We genotyped 23 Y-STR loci（DYS576, DYS389 I, DYS448, DYS389 II, DYS19, DYS391, DYS481, DYS549, DYS533, DYS438, DYS437, DYS570, DYS635, DYS390, DYS439, DYS392, DYS643, DYS393, DYS458, DYS385a/b, DYS456, and GATA-H4） ...We genotyped 23 Y-STR loci（DYS576, DYS389 I, DYS448, DYS389 II, DYS19, DYS391, DYS481, DYS549, DYS533, DYS438, DYS437, DYS570, DYS635, DYS390, DYS439, DYS392, DYS643, DYS393, DYS458, DYS385a/b, DYS456, and GATA-H4） in a sample of 109 unrelated male Chinese people residing in Minnan area and compared the results with those from our previous study on 12 Y-STR. The haplotype diversity and the discrimination capacity of the 23 Y-STR reached 0.9903 and 0.9725, respectively, and the genetic diversity for each locus ranged from 0.321（DYS391） to 0.955（DYS385）. Besides, we observed a strong correlation between the number of Y-STR markers and the substantial improvement of forensic parameters used to discriminate between individuals. The results indicated that these highly polymorphic Y-STR markers were useful for human identification in forensic cases and paternity tests within the Minnan Han Chinese population.展开更多

Seasonal variations of photosynthetic parameters of marine phytoplankton were measured together with determination of Chl a and carbon content, Experimental results indicated that the average carbon-specific carbon accumulation rate is 0.85 d<sup>-1</sup>, mean primary productivity is 0.55 g C （m<sup>2</sup>d）<sup>-1</sup>. Temperature effect on the growth of the algae can be described by the modle of Goldman and Carpenter. Supplementation of nutrients brought up by the upwelling in summer caused the observably higher primary productivities in autumn.展开更多
