Earthen–wooden hybrid houses built by the Dai in Dehong Prefecture, South China

The Dai (or Tai) are an indigenous ethnic group distributed across the upper part of Southeast Asia and South China. Whereas the majority of the Dai living on the Southeast Asian mainland build wooden houses on stilts, Dai populations in South China, especially in Dehong Prefecture, are known for the distinctive architectural style of their hybrid earthen–wooden houses, which stems from their enduring social contact and cultural assimilation with Chinese settlers. This paper, which draws on comprehensive fieldwork conducted in Dai villages in Dehong Prefecture, explores the Dai’s hybrid earthen–wooden architecture. Specifically, it examines the development of forms, the relationship between settlement layouts and house plans, as well as building materials, structures and constructions characterising this architecture using data from qualitative surveys, architectural measurements and interviews. The hybrid architecture of the Dehong Dai demonstrates the fusion of two building cultures—earthen and wooden—that has shaped a vernacular architectural identity that is unique to this area. This paper also presents illustrative examples of earthen–wooden houses, thereby contributing to advancing knowledge about this eclectic, hybrid architecture that remains a gap in the academic literature.

Suitable Habitat Modeling of Prehistoric Antelope-like Bovid Duboisia Santeng in Java Island in The Early Pleistocene

The migration routes have facilitated the distribution of mammals from south east Asian mainland to the Sundaland including Java island in the early Pleistocene. One of species that has migrated through that route is antelope-like bovid Duboisia santeng. In the present study, the potential distribution areas and the suitable habitats of D. santeng have been projected and modeled. The modeled habitat was a forest river basin sizing 302.91 Ha in the central of Java island. The model has classified and reconstructed the habitat suitability ranged from low to high back to Pleistocene. The surrounding areas of forest were mostly classified as medium and low related to the limited tree covers. Most suitable habitats were identified in the middle of forest river basin where the tree covers were presented

Impact of the Mid-Pleistocene Revolution and Anthropogenic Factors on the Dispersion of Asian Black-Spined Toads (Duttaphrynus melanostictus)

Divergence-time estimation critically improves the understanding of biogeography processes underlying the distribution of species, especially when fossil data is not available. We hypothesise that the Asian black-spined toad, Duttaphrynus melanostictus, expanded into the Eastern Indomalaya following the Quaternary glaciations with the subsequent colonisation of new landscapes during the Last Glacial Maximum. Divergence dating inferred from 364 sequences of mitochondrial tRNAGly ND3 supported the emergence of a common ancestor to the three D. melanostictus clades around 1.85 (±0.77) Ma, matching with the Lower to Mid-Pleistocene transition. Duttaphrynus melanostictus then dispersed into Southeast Asia from the central Indo-Pacific and became isolated in the Southern Sundaic and Wallacea regions 1.43 (±0.10) Ma through vicariance as a result of sea level oscillations. The clade on the Southeast Asian mainland then colonised the peninsula from Myanmar to Vietnam and expanded towards Southeastern China at the end of the Mid-Pleistocene Revolution 0.84 (±0.32) Ma. Population dynamics further highlight an expansion of the Southeast Asian mainland population towards Taiwan, the Northeastern edge of the species’ range after the last interglacial, and during the emergence of the Holocene human settlements around 7000 BP. Thus, the current divergence of D. melanostictus into three segregated clades was mostly shaped by Quaternary glaciations, followed by natural dispersion events over land bridges and accelerated by anthropogenic activities.

From mainland to islands: colonization history in the tree frog Kurixalus (Anura: Rhacophoridae)

The origin and colonization history of Kurixalus, a genus of small arboreal tree frogs breeding exclusively in shallow swamps, is under disputed. On the basis of comprehensive sampling program, the evolutionary history of Kurixalus is investigated based on 3 mitochondrial genes. Our results indicate that the genus Kurixalus originated in the Asian mainland and subsequently arrived at its current distribution in Borneo, Taiwan, Ryukyu, and Hainan islands by a series of dispersal events. Moreover, the colonization of Taiwan from mainland Asia has occurred 2 times. The initial colonization of Taiwan occurred at 3.46–8.68 Mya (95% highest posterior density), which rejects the hypothesis that Kurixalus probably originated from Taiwan during the early Oligocene and favors the model of Neogene-origin rather than the model of Quaternary-origin for Taiwanese Kurixalus. Kurixalus eiffingeri has dispersed from Taiwan to the Ryukyus once or 2 times pending more data. Both transoceanic dispersal and landbridge dispersal have played a role in the colonization process; the former resulted in the colonization of Taiwan and the Ryukyus and the latter led to the colonization of Borneo and Hainan.

The Collapse of Pergamon

Pharnakes was succeeded by his brother Mithridates IV in the early 150s BC. His reign was brief, and his son, the powerful Mithridates V, became king within a decade. Mithridates V ruled for thirty years; during his reign the important state of Pergamon, to the west of Pontos, came to an end with its territory willed to the Roman Republic. This gave Rome territory on the Asian mainland. At first Pontic policy was to support Roman ambitions: Mithridates V sent aid to them in their third war against Carthage. His international posture was recognized by the island state of Delos and elsewhere in the traditional Greek world. But around 120 BC he was assassinated at Sinope on the Black Sea, which had replaced Amaseia as the Pontic capital; he was the only Pontic king to suffer such a fate.

On the Origins of the Japanese Language

In this article, I deal with the historical development of the Japanese language by applying a multi-disciplinary approach that uses data from a variety of fields. My research indicates that the home-land of the Japonic language family may have been in the lower Yangtze River Valley, from where its speakers moved to the Korean Peninsula and eventually to Japan during the Yayoi period. This spread is associated with the dispersal of wet rice agriculture from the area south of the Yangtze River via the northeastern Asian mainland, where it was in contact with cultures cultivating millet. Old Japanese mythology and genealogical data suggests that the earliest known ethnic group that spoke Japonic may have been the Hayato people of southern Kyūshū.1

Notes on Mucuna (Leguminosae: Papilionoideae) in Thailand: fruits of M. oligoplax re-assessed, and a revised key to species with lamellate fruits

Summary Fruiting material of a Mucuna from Peninsular Thailand with distinctive lamellae proved to be conspecific with M. oligoplax, which was previously thought to have fruit almost lacking lamellae. A revised description and a distribution map for M. oligoplax are presented. This finding also necessitates revision of the key to Mucuna species from the Asian mainland with lamellate pods.

The Malay Language in Mainland Southeast Asia

Today the Malay language is known to have communities of speakers outside the Malay archipelago, such as in Australia inclusive of the Christmas Islands and the Cocos (Keeling) Islands in the Indian Ocean (Asmah, 2008), the Holy Land of Mecca and Medina (Asmah et al. 2015), England, the Netherlands, France, and Germany. The Malay language is also known to have its presence on the Asian mainland, i.e. Thailand, Cambodia, and Vietnam. As Malays in these three countries belong to a minority, in fact among the smallest of the minorities, questions that arise are those that pertain to: (i) their history of settlement in the localities where they are now; (ii) the position of Malay in the context of the language policy of their country; and (iii) maintenance and shift of the ancestral and adopted languages.
