群落

Biological characters such as morphological character, growth character, habitat, community and geographical distribution of Picrorhiza scrophu1ariflra Pennell in northwest of Yunnan were studied, and the reasons of environmental deterioration, man-made sabotage, own reasons of Picrorhiza scrophu1ariflora Pennell in Yunnan were analyzed as well. The development and protecting strategy to improve protention, improve base study, enlarge protective area and protect native reasource, reintroduction, rational utilization and effective protection were put forward.

"The fact that the community contains only one species stands one of the basic tenets of microbial ecology on its head," says Carl Pilcher, director of the NASA Astrobiology Institute, who was not involved in Chivian's DNA analysis but whose colleagues made the initial discovery that there were microbes living in this particular fissure two years ago.
