Reproductive habits of a temperate filefish, Paramonacanthus japonicus, were studied on a rocky reef at Tsuyazaki, Fukuoka, Japan, from 1989 through 1990. Males had territories of 30–70m2 and defended them from conspecific males and potential egg predators such as another filefish, Stephanolepis cirrhifer. Egg masses were found on the sandy bottom in male(More)
We devised a multiplex polymerase chain reaction (PCR) amplification and loading system for the convenient typing of 168 short tandem repeat (STR) polymorphic markers in a commercially available screening primer set for human linkage analysis. We genotyped all these 168 STR loci with 32 healthy unrelated Japanese, calculated allele frequencies at each STR(More)
Reproductive behavior of the threadsail filefishStephanolepis cirrhifer was studied at Kashiwajima, southern Shikoku, Japan. This species spawned in pairs on the sandy bottom, the eggs being scattered over an area of about 15 cm in diameter and attached to sand particles. After spawning, males departed immediately, while the females remained at the site to(More)
Reproductive ecology of the black reef leatherjacket, Eubalichthys bucephalus (Monacanthidae), was studied in temperate Australia. The fish lived in the same heterosexual pairs, and each pair shared a home range composed of rocky reefs and boulders where they reproduced and fed on sponges. Spawnings were conducted in pairs, and fertilized eggs were attached(More)
Reproductive behavior of the Japanese filefish, Rudarius ercodes, was studied at the rocky reef off Koinoura, northern Kyushu, Japan, between June and October 1989. Aggressive display was observed between males, but they were not territorial. Males had four types of courtship behavior: vibrating, tail bending, leaning and nuzzle. Spawning occurred early in(More)
Reproductive ecology of the crosshatch triggerfish, Xanthichthys mento (Balistidae) was studied at Hachijojima, Izu Islands, Japan. Males established territories and repeatedly chased females passing nearby. There were 1–3 females in each male's territory before spawning and during egg care. This species spawned in pairs on the sandy bottom. Eggs were(More)
We report that male pufferfishes (Torquigener sp., Tetraodontidae) constructed large geometric circular structures on the seabed that played an important role in female mate choice. Males dug valleys at various angles in a radial direction, constructing nests surrounded by radially aligned peaks and valleys. Furthermore, they created irregular patterns in(More)
Spawning behavior of the pygmy leatherjacket Brachaluteres jacksonianus was studied in southeastern Australia. Prespawning females thrust the snout repeatedly into spawning substrata, while males exhibited courtship display and nuzzled the female’s face. The females and males touched their abdomens in pairs and released gametes. No parental egg care was(More)
The machine-learning-based dynamic performance control of routers is proposed to reduce router power consumption. In order to achieve fast adaptability to catch the changing traffic characteristics, we introduce two sequential classification measures; normalization with performance thresholds, and periodic staggered use of learning machine sets in(More)
