1. By using different primers, the intraspecies variation of RAPD profiles was different.

2. Spectral characteristics between intraspecies reflect the component constancy and habitat difference.

3. The competition, especially the intraspecies competition, is the mechanism and motivity of biological existence and evolution.

4. It was suggested that the geometry morphology plasticity highly responsed to intraspecies competition in different density.

5. The anova analysis showed that:all materials between species and intraspecies both reached the extremely obvious difference or significantly difference.

6. Comparisons of the characteristics of different anastomosis groups from shape, pathogenicity, physiology, to bio-chemistry,[http://] suggests the existence of intraspecies differentiation.

7. Research development of germplasm resources of Fructus Amomi was reviewed in the aspects of species resource, geographic distribution, intraspecies variation, and tissue culture.

8. Viral-mediated mortality may not only affect algal species succession, but also affect intraspecies succession, the abundance and diversity of host cell communities in natural marine environments.

9. Thus we can further assume that there are indications of differentiation in intraspecies among periodic B. malayi from different endemic areas in our country.

10. The result also showed there was some difference in DNA content to the same ploidy between different species and different strains of the intraspecies.

11. Objective: To investigate the content variety of 3 kinds of tanshinone among intraspecies of Salvia miltiorrhiza Bunge.

12. DNA sequence variation in the same species of animals was only observed in human, donkey and mouse, and the number is less than 4 (1.3%), other animals showed no intraspecies variation.
