1. Occurrence of Conjugated Linolenic Acids in Purified Soybean Oil - Kinami, Tomohisa; Horii, Naoto; Narayan, Bhaskar; Arato, Shingo; Hosokawa, Masashi; Miyashita, Kazuo; Negishi, Hironori; Ikuina, Junichi; Noda, Ryuji; Shirasawa, Seiichi
A high-performance liquid chromatographic (HPLC) method is described for the determination of conjugated linoleic acids (CLA) and conjugated linolenic acids (CLN).

2. Feeding habits of stone flounder Platichthys bicoloratus larvae in Mutsu Bay, Japan - Takatsu, Tetsuya; Suzuki, Yuusuke; Shimizu, Akiko; Imura, Kazuo; Hiraoka, Yuko; Shiga, Naonobu
To clarify the feeding strategy of pelagic larvae of stone flounder in Mutsu Bay, the dietary composition and prey size was investigated from February to April during 1989–1999.

3. Annual variation of potential predation impacts on larval and juvenile marbled sole Pseudopleuronectes yokohamae by sand shrimp Crangon uritai in Hakodate Bay, Hokkaido - NAKAYA, Mitsuhiro; TAKATSU, Tetsuya; JOH, Mikimasa; NAKAGAMI, Masayasu; TAKAHASHI, Toyomi
An investigation was conducted to evaluate the annual variation in potential predation impact (PPI) on larval and juvenile Pseudopleuronectes yokohamae by Crangon uritai in Hakodate Bay using predator–prey size relationships.

4. ???????????????? - ??, ??; ??, ??; ??, ??; ??, ?; ??, ??; WAKAYAMA, KEN-ICHI; FUJIMORI, YASUZUMI; ITAYA, KAZUHIKO; MURAKAMI, OSAMU; MIURA, TEISUKE
The SELECT analysis with maximumlikelihood method was used to fit the different functional models, thenormal, lognormal, and bi-normal model.

5. Factors affecting egg predation in Black-tailed Gulls - Kazama, Kentaro
Factors affecting the probability of gulls allowing the crows to attack their nests or depredate their eggs and the probability of eggs being taken were studied by direct observation and egg census, respectively.

6. Respiration in marine pelagic copepods: a global-bathymetric model - Ikeda, Tsutomu; Sano, Fumikazu; Yamaguchi, Atsushi
Historical global respiration datasets of epipelagic copepods and recent bathymetric respiration datasets of mesopelagic, upper- and lower bathypelagic and abyssopelagic copepods were combined to build a global-bathymetric respiration model by adopting two regression models (theoretical and empirical ones).

7. Evolutionary significance of prenuptial molting in female Pagurus hermit crabs - Wada, Satoshi; Ito, Atsushi; Mima, Azusa
Molting and breeding entail major energetic costs for female crustaceans.

8. Comparative study on enzymatic characteristics of trypsins from the pyloric ceca of yellow tail (Seriola quinqueradiata) and brown hakeling (Physiculus japonicus) - KISHIMURA, HIDEKI; TOKUDA, YUSUKE; KLOMKLAO, SAPPASITH; BENJAKUL, SOOTTAWAT; ANDO, SEIICHI
Trypsins from the pyloric ceca of two fish species, yellow tail (Seriola quinqueradiata) and brown hakeling (Physiculus japonicus) were purified by a series of chromatographic separations.

9. Michio J. Kishi answers a few questions about this month's new hot paper in the field of Environment/Ecology. - Kishi, Michio J.

10. Geographic variation in a predator-induced defense and its genetic basis - Kishida, Osamu; Trussell, Geoffrey C.; Nishimura, Kinya
To do so, we crossed male and female frogs from a “mainland” Japanese island having predaceous salamanders and a more isolated island not having predaceous salamanders and raised resulting offspring in the presence and absence of H.

11. Direct and Indirect Induction of a Compensatory Phenotype that Alleviates the Costs of an Inducible Defense - Iwami, Tadashi; Kishida, Osamu; Nishimura, Kinya
One induced phenotype is an adaptive defense behaviour, i.e., stasis at the bottom of water column, directly triggered by the predation risk.

12. Reciprocal phenotypic plasticity in a predator-prey interaction between larval amphibians - Kishida, Osamu; Mizuta, Yuuki; Nishimura, Kinya
In biological interactions, phenotypic change in interacting organisms induced by their interaction partners causes a substantial shift in some environmental factor of the partners, which may subsequently change their phenotype in response to that modified environmental factor.

13. Threshold dimorphism in ejaculate characteristics in the squid Loligo bleekeri - Iwata, Yoko; Sakurai, Yasunori
Male dimorphism has been thought to correlate with alternative reproductive behaviors.

14. Dependance of paternity rates on alternative reproductive behaviors in the squid Loligo bleekeri - Iwata, Y.; Munehara, H.; Sakurai, Y.
The mating behavior of captive Loligo bleekeri and the paternity of the resulting progeny were examined based on behavioral observations and genetic analyses.

15. Characterization of microsatellite markers in the squid, Loligo bleekeri (Cephalopoda: Loliginidae) - Iwata, Y.; Munehara, H.; Sakurai, Y.
Loligo bleekeri has a long spawning season and the size of mature males changes during the season: dimorphic (large/small) early in the spawning season and monomorphic (small) later in the spawning season.

16. Simple conjugation and outgrowth procedures for tagging vibrios with GFP, and factors affecting the stable expression of the gfp tag - Sawabe, T.; Fukui, Y.; Stabb, E.V.
Aim: Our goal was to develop a simple system for tagging wild-type marine bacteria with gfp.

17. Isolation and characterization of salmonid telomeric and centromeric satellite DNA sequences - Saito, Yasuhiro; Edpalina, Rizalita R.; Abe, Syuiti
Satellite DNA clones with a 37 bp repeat unit were obtained from BglII-digested genomic DNA of Masu salmon (Oncorhynchus masou) and Chum salmon (O.

18. Inferring the Evolutionary History of Vibrios by Means of Multilocus Sequence Analysis - Sawabe, Tomoo; Kita-Tsukamoto, Kumiko; Thompson, Fabiano L.
Overall, 14 distinct clades were recognized using the SplitsTree decomposition method.

19. Purification of multiple vitellogenins in grey mullet (Mugil cephalus) - Amano, Haruna; Fujita, Toshiaki; Hiramatsu, Naoshi; Sawaguchi, Sayumi; Matsubara, Takahiro; Sullivan, Craig V; Hara, Akihiko
These Vgs were subsequently purified from the serum of estradiol-treated mullet by combining several types of chromatography columns (anion exchanger, hydroxylapatite, immunoadsorbent column, and gel filtration).

20. Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene - Kim, W. -S.; Oh, M. -J.; Nishizawa, T.; Park, J. -W.; Kurath, G.; Yoshimizu, M.
Glycoprotein (G) gene nucleotide sequences of four Korean isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed to evaluate their genetic relatedness to worldwide isolates.
