1. Bryophyte is sensitive to acid sedimentation.

2. This article summarized the indicating function of bryophyte to air pollution.

3. Bryophyte is widely accepted as one of the most susceptible indicators for monitoring air pollution due to its characteristics of sensitivity, accuracy, and directness.

4. The results also show that bryophyte life forms in Sangong River Valley are relatively rich, which indicates the biodiversity characteristics of bryophyte in this valley.

5. Called a bryophyte, the plant belongs to the same family as mosses and liverworts.

6. Protonema ( pl . protonemata ) The young bryophyte gametophyte that develops following spore germination.

7. The study of bryophyte in Xinjiang has become relatively late.

8. Therefore it is of importance for understanding bryophyte diversity and its characteristics to study systematically on Inner Mongolia Amblystegiaceae's taxonomy, floristics and distribution character.

9. Especially, the research of bryophyte ecology and bio diversity are still in blank field.

10. Bryophyte is a kind of higher plants with small size and simple structure, being the transitional form from aquatic to terrestrial and the most original group of existing higher plants.

11. From 307 bryophyte specimens collected from Xiaoxi National Nature Reserve Hunan province, 41families, 83 genera, 152 species, 4 subspecies and 3 varieties have been identified.

12. Bryophyte can sensitively response to the air and heavy metal pollution, and is a kind of bio-indicators.

13. Current cryptogamic research areas include: diatoms, algae, fungi, lichens, bryophytes and ferns.

14. This paper mainly deals with the present situation, problems and prospect of bryophyte research in Xinjiang.

15. This paper is based on a study of 52 samples and specimens of bryophyte collected from 5 active travertine sites at Yorkshire Dale National Park, U. K.

16. DNA is the carrier of genetic information and sequencing and comparison of DNA nucleotides are the thorough and ideal method for bryophyte molecular phylogenesis.

16. try its best to gather and create good sentences.

17. In this paper, coefficient of similarity analysis was used to study flora similarity of mountain bryophyte in Xinjiang.

18. The heterogeneity level of microenvironment conditions under the forest was high, the number of bryophyte patch was numerous, which means the fragmentation level was high.

19. This paper is based on a study of 52 samples and specimens of bryophyte collected from 5 active travertine sites at Yorkshire Dale National Park, U.

20. It has a very strong ability of holding and absorbing water, especially the epiphytic bryophyte can intercept a great deal of rain, and its function in water circulation is very obvious.
