A new species of <Emphasis Type="Italic">Sebastes</Emphasis> (Scorpaeniformes: Scorpaenidae) from the Pacific coast of southern Japan 总被引:1,自引:1,他引:0
A new rockfish, Sebastes kiyomatsui, is described on the basis of 13 specimens from the Pacific coast of southern Japan. The new species resembles S. scythropus in having two sharp preorbital and robust preocular, supraocular, and postocular spines, but differs from the latter in having a black blotch on the opercle not extending to the subopercle, indistinct crimson marks on the body, blackish region of the oral cavity reaching to the prevomer and palatine, blackish tongue, a small ridge on the upper edge of the lachrymal, somewhat larger orbit, somewhat lower caudal peduncle, and seven lower unbranched pectoral fin rays. Sebastes kiyomatsui is a deep water (ca. 250m) inhabitant. 相似文献

Four species belonging to the genus Cercospora and allied genera were newly added to the Japanese mycoflora. They are Cercospora plantaginis on Plantago asiatica, Pseudocercospora asystasiae on Asystasia gengetica, P. cassiae-fistulae on Cassia fistula, and Pseudocercosporella ranunculacearum on Clematis grata var. ryukyuensis. 相似文献

Previously we showed that strains of human polyoma virus JC among the Navajo in New Mexico, speakers of an Athapaskan language in the Na-Dene language phylum, and among the Salish people in Montana, speakers of a language of the Salishan group in the Amerind family, were mainly of a northeast Asian genotype found in Japan (type 2A). We now report partial VP1-gene, regulatory region, and complete genome sequences of JC virus (JCV) from the Guaraní Indians of Argentina. The Tupí-Guaraní language represents the Equatorial branch of the Amerind language family proposed by Greenberg ([1987] Language in the Americas, Stanford: Stanford University Press). The partial VP1 gene sequences of the Guaraní revealed several variants of strains found in northeast Asia (Japan), as did the Salish. In contrast, the strains in the Navajo largely conformed to the prototype type 2A sequence (MY). Phylogenetic reconstruction with both the neighbor-joining and maximum parsimony methods utilized three complete Guaraní JCV genome sequences, three genomes from the Salish people, and 27 other complete JCV genomes, including three from the Navajo and three from Japan. Both trees showed that all type 2A JCV strains from the North and South Americans are closely related phylogenetically to strains in present-day Japan. However, variant sites in the coding regions, the T-antigen intron, and the regulatory region link the type 2A strains in Amerind groups (Guaraní and Salish), but differentiate them from those in a Na-Dene-speaking (Navajo) population. The data suggest separation from a population ancestral to modern Japanese, followed by a second division within the ancestral group that led to Amerind- and Na-Dene-speaking groups. The data cannot, however, localize the latter split to the Asian mainland (two migrations) or to North America (one migration). 相似文献

The application of sieving techniques to bulk samples from the Ashizawa Formation, Futaba Group (Lower Coniacian) of northeastern
Honshu, Japan, has yielded well-preserved mesofossil assemblages comparable with those recently described from eastern North
America, Europe, and central Asia. Among the most abundant and distinctive components of these assemblages are fusiform fruits
that are assigned here to a new genus and species, Hironoia fusiformis gen. et sp. nov. The fruits developed from an epigynous ovary with three to four locules. Each locule bears one seed and
has a distinctive dorsal germination valve. These features of the fruit, along with the adnate calyx, indicate an affinity
to extant Cornales and specifically the Cornaceae sensu lato. The recognition of an unequivocal cornalean fruit in the Early
Coniacian–Early Santonian of Japan provides the earliest record of this group in the fossil record. It also establishes a
minimum age for the early divergence of the asterid clade, a major group of living angiosperms comprising more than a third
of all species of extant flowering plants.

The goal of this study was to calculate the average CO2 emissions for manufacturing three commodity plastics, polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC)
in Japan. The CO2 emissions were calculated from cradle to gate, excluding the calcination processes after use. As the results, the followings
were observed:
1) The gross CO2 emissions for the manufacture of plastics in Japan were 1.3, 1.4, and 1.7 kg-CO2/kg-PE, PP, and PVC, respectively. These mainly reflected the difference of CO2 emissions for the in-house electricity generation. 2) The CO2 emissions for the electricity used for manufacturing PVC were higher than that used for PE and PP, because additional electricity
was required for the electrolysis to produce chlorine. The gross electricity consumption for manufacturing PVC was 1.3 kWh/kg-PVC,
and the other plastics consumed 0.5 kWh/kg-Products. In addition, the effects of energy saving were studied using a projected
gas-diffusion electrode for the electrolysis of salt on the reduction of CO2 emissions. It was estimated that the reduction in CO2 emissions was 7% compared with the present PVC manufacturing processes. 相似文献

Utilizing a range of ethnographic data from anAIDS hotline, a women's shelter, a night club,AIDS campaigns, news articles, and interviewswith health bureaucrats, this paper exploresthe history of AIDS in Japan and the ways inwhich official practices reproduce systems ofdomination. This paper examines the officialcategories of ``foreign woman' and``prostitution' as discursive strategies ofcontainment, and argues that nationalistdiscourses and representations of sexuality areclosely linked in maintaining relations ofpower. 相似文献

Exobasidium symploci-japonicae var. carpogenum, causing Exobasidium fruit deformation on Symplocos lucida collected in Fukuoka Prefecture, Japan, is newly described based on morphological observations of hymenial structure and mode of basidiospore germination. This new variety differs morphologically from the type variety, particularly in the septal number of basidiospores and in the shapes and sizes of conidia formed on the medium. Colonies of this new variety are also distinguishable from those of the type variety by yeast-like growth, morphology, and color of colonies.Contribution no.178, Laboratory of Plant Parasitic Mycology, Institute of Agriculture and Forestry, University of Tsukuba, Japan 相似文献

The ratios between the indices of relative abundance for different trophic life forms have been used to characterize bionomical types of a rocky intertidal zone. It has been shown that the distribution of life forms is determined by the geomorphological peculiarities of the surveyed intertidal areas. A brief critical historical review has been provided of the terms bionomy and bionomical type. 相似文献
