| Outline of Final Research Achievements |
The environmental DNA technique was applied to cichlid fish community in Lake Malawi to establish a method for measuring divesity of the community. Sequence data of D-loop and ITS regions were collected from 103 sympatric fish species at the beggining of the study period. Using the sequence data, an eDNA primer targetting D-loop region of cichlids was designed, with which the efficient sampling methods specific to the focal lake was established. Water samples were collected from 12 sites of 6 district of the lake, which differ from each other in cichlid diversity. As interspecific variation in DNA sequence was found to be so poor, I am now trying to design another universal primers that amplify ITS region, with which cichlid diversity will be estimated.
