9902219 Ward & PapkeMontana State University Investigations of bacterial speciation have been limited by techniques that are biased and limited in their abilities to resolve species. Modern molecular techniques in microbiology have the potential, now, to be used for natural history studies with microorganisms that are parallel to those used for higher plants and animals. This project would examine the influence of geographic isolation on the diversification of bacteria. It would evaluate evolutionary and ecological patterns of thermophilic cyanobacteria by evaluating 16S rRNA gene diversity from geographically distant thermal sites. Genotype of Synechoccus inhabiting hot springs in Yellowstone National Park will be compared with springs in New Zealand, Japan, and China as well as at Mt. St. Helens in the US.

蒙大拿州立大学细菌物种形成的研究一直受到技术的限制，这些技术在分辨物种的能力上存在偏见和局限。 微生物学中的现代分子技术现在有可能用于微生物的自然历史研究，与用于高等植物和动物的研究平行。 该项目将研究地理隔离对细菌多样化的影响。 它将通过评估地理上遥远的热站点的16S rRNA基因多样性来评估嗜热蓝细菌的进化和生态模式。 居住在黄石国家公园温泉的集水母的基因型将与新西兰、日本和中国以及山的温泉进行比较。圣海伦斯在美国
