| Research Abstract |
In this study, I estimated the probability density function(PDF) of six taxonomic groups of bacteria in Lake Biwa. Summary statistics were obtained from the PDF, and the relationships with environmental variables were analyzed. From the data, I could not detect significant differences among cell volumes of the six taxonomic groups. On the other hand, cell volumes decreased significantly with increasing temperature. Cell size of bacteria is an important trait that controls function of bacteria in aquatic ecosystems. These results contribute to promote our understanding of bacterial community and the responses to global climate change.
