations between India and eastern Australia regarding serotype, genotype, virulence and vector species suggests movement along a conceptual gradient through South-East Asia.
This study is based on a survey conducted in Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore, Sri Lanka and Thailand on occupational injuries during the years 1975-1980. The number of work accidents have risen rapidly during this period in all of the 8 countries studied. In the case of Thailand, the total number of work injuries increased four fold from 1975-1978, whereas, in Singapore it has almost doubled in 6 years. The number of permanent disablement nearly trebled in Korea, and the Philippines for the year 1967-1980. The largest percentage of accidents are lost-time injuries in all of the 8 countries. Thailand had a three fold increase in lost-time injuries whilst in Hong Kong the figure doubled. Six out of the 8 countries indicated that the building construction industry had the largest number of fatal accidents, followed by the manufacturing industry.
Latah is a culture-bound syndrome from Malaysia and Indonesia. Persons exhibiting the Latah syndrome respond to minimal stimuli with exaggerated startles, often exclaimning normally inhibited sexually denotative words. Sometimes Latahs after being startled obey the commands or imitate the actions of persons about them. Most episodes of Latah are intentionally provoked for the amusement of onlookers. Similar sets of interactive behaviors have been reported from genetically and culturally unrelated populations (e.g., Bantu, Ainu, and French Canadians). Since competent anthropological investigators have shown Latah to be intimately tied to specific factors in the cultural systems of the Southeast Asian societies in which it is found, its occurrence elswhere has been considered paradoxical. New data, including films and videotapes of hyperstartling persons from Malaysia, the Philippines, Japan, and the United States, suggest a model capable of resolving the apparent paradox by showing how the various forms of latah are culture-specific exploitations of a neurophysiological potential shared by humans and other mammals. Latah provides an especially revealing example of the complex ways in which neurophysiological, experiential, and cultural variables interact to produce a strongly marked and phenomenon.
Haemaphysalis (Garnhamphysalis) mjoebergi Warburton was reported from four male specimens from Sarawak, Borneo. We redescribe herein the male, from three specimens from Sarawak and 24 from Lampung District, Sumatra, and describe the female from 24 specimens from Lampung. Male structural variation in the dental formula and development of the coxa IV spur and segments of legs III and IV is unusual or unique in the genus Haemaphysalis. "Atypical" males might easily be misidentified. This species provides an ideal model for experimental study of population genetics and evolutionary processes and of biological factors influencing body size and structural variation in the genus Haemaphysalis. The sambar deer, Cervus unicolor brookei Hose (Sarawak) and C. unicolor equinus Cuvier (Sumatra), appears to be the chief host in humid, marshy, lowland forests and secondary growth. Single collections were from a human and a domestic cow. The dynamics and vector potential of this tick should be investigated in environments being exploited for human settlement and cattle breeding.
DDT indoor residual sprayings in the Province of Central Java, Indonesia, for the past 28 years are reoieuied in terms ofAnopheles aconitus resistance to DDT and incidences of malaria. DDT resistance by An. aconitus has continued to increase and spread since its first detection in Central Java in 1962. In most areas malaria transmission is perennial, which appears to be not interrupted by DDT residual spraying of inner walls because of DDT resistance. In searching for alternatives to DDT, fenitrothion was the most effective residual compound among five insecticides tested in village scale trials, giving control for about 13 weeks at 2 g/m2. Because the target species rests largely on the lower portions of walls, when applied at 2 g/m2 to only one horizontal swath between 10 and 85 cm from the ground, this compound was effective for over two months, about one-third less than that found in full coverage applications. For a single application this selective method reduced the amount of insecticide by 65 percent and manpower by 43 percent, and three applications, to compensate for less residual effectiveness, will reduce insecticide use by about 50 percent and manpower by 15 percent, compared to two applications with full coverage. Further field investigations on application of insecticides and the ecology of the DDT-resistant vector continue to be needed in Central Java to reduce further the cost of residual sprayings in malaria control programmes. This review also suggests the possibility of other selective spraying methods and anti-vector methods applicable at the village level by the community.
The Clitoria ternatea (Fabaceae) root, seed, and leaf are commonly used in Ayurvedic medicine in Malaysia and Indonesia. The methanol leaf extracts of C. ternatea was tested for toxicity by means of brine shrimp lethality test and acute oral toxicity assay. In the brine shrimp lethality test, the leaf extract were non-toxic or showed weak lethality (LC50 > 1 mg/ml) at the 6 h, 12 h and 24 h incubation period. Nevertheless, at the 48 h incubation time, the leaf extract exhibited moderate toxicity activity with LC50 values of 0.49 mg/ml. In the acute toxicity study using mice, the median lethal dose (LD50) of the extract was found greater than 2000 mg/kg, and we found no pathological changes by means of macroscopic examination of tissues of mice treated with the extract. We conclude that the C. ternatea leaf extract is not toxic in mice and brine shrimp.
Marination directly affects the texture and flavor of meat and is important for product yield. This research investigated the effects of various marinating solutions on the physicochemical, microstructural and sensory properties of golek chicken, a popular dish in Malaysia, Indonesia and southern Thailand. Non-marinated meat (Tr1-control) was compared with five marinating treatments: distilled water (Tr2); sodium chloride (Tr3); a mixture of sodium chloride and sodium tripolyphosphate (STPP) (Tr4); a mixture of sodium chloride, STPP and citric acid (Tr5); and a mixture of sodium chloride, STPP and sodium bicarbonate (Tr6). Marinating meat in Tr3–Tr6 resulted in higher water-holding capacity and cooking yield, as well as lower shear force value and cooking loss, when compared to Tr1 and Tr2 (p
