Title Rosemary Rhagada COI sequences
Downloaded 26 times
Description 666 bp fragments of the mitochondrial gene Cytochrome Oxidase subunit I from 263 snails collected from the main study area. The first number in the title is the transect number, the second is the site number and the third is the individual number (Transect_Site_Individual). The dataset is edited and aligned. Sequences with the same name followed by the letter B were collected from the same site on different occasions (i.e., 8_1_4 and 8_1_4B). The sequences have been edited and aligned.
