Lipids of Neocalanus cristatus and Eucalanus bungii (C3 to adults), collected in March, May, and December from various depths (0-2000m) were studied in the Oyashio region, western North Pacific. Total lipid and wax ester contents of younger N. cristatus stages increased during the development, being higher in May than in March and December. Major fatty acids of younger N. cristatus were 16:0, 2...

The development of complex multispecies communities such as biofilms is controlled by interbacterial communication systems. We have previously reported an intergeneric communication between two oral bacteria, Streptococcus cristatus and Porphyromonas gingivalis, that results in inhibition of fimA expression. Here, we demonstrate that a surface protein, arginine deiminase (ArcA), of S. cristatus...

the fishes of capoeta genus are living in different fauna regions of iranian freshwater fishes. the parasitological studies of these fishes are important on subjects of ecology and life cycles in different fishes. the aim of this study was to study the parasites of capoeta spp. in halil-rud river, kerman province. samples were collected from the freshwater fishes (between oct. 2007 to sep. 2008...

One of the classic examples of an exaggerated sexually selected trait is the elaborate plumage that forms the train in male peafowl Pavo cristatus (peacock). Such ornaments are thought to reduce locomotor performance as a result of their weight and aerodynamic drag, but this cost is unknown. Here, the effect that the train has on take-off flight in peacocks was quantified as the sum of the rate...

A manometric method for measuring photosynthesis in marine algae is described. Photosynthesis in the red alga Gigartina harveyana is shown to be similar in all important respects to photosynthesis in Chlorella and other Chlorophyceae.

Rabbit antisera to newt (T. cristatus) globin were produced by repeated injections of globin and antiglobin antibodies purified by chromatography on globin-Sepharose 4B. Ouchterlony and SDS PAGE analysis indicated that the material eluted from the affinity column was rabbit IgG. The antiglobin antibodies tested by immunodiffusion and ELISA cross-reacted with native hemoglobin and globin from T....

When significant mortality of the bathyal spatangoid echinoid Paleopneustes cristatus occurred under laboratory conditions, we investigated the cause and course of the disease by culturing and identifying internal pathogens, then experimentally infecting healthy urchins with isolates of the suspected disease organism. The pathogen was determined to be the gram-negative halophilic bacterium Vibr...
