The present paper intends to introduce a one-dimensional physical-biological model developed by the author in hoping to enhance the thorough understanding on the plankton ecosystem in the Yellow Sea,that is,the annual cycle of its vertical structure in the eastern area of the South Yellow Sea.

The polymorphism of ten biochemical genetic loci including HB,KE,TF,PTF,PA,AMY 1,ALP A,ALP B,RBC-LDH 1,S-LDH 1 for Qinghai east yellow cattle were investigated by polyacrylamide gel electrophoresis and flame photometer.

chaidamu yellow cattle and 256 Qinghai east yellow cattle were used to investigate the polymorphism of haemoglobin by means of polyacrylamide gel electrophore sis.

We studied when the YSWC and its accompanying cold water body were formed ,and how did they evolve after formation based on foraminiferal communities in the Southeastern Yellow Sea Mud.

Variations in diet composition and feeding intensity of small yellow croaker Larimichthys polyactis Bleeker in the southern Yellow Sea and northern East China Sea;
