The morphology of eggs and larvae of Awaous melanocephalus is described. The eggs measured 0.33–0.35 mm in long-axis diameter and 0.32–0.34 mm in short-axis diameter. Newly hatched larvae (0.90–0.99 mm in notochord length, NL; 0.93–1.04 mm in total length, TL) were poorly developed, lacking a mouth and having a large yolk sac and unpigmented eyes. The mouth(More)
Reproductive biology and morphology of eggs and early larvae of the sicydiine goby Stiphodon percnopterygionus were investigated on Okinawa Island, southern Japan. Spawning season was estimated as being from May to December. Standard length at maturity was approximately 20 mm in both sexes, and batch fecundity was approximately 1000–10 000 per female. The(More)
Larvae and juveniles of six species of Luciogobius were collected at Aritsu Beach on Okinawa Island using a small seine. Postflexion larvae were dominant during sampling and were collected when they approached the shoreline adjacent to or at the entrances to their adult habitats prior to settlement. Standard lengths of postflexion larvae ranged from 5.4 to(More)
Bambusa arnhemica is a bamboo species endemic to northern Australia. We isolated and characterized nine microsatellite loci from this species. The number of alleles ranged from 2 to 16 with an average of 6.8, and expected heterozygosities from 0.40 to 0.84 with an average of 0.69. The markers described here will be useful to investigate clump structure,(More)
Egg masses of Luciogobius ryukyuensis were found in spawning grounds around the lowest reach of the adult’s habitat in the tidally influenced area of streams on Okinawa Island. The eggs were attached to the underside of stones and were cared for by a solitary male fish. The number of eggs within an egg mass was 191–1368. The eggs were elliptical, measuring(More)
We present the analysis and interpretation of a sample of eight ASCA observations of Broad Absorption Line Quasi-Stellar Objects (BALQSOs). This is the first moderate-sized sample of sensitive BALQSO observations above 2 keV, and the BALQSOs in our sample are among the optically brightest known (B = 14.5–18.5). Despite the ability of 2–10 keV X-rays to(More)
Titles and authors of oral and poster presentations made during the 44th annual meeting at Hirosaki, Aomori (29 September–2 October 2011) are listed on the ISJ website ( The following papers were published in Japanese Journal of Ichthyology Volume 58, Number 2 on 7 November 2011, and English abstracts are(More)
The hydrophobic dyes tetrabromophenolphthalein ethyl ester and 2,6-dichlorophenolindo-phenol are proposed as visual indicators for two-phase titrations. The aqueous phase is colourless throughout the titration and these indicators make it possible to detect the end-point of the titration by the colour of one or the other phase. The indicators allow the(More)
A titration method was developed for the determination of diphenhydramine, quinine, neostigmine, sparteine, strychnine, homatropine, atropine, physostigmine, and procaine in aqueous solution. Tetraphenylborate was used as a titrant with tetrabromophenolphthalein ethyl ester as an indicator in the presence of organic solvent. End-point detection was based on(More)
