The effect of Lactobacillus (LAB) abundance on the microbiome and lifestyle of Drosophila Melanogaster has been studied multiple times over the years with varying conclusions. The works of Henry et al and Walters et al differ in their results despite having similar research done along the same cline in the East Coast. I will analyze the differences between the raw data of these studies in order to come to a more definitive conclusion about the relationship between latitude and LAB abundance. Henry et al also includes information and raw data about the microbiomes of flies, frass (fly feces), and the flies diet. I will be analyzing the raw data from Henry et al as well, to determine the relationship between these three elements. Together, these analyses will help me to learn why these similar studies came to such different conclusions about the effects of LAB and latitude as well as any relatedness there is between the microbiomes of fly, frass, and diet microbiomes to each other and the geographic cline.
