They revealed that the preference of food type does not depend on the habitat in which it is presented. The genomic DNA of L. cuneata and the Methylobacteria growing on its leaves was analyzed with RAPD-PCR in order to evaluate the hypothesis that their genetic diversity will correlate with the geographical distance between the sample sites. The data does not support this relationship, however considerable genetic diversity was found amongst the samples. Due to the small sample size, further research is needed in this area. Co-occurrence of fish and mussel species in rivers upstream from three eastern Kansas reservoirs Brian Theel North America has the greatest freshwater mussel diversity in the world .
Mussels are a very endangered group.
In this study, I compared the presence or absence of mussels to their known hosts. During the days of June 8 to July 22 of 2000 we sampled 36 sites on three eastern Kansas rivers upstream from there reservoirs. I surveyed literature to discuss known hosts for mussels present and now extirpated from the Marais des Cygnes River. Future plans are to finish the data analysis for the rest of the sites on the three rivers.
