Natural Barriers

A global geographic fragmentation has caused the diversity of animals and plants worldwide, mostly to the population of small mammals. In Malaysia, there are a lot of natural barriers that can separate the population of small mammals including common treeshrew, Tupaia glis. In this study, the polymorphism of ninety (90) Tupaia glis in Peninsular Malaysia is carried out by comparing the skulls of the species from different states by using MorphoJ analysis. This is carried out to know the landmark of the species and the shape changes.

Tupaia Glis

Recent morphometric analysis on T. glis in Peninsular Malaysia indicates that there were more than one morphotypes in this species. Thus this study attempts to examine this phenomenon using mitochondrial DNA sequences of Cyt b and CO1 genes. A total of 74 DNA sequences for both genes were generated using available universal primers. Samples from Southern Thailand were found to be misidentified as T. glis when in fact these samples clustered with T. belangeri while one T. tana from Borneo was miss-identified as T. minor. The phylogenetic trees showed that there are at least one confirmed morphotype of Tupaia (new Tupaia sp.) that have yet to be described. The results also showed that the separation of T. glis morphotype 1 and 11 were visible in the combined genes tree, congruent with the morphometric phylogeny but had poor phylogenetic support.

Selection Of

The uniqueness of the Malay heritage house architecture lies in the diversity of carving forms of various motifs. The motif was chosen based on the image of the environment at the time. This paper discusses the selection of carving motifs in Malay houses based on the principle of form follows function introduced by a Western architect Louis Sullivan in the late 19th century. The meaning of form follows function in this study refers to the selection of the shape of a carving motif adjusted according to the function of the space in the Malay heritage house. A preliminary study was conducted on 10 Malay heritage houses in Peninsular Malaysia built in the 1800s. It aimed to get the types of commonly used motifs during the century of the principle was introduced. The selected houses were located in 10 states in Peninsular Malaysia obtained from measured drawings from the Center for the Study of Built Environment in The Malay World (KALAM) in Universiti Teknologi Malaysia (UTM). The selected houses were based on the most widely used carving motifs. For the purpose of this study, three houses were selected from the initial 10 houses to be further analyzed and mapped in terms of shape and placement of carving motifs based on the principle of form follows function. The study focused on the carving motifs in serambi and rumah ibu of the Malay heritage house as these two spaces had the most carving motifs. The mapping of the motifs in the two spaces shows four main motifs of flora, fauna, geometry, and calligraphy. The motifs of each home will be described from the angle of symbolism, layout, and carving style that can describe the principle of form follows function

The mangrove forest is located in the coastal intertidal zone and plays a vital role in buffering against erosion from storm surges, currents, waves, and tides. This ecosystem also serves for ecotourism due to its heterogeneous habitats, which supported a high diversity of plants and animals. Small mammals are among the abundant but poorly recognised inhabitants in mangrove forests. Apart from their role as primary consumer and prey, they are host to various ectoparasites, which potentially become the primary vector for tick-borne diseases among visitors. Therefore, this study aims to determine the small mammal assemblages and their ectoparasite prevalence in mangroves forests of Peninsular Malaysia. The capture-release method was applied for small mammal sampling, and each captured individual was screened and collected for ectoparasites before released. DNA barcoding using CO1 genes was performed for small mammal species verification, whereby ectoparasite identification was based on morphological identification and molecular verification using 16S rDNA genes. A total of 94 small mammals from 6 species were captured across sites, dominated by Rattus tiomanicus (n=74). From this number, 15 individuals (16% prevalence) were infested by ticks, 22 individuals (23%) were infested by mites, whereas 4 individuals (4%) were infested by both ticks and mites. Five species of ticks and one mite species were identified; Amblyomma cordiferum, Ixodes granulatus, Haemaphysalis hystricis, Dermacentor auratus, Dermacentor atrosignatus, and Laelaps echidninus. This study reveals a relatively poor diversity of small mammals in the mangroves forest, of which highly infested with a diversity of ectoparasites, elucidating the relationship of hostectoparasite associations in the riparian zone. This information is crucial to inform visitors to these areas, ultimately safeguard against ectoparasite-borne disease.
