| Abstract: |
| It is known that the biometrics of brine shrimp cysts is of strain inherent.The analysis and comparison of the cyst characters for the identification of unknown cysts from different geographical origin become possible.In this paper,multivariate methods,mainly Principle Component Analysis(PCA) and Nonmetric Multi-dimensional Scaling(MDS),are used for the purpose.Good results are gained with the analysis of the published data and some row data from cyst size.It shows that multivariate methods can cluster the similar characteristics of batch cysts and make out impure or mingled cysts of different origin.Among others,MDS,with row data from the cyst measurement,can be easily used for the analysis of cyst ordination and comparison.The result demonstrates that the cysts of Chinese parthenogenetic brine shrimp are well discriminated by their geographic locations along the coastal China with larger size distributing in the south. |
