| luxa gene of light organ symbionts of the bioluminescent fish acropoma japonicum (acropomatidae) and siphamia versicolor (apogonidae) forms a lineage closely related to that of photobacterium leiognathi ssp. mandapamensis. | a molecular phylogenetic analysis of luxa gene sequences of light organ symbionts of the fish acropoma japonicum (acropomatidae) and siphamia versicolor (apogonidae) revealed that the sequences were related to those of photobacterium leiognathi ssp. mandapamensis, which is not known to occur as a light organ symbiont among bioluminescent p. leiognathi clades. the presence of another lux gene element, luxf, coding for nonfluorescent protein, provided additional support for the identity of the lig ... | 2006 | 16842343 |
| phylogenetic diversity and cosymbiosis in the bioluminescent symbioses of "photobacterium mandapamensis". | "photobacterium mandapamensis" (proposed name) and photobacterium leiognathi are closely related, phenotypically similar marine bacteria that form bioluminescent symbioses with marine animals. despite their similarity, however, these bacteria can be distinguished phylogenetically by sequence divergence of their luminescence genes, luxcdab(f)e, by the presence (p. mandapamensis) or the absence (p. leiognathi) of luxf and, as shown here, by the sequence divergence of genes involved in the synthesi ... | 2007 | 17369329 |
| [spatial heterogeneity of trichiurus japonicus and small-scale fish in east china sea and their spatial relationships]. | based on the investigation at 121 positions in east china sea in 2001 autumn, this paper analyzed the spatial heterogeneity of hairtail (trichiurus japonicus) and seven kinds of small-scale fish (setipinna taty, collichthys lucidus, champsodon capensis, amblychaeturichthys hexanema, acropoma japonicum, benthosema pterotum and apogon lineatus), and the spatial relationships among them. the results indicated that the semivariogram curve of hairtail was very similar to those of apogon lineatus, amb ... | 2005 | 16011172 |
| chemical and biological properties of lipopolysaccharides from symbiotic luminous bacteria from several luminous marine animals. | the chemical and biological properties of lipopolysaccharides (lps) in five strains of symbiotic luminous bacteria isolated from four species of luminous marine fishes, coelorhynchus kishinouyei (ck-1), chlorophthalmus albatrossis (ca-1), ventrifossa garmani (vg-1), and acropoma japonicum (aj-1b), as well as from a luminous squid, doryteuthis kensaki (dk-1) were examined. the lps isolated from these symbiotic luminous bacteria were characterized by the absence of 2-keto-3-deoxyoctonate, known to ... | 1983 | 6865804 |
| [distribution of nekton stock density and its community structure in taiwan strait in summer and autumn]. | this research was conducted based on the bottom trawl surveys in summer and autumn. an analysis on the stock density and community structure of nekton in taiwan straits indicated that the average stock density was 8.50 kg x h(-1) in summer and 6.94 kg x h(-1) in autumn. the species number was 80 in summer and 91 in autumn, and the abundance, species diversity index, and evenness index were all higher in autumn than in summer. the average species diversity index was 2.0466 in summer and 2.3964 in ... | 2005 | 16422520 |
| [effects of macro-jellyfish abundance dynamics on fishery resource structure in the yangtze river estuary and its adjacent waters]. | based on the bottom trawl survey data in may 2007 and may and june 2008, this paper analyzed the effects of the abundance dynamics of macro-jellyfish on the species composition, distribution, and abundance of fishery resource in the yangtze river estuary and its adjacent waters. from may 2007 to june 2008, the average catch per haul and the top catch per haul of macro-jellyfish increased, up to 222.2 kg x h(-1) and 1800 kg x h(-1) in june 2008, respectively. the macro-jellyfish were mainly distr ... | 2011 | 22384604 |
| [community structure of fish in zhoushan fishing ground and its adjacent waters in spring and summer]. | based on the investigation data of the fishery resources and environment in zhoushan fishing ground and its adjacent waters in august 2006 and april 2007, and by using multi-dimensional scaling (mds) and canonical correspondence analysis (cca), this paper studied the species composition and the characteristics of fish community in the area. in spring, a total of 62 fish species were captured, belonging to 56 genera, 36 families and 11 orders. the dominant species were amblychaeturichthys hexanem ... | 2012 | 22586985 |
| [ecological niche breadth and niche overlap of dominant species of fish assemblage in yangtze river estuary and its adjacent waters]. | based on the fishery resources data from the bottom trawl surveys conducted on the r/v beidou in the yangtze river estuary and its adjacent waters in june, august and october of 2006, the index of relative importance (iri) was measured to determine the dominant species of fish assemblage, and the niche indicators and their seasonal variations of the dominant species were analyzed. a total of 10 dominant species in the 3 survey cruises were recorded, which were divided into two groups by the bray ... | 2013 | 24380359 |
