Notes: Abstract Chemical properties of waters and their seasonal changes were studied in Mizorogaike Pond, a system of pond and floating mat. The following six sites including contrasting habitats and water conditions were monitored to assess nutrient dynamics in the system: 1) a pool on the mat, 2) margin of aSphagnum cuspidatum community, 3) an artificial ‘well’ (water layer beneath the floating mat), 4) aMenyanthes trifoliata community in a hollow, and 5) & 6) two sites in the open water. On the floating mat, the water around theSphagnum community had lower pH values, while that in theM. trifoliata community had higher pH values. This difference was related to the influence of flood water, the extent of which was determined by the microtopography. Seasonal changes in water chemistry on the mat suggested that pond water flooding the mat in late autumn and winter is important for the nutrient supply to the mat surface vegetation in this system. Water chemistry of the ‘well’ suggested that the diffusion of inorganic nitrogen occurs from beneath the peat layer. Two types of cluster analysis based on the mean values for chemical variables and the patterns of fluctuation in these variables were performed. The six sites were classified into similar groups which were identified by water type (pool, hollow, well and open water) by both types of analysis. The results showed that a common kind of perturbation should operate in determining the status of nutrient dynamics in the various water types.

Notes: The FXIIIA polymorphism was studied in a Japanese population using agarose gel isoelectric focusing and agarose gel electrophoresis, combined with immunoblotting onto nitrocellulose membranes. The correspondence of patterns between the two methods was confirmed by two-dimensional electrophoresis. A rare phenotype, FXIIIA 4-1, was detected in one individual besides the three common phenotypes FXIIIA 1, 2-1, and 2. This rare phenotype was identified with the originally reported FXIIIA 4-1 in Melanesians. Our results indicate the possibility that the FXIIIA*4 allele may be distributed widely in world populations.
