The dorsalis complex contains some of the most economically important fruit fly pests of the Asia–Pacific regions, including Bactrocera dorsalis, Bactrocera papayae and Bactrocera carambolae. These species are morphologically indistinct and genetically very similar. We describe the development of 12 microsatellite markers isolated from a representative of the dorsalis complex, B. papayae. We show the potential utility of the B. papayae microsatellites and a set of microsatellites isolated from Bactrocera tryoni as population and species markers for the dorsalis complex. 相似文献

Riverside vegetation dominated by Salix gracilistyla was analysed. In total, 77 phytocoenological relevés from Japan and both Korean Republics were compared. Based on 20 own
relevés from Kumgang-san Mts (North Korea) a new association Artemisio feddei-Salicetum gracilistylae was described. It occupies alluvia of rivers and streams flooded for several times yearly. This species-rich community differs
from the most similar, but species-poor association Salicetum gracilistylae Minamikawa 1963, described from Japan and known also from South Korea by numerous differential taxa. 相似文献

The evolutionary history and taxonomic reevaluation of the Japanese coral snake,Sinomicrurus japonicus (Serpentes,Elapidae), endemic to the Ryukyu Archipelago,Japan, by use of molecular and morphological analyses 下载免费PDF全文
Takuma Kaito Hidetoshi Ota Mamoru Toda 《Journal of Zoological Systematics and Evolutionary Research》2017,55(2):156-166
Sinomicrurus japonicus has a conspicuous colour pattern of longitudinal black stripes and transverse sets of black and white bands with an orange‐reddish background colour. The pattern varies markedly among island populations, and thus, three subspecies have been recognized. We conducted molecular phylogenetic analyses on the island populations to clarify the evolutionary trajectory of such colour patterns and reevaluate the current classification accordingly. The results indicated relatively deep allopatric divergences within S. j. boettgeri, paraphyly of S. j. boettgeri against other two subspecies, and two independent derivations of S. j. takarai from boettgeri‐like ancestors. Detailed morphological analyses revealed that variations in the boettgeri and takarai forms were more or less continuous and that differences between the two takarai populations were very small. From these results, we propose synonymizing S. j. takarai with S. j. boettgeri. Morphological differences between the genetically most distant populations of S. j. boettgeri were also small, whereas the japonicus form was distinct from the remainder. Considering the possible evolution of S. j. japonicus through peripheral isolation, we propose retention of these two subspecies. This study provides a basis for future work on the adaptive significance of geographic variation in the colour pattern of S. japonicus. 相似文献

Throughout continental Southeast Asia, the Hoabinhian techno-complex stands out in clear contrast with the universal chrono-cultural model essentially established on the basis of western prehistory. Following this model, early authors considered perforated stones and associated lithic artefacts as markers of what was then believed to pertain to a Southeast Asian Mesolithic. However, Southeast Asian Mesolitithic has progressively been abandoned in favour of a ubiquitous Hoabinhian spanning from 30,000 to 3000 BP. Here, we present and discuss the discovery of perforated stones at the Doi Pha Kan site in northern Thailand. Perforated stones have almost never been found in undisturbed stratigraphic conditions nor dated with any sufficient degree of certainty. At Doi Pha Kan site, such a kind of artefacts was found in burials intersecting sedimentary layers that could be ascertained as Hoabinhian. In contrast with similar perforated stones described in the literature, that found at Doi Pha Kan are well-dated (13,000 BP), thus providing a time-reference for a putative Southeast Asian Mesolithic. We therefore advocate that such non-Hoabinhian artefacts support the early authors’ hypothesis of the existence of a Southeast Asian Mesolithic. Finally, the funerary practices, the unusually high stature of individuals found at Doi Pha Kan in conjunction with the particular lithic assemblages further contributes to raise the question of the co-occurrence of several cultures or populations at the Pleistocene–Holocene interface in continental Southeast Asia. 相似文献

Jural relations of middle‐class marriage and women as legal subjects in the imaginary of ‘new India’ 下载免费PDF全文
Shalini Grover 《The Australian journal of anthropology》2017,28(3):251-268
In India's capital New Delhi, four Family Courts were set up between 2009 and 2012, and 12 mediation institutions known as Crime Against Women Cells (CAW cells) were established during the same period. The Indian state has also endorsed gender‐equalising family legislation, mutual‐consent divorce and introduced new language of and for mediation. Together with India's projection of a rising global economy, these recent legal changes have engendered perceptions of a dramatic upturn in formal divorce and of women as liberal legal subjects. In the anthropology of Asia, marital practices have crucially informed our comprehension of modernisation, family formations and moral panics. This article explores the impact of new forms of legal availability on marriage, family and kinship among the metropolitan middle classes. It ethnographically engages with important structural shifts reflected in the intimate lives of Hindu couples, but also foregrounds a cautious narrative of newly imagined jural relations. 相似文献

The ellobiid Ellobium scheepmakeri (Petit de la Saussaye, 1850) is reported from the banks of the Selangor River estuary, 57 years after it was first collected in Peninsular Malaysia. It was found in abundance under logs in the dryland mangrove forest of a dominantly Nypa swamp at the upper reaches of the Kuala Selangor estuary where sediment pore water salinity was recorded at 6–7 ppt. 相似文献

Aristolochia Subgen. Pararistolochia ( Hutch. & Dalz. ) O. C.
Schmidt, a smallest one among so far known three subgenera in the genus, often
treated as a separate genus, is composed of only nine species from Tropical
Africa (8 species)and Tropical Asia ( l species). This work deals mainly with the
system and taxonomic treatment as well as distribution based on the herbarium
materials form British Museum (Natural History) (BM), National Botanical Garden of Belgium(BR), Royal Botanic Gardens of Kew(K) and Laboratoire de
Phanerogamie of Paris(P). Three sections in the subgenus are described as new
by the number of anthers and its arrangement. Also two names, Pararistolochia
zenkeri (Engl.) Hutch. & Dalz. and P. macrocarpa (Duch.) Poncy var.
soyauxiana(Oliv. )Poncy, are reduced to synonyms of A. macrocarpa Duch.; andone name, A. preussii Engl., is reduced to a synonym of A. promissa Mast. 相似文献

This revision deals with the system, evolution, distribution, cytotaxonomy and
taxonomic treatment of the genus Aristolochia Linn. from E. & S. Asia, which covers Japan,
USSR (Far East), China, Viet Nam, Laos, Cambodia, Thailand, Burma, India, Bhutan, Nepal, Sikkim, Bangladesh and Pakistan. Total 2 subgenera, 7 sections, 4 series, 68 species and
1 variety (cultivated species not included) are recognized in this treatment, of which 3 sections and 2 species are described as new. In addition, 13 new synonyms and some new records to this region are also included.
Ystem Having estimated all the works dealing with the subdivision of the genus by
the previous authors, the system of O. C. Schmidt (1935) is chosen as the basis, with a change
of the sequence of the subdivisions. The subgenus Pararistolochia (Hutch. & Dalz.) O. C.
Schmidt, which has indefinite stamens and gynandrous lobes, seems to be better considered as
the most primitive one in the genus, while the subgenus Siphisia (Raf.) Duch., which has definite stamens and gynandrous lobes, anthers arranged in 3 pairs and more modifications of
the perianth, seems to be the most advanced one. The perianth of the subgenus Siphisia has differentiated into several types, and it is more rational using this character to classify sections
than lobes of the gynostemium. In this way, three new sections has been established. A suggested system of the genus is summarized as follows:
Subgen. 1. Pararistolochia (Hutch. & Dalz.) O. C. Schmidt
Subgen. 2. Aristolochia: Sect. 1. Aristolochia (2 series), Sect. 2. Gymnolobus Duch.
Subgen. 3. Siphisia (Raf.) Duch.: Sect. 3. Pentodon Klotz, Sect. 4. Odontosiphisia J. S.
Ma, Sect. 5. Leptosiphisia J. S. Ma, Sect. 6. Nepenthesia Klotz., Sect. 7. Obliquosiphisia J. S.
Ma, Sect. 8. Siphisia (2 series).
Evolution According to the character analysis of the genera of Aristolochiaceae, the evolutionary trends of the family are proposed as follows: 1, the perianth from double to single,
from cup-like to tubular, 2, stamens from indefinite to definite, from separate from pistil to
united into a gynostemium with pistil, which is a major evolutionary line in the family, 3,
ovary from half-superior to inferior, and 4, fruit from a follicle to a capsule. It is evident
that the genus Aristolochia, with a tubular perianth, stamens 6, a gynostemium, an inferior
ovary and a capsule, is in highly advanced position in the family. The subgenus Pararistolochia, which has more stamens and more lobes of gynostemium, is very similar to the genus
Thottea Rottb. and thus better considered as the most primitive subgenus in the genus. The subgenus Siphisia, which has definite stamens (6) in 3 pairs and 6 lobes of gynostemium as well
as the polyploid feature (2n=4x=28), is the most advanced subgenus. As a result of the character analysis, the evolutionary trends of the subgenera in the genus, which are in accordance
with those of the family, are proposed as follows: 1. stamens from indefinite to definite, and
2. gynostemium lobes from more to less.
Distribution The more primitive subgenus Pararistolochia is only distributed in West
Africa (except 1 species in Malesia), the subgenus Aristolochia in the tropical and subtropical
regions, rarely in the temperate one, and the most advanced subgenus Siphisia occurs mainly
in E. Asia, occasionally in N. America. The result of this work shows that the Hengduan
Mountains is the second center of distribution after South America. The second center of distribution is of following features: 1. complex composition of taxa, among 3 subgenera and 8
sections, 2 subgenera and 7 sections have been recorded here, 2. rich in species, more than
half of the total E. & S. Asian species, i.e. about 42 species have been found in this region, and
3. numerous endemics, more than 85 percent of the total number of species in the region, i.e.
about 35 species, are endemic.
Cytotaxonomy and taxonomic treatment The known chromosome numbers in 43
species, with 34 reported by Gregory (1956) and Fedorov (1969), together with 9 species newly
reported in this work, show that Subgen. Aristolochia with 2n=2x=14, rarely 12, is apparently
more primitive than Subgen. Siphisia with 2n=2x=28. 相似文献
